LIVE | HISTORY IN THE MAKING: SpaceX Polaris Dawn Crew Embarks on First-Ever Private Spacewalk

we want to make sure the crew takes helmets off and everything that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is microgravity everything's harder everything's on hard mode um and you don't just have natural convection so like I mean space station I think I've heard it a bunch of times Mike like you just constant noise of fans that's right almost yeah there's uh you've got to continually recycle that air um and one to help get rid of the CO2 right because as we're taking in that auction they're breathing out the CO2 and we need to to get that out of the system which is another important reason to have that air constantly circulating yeah um man that felt really quick that was it did that was that was that was really cool to to see them outside for the first time and there they were what they were actually doing out there is a bunch of pretty simple tests as it looked but like this is just learning how the heck do you move cuz like just moving around yeah in micro gravity is tough it is tough Dron Space X we're about 2 and a half minutes from T hand around when you're in your short sleeves like we're in inside the capsule and when you put on that space suit uh it it's much more challenging to to move around with that on yeah and what they were really doing was just kind of like you put your hand on on Skywalker and then you're changing your pitch you're doing translation up and down and everything and then the one that that I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah and I think one of the other things I thought was interesting is you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab on to or utilize versus the vertical one so simple things like that you know for us it talk about the horizontal rail versus the vertical and how much easier that was for her to grab onto or utilize versus the vertical one so simple things like that you know for us it not a big deal uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that you've be able to share with us throughout morning's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all of SpaceX and and really for for Humanity because it's just one of those small steps that's taken us that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime excellent all right good to see you thanks by all right so repress is continuing we're a little over 4 PSI right now again we're going to keep that going up until we're a little over eight and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole process like right after we got on orbit yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their cute zero g indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and uh let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there inting the teis in and out so like we'll get it back but um so yeah just the fact that the uh all four crew members were able to just go right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during you good we're good two good just heard a quick check in from them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at 8 and then we'll let it hang out there for a couple of minutes I'll let the thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the sup pressure starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for 1 hour and 13 minutes um it flew by so so quickly um pressure approaching one PSI on pp2 I'm I'm sure for shared and Sarah flew by even quicker yeah we just heard Jared call down we're coming up on one PS side for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core Arthur barrial that's going to come uh once we are done with the repress repress operation uh we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the P2 environment in the suit using nitrox before they get out Nitro being that same air mixture that you have in your scuba tank uh if got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there we're just going to keeping out should hopefully be getting video back from ground stations stand by for transition toess 2 at 8 Deal 3 here copy that SpaceX we're following along refres two at 8.3 yeah so once we transition to repress 2 once we're at about 8.3 PSI will stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we've got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hopefully just about a minute and a half or so away from ground station so might get those views back inside a dragon yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh PA refes to UPS check e1's good we're good F you and yeah that coms we're hearing a half PSI before we get the Le monitoring check 9 PSI have a continual checks with all four crew members to make sure that everyone is good um if the answer to one of those checks was no there would be an option in this repress sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depressurize now this repress it seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to tick up but we're going to pause at 9: we're going to do another cabin leak check so we should hear that momentarily we ref press two stop drag space with you and Eva repress to stop waiting 5 minutes for theral stabilization we're C that space we're tracking Fe awareness we do a positive refes rate we have 30 seconds into check like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness ppmc 1 decimal 35 halfway there suits are still flowing that oxygen um and in a few minutes we will begin to flow we do a flush uh of of nitro uh into the suits [Applause] all right we got our views back there they are it's a little sad to see that forward hatch closed again it's it's got to be really hard when they tell you it's time to go back in yeah just one more minute yep reminds me of when I was a kid swimming in the pool you know time to get out just one more minute I mean it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline Che through sh's good good you good C2 just passed 1.5 we're a couple minutes into our leak check you're you're seeing the pressure continue to tick off we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that is why you're going to continue to see the pressure tick up you heard Jared call out the P2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14.4 or so and I mean that's that's little bit lower than what we're walking around in now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah but after we get all the way up there we're going to do kind of a final flush of the suits using that Nitro uh the K was talking about uh that takes them out of that pure oxygen environment and that's one of the final steps before we'll feel hear that call from Arthur vva operations complete and that's when our clock's going to stop uh our space walk did start today at here at SpaceX in Hawthorne California and I'm Dan huitt from the communications team now the first Eva in history was performed in 1965 by Soviet Cosmonaut Alexi leonov followed just three months later by the first American spacewalk done by Ed White during the Gemini 4 Mission from those humble beginnings to walking on the surface of the Moon repairing satellites building space St in orbit space walks are really a core component of human space flight well Evas are well EST Lish procedures for NASA and other space agencies this will be the first Space Walk using commercially developed hardware and procedures and spacex's brand new Eva suits which we debuted earlier this year now we've tested extensively in vacuum Chambers here on Earth but this is the first time that the suits will encounter the vacuum of space and on board the dragon spacecraft right now is the Polaris Dawn crew starting off you got Mission Commander Jared Rook Isaac m Mission pilot Scott kid potit and for the first time ever we're excited about this two SpaceX employees Mission specialist Sarah Cooper Gillis and Anna Walker Menan who's serving as the mission specialist and medical officer for members of the crew have been orbiting Earth for two days since they lifted off from launch complex 39a at Kennedy Space Center on Tuesday September 10th it adds up to about 15 to 16 orbits around the Earth every single day in County on day two of the mission as you can see there on your screen Dragon fired its forward Draco bulkhead thrusters to send the spacecraft soaring higher than any dragon mission to date reaching the highest Earth orbit ever flown the crew uh topped out at more than 1,400 km breaking the record set by gmany 11 a half century ago when that spacecraft reached 13 excuse me 1,373 kilm this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 since that time dragon has gradually lowered its apog or the highest point in its orbit as the crew got ready for the space walk today they started to Dawn or put on their Eva suits just a little bit of time ago and they've been undergoing a process called pre-breathing where the atmospheric pressure inside dragon is slowly decreased and oxygen is increased to prepare their bodies for the Eva suit environment we're going to dive more into the operations of the spacewalk a little bit later and we're going to be hearing in live communications with the crew throughout so be sure to listen in as those happen yeah it's going to be super exciting to hear that and as far as views goes we'll have dragon's regular internal cameras that we have seen before and up to three external cameras one aimed at the hatch uh kind of like what you see there uh one on Dragon's nose cone uh which actually is the one that's there that's the the the camera on the nose cone and one on the newest piece of Hardware that you see there in that view we that is the Skywalker um which we will come back to shortly we may also have helmet cameras that will give us a firstperson view from the crew which will be incredible now since we are not using starlink to uh enable views today there will be moments of expected loss of signal due to ground station coverage so those views may be interrupted from time to time but generally we expect to get some great shots today and as of right now we're less than an hour away from the start of the Eva a for now though let's learn a little bit more about the mission and our crew the Polaris program is a first of its kind effort to rapidly Advance human space flight capabilities while continuing to raise funds and awareness for important causes down here on Earth today's goal is to demonstrate critical operational capabilities that are going to serve as those building blocks to help further human space exploration Play Dawn Mission has a lot of firsttime objectives so the players program chose a crew of experts who know each other so they can tackle this mission's challenges as a team first up Mission Commander Jared Rook isaacman also served as the commander of inspiration for the world's first all civilian mission to space Jared holds several world records including two speed around the world flights in 2008 and 2009 for the Make A Wish Foundation he has flown in over 100 air shows as part of the Black Diamond jet team dedicating every performance to charitable causes in 2011 Jared co-founded what would become the world's largest private Air Force dren International and that trains Pilots for the US armed forces in addition to his role as CEO of Shift 4 Jared is an accomplished pilot and astronaut with over 7,000 flight hours next up Mission pilot Scott kid potit who served as the mission director of inspiration 4 and he goes by the nickname kid which is also his call sign he's a retired US Air Force lieutenant Colonel kids served for 20 years in roles that included commander of the 64th aggressor Squadron Thunderbird number four demonstration pilot US Air Force weapon school graduate operational test and evaluation pilot and flight examiner he's a command pilot with over 3,200 flying hours logged over 400 hours of combat time and following his Air Force career kid served in various roles including vice president of strategy at Shift 4 Mission specialist Sarah Cooper Gillis is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew one missions and most recently directly trained the inspiration for astronauts Sarah is an experienced mission control operator who has supported real-time operations for Dragons cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for dragon's human space flight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program full-time and capping off the Polaris Dawn crew mission specialist and medical officer Anna Walker Menan who serves as a lead space operations engineer here at SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragon's crew capab abilities and develop critical operational responses to vehicle emergencies prior to SpaceX andna worked for seven years at Nasa as a biomedical flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going to space that's clear but let's take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isaacman I'm Scott kid potit I'm Sarah Gillis and I Anna Menan and we're the players Don crew I Love This Crew I mean all of them are just so hardworking so smart kid po over here is our mission pilot talk about a career in the Air Force doing every job as a pilot than than anyone would aspire to achieve and having somebody who has you know been there before and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always there glue glue you are always there predicting what every person means um and he's needy what our commander Jared I think he is incredibly sharp that's right something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical confidence we don't get out of any engineering update or brief or go through a procedure or debrief without getting into the weeds and making sure every tea is crossed every guy is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared that served her in her role as core it serves her in her role as a trainer Anna you have this incredible joy that you bring to everyday life it is infectious it makes us all smile feels like she always has this this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then as a biomedic engineer and background like that inspires like a ton of confidence that we go up there if uh people aren't feeling right that she's going to be there to take care of I cherish all the moments that we've had uh in these experiences and uh we're just so excited to to go to space now that you know a little more about the polar on crew let's recap the mission so far and what's coming up next since liftoff and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours demonstrating the Eva suit's pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I mentioned earlier on day two dragon proceeded to a high apogee of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the spacewalk dragon has been executing a series of Apper apogee low apogee lowering phasing Burns by now dragon has lowered itself from the highest apogee of the mission of more than 1400 km to about 190x 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude Children's Research Hospital um and they they're joined Live While polaron crew member Anna Menan read from her new book kisses from space along with the patients and families at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the Polaris daon crew Enlisted the help of Childhood cancer survivor Liv to create the missions Zerg indicator while not a St Jude patient herself Liv met the inspiration for crew and inspired by the mission of St Jude she agreed to share her talents to support pois stone is live and I spell it l and then an apostrophe Mar it's Park I can tell you anything about space from the miles from Earth to the Sun to every Mission basically I had cancer in 2021 cancer survivor like Haley I really have a passion for wanting to help St Jude and other kids who have those struggles as I had so I first met Liv a couple days after I got back from space at our Splashdown party and I got to meet her they told me about her journey that she was on I remember that she gave me a card she had written and it said thank you for helping other kids with cancer like me I hope to go to space like you someday and my eyes just filled with tears whenever I read that basically my one passion is to um be the first child in space Liv was really close with the players Don crew and they asked her to design the Zerg indicator a zerg indicator is like a little plush toy that floats in the air it basically shows that you're in zg they kind of hide it over in the corner and then once you hit zg it'll float up and reveal itself my main idea for asteroid is based on elon's dog py I I've always loved she buts they've always been really cute and then when I heard I was like done I love her I want asteroid to be for every child and help them see oh as went face and I can too I can achieve my [Music] dreams we are also flying Liv's original drawing that you see there that was used to design the Zerg indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital all donations from the sale of asteroid will will be General donations to St Jude the the inspiration 4 Mission helped raise more than $240 million for St Jude Children's Research Hospital and polaron will continue to raise funds and awareness for St Jude while partnering with the organization to provide Health Care in underserved communities around the world now if you want your very own asteroid they are available at shop. spacex.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the way so sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got like I snagged one I got in there I got a kid who nice needs one yeah all right now the first phase of The Space Walk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre-breathe process started that's when the oxygen levels started to increase incrementally as the actual the cabin pressure inside Dragon was stting to get incrementally lower the pre-bath process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any space walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure of in deep water back up to the surface and to do all this dragon's just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in in the suit during the spacewalk itself they've got the ability to pause the process if they experience any discomfort but the ear ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude on an airplane um all four astronauts are going to be suited for the spacewalk today because Dragon does not have an airlock that's also kind of why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with the stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah are just going to be lightly secured ahead of the spacewalk since they're going to be moving around and eventually heading outside as we listen into comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support to is Anna again they will not exit the dragon during the Eva but make no mistake they they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rotate those upright during the Eva just to give more room to move about after that seat rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tabs in the health of their suits and they'll get some other stats of their suit operation during The Space Walk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations brief from the SpaceX team the crew will announce their go noo status and then it'll be time for the spacewalk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the cruise suits until we complete the repressurization of the cabin and just prior to we get to cabin venting pure oxygen is going to start flowing into the cruise suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the sun this will help keep temperatures Communications and spacecraft power stable during The Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during The Space Walk he's going to be the first to exit the spacecraft he's going to go outside and he's going to do a series of Mobility tests these are kind of the core component of the spacewalk today he going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into Dragon after that ev2 or Sarah will step out into space to perform per the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit and then after she's completed her test Sarah will stand by near the hatch for the actual closing and then at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is suited up and awaiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the spacewalk and before we get there though we're going to expand the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back here in Hawthorne with you tonight on this uh very memorable night for sure yeah absolutely uh now Evas may be new to SpaceX but uh you have participated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two missions you know the first one was back in 2013 and I uh I went up on a Russian soy use and on that one we had two space walks and the interesting about those spacewalks is they weren't planned uh they were what yeah they were a big surprise for us uh contingency spacewalk and of course surprises happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a space walk as everybody was getting ready to celebrate Christmas just helping deliver presents that's right right that's right and then your first play was on the so but your second one you were the commander of crew one I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than anybody cuz you you actually got the call at home while you were docked up there that's right it I me I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was in a great amazing group of people not only uh uh Victor Shannon and suichi but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough creu stations and actually you can see a picture of uh of where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the station where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for crew one weren't they they were yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees yeah and somebody else getting to uh getting to test them all the time so uh yeah it was pretty neat to to get to see that switching it up a little bit because we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to, 1400 km uh we like to talk about something called the overview effect so kind of that first yeah that oh and we're getting some coms from our crew too yeah nice space Dragon radio check c l clear kid H me C you loud and clear dolphing continues unless so just going to be right Captain m c that kid make that Donnie all right some some quick com checks we heard kid that Scott po he's going to be one of the support crew in there today so our our first CS down as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back and I mean you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overview effect is definitely real but when I first got to space um on that on that soy use uh gosh how many years ago almost nine years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now this is really that's pretty but oh no um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you'll hear people talking about that that small sliver of atmosphere and you you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me a lot of questions and made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it brought as many questions as it did answers hopefully a bunch of bunch more trips then right that's right yeah that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank White originally coined the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habitable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different emotions that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moonrise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to Mars and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward W to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of space next support two's next and then ev1 and two are surely [Music] behind copy on that crew status getting a quick quick crew status from Kid OB yeah I I think I speak for a lot of space exors we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dragon and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean spacewalks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first Space Walk is contingency we had a failure and so sometimes when we're going outside it's it's not planned and you have a component that that is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out and we're putting in a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar rays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Dawn crew is going to do today and you're just checking out the suits and checking out the equipment that that you're going to use in future space walks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um SpaceX for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction requiredby actually uh if I can I'm just going to jump in on that that's actually a very important call was made you heard him say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around of what was that and so you heard them give them a warning that we're going to turn on some fans yeah and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those spacewalks where I was uh at you know outside and and what are you proud of you're you know it's it takes takes so much to put these vehicles up in the space and and so when you go out on the space walks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because uh people are depending on you and couple of people watching every your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good station's back up 100% just like okay that's that feels great Dragon Space X our fan commanding is now complete [Music] tell all right hopefully no surprise sounds in there for him so I mean space walks are something that you you train the heck out of they're they're playing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a space walk yeah so I mean one of the first challenges that you're always worried about is the how you're suits functioning right cuz that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground are monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between you and the and the ground and so they're making all of those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about spacewalks that uh maybe people don't realize is you know you focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they ex the these space walks um they they you you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk it no it never felt like a cakewalk at at all um you know it because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely um very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on you're more familiar maybe is a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I'll will equate a little bit of of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all of that kind of nervous energy as you're getting ready to go out well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on seat rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them upright that's just going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is spacex's 14th human space flight Mission since 2020 when Dragon became the first private space C to take humans to the International Space Station it's also the first private spacecraft to take an all civilian crew to orbit during the inspiration 4 Mission in 2021 and just prior to Polaris Dawn Dragon completed 46 launches 13 of those are human space flight missions and it's since flown 50 astronauts representing 14 different countries throughout all of those missions dragon has helped support more than 1,000 experiments in space pretty incredible that's there um and even from low earth orbit dragon is helping lay the groundwork for deep space exploration through missions like inspiration 4 and Polaris Dawn we are rapidly expanding our knowledge of how humans will adapt live and work in space designed to be the safest spacecraft ever flown the fully autonomous Dragon stands nearly 27 ft tall and 13 ft around dragon is capable of carrying up to seven passengers to and front Earth orbit and Beyond but today it's carrying the four members of the Polaris Dawn crew and the crew is currently living and working in the top portion of the spacecraft that's that white section that you see there also known as the pressurized section this allows for the transport of people and environmentally sensitive cargo below that dragon's trunk it sits right below the pressurized section that can carry unpressurized cargo on resupply missions and it remains attached to Dragon until shortly before re-entry into Earth's atmosphere and as you can see about half the trunk is covered in solar panels those provide Power to Dragon during the flight the other half is the radiator Dragon itself is equipped with 16 Draco thrusters we got really cool view of the four forward bulkhead ones firing earlier on this flight with lights on Earth behind you those are used to orient the spacecraft during the mission they also get used for apog and Pary raise and lower Maneuvers orbit adjustments and attitude control for the Eva the Draco are going to be used to reposition Dragon so the trunk is facing the Sun and they're also there to be used for reorientation during the spacewalk if needed in order to accommodate accommodate a spacewalk this is the first dragon to be outfitted with a Skywalker in place of the Koopa observation Dome the Skywalker that you see there looking up at it uh from the from basically from underneath it um the Skywalker is a structure that is mounted to the top of the Dragon capsule and the astronauts will use this to assist in exiting and re-entering the spacecraft during their space block the team also added additional nitrogen tanks to assist in repressurization of the capsule after the Eva another new feature on Dragon is the addition of a motor plus hand holds and footh holds inside the spacecraft to help with opening and closing the hatch during The Space Walk This Dragon also carrying what we are calling the starlink plug and pler making this the first Miss on Dragon to use the starlink network in orbit inside a dragon is a router connected to a user terminal in Dragon's trunk and then this terminal is linked to a new plug-and player device that's mounted nearby while we're not using starlink for continuous coverage during this operation we've been testing its ability to establish and maintain laser Communications with our starlink satellites there in orbit that are below dragon dragon has proved to be quite a versatile spacecraft it can autonomously dock to the space station when outfitted with the ISS docking adapter and when it's intended for free flyer mode the docking adap adapter can be swapped drag and you guys are walking come on back aboard if you want SP copies don't have uh ground station right now but we'll go ahead and bring cameras back on board so we get it when we do have ground stations quick comms there with SpaceX core uh from the Dragon capsule that was uh the crew just letting the folks here uh in Mission Control letting us know that it's okay to turn the onboard cameras back on once we have uh coverage for those cameras um but getting back to the different um configurations that we have for the Dragon capsule um I was talking about the docking adapter previously when the Dragon capsule is intended for free flyer mode docking adapter can be swapped out for a Cupa uh which is the one in the middle there and that is used for the best views that you can get while in orbit and then of course our newest option the Skywalker Hardware to support extra vehicular activities and that's what the crew is going to be using this morning so those are the current three ways that dragon can be configured to support different types of missions but hey you never know what's to come we always got something up Our Sleeve right now Mike crew one broke the record for the longest space flight by a us crude vehicle surpassed the 84-day mark that was set by an Apollo capsule during that final flight to the Skylab space station in 1974 what was it like cuz we we went over it you literally called Dragon home during that time what was it like to live in there so so first of all I got to say it's pretty exciting because uh the the dragon that they're using right now is the dragon that I lived in that took us to orbit uh yeah we affectionally called resilience uh and it was a it was an amazing spacecraft uh it it uh from a standpoint of living inside it and um again it it a lot of room actually compared to some of the other crew quarters that we had on board and uh and and plus just uh you know being able to to uh spend all that time in it you know I call my family every night before I go to bed and I'd be looking out the window uh at the Earth uh as as I was doing that it was uh very special did did any of them get jealous cuz you had the window seat well yeah there was a little bit of that certainly going on up there nice now as you mentioned this Dragon capsule that the inspiration excuse me that the Polaris Dawn crew is flying in was previously used uh really debuted on the crew One mission hence why you guys had the um honor of naming it in the first place but this capsule was also used for the inspiration for mission that uh Jared also commanded um what is your take on uh this being one spacecraft but supporting multiple missions I think it's fantastic it just shows the flexib of the design that SpaceX made when uh when looking at the crew Dragon vehicle so I I I think it's very exciting to see a vehicle that can that can go from one mission to the other and and quite frankly do it quite uh quickly as well I think I don't remember the exact timing uh from our mission and when we landed to win inspiration 4 launch but it wasn't a very long time and yet you were able to take that docking adapter off put the uh Koopa on in a in a very short time which is also pretty impressive I actually have that noted here uh crew one took off in November of 2020 and inspiration 4 lifted off in September of 2021 that's that's we landed in May of 21 and So within that short period of time you reconfigured the vehicle and uh and were able to put that coup lawn and launch yeah impressive your mission patch sticker is in the is in the capsule that they're in now and add their own sticker too as well right all right well as you can imagine dragon has undergone some changes for this and with changes comes extensive testing for the mission and all the modifications that we made in preparation for today had to go through kind of their own test regimen yeah testing is a critical part of qualifying a spacecraft like Dragon for flight rigorous testing helps identify and mitigate potential risks verify system and component reliability and helps ensure that the designs meet the mission requirements there are many types of tests a spacecraft might undergo when qualifying for flight including structural thermal vacuum radiation software and Integrated Systems testing one of the tests the new Skywalker Hardware under went is thermal vacuum testing this actually tested how Skywalker withstands the extreme temperature swings that it's going to see while it's in the vacuum of space and while Dragon was being put through all of its Paces the Polaris Dawn crew was going through the same SpaceX training uh as part of our that we give to NASA astronauts they also had a train to perform their Eva though for basic training at SpaceX Hawthorne they train on everything from orbital mechanics to just how to live and work in microgravity also ran through numerous simulations of what the full mission would look like while they were seated inside of our Dragon trainer in addition to ensuring that they're familiar with spacex's Falcon 9 rocket and dragon spacecraft the crew went through an extensive training regimen to build their physical endurance and mental toughness ensuring that they are well-rounded and prepared for space flight and today's Eva now switching gear is one of the coolest things designed in-house by SpaceX the Eva suit has all the functions of our original space suit with the added bonus of allowing astronauts to exit the spacecraft while in orbit and this Mission this Mission gives us a great opportunity to test our Eva suits in space building a base on the moon and a city on Mars will require thousands of space suits so the development of this suit and the Eva performed on this Mission will be important steps toward a scalable design for space suits on future long duration missions as we mentioned SpaceX designs and manufactures our own suits and we have a little behind the scenes look for you something most people don't get to see the inside of our very own suit lab an Eva suit is an extra vehicular activity suit which is a space suit that can go outside of the spacecraft to do a space walk we started with the Iva suit that we have the intra vehicular activity suit as a kind of starting point and looked at it and said what would we have to change about this to be able to support a space walk so the first is mobility um the crew will have to do a lot of moving around inside of dragon to get outside and do The Space Walk we had to add in new joints um and new features in the suit to allow them enhance Mobility while the suit's pressurized when the cre member is pressurized in the suit the soft portions of the suit become rigid they need actual and rotational joints to allow them to move around it's kind of like a suit of armor made of fabric we innovated in flexure joints to allow easy bending at the elbows and the knees as well as a collapsible Rotator joint that exists on the shoulder which allows the suit to remain nearly fully soft but when pressurized is a rotational bearing the difference between the Iva and Eva suit is that on the Iva suit the system location is in the inse uh but since we needed to have lots of Mobility on our Eva suit that was not the Preferred Choice by moving the sipper system from the in Steam to the waist we mitigated risk of the stress of the sipper and another big element was also the the thermal side of things the crew is obviously exposed to a much more extreme thermal environment during the Eva so we want to make sure that the inside of the suit is comfortable for them um and that as they interface with parts of the vehicle that that is safe for them to touch as well the EV suit is built and designed here at SpaceX in Halton California we wanted to have something that's easy manufactured that we can handle here in house so we developed this new material so it's fabric based we actually added a new layer to the suit uh which we refer to as the Faraday layer and this is a conductive cage around the suit that Shields the suit from external electric Fields the helmet on the Eva suit looks very similar to the Iva suit but is really an all new design of that helmet um it's much more robust from a thermal structural perspective since it will be taking more extreme temperatures we are really excited to introduce this new single pane visor helmet to the world of space suits the Eva suit visor is made of polycarbonate and is coated with copper and I or indium T oxide these two Coatings together reflect the Sun away from the crew as well as reflecting infrared heat back to the crew when they are facing deep space our suit has a HUD or heads up display which is a small display screen in the helmet which is transparent which allows the crew to see through the display to have unfettered access during their Eva but it also provides critical Telemetry to the crew so pressure temperature relative humidity we're trying to improve the technology and streamline it in one way and at the same time we're also trying to get it more and more manufacturable with each generation the ultimate goal is that you can put on a space suit and go out and get work done anywhere in the solar system um and not feel like you're wearing anything more than you normally wear every [Applause] day we also had a chance to talk to the SpaceX team that developed some of the hardware and procedures for our first Space Walk let's hear what they had to say EA stands for extra vehicular activity and it's any sort of operation in space where a human is getting out of the spacecraft so in the case of Polaris daon we're going to be testing the mobility of the suit we're going to see if the in space operation matches the training we've done here in Hawthorne there's really a lot of different things that can happen during an Eva and this is the first step for Dragon and SpaceX when I first started working at SpaceX I never thought I'd be training a crew to do an Eva it's brand new it's so unique we've never done anything like this before and so we wanted to make sure we had the best possible train program for this Mission we want to see if we can train a space walk on earth in a way that's representative of what it feels like in space even though only two people are going to be going outside during this first Eva all four crew will be in Eva suits going down to vacuum Dragon was always designed to vent to full vacuum but we've never taken full Dragon capsule down to vacuum and this will be the first time we do do it in space we actually put crew into a chamber at Johnson Space Center in Houston and had them live the exact profile that they will experience and making sure that no one actually experienced uh decompression [Music] sickness we have a couple new training assets for player St to train the Eva specifically the suspension system that we have is situated on top of the platform of our capsule Simulator the lines through the hatch they attach to a single crew member inside the capsule we can lift them up and get them situated so that they can ESS the capsule and perform their tasks at Skywalker the mobility Aid the Skywalker what's amazing to me is a lot of people are going to think it's a metallic structure just bolted to the top of dragon but a lot of development effort testing went into the Skywalker so we actually used similar technology as we have in the super Draco Chambers to apply a thermal coating to the outside of the Skywalker that is going to be a really really amazing Mobility gate on the front end of dragon we also developed a sideways simulator so we flip the hatch on its side in the event the hatch fails to close they can manually close the hatch we had them do that in a sideway suspension system so gry isn't helping them close or helping them open that hatch mechanism it's new development for Dragon it's new development for SpaceX and the industry as a whole so this is a great example of where polaron is forcing the team to innovate in a way that adds safety and reliability to every dragon mission going forward that's this huge challenge for us to go solve but that's also an opportunity for us to solve the problems that we have to go figure out anyway for our larger goals like putting people on Mars the poison objectives are the first step towards that ultimate flight with with humans inside of Starship which is right along the SpaceX development path that that we have towards getting to the Moon and Mars love seeing how not only the suit but the space operations for the Eva itself uh came together and were developed uh now we are still counting down to the spacewalk this morning uh the crew is or EXC me the crew on board is completing final fit-ups and we're going to be standing by for seat rotation and suit leak checks so we're continuing to truck along to the the the main event uh now Mike you obviously went through some of the suitup process that we saw in that package in terms of um the the development of the suit and how it's custom fitted for each individual and that's that's the same case for an Eva suit so maybe you can share with us what that experience was like yeah it it's extremely important uh to to have a suit that fits whether again it's the Iva the EV Eva suit or the Emu that we wear with NASA when we go out on the spacewalks and the reason for that is because if it doesn't fit right it can be extremely uncomfortable you can get what you call hot spots or uh there can be a a a place where the a crease when it gets pressurized can really put a a uh a hard point on your arm or something of that nature so having a good suit fit check is extremely important and and it's one of the things that was kind of fun as well because you get to spend a lot of time with the the suit team here with Chris and Eric and Mar they're fantastic and and I mean just over the years they've gained so much experience and they can really help you hone in on what a the really good fitting suit is is like with just the way they ask the questions and lead you through that that process wow what are what are kind of The Sensational differences from being in like the Iva suit because a lot of times the Iva suit when it gets pressurized you know it fills up but you're still in like a pressured environment with Eva suit you're in the vacuum right and so like what's it kind of like yeah so you know that Iva suit it has a different purpose right and that the purpose of that Iva suit is to Keep Us Alive in the event of some type of an emergency that might happen during a launch or a landing and and so that's that case where either you have a fire or you have a depress event and so that suit's going to pressurize and so in that case we're not as worried about like the mobility of of the suit you just want to get home and and do it in a safe way and so you need to have enough Mobility to still be able to control the spacecraft and and do do the things you need to do but but you're just not as worried about it because you're not trying to perform a maintenance activity or or something like that when you're going down on the on a on a spacewalk and and so I think that's that's one of the the biggest differences between the Iva suit and the Eva suit is just what the purpose of it is and what you're trying to do with it yeah that feedback loop um is so important to be able to communicate what feels good what doesn't um because I imagine um you know as you're out there and having to perform you know as you mentioned maintenance activities uh among other things that the functionality of your body is critical to to to perform those it really is and probably one of the hardest I think parts of the suit to design is the gloves right because absolutely you know you hear us use the term it fits like a glove right we use that a lot but but you don't realize how much you use your hands when you're outside on a space walk as opposed to say your feet when you're you know cuz in space we don't use our feet our legs as much as we do our hands and and so when you're in a a pressurized suit like that and you're constantly grabbing and reaching you are overcoming the pressure of the suit and your hands can get just exhausted and you can get those hotpots um I had some issues with my emu gloves when I first started training at Nasa and I would actually get uh what's called delamination on my fingernails yeah and and so there's just little things like that that it really matters how well that suit fits and and how well it functions and and so uh it you don't realize how important that is sometimes yeah um now we are going to be stepping into suit leak checks soon um can you share with us a little bit about what that process uh entails um and and and more importantly because you you've actually experienced what it feels like to go through suit leag checks what what that experiences like extremely important part of the whole process right because before you take the C in this case all the way down to vacuum you want to make sure that your suit is maintaining the pressure that it needs to and and so it's a it it's a not a very long process it's usually just you know a few minutes to two or three minutes um and you know the the interesting part is if you don't pass that lead check what do you do next and and so there's always usually procedures associated with that as well that start checking your zipper start checking how you've closed things up did you not get something sealed quite right um and and so it's always a good point in the mission when uh whether it's on the Launchpad getting ready whether it's in the airlock getting ready to go out the door when you when you hear that yeah good leak check uh because now you know that you're ready to go so today's going to be kind of unique because all four of our crew members are going to be like doing The Space Walk they're all going to be exposed to the vacuum of space but I mean even when you did space walks it's never a solo act right like you're always out there with a partner you you are it's uh it's extremely important in fact one of the hardest parts about our training for space walks is what we call incapacitated crew and so you need to always be able to get your crewmate back into the airlock if something should happen if uh if they should no longer be conscious and and something of that nature and so we we actually do spend quite a bit of time and that's why it's extremely important for us to go out in pairs because things can go wrong um and and so you want to be prepared for those those moments yeah U that's a great Point Dan to make that um while only Jared and Sarah are going to be somewhat exiting the spacecraft um all four crew members are going to be exposed to the vacuum of space and it's actually going to set a new record for most number of people exposed to uh or not them without a suit but like yeah in the vacuum of gravity all at the same time yeah that's actually interesting I never I never actually thought of that piece of this Mission and the fact that you're going to have four people on a spacewalk I I know at one point on a shuttle mission we had three y three folks outside on a on a spacewalk u and so yeah that's a that's a big deal and and kind of exciting you know one of the one of the things we do on the on the space station of course is We Have astronauts that are still inside and if we do get into those emergency situations they're there prepared to help us uh get back into the airlock and and uh and get unsuited and and things of that nature so of course when you have all the crew it just makes you think about those emergency situations probably in a little bit different way than we than we do on station yeah and hey if you're just tuning in we are still waiting to really kick off our spacewalk today so right now the crew is inside the spacecraft they're getting suited up we should be hearing some CS from them pretty soon and then X Dragon um ev1 is completing glove zipper closure but at this time we are ready for seat rotation copy that for seat rotation can you confirm crew is ready with the current glov zip props all right I I guess they just needed me to to say it was coming soon and then and then there it is uh but uh we are going to hear the seat rotation coming up soon again they're in their recline position and I'll do stand by get the M seat copy standing by so they're going to get those seats rotated and then we're then we're pretty much going to be ready to start getting into things and uh our Eva is going to officially start when we start flowing O2 into those suits um and so that'll kind of start our clock we're going to be showing you some of the Telemetry so all those numbers the bottom of your screen you've got a couple right now uh that one all the way in the bottom left corner that's your Dragon that's your dragon cabin pressure that's in PSI ready for location space copies initiating seat rotation great news there that's going to help give the crew a little bit more room to move around uh during The Space Walk and after we get through the seat rotation we'll be able to perform those suit leak checks that we were just talking about yeah before they do that they'll do what's called a tear so it's kind of like if you're ever using a scale you zero out the scale before you put something on it it's essentially what we're doing with the suits they'll get like a baseline reading and then as we start to actually pressurize the suits we'll be able to measure that against the Baseline make sure everybody's got basically a nice seal before we start that vent yeah that one's pretty important that was pretty important yeah um so a lot of that's coming up again some of the data on your screen you've got cabin pressure you've got suit pressure Dragon Space X seat rotation complete and nominal all right seat rotations complete so now they're going to start doing that tear getting ready and can I get a confirmation of completion per the call out in 2 decimal 18 complete with copy at this time you are go to step into section three and tear suit deers now just a quick reminder in case if you missed the top of um the show we're we're going to be referring to the crew a little differently for the Eva activity um than we were previously so we heard Anna uh talk ev1 that was referring to Jared so his basically his call sign for this uh spacewalk operation is ev1 um Sarah's call sign will be ev2 Anna will be support two and uh Scott will be support one uh also Scott and Sarah are switching seats uh I perhaps they already have cop you stand by for HUD power for pressure sensor checkouts okay so our suit tear completed so next up is going to be the HUD checkout so the HUD your heads up like real quick we do have on your screen though that's your seed order so uh you've got ev1 Jared is in that seat he's going to be in that seat right now but once we actually get ready to open the hatch and everything he's going to be positioned kind of over by the hatch and then Sarah ev2 is going to be in one of those Center seats then you'll have Anna and kid on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks in 3 decimal 2 so and that's our that's our SE layout we just heard the Huds are powered on so they've got heads up displays actually being kind of projected on their visor in their helmet which if you if you've ever seen space suits that's always kind of felt like that's that Space Age Technology that were missing cuz Mike you guys use kind of a a a simpler but a little unorthodox way to see like your suit data yeah that that's right then it's uh of course this the suits and they that t check out complete on nice copy swapping the backup sensors standby to repeat H checks so of course the suits that we use for the the spacewalks on station are a little bit older they've been around for for quite a while and and so some of this uh technology uh you know look it's our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chilling yeah so there out of his seat that's Commander Jared uh who like I mentioned before will be referred to as ev1 behind him we can see already in his new seat uh pilot Scott kid potit uh he will be support one and then moving around in front of us is Sarah who will be ev2 and then just out of view underneath the camera but I think you can see her visor is um Anna Menan who is support to Dragon SpaceX we're on backup sensors repeat Hut checks the crew is going to check out those heads up displays one more time real quick check back copy good Huds returning to primary standby for helmet camera checkouts on that heads up display they'll be able to see the O2 flow timer that's kind of like our mission clock essentially like once the O2 has started to flow to their seats and they know they've got about an hour and 50 minutes just under two hours for the whole time uh they'll be able to see their suit pressure temperature basically it's a way to kind of keep an eye on things and we were talking about a little bit Mike but on the Emu is a little bit different yeah the Emu is certainly different uh a lot of that kind of information is on a on a display right in front of you that you have to kind of look down to see and it it can be pretty challenging to see in fact a lot of the information you have to use a mirror on your wrist uh to be able to to read it and know what you're what you're controlling as well uh you mentioned the timer of course we don't have that kind of information on on ours and I'm not sure I'd want to know that cuz i' feel the pressure of I got to get a lot of things done I'm running out of time yeah all right um so they're they're going through these HUD checkouts again pretty soon Dragon Space X powering on helmet camps we're going to get the helmet cams powered on again give you that kind of look right over their shoulders yeah pretty excited for these we've uh seen them utilized during the training uh sessions that crew has undergone and we're so excited to to see them live today yeah I I tell you the helmet cameras I mean it's going to be fantastic views right that we're all going to love but but there's also a very important um role for those cameras as well like when we have the same thing we have helmet cameras with the emus and what it allows is your ground team Dragon SpaceX suit cameras powered confirm good health so it really allows your ground teams to to kind of be able to see what you're doing and video and almost double check your work copy checkouts complete Huds will remain powered proceed to step three decimal three operations review through three decimal 8 report one complete all right so we got through HUD checks we got cameras on powered ready to go so right now the crew is going to go through they're going to do kind of a final review of all of their procedures like you talked about this a little bit like these things are so choreographed because even if you couldn't see the clock like you're on the clock so you've got to you've really got to make the most out of like every single second you're doing one of these you do and and of course you see that with with today's space walk as well space X repeating checkouts are complete Huds are going to remain powered proceed to step three decimal 3 operations review through 3 decimal 8 and Report when complete not the and and the reason it's so choreographed and important is because you only have so much time outside right you only have so many consumables that allow you to go out there and so you want to take advantage of all of that and you want to have every step very well scripted so that so that there's not a lot of wasted time now that being said it is nice when you're out there once in a while to just kind of take a moment look around enjoy the views kind of try to absorb where you actually are which uh can be pretty incredible as well every every once in a while guys I'm a little tired I'm gonna take a minute that's right I need to take I see my house from here that's right yeah right but like it's it's awesome we're seeing the crew inside we're getting close to the start of today's Space Walk we're going to start flowing O2 to the suits and that's when our clock's going to start right now they're just doing kind of final cabin configurations they're going to check the lighting uh they're going to make sure that their umbilicals are in the right spot that's one of the things you'll see that's actually one of the the the roles that our support uh crew members are really going to that's kind of one of their one of their primary jobs during the spacewalk is to manage those umbilicals for you guys Mike you had one that's uh what plugs into the leg in your suit and that's what's providing like the breathing gas coms connections all of that stuff uh for the spacewalk today it's a little bit different this one uh that uh they're going to be using has some tethers in it um for Anna or for Sarah and um Jared it's about 12 feet long so it's like about double double the length of what you guys have so so it's Dual Purpose right it's it's providing them the the air and the cooling that they need while they're out on The Space Walk uh but it's also providing that safety piece right so that if uh if something should happen they should slip or um that that they're not going to go floating off into space with the Emu uh that we use on the space station we actually you know all of those consumables are a part of the suit itself and we have a separate safety tether that the first thing we do when we open that hatch and we go out is is we hook up that safety tether and it's an 855 ft reel that uh as you're moving around it it goes out with you to again protect for that crazy moment when maybe uh an emergency happens and you come off station how how hard was it to manage all of those tethers I feel like every time I watch it like there's no way in heck that this thing isn't getting snagged on something no you're absolutely right because everything and and you talked earlier about making sure there was no loose items in the cockpit right CU when you open that that hatch uh things are going to want to float away if they're not tied down or stored or anything like that so when we go out on a Space Walk not only do we keep us Tethered to the spacecraft but any tool any part that we take out with us also has to be tethered and it can be quite a challenge to manage all you'll open up a bag and there's there's 10 pieces of Hardware in there with 10 different tethers and they get all tangled up and and it can really be pretty challenging it's important though um we simplified that a little bit for this Mission um we actually basically built in that tether into the umbilical one of which you can see actually they're floating uh under Jared's right arm so not only does that Pro provide airf flow and comms and uh all the normal connections that we have in the in the umbilicals but we also added that that strength uh to provide that protection yeah and and the managing of that tether is extremely important because you know as they go out if it can get tangled up and you actually see Sarah there kind of moving around right it's it's very easy in in this environment where you're floating BX Dragon Eva off you complete who are in position to Eva start nice exop Cent position but you saw Sarah kind of move the tether out of the way and the part of that is that's actually impacting you go to command box push a talk all seats C and so this will this will be one of the unique things about the space walk today it'll it'll feel familiar if you've ever if you watched some of Mike space walks the crew is going to go over to what's called V set go come check ev1 come Che ev2 com check support one com check support two com check SpaceX copies all good coms all four crew all [Music] so essentially now all of our crew are on open mics they can all talk and hear each other and they can talk to the ground and so you're going to hear a lot more chatter start to pick up uh once we start the suit pressurization you're going to hear almost like a sound that's just the air starting to flow into their suits um how how loud does it get inside your suit it it actually is quite loud that air flow is just constantly which is a good thing right because not only is it providing you the oxygen but it's also helping get rid of that CO2 that you're breathing out so you want that air flow uh to be constantly going and and so you always are hearing that van uh that that's uh making that happen and so that is that is certainly pretty important and the Vox thing I got to say you know it's nice that you don't have to push a button when you're outside there to to talk Dragon SpaceX we about 90 seconds from E initiation got some fist bumps going on yeah and we just heard we about 90 seconds from Eva initiation so we should see them get the go to close their visors and then they're going to open up one of the O2 valves on their suits to start the suit Purge and that's going to be the official start of our spacewalk today so we're we'll get through the the final goes and then we'll see those visors get closed oxygen start flowing and we'll be off I love how everyone looks so calm and collected right now I think that's a a a great visualization of just all the extensive training that they've gone through to get to this point this has been years in the making um I'm sure they're excited uh but everyone's focused it it it is an interesting time right now right because one of the hardest parts I always found about dragon SpaceX SpaceX is go for Space Walk operations report visor is down ready for secondary O2 flow initiation and crew is go for space verify your visors are [Music] closed secondary O2 B is open [Music] and that you are go for the EVS ev1 is go ev2 is go support one is go support two is go [Music] Dragon Space X initiating secondary [Music] O2 and with that news our Eva has [Music] begun so you're you're going to hear referred to as primary and secondary O2 primary is going to be that primary flow of oxygen to pressurize secondary is largely putting oxygen into their suits to help with cooling but second there is the first one we turn on and so our O2 flow timer has started Eva start at 3:12 a.m. Pacific I'll do the math on UTC in a little bit so this first this first operation or this first step in the operation is a suit Purge so inside their suit obviously when the visor is still open it's still a nitrox environment it's the same as the cabin uh and since they're going to be at a lower pressure than what you can basically live at with with oxygen levels um they're going to be on pure O2 they're going to be a 100% oxygen environment and I mean you guys were kind of in the same thing and it's it's because like your suit can't you can't move a suit around at 14.7 PSI can you maybe you can like no that would be pretty that'd be pretty tough to do and and as we talked about earlier that's why that Mobility is so important because when that suit is pressurized like that it it can be challenging to move around absolutely so here on your screen we can see the polaron crew now with their visors down the Eva has begun we are beginning to flow that uh O2 through now we will of course bring these views to you as we have them but due to ground station coverage they do come in and out here and there um but every moment that we can we will certainly be sharing these with you um I also wanted to point out quickly that the the the window near kids feet was so much brighter than it was was uh just even 5 minutes ago we're going to be seeing that uh in start contrast as soon as we get uh the Eva with the hatch open and ev1 out there yeah it's kind of interesting you you you mention that because as you're going around the earth as fast as you are right in in 30 minutes or 45 minutes or so you can be passing in and out of that sun and and going into Shadow and and so that brings its challenges as as well because the temperature um can change pretty drastic ically just in those transitions from night to to Daylight and and so there's a there's a it's an interesting moment when you're passing through uh through that time that's actually one of uh the reasons that the visors have this new coating on them different than when you wore the a similar helmet um that coating actually helps to insulate the individual inside the suit so when they're looking at the sun dragon Space X a reminder after the initiation of primary O2 two flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow [Music] initiation ev1 copies ev2 copies Dragon SpaceX secondary flow Purge complete close secondary O2 Valves and Report ready for suit pressurization [Music] ev1 closed ev2 closed report one closed report two closed BX dragon is ready for SE pressurization initiating primary [Music] O2 this is normal this is with the airf flow coming through uh the crew members on Vox meaning uh that their their microphone is on the whole time so Sarah and Jared are going to be adjusting their audio levels um as this flow continues to to help regulate that yeah the the the voxel kind of attenuates so it'll it'll sound like this now but as we get through The Space Walk it'll kind of come down and you'll just hear voices a little bit more clearly uh there their voices are actually going to change too like did that did that happen to you did that throw you Mike the first time you heard that it absolutely did yeah cuz you're you're you're talking and you're going who is that right you don't realize how how much different it can sound um your voice can sound in that lower pressure environment yeah speaking of lower pressure we can uh we can see the pressure changing there with the Telemetry in the bottom left hand side of the screen so we can see that suit pressure going up um and we're able to keep tabs there um as well with the dragon pressure so Dragon uh on the far left Circle that's the pressure within the cabin and then suit obviously that's the pressure within the suit so we'll be actually be able to and I think we've kind of been able to see it already um that these suits will inflate a little bit um look a little different and we were talking about the the visors before so when they're in the sunlight that coating will help keep them cool and not overheat them and then when they're in Shadow it'll help keep them warm so uh and it's also like your sunglasses as well right serves that purpose all right so at this moment the suits are getting their primary pressurization this takes about 3 and A2 minutes a little bit less and then we're going to go through those actual suit leak checks I the crew will probably get a reminder they have to stay really still when we do those leak checks and I always was kind of wondering like why the heck and like if you if you bend your arms you're actually going to start you know changing the volume inside the suit that'll cause pressure spikes and so that's right got to stay really still yep and then after after we get through the Lea checks we're going to go through kind of that final pre-breathe uh where they're going to hang out in that 100% O2 environment just to continue purging all of that excess nitrogen um per complete ACC secondary FL on rep Portland complete E1 open or one open [Applause] dring and right there they they finished the purge and they did a quick uh reinitiation of that secondary flow check resp secondary flow and P complete if you want to call your support one St t turn second CL these handles that we see Jared holding on to these were one of the additions uh or uh customizations for this mission that we talked about earlier support one facex cont we got you all right copy got the Dragon space effect beginning c check evaluation and then still check so once again that background noise is expected um that is the microphones and and the flow of air uh within the suits so we're trying to stay quiet to uh along with you listen in on what the crew coms uh are as they go through um we're also uh going to get views in and out as we mentioned before due to uh ground station coverage continuing prev and it is it is a little bit tough to hear we just heard though that we got four good leak checks on their suits and now they're going to be in this final suited pre so again this is going to last about 19 or so minutes uh and this is just to do kind of that final get all of the excess nitrogen out um and we started pre breed just two two hours after they got on orbit just like you know gradually lowering the pressure and I mean preb that that's something that kind of evolved over time with the space station where where were we when you were doing your space walk yeah so we were past the kind of the camp out phase of free breathe um that's how we used to do it and it's very similar to what what the polaron crew has been doing over the last couple of days we'd actually have uh astronauts stay inside the crew lock overnight at a lower pressure just like they did when they first got on orbit now we've moved on to we do it the day of it still is a long day we start about 6 hours prior to going out the door uh but it's not 2 days prior it's worth noting uh along the lines of training and how the crew prepared for this mission that all four of our polaron crew members uh and some additional Polaris and SpaceX crew members actually went into um a a vacuum chamber and tested these suits out and spent uh a bit of time at lower pressure just to help learn what that feels like and get used to it well and I think the other thing that's important about that is it's real right it's it's the first time that you're in that suit and it's actually a vacuum around you right and there's just something mentally that I think is important to put people through those moments before you actually have to experience the first time in space yep we we saw some of the unique ways we train the crew for this and I mean training for space station space walks I'm still really upset I never got in the pool that looks like the coolest like parts of being an astronaut is like not being in space but just doing some of this training yeah Dan I I I tell you I can still remember the first time I stuck my head underwater not in the in the soup but in the for diving but you can hear the calms of of everything that's going on through the water like that and it just gives me goosebumps to think about think about that it was a really neat environment but it looks like these guys had a pretty neat way to train as well with the uh the the harness that would hoist them up and out and and all of that that's that's pretty impressive yeah um we definitely created some rigorous uh new training for the best we could simulate an Eva while still on Earth um with hoists and uh you know it was um it was a lot of fun to watch them train we'll be back on board with cameras in 3 minutes so our core just called out we'll get we'll get views back on board in about 3 minutes as Kate talked about earlier we're using ground stations for our video coverage all of our communication with the astronauts are through tedris so tracking a data relay satellites so we [Music] haveit we'll have constant audio but that video we need those ground stations uh but right now they're just they're in that pre-breathe uh that final pre-breathe still we started our space walk about 13 minutes ago when we initiated O2 flow to the suits the time was 3:12 a.m. Pacific 12 1012 UTC I did some quick map took me took me 13 minutes to do it but I did it um so we're once they're through this pre-bath we're going to start getting into some really exciting parts of the Space Walk and and then after after we get to the pre-breathe we're going to get to cabin vent so you know what's what's going through your head when you're like man it's happening the A's going out it's really happening it's happening yeah I I I tell you it is a long process to get to this point right they've been prepping for this for two days right and and one of the hardest things I found about the space walks is the waiting hurry up and wait hurry up and wait right you are so ready to to go out and to do this Mission and and to go out that hatch and it just takes time and I think that's one of the things you talked about my fifth versus my first your fifth you kind of understand how long it's going to take you have a better appreciation for how long it's going to take and so you literally find yourself in these moments when when you're kind of waiting through this pre-breathe or you're waiting for the airlock to depressurise just kind of find yourself just floating there kind of zoning out trying to keep yourself calm and relaxed and and until that moment when it's it's game it's game time yeah now just a quick mention we about a minute out until we uh get those views back uh inside the cabin um The View that we had previously was our Dragon tracker which uh if you want to see where Dragon is you can actually look that up as well um we have it on our website spacex.com follow dasdragon um but yeah just as a reminder uh our our crew they are in their designated or well Jared's not but um the yeah um are our crew members basically Sarah and kid have switched their seats for the Eva um we saw we last time we were able to see inside the cabin we saw Jared awaiting um to open the hatch so he wasn't in his Commander seat but uh Sarah is now sitting in Scott's pilot seat also known as seat 3 um and then Anna is on the far left side and Scott is on the oh yeah we can see it there on the far on the far right side um and also just a reminder uh their their call signs for these Eva operations um Anna being support two kid being support one and then Sarah being ev2 and Jared ev1 representing uh that Jared will exit first uh do his activities which include just some Mobility testing of the suit uh and then Sarah will go out and perform the exact same uh testing once Jared comes in um meanwhile uh kid and Anna will function as the eyes and ears uh they will be performing uh their own uh list of operations during uh or their own list of tasks during the Eva so while Sarah and Jared are going to be the ones that are you know partially egressing the capsule once that uh forward uh door is open uh kid and uh Anna will also be performing an Eva in their own right that's right and we talked about it earlier first time four people exposed to the vacuum of space like that's there's a lot of first in this that's going to be a really cool first not just for us and dragon um but we are going to be getting views back really soon we're again just in that final pre-breathe step right now and then we're going to start venting uh venting Dragon down to near vacuum so we're going to have a couple of different valves that are going to open up and the atmosphere inside dragon is going to start going overboard out into the vacuum of space now the crew the ground they can control they can pause that cabin venting if they need to uh we can pause and resume the most likely reason is for ear Equalization is again you're you're going through a lot of pressure changes anytime you do a space walk and so if you've ever flown on an airplane and your ears popped you've experienced just a little bit of what they might be going through right now uh once we start cabin venting if we terminate or abort that the spacewalk during that venting we cannot start again we talked a little bit earlier about how consumables are like the thing that really drives you uh and for us we don't have a great big airlock with this with you know a full station worth of oxygen and stuff like that um [Music] so1 go 14 copy initiating Caron venting there we go that is great news exting so uh that breathing of incre a pre-breathe where they were breathing increased oxygen we just heard that uh they're good they all all four crew members gave the go uh so now we're going to vent the cabin yeah in in total this will take in total this will take about eight8 minutes and you can this the graphics you see in your screen that's live Telemetry everybody so you can see the pressure inside Dragon starting to tick down you're going to see the sup pressure tick down as well is what we're really trying to maintain is a pressure differential and so with these suits we're going to be hovering right around five or so you might see about 4.9 to 5.1 5.2 um it'll be about 4.9 and then we'll probably see it go up a little bit uh when they reinitiate the secondary flow at and and you talked about that about five PSIs what the suit will be we're actually a little bit lower in the Emu and so we've talked a lot thought about Mobility that difference between we're at 4.2 and they're going to be at five it can actually make quite a bit of difference just in how hard it can be to move the suit around Etc yeah this crew got to and that's something we can simulate you know on in a vacuum chamber or even just uh in 14.7 you can you can simulate that that differential pressure getting call from the crew they're they're monitoring along 81 P 8 we're going to hear that kind of we're going to hear that chorus pretty frequently where you do those kind of frequent most like check-ins and I know you guys did something kind of similar where like you wouldd have to pause and you know check your gloves that kind of stuff we we did I I will tell you one of the interesting things watching this uh live right now the difference is how quickly the depressurization is happening here versus uh what my experience was and and so you talked about being able to clear your ears and all that you're not giving a lot of time for your you're not giving a lot of time for your your ears to adapt to that lower pressure so this this is seems pretty quick to me yeah break breaking new ground with this new suits new operations for everything we're at about 4.5 we're going to see that tick down it's going to get down to just under one and it's not going to go all the way down um and then what we'll actually see is we've got a capability to open the hatch automatically we've got a motor in it um but Jared's actually going to unlatch it and he's going to give it a little tug to kind of break the seal break any of the kind of the stion in the hatch itself and that's going to kind of take the capsule down to its final vent before Sarah who's at the displays she's going to command the hatch to actually open um yeah that's a good point and you know there's there will be slightly more pressure inside the capsule so really just helping four PSI two pressures look good copy four so Jared really can't open the hatch all in one fluid motion so we will see him uh release that that pressure slightly um before being able to open it completely and I think one of the important things you guys I think had talked earlier about you put some more um restraint devices inside the capsule from when I flew on it and that's extremely important because there's going to be some force that Jared's going to have to be pulling down on and he needs to be able to Anchor his feet somehow um otherwise he's going to pull and it's not going to go anywhere and so the the new restraint devices in there we're going to see how important that's going to become here when he tries to open that hatch yeah yeah that's that's one of the things that's why we have Skywalker out there we've we've talked about how kind of similar to to Gemini when they were first kind of stressing their legs but important to remember we've got that 50 or 60 years of space flight history that we're able to draw these are new suits this is a new operation this is to you know work out all the Kinks and really test us for the first time but we're going into this with a whole lot more information than they had back then we know you need hand rails it's going to get real hard real quick that's right that's right yep uh we did we did also hear uh dragon's moving into its uh its Eva orientation essentially we're going to point the trunk at the sun under 3 PSI I think it's also interesting you notice that the de pressurization has slowed down a little bit right so as we get to this lower pressure it's it's just taking it longer for that remain little bit of air to to uh go out through the vents and ev1 come Che E1 clear M clear as well also hear the Vox starting to adjust its levels that that flow of oxygen has not stopped but the microphone's kind of adjusted and it's getting a little bit clearer and yeah keep keep an ear out you might hear their voices start to like tener down a little bit I do think that's a an important Point Dan that how important Comm is yeah right and and when it's compromised a little bit just by that extra air flow and the Vox not keeping up with it right away uh how challenging it was just to hear those calls and they can be some pretty important calls so uh Comm is is just critical we can see Dragon capsule now approaching close to 2 psia like Dan mentioned earlier that's going to get to just under one it's incredible to think that uh you know the Dragon capsule in all of its power and glory and awesomeness the the new capsule is around their bodies right that that is what is going to protect them um from the vacuum of space and uh you know just seeing how even though it's puffed up and and we know that it's uh you know holding that pressure it still looks so cool for lack of a better [Music] word yeah you really have four Mini Spa or spaceships in there pressing PSI I guess that means we have four aliens in there too that's right Dragon Space X that's the one PSI from hatch operating pressure we have a tedious Handover in 2 minutes we are going to wait until after the teacher hand over to command in Hatch open [Music] prep one copy yeah I think you heard that the the te Handover so there's going to be a a short period of time there where they're out of Comm and we're at it's kind of interesting because we're at a very critical phase ah as well and so you want to make sure you have all the data and uh and the ability to talk to the astronauts before you actually take that next critical step we'll see it we we're seeing that pressure continue to tick down Dragon originally designed to be able to still operate in a vacuum that was some of the emergency situations I know you trained for Mike we did make some modifications to this one uh to essentially turn Dragon into a functional airlock um we added some additional uh vent paths um we do use like some of the same ones that you guys Ed to like pressurize the vestule and stuff like that um that are actually in the hatch but we've got a we've got an extra one in there to to be able to essentially do that deess as quickly as we did uh but we're going to we're going to see that get down to a little under one and then we're going to see Jared kind of jump into action he's going to unlatch the hatch and then he's going to give it a little pull to break the initial stion and then we're going to be able to uh see sarah. psia all SS look good one C that's one thing to note that while we have been progressing through this pretty quickly we did have the capability to pause if any of the four crew members needed to uh you know take a moment to you know let their ears um come to equilibrium or just kind of get comfortable again um we did have that option but everything has been going really well so far we haven't had uh to to pause cabin venting and if you're just tuning in heck of a time to do it we're about a little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of these crew members that was at 312 Pacific 1012 UTC we did heard that dragon's now in its Eva attitude complete so again we've got we've got dragon's trunk pointing towards the sun on board watching through the cross [Music] view that was SpaceX core Arthur baralt just letting the crew know uh that we're the cameras are on inside and uh basically which camera is is looking at them it's it's so fun to hear Arthur's voice because he was actually a part of our mission as well in fact Arthur was an intern started out as an intern when we were first uh starting the training and and so now to see him as a as a core and uh it it was pretty neat very similar to Sarah who also started as an intern yes yeah [Music] right we're coming up on one PSI you might see you saw the light change a little bit through that window is we're in our Eva position trunk facing the sun that's going to help us with thermal uh inside the capsule on the cruise suits also going to make sure we're maintaining that uh that optimal pointing for communications with the Tous satellites uh once the hatch is open we're going to disable any of the Draco thrusters that point forward is you know want thrusters firing off when a crew memb [Music] outside we're at one you can see the Su pressure is Tick down too there's about 4.7 difference between the suit uh and the ambient cabin there in dragon that umbilical that you see there uh just to the side of Jared that will continue to flow the air into his suit as well as provide Telemetry and Communications connection that's also where we have the um safety harness built in as well so it's able to Dragon SpaceX C pressure below hatch operating limit standby for transition to hasch open prep here we go Mike did you get to open the hatch I did you did yes yeah when you when you go out as uh G hatch open front Dragon SpaceX or E hatch open prep confirm CR to open [Music] hatch that is great open you keep [Music] SpaceX copies Dragon you are go to open hatch go excited SpaceX go to open the hatch Mike as you mentioned before that continuous communication hand as you can hear we do have a crowd Gathering outside of Mission Control uh here in hawthor in their excitement somebody dropped a cup we can see our commander Jared isaacman now turning the crank which allows the uh that top hatch to open we'll see him give it uh a pretty heavy pd1 hatches visually indicated open [Music] space copies stand [Music] by should see him give that hatch a pretty strong jolt to release that [Music] stion hatch is now unlatched [Music] Mike talked about we see him getting his feet getting his feet set that's right Dan You' ask if I got opene in the hatch so when you go out a zv1 just like Jared here is zv1 that's that's typically the role for for you is to open that hatch and guys have to draw straws whatever it's exciting it is it's very exciting yeah now for those of you that have just recently joined as you can see we have successfully depressurized the Dragon capsule uh down to Zer psia you see that in the bottom left hand side bottom left corner of your screen um are four Polaris on crew members um have uh gone through the uh O2 flow and and we see Commander Jared um isaacman now standing by uh to open that top hatch the nose cone is already open it opened just shortly after uh the crew got into orbit uh so Dragon Space X Target pressure [Music] reached bace X I'm oning the hatch [Music] now Jared now opening drag [Music] resilience into space so we saw some motion on the hatch again he's just given it kind of that initial tug and then Sarah gets to push the button to swing that hatch [Music] open much more movement there on the forward hatch [Music] this must be pretty exciting for Jared because that center part of dragon Space six that's a good brace we're going to have you repeat the operation center of the hatch actually has a window X the hatch is unse copy give it another call hatch is several [Music] in copy we see it [Music] looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes Dragon space xent [Music] complete ev1 return to [Music] seat and ev1 copy transitioning back under the [Music] display so again one of the reasons we had Jared do that was to [Music] Dragon SpaceX we're actually watching that hatch we're going to have you repeat the last operation sounds like they're going to have repeat them one of the reasons we're doing that is just to kind of vent any of that residual atmosphere and ev1 you are go for manual hatch [Music] open sounds like we got our first audible of the day as we said that we can open the hatch opening the hatch we could open the hatch man we could open the hatch automatically or we can do it manually and so they just gave Jared the go to open that hatch manually so we we just went out of ground station reach so we'll get the views back [Music] W we'll get the views back real shortly uh and then the the hatch see hatch open and hopefully we see it yeah hopefully we see a hatch open the hatch is open space X copies hatch open that is fantastic news uh for those that1 I'm looking at the heeld initial view looks pretty good don't see any VES oration copy on Hatch [Music] report yeah that seal that you just heard him talking about it's such a important part for the end of the Eva right so that when they close that hatch again you get a good get a good seal ev2 SpaceX can you command open forward hat because we're going to stall it open there is our first view of the forward hatch wide open [Music] SP if you just jumped in we are 38 minutes into today's spacewalk and the hatch is open on Dragon first view from a helmet cam looking out Dragon Space X we see installed ev1 is go to continue that structure you see there is check for ER I'm transitioning back from under the display SpaceX copies were with you in your helmet cam once again this helmet cam what we that structure we see is the the space walker this is Jared now egressing through the forward hatch of dragon resilience [Music] the first views of the first ever commercial spacewalk I'm at the bottom of the mobility is progressing I have a feeling the crowd is about to go wild [Music] fex back at home we all have a lot of work to do but from here bir s looks like a perfect [Music] Ro even one I'm going to step into Matrix One singlehanded Mobility demonstration Commander Jared Isaac men now emerging Matrix one watching from the nose [Music] cone up down left and right are [Music] three pitch and roller three y two switching single-handed operation toine static and with Dynamic disturbance switching to left [Music] hand up down left and right are threes maybe a two ditch is a four roll is a two Y is a two so these are the suit Mobility checks that Jared is single handed operations Dynamic and with disturbance are all adequate test Matrix one complete Hut Jack 5.3 PSI 4 38% RH 33 de 9 CSI SpaceX copies test Matrix 1 and HUD readout SC off Jack e one's good good good D stepping into vertical translation we're going to start with the horizontal bars all right we're going to transmiss over to vertical i' say vertical and horizontal are equally workable slightly favors horizontal I'm going to do a Max reach left hand at the to of Mobility a at the midpoint you have good video we just lost our live video stand by one okay Switching over to Max switching I'm holding up at the max any1 go ahead and continue the operation uh we'll let you know we're back on with live video copy that for your awareness Max reach L8 and the mid Bar N test Matrix 2 is complete C read out 5.3 PSI 33 decimal 9 celius % RH copy test Matrix complete and read out check e1's good good good stepping in the test Matrix three and three demonstration ev1 Space X for Ingress [Music] time go Space X recommended Ingress time of 02 flow plus 4 7 minutes got the G Ingress Time 4 S minutes and dragon we're back on live video from the nose con happy night [Music] and space at T1 I would say the handsfree demonstration is very comparable for the trainer in terms of the foot restraint SpaceX copies and ev1 when you have time if you'd like to return to the reach demonstration uh we'll take a look at that with the live video happy that test Matrix 3 is complete the Hut readout is 5.3 PSI 47% R 33 decimal 8 Celsius and stepping back into max reach copy test Matrix see stop the mobility Aid and uh let's get a Quick Crew off check e wanted I'm good happy that okay uh Max reach whether it's left or right hand sity about the same toit the mobility a and then the mid R copy we see it checking up from the [Music] bottom any go back space negative we got about 1 minute until ev1 [Music] Ingress 1 minute it's [Music] gorgeous you want to see if ADV you get the r right so ev1 we're checking out your helmet cam [Music] now now I'm checking out your nose going right now man looks pretty good copy we're no cone see you looking at [Music] us all right we're coming up about that 02 F timer time two check for inra E1 d e all right than one for the huge team effort that have took to get us to this point we know it's just the start and I'm transitioning back in the vehicle [Music] [Music] [Music] face at TV1 we taking a quick look here the Hatfield and what I I can see so far they look pretty good copy on the hatch seals and standby for transition to read off reset face this and ev1 is clear all right so Jared back inside uh we we heard him going through What's called the test Matrix uh it's basically just a bunch of Maneuvers using different hands using the foot Mobility is in progress calling out numbers right now though we're doing you just heard C Arthur call up three off resets so we didn't use any of the forward thrusters while Jared was out there we're re-enabling them putting us back in our perfect attitude before Sarah gets ready to go out the door fun thing to note it's still not a perfect vacuum inside a dragon is it's an open loop system so oxygen is kind of getting dumped into the cabin as this is going on so you got a higher pressure in Dragon than you have outside so we're not worried about Thruster pluming yeah now you mentioned Sarah um just like Jared she will have 10 to 15 minutes uh outside perform those same sets of Mobility tests as Jared um like we heard the core do um with ev1 uh they will call out when there's one minute remaining uh STX attitude reset complete ev2 go for erress there is Sarah's clear to proceed crew check for ev2 E ev1's good e2's good good 4 two good EV is going to go stand in the door and then step outside now this test Matrix that uh Jared just performed and the one that Sarah's about to perform they have both committed to memory um in order to execute these um we saw it being done pretty efficiently I can't believe how quickly that time went by Mike we were talking about how your Spice Box were hours and these guys only have 10 to 15 minutes and it just like that yeah it it can go pretty quick and uh but fortunately um feels look good I see a little bit of a boat between 14 and [Music] 13 so you're hearing Sarah call out some more of the seal check there as as she's exiting out three seated SpaceX copies that report good fix so this was something we knew might happen um and between 28 and 27 copy the crew trained on exactly what to do in the scenario just pop it back in one final between 19 and 18 it might be best repeated and hatch closer SpaceX copies can you repeat the location after Eva [Music] complete between 19 and 18 all right copy I'll track that and uh ask again when you're engress cppy eg2 is theing with EAS super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her Space Walk e one I'm going to hand this back to you [Music] like we mentioned Sarah will be performing the same uh set of Mobility tests uh so we will do the same uh try to stand by and listen to those coms [Music] I mean I said it before a lot of us work here CU we want to do this all right stepping into test Matrix one for singlehanded Mobility really cool to see one of our own out there that's awesome [Music] and ev2 for awareness we're watching from the nose con and cofy all I just say in all three translation AIS I'm having certainly cross purle mement forward back aming the B ever roll similarly it's left right and up down a bit of a PT but all are achievable right into is three now the [Music] three and C the f [Music] what than for for left man stepping into vertical translation SpaceX copies and ev2 for awareness we're tracking an Ingress time at O2 flow 59 minutes Cy 59 minutes horizontal bars are definitely preferred and I'm not be able to fatalize my body with single hand disturbances us left and right stepping into M reach do you have visual a firm we have visual on the nose cone puppy from bar four to Bar two from top down and some more reach from bar two up to Bar four SpaceX copies reach and tes6 one compl pressure 5.25 33.8 Celsius 37% humidity SpaceX copies HUD read out and test makers one complete I 7 the p62 like we mentioned before views going in and out doing during EXC me due to those ground station uh coverage gaps yeah we we coms some of the same coms are through satellites but we've got ground stations for video on dragon as you can see in the tracker we just flew over on New Zealand we're about to go right over the middle of the Pacific no ground stations in the middle of are actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got she got about a minute left and then she's going to start heading inside and see if with a little more work I can actually get between almost bar one and bar four on that stre space has copies and you could see the Earth dark and we flew into like an orbital all right and test Matrix to trying to combine them so we'll call that conce PE pressure 5.27 38% humidity 33.7 Celsius SpaceX copies Matrix complete and huded out St in s demo I'm able to engage and disengage my feet copy ev2 and once you are able to engage disengage we'll actually have you start Ingress we're just over 5 9 Minutes O2 flow [Music] poy that check for Cy coming on in all right and just like that Sarah's going to start making her way in here check those hatch seals again SpaceX copies on Striker plates and ev2 I have one more ask for the hatch if you can uh check that it as well when ready to copy ready [Music] copy copy and ev2 what I'll have you do is when you Ingress can you get eyes on the hatch handle mechanism and see if the handle has been stowed in the Do Not Stow uh window and report if you can see that check I think it's just outside copy just outside thank you just outside the range and for awareness I do see a couple of those same points folding again between 12 and 13 copy your go no mostly between 12 and 13 right now SpaceX copies at 12 uh if you can you're go to address those copy and [Music] work these numbers being called out represent the location around yeah the location around the circular hatch just identifying where these bulges are so Sarah is now reing that seal not quite able to reach the bath one so we'll proceed with clearing for hatch closure just like that we're already hearing about hatch closure it's incredible that these two Evas just in two blinks of the eyes are uh is clear on your screen there is SpaceX core uh or crew operations and resource engineer on duty tonight is Arthur baralt this is the uh the voice to the crew throughout uh their operations of course you know everyone has to sleep so we have different shifts for core um but Mike your time and dragon closed you're good Cy displ handle app fing for and [Music] closing once we get ground station coverage uh again we will be sure to bring you views within the Dragon capsule but right now Sarah is closing the forward hatch it sounds like we might give the motor a try he confirmed the hatch is visually indicating Clos hatch is verifi last hey commanding EV hatch [Music] Clos Eva hatch closed all Dr goes enabled [Music] Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress [Music] one and E1 copy one check secondary O2 valve Closing supp one I'm good TV1 close 8 close F two [Applause] close so a couple of real big moments right there Sarah was able to make sure Eva repress one copy secondary flow is closed and agree Eva repress one she was able to make sure that the seals were in good spot we got the hatch closed you can see of a half PSI for 8.3 see the pressure starting to take up just a final confirmation everyone confirm secondary or2 valves are closed keep1 close close four close 14 close C and we're through one for 8.3 all right so each of the crew just closed those secondary O2 valves on their umbilicals again that was primarily for cooling um during the space walk itself suit's still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon uh right after they get the hatch closed they're able to do kind of an initial pressure check cuz again oxygen it's an open loop system with these suits still flowing into the cabin you're able to see positive pressure response showing that the cabin uh the hatch was closed and was sealed uh we'll still do a leak check on our way kind of back up to our Al cabin pressure um so we're going to continue ticking up until we're about 8.3 PSI and then we're going to transition into the second phase of our repress um really the difference between repress one repress 2 is how frequently we're injecting atmosphere uh as kind of the the repress is also pretty unique with dragon um we're repressurizing with just nitrogen right now um which is a little bit unique obviously you have nitrogen and oxygen in your atmosphere uh with this we have O2 flowing into the cabin through the suits so we only need to add nitrogen so we're able to just basically add a bunch of that to really start getting your pressure up O2 continues to flow into the cabin through the suits and we're going to continue pressurizing until we're pretty much right back at our 14 right about our 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want to make make sure the crew takes helmets off and everything that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is microgravity everything's harder everything's on hard mode um and you don't just have natural convection so like I mean space station I think I've heard it a bunch of times Mike like you just constant noise of fans that's right almost yeah there's uh you've got to continually recycle that air um and one to help get rid of the CO2 right because as they're taking in that oxygen they're breathing out the CO2 and we need to to get that out of the system which is another important reason to have that air constantly circulating yeah um man that felt really quick that it did that was that was that was really cool to to see them outside for the first time and there they were what they were actually doing out there is a bunch of pretty simple tests as it looked but like this is just learning how the heck do you move because like just moving around yeah in micro gravity is tough it is tough Dron Space X we're about 2 and A2 minutes from Ted hand over around when you're in your short sleeves like we're in inside the capsule and when you put on that space suit uh it it's much more challenging to to move around with that on yeah and what they were really doing was just kind of like you put your hand on on Skywalker and then you're changing your pitch you're doing translation up and down and everything and then the one that that I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah and I think one of the other things I thought was interesting as you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab onto or utilize versus the vertical one so simple things like that you know for us it not a big deal uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that You' be able to share with us throughout this morning's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all of SpaceX and and really for for Humanity cuz it's just one of those small steps that's taken that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime all right good to see you hopp thanks by all right so repress is continuing we're a little over 4 PSI right now again we're going to keep that going up until we're a little over eight and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole process like right after we got on orbit yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their cute zero g indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and uh let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there coming in the tedris in and out so like we'll get it back but um so yeah just the fact that the uh all four crew members were able to just go right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during you you good we're good F you good just heard a quick check in from them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at 8 and then we'll let it hang out there for a couple of minutes uh Let The Thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressure starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for 1 hour and 13 minutes um it flew by so so quickly um six on cabin pressure approaching one PSI on pp2 I'm I'm sure for shared and Sarah flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core Arthur burial that's going to come uh once we are done with the repress repress operation uh we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the P2 environment in the suit using Nitro before they get out Nitro being that same air mixture that you have in your scuba tank uh if got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there we're just going to keep ping out should hopefully be getting video back from ground stations standby for transition toess 2 at 8 decimal 3 okay copy that sax we following along refes two at 8.3 and so once we transition to repress 2 once we're at about 8.3 PSI we'll stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we've got a good seal on that hatch before we finish the operation coming up on 8.3 there should be hopefully just about a minute and a half or so away from ground station so might get those views back inside a dragon I yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh PA refres che ev1's good good and yeah that coms we're hearing halfs side before we get the Le Dr monitoring check at 95 have a continual checks with all four crew members to make sure that everyone is good um if the answer to one of those checks was no there would be an option in this re press sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depressurize now this repress seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to tick up but we're going to pause at 9:00 we're going to do another cabin leak check so we should hear that momentarily time Eva repress to stop Dragon space is with you in Eva repress to stop waiting 5 minutes foral stabilization we're that space we're tracking 2 awareness we do a positive refresh R we are 30 seconds into the reck like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness pp2 is 1 decimal 35 halfway there the suits are still flowing that oxygen um and in a few minutes we will begin to flow we'll do a flush uh of of nitro uh into the [Applause] suits all right we got our views back there they are it's a little sad to see that forward hatch closed again it's it's got to be really hard when they tell you it's time to go back in just one more minute yep reminds me of when I was a kid swimming in the pool you know time to get out just one more minute me it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline 8 Minute Le Che throughout the sh good one good to good pp2 just passed 1.5 we're a couple minutes into our leak check you're you're seeing the pressure Contin continue to TI up we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that is why you're going to continue to see the pressure tick up you heard Jared call out the P2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14.4 or so and I mean that's it's a little bit lower than what we're walking around in now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that nitrox uh the K was talking about uh that takes them out of that pure oxygen environment and that's one of the final steps for we'll he hear that call from Arthur evva operations complete and that's when our clock's going to stop uh our space walk did start today at here at SpaceX in Hawthorne California and I'm Dan huitt from the communications team now the first Eva in history was performed in 1965 by Soviet Cosmonaut Alexi leonov followed just three months later by the first American spacewalk done by Ed White during the Gemini 4 Mission from those humble beginnings to walking on the surface of the Moon repairing satellites building space stations in orbit space walks are really a core component of human space flight well Evas are well established procedures for NASA and other space agencies this will be the first Space Walk using commercially developed hardware and procedures and spacex's brand new Eva suits which we debuted earlier this year now we've tested extensively in vacuum Chambers here on Earth but this is the first time that the suits will encounter the vacuum of space and on board the dragon spacecraft right now is the Polaris Dawn crew starting off you got Mission Commander Jared Rook isaacman Mission pilot Scott kid potit and for the first time ever we're excited about this two SpaceX employees Mission specialist Sarah Cooper Gillis and Anna Walker Menan who's serving as the mission specialist and medical officer for members of the crew have been orbiting Earth for two days since they lifted off from launch complex 39a at Kennedy Space Center on Tuesday September 10th it adds up to about 15 to 16 orbits around the Earth every single day in counting on day two of the mission as you can see there on your screen Dragon fired its forward Draco bulkhead thrusters to send the spacecraft soaring higher than any dragon mission to date reaching the highest Earth orbit ever flown the crew uh topped out at more than 1,400 km breaking the record set by gmany 11 a half century ago when that spacecraft reached 13 excuse me 1,373 km this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 since that time dragon has gradually lowered its apogee or the highest point in its orbit as the crew got ready for the space walk today they started to Dawn or put on their Eva suits just a little bit of time ago and they've been undergoing a process called pre-breathing where the atmospheric pressure inside dragon is slowly decreased and oxygen is increase to prepare their bodies for the Eva suit environment we're going to dive more into the operations of the spacewalk a little bit later and we're going to be hearing in live communications with the crew throughout so be sure to listen in as those happen yeah it's going to be super exciting to hear that and as far as views goes we'll have dragons regular internal cameras that we have seen before and up to three external cameras one aimed at the hatch uh kind of like what you see there uh one on Dragon's nose cone uh which actually is the one that's there that's the the the camera on the nose cone and one on the newest piece of Hardware that you see there in that view we that is the Skywalker um which we will come back to shortly we may also have helmet cameras that will give us a firstperson view from the crew which will be incredible now since we are not using starlink to uh and enable views today there will be moments of expected loss of signal due to ground station coverage so those views may be interrupted from time to time but generally we expect to get some great shots today and as of right now we're less than an hour away from the start of the Eva for now though let's learn a little bit more about the mission and our crew the Polaris program is a first of its kind effort to rapidly Advance human space flight capabilities while continuing to raise funds awareness for important causes down here on Earth today's goal is to demonstrate critical operational capabilities that are going to serve as those building blocks to help further human space exploration pois Dawn Mission has a lot of firsttime objectives so the pois program chose a crew of experts who know each other so they can tackle this mission's challenges as a team first up Mission Commander Jared Rook isaacman also served as the commander of inspiration 4 the world's first Al of Ian mission to space Jared holds several world records including two speed around the world flights in 2008 and 2009 for the Make A Wish Foundation he has flown in over 100 air shows as part of the Black Diamond jet team dedicating every performance to charitable causes in 2011 Jared co-founded what would become the world's largest private Air Force dren International and that trains Pilots for the US armed forces in addition to his role as CEO of Shift 4 Jared is an accomplished pilot and astronaut with over 7,000 flight hours next up Mission pilot Scott kid potit who served as the mission director of inspiration 4 and he goes by the nickname kid which is also his call sign he's a retired US Air Force Lieutenant Colonel kids served for 20 years in roles that included commander of the 64th aggressor Squadron Thunderbird number four demonstration pilot US Air Force weapon school graduate operational test and evaluation pilot and flight exam he's a command pilot with over 3,200 flying hours logged over 400 hours of combat time and following his Air Force career kid served in various roles including vice president of strategy at Shift 4 Mission specialist Sarah Cooper Gillis is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew 1 missions and most recently directly trained the inspiration for astronaut Sarah is an experienced mission control operator who has supported real-time operations for Dragons cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for dragon's human space flight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program full-time and capping off the Polaris Dawn crew mission specialist and medical officer Anna walk ER Menan who serves as a lead space operations engineer here at SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragon's crew capabilities and develop critical operational responses to vehicle emergencies prior to SpaceX Anna worked for seven years at Nasa as a biomedical flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going to space that's clear but let's take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isman I'm Scott kid potit I'm Sarah Gillis and I'm Anna Menan and we're the player Don crew I Love This Crew I mean all of them are just so hardworking so smart kid poti over here is our mission pilot talk about a career in the Air Force doing every job as a pilot than than anyone would aspire to achieve and having somebody who has you know been there before and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always there glue glue you are always there they predicting what every person needs um and he's needy what our commander Jared I think he is incredibly sharp that's right something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical competence we don't get out of any engineering update or brief or go through a procedure or debrief without getting into the weeds and making sure every tea is crossed every guy is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared par that served her in her role as core it serves her in her role as a trainer Anna you have this incredible joy that you bring to everyday life it is infectious it makes us all smile feels like she always has this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then as a biomedical engineer and a background like that inspires like a ton of confidence that you go up there if uh if people aren't feeling right that she's going to be there to take care of I cherish all the moments that we've had uh in these experiences and uh we're just so excited to to go to space now that you know a little more about the Polaris Don crew let's recap the mission so far and what's coming up next since liftoff and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours is demonstrating the Eva suit's pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I mentioned earlier on day two dragon proceeded to a high apogee of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the spacewalk Dragon has been executing a series of a apogee Ling apogee lowering phasing Burns by now dragon has lowered itself from the highest apogee of the mission of more than 1400 km to about 190 by 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude Children's Research hospital um and they they're joined Live While polaron crew member Anna Menan read from her new book kisses from space along with the patients and families at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the poist dawn crew Enlisted the help of Childhood cancer survivor live to create the missions Zerg indicator while not a St Jude patient herself Liv met the inspiration for crew and inspired by the mission of St Jude she agreed to share her talents to support Polaris stone is live and I spell it l and then an apostrophe Mar escalation Park I can tell you anything about space from the miles from Earth to the Sun to every Mission basically I had cancer in 2021 cancer survivor like Haley I really have a passion for wanting to help St Jude and other kids who have those struggles as I had so I first met Liv a couple days after I got back from space at our Splashdown party and I got to meet her family and they told me about her journey that she was on I remember that she gave me a card she had written and it said thank you for helping other kids with cancer like me I hope to go to space like you someday and my eyes just filled with tears whenever I I read that basically my one passion is to um be the first child in space Liv was really close with the players Don crew and they asked her to design the Zerg indicator a zerg indicator is like a little plush toy that floats in the air it basically shows that you're in zg they kind of hide it over in the corner and then once you hit zg it'll float up and reveal itself my main idea for asteroid is based on eon dog POI I I've always loved Sheba they've always been really cute and then when I heard got poy I was like done I love her I want asteroid to be for every child and help them see oh asteroid went to space and I can I can achieve my [Music] dreams we are also flying Liv's original drawing that you see there that was used to design the zerog G indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital all donations from the sale of asteroid will will be General donations to St Jude the inspiration 4 Mission helped raise more than $240 million for St Jude Children's Research Hospital and polaron will continue to raise funds and awareness for St Jude while partnering with the organization to provide healthc care in underserved communities around the world now if you want your very own asteroid they are available at shop. spacex.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the way so be sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got I snagged one I got in there I got a kid who nice needs one yeah all right now the first phasee of the spacewalk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre-breathe process started that's when the oxygen levels started to increase incrementally as the actual the cabin pressure inside Dragon was started to get incrementally lower the pre-breathe process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any space walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure de of in deep water back up to the surface and to do all this dragon's just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in in the suit during the spacewalk itself they've got the ability to pause the process if they experience any discomfort but the ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude on an airplane um all four astronauts are going to be suited for the spacewalk today cuz Dragon does not have an airlock that's also kind of why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with the stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah just going to be lightly secured ahead of the spacewalk since they're going to be moving around and eventually heading outside as we listen into comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support two is Anna again they will not exit the dragon during the Eva but make no mistake they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rot rotate those upright during the Eva just to give more room to move about after that seat rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tabs in the health of their suits and they'll get some other stats of their suit operation during The Space Walk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations brief from the SpaceX team the crew will announce their go noo stack and then it'll be time for the spacewalk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the crew suits until we complete the repressurization of the cabin and just prior to we get to cabin venting pure oxygen is going to start flow into the cruise suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the sun this will help keep temperatures Communications and spacecraft power stable during The Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during The Space Walk he's going to be the first to exit the spacecraft he's going to go outside and he's going to do a a series of Mobility tests these are kind of the core component of the spacewalk today it's going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into Dragon after that ev2 or Sarah will step out into space to perform the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit then after she's completed her test Sarah will stand by near the hatch for the actual closing and then at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is suited up and awaiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the Space Walk and before we get there though we're going to expand the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back K in Hawthorne with you tonight on this uh very memorable night for sure yeah absolutely uh now Eva may be new to SpaceX but uh you have participated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two missions you the first one was back in 2013 and I uh I went up on a Russian soy use and on that one we had two space walks and the interesting thing about those space walks is they weren't planned they were what yeah they were a big surprise for us uh contingency Space Walk and of course surprises happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a space walk as everybody was getting ready to celebrate Christmas just helping deliver presents that's right that's right and then your first play was on the so but your second one you were the command of crew one I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than anybody cuz you you actually got the call at home while you were docked up there that's right it I me I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was in a great amazing group of people not only uh Victor Shannon and suichi but but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough crew stations and actually you can see a picture of uh of where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the station where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the SP get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for crew one weren't they they were yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees and somebody else getting to uh getting to test them all the time so uh yeah it was pretty neat to to get to see that switching it up a little bit because we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to, 1400 km uh we like to talk about something called the overview effect so kind of that first that oh and we're getting some coms from our crew too yeah nice space Dragon radio check C clear kid H me got you loud and clear dolphing continues unless though just going to be right cab C that kid make that dnie all right some some quick com checks we heard kid that Scott po he's going to be one of the support crew in there today so our our first com's down uh as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back and I mean you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overview effect is definitely real but when I first got to space um on that on that soy use uh gu how many years ago almost N9 years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now this really that's pretty but oh no um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you'll hear people talking about that that small sliver of atmosphere and you you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me a lot of questions and made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it brought as many questions as it did answers hopefully a bunch of bunch more trips then right that's yeah that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank White originally coined the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habitable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different emotions that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moon rise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to Mars and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of SpaceX SE four is next support two is next and then ev1 and two are surely [Music] behind copy on that crew status getting a quick quick crew status from kid H yeah I I think I speak for a lot of space exors we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dragon and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean spacewalks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first Space Walk is contingency we had a failure and so sometimes when we're going outside it's it's not planned and you have a compl component that that is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out and we're putting in a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar rays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Don crew is going to do today and you're just checking out the suits and checking out the equipment that that you're going to use in future space walks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um basic for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction requiredby actually uh if I can I'm just going to jump in on that that's actually a very important call that was made you heard them say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around at what was that and so you heard them give them a warning that we're going to turn on some fans and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those spacewalks where I was uh at you know outside and and what are you proud of you're you know it's it takes so much to put these vehicles up into space and and so when you go out on the spacewalks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because people are depending on you and couple people watching over your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good station's back up 100% just like okay that's that feels great Dragon Space X our fan commanding is now [Music] complete all right hopefully no surprise sounds in there for him so I mean spacewalks are something that you you train the heck out of they're they're playing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a space walk yeah so I mean one of the first challenges that you're always worried about is the how your suits functioning right because that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground and monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between you and the and the ground and so they're making all of those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about spacewalks that uh maybe people don't realize is you know you f focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they ex these space walks um they they you you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk it no it never felt a c walk at at all um you know it because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely um very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on you're more familiar maybe is a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I will equate a little bit of of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all of that kind of nervous energy as you're getting ready to go out well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on SE rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them upright that's just is going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is spacex's 14th human space flight Mission since 2020 when Dragon became the first private spacecraft to take humans to the International Space Station it's also the first private spacecraft to take an all civilian crew to orbit during the inspiration 4 Mission in 2021 and just prior to Polaris Dawn Dragon completed 46 launches 13 of those are human space flight missions and it's since flown 50 astronauts representing 14 different countries throughout all of those missions dragon has helped support more than 1,000 experiments in space pretty incredible stats there um and even from low earth orbit dragon is helping lay the groundwork for deep space exploration through missions like inspiration 4 and Polaris Dawn we are rapidly expanding our knowledge of how humans will adapt live and work in space designed to be the safest spacecraft ever flown the fully autonomous Dragon stands nearly 27 feet tall and 13 ft around dragon is capable of carrying up to seven passengers to and front Earth orbit and Beyond but today it's carrying the four members of the Polaris Dawn crew and the crew is currently living and working in the top portion of the spacecraft that's that white section that you see there also known as the pressurized section this allows for the for the transport of people and environmentally sensitive cargo below that dragon's trunk it sits right below the pressurized section that can carry unpressurized cargo on resupply missions and it remains attached to Dragon until shortly before re-entry into Earth's atmosphere and as you can see about half the trunk is covered in solar panels those provide Power to Dragon during the flight the other half is the radiator Dragon itself is equipped with 16 Draco thrusters we got really cool view of the four forward bulkhead ones firing earlier on this flight with lights on Earth behind you those are used to orient the spacecraft during the mission they also get used for apog and Pary raise and lower Maneuvers orbit adjustments and attitude control for the Eva the Draco are going to be used to reposition Dragon so the trunk is facing the Sun and they're also there to be used for reorientation during the spacewalk if needed in order to accommodate accommodate a spacewalk this is the first dragon to be outfitted with a Skywalker in place of the Koopa observation Dome the Skywalker that you see there looking up at it uh from the from basically from underneath it um the Skywalker is a structure that is mounted to the top of the Dragon capsule and the astronauts will use this to assist in exiting and re-entering the spacecraft during their space block the team also added additional nitrogen tanks to assist in repressurization of the capsule after the Eva another new feature on Dragon is the addition of a motor plus hand holds and footh holds inside the spacecraft to help with opening and closing the hatch during The Space Walk This Dragon also carrying what we are calling the starlink plug and pler making this the first mission on Dragon to use the starlink network in orbit inside a dragon is a router connected to a user terminal in Dragon's trunk and then this terminal is linked to a new plug-in player device that's mounted nearby while we're not using starlink for continuous coverage during this operation we've been testing its ability to establish and maintain laser Communications with our starlink satellites there and orbit that are below dragon dragon has proved to be quite a versatile spacecraft it can autonomously dock to the space station when outfitted with the ISS docking adapter and when it's intended for free flyer mode the docking adap adapter can be swwa drag and you guys are welcome to come back aboard if you want SpaceX copies don't have uh ground station right now but we'll go ahead and bring cameras back on board so we get it when we do have ground stations quick comms there with SpaceX core uh from the Dragon capsule that was uh the crew just letting the folks here uh in Mission Control letting us know that it's okay to turn the onboard cameras back on once we have uh coverage for those cameras um but getting back to the different um configurations that we have for the Dragon capsule um I was talking about the docking adapter previously when the Dragon capsule is intended for free flyer mode docking adapter can be swapped out for a Cupa uh which is the one in the middle there and that is used for the best views that you can get while in orbit and then of course our newest option the Skywalker Hardware to support extra vehicular activities and that's what the crew is going to be using this morning so those are the current three ways that dragon can be configured to support different types of missions but hey you never know what's to come we always got something up Our Sleeve right now Mike crew one broke the record for the longest space flight by a us crew vehicle surpassed the 84-day mark that was set by an Apollo capsule during that final flight to the Skylab space station in 1974 what was it like cuz we we went over it you literally called Dragon home during that time what was it like to live in there so so first of all I got to say it's pretty exciting because uh the the dragon that they're using right now is the dragon that I lived in that took us to orbit uh res yeah we affectionately called resilience uh and and it was a it was an amazing spacecraft uh it it uh from a standpoint of living inside it and um again it it a lot of room actually compared to some of the other crew quarters that we had on board and uh and and plus just uh you know being able to to uh spend all that time in it you know I'd call my family every night before i' go to bed and I'd be looking out the window uh at the Earth uh as as I was doing that it was uh very special did did any of them get jealous cuz you had the window seat well yeah there was a little bit of that certainly uh going on up there nice now as you mentioned this Dragon capsule that the inspiration excuse me that the Polaris Don crew is flying in was previously used uh really debuted on the crew One mission hence why you guys had the um honor of naming it in the first place but this capsule was also used for the inspiration for mission that uh Jared also commanded um what is your take on uh this being one spacecraft but supporting multiple missions I think it's fantastic it just shows the flexibility of the design that SpaceX made when uh when looking at the crew Dragon Vehicles so I I I think it's very exciting to see a vehicle that can that can go from one mission to the other and and quite frankly do it quite uh quickly as well I think I remember the exact timing uh from our mission and when we landed to win inspiration 4 launch but it wasn't a very long time and yet you were able to take that docking adapter off put the uh KOA on in a in a very short time which is also pretty impressive I actually have that noted here uh crew one took off in November of 2020 and inspiration 4 lifted off in September of 2021 that's that's a we landed in May of 21 and So within that short period of time you reconfigured the vehicle and uh and we're able to put that c on and launch yeah impressive your mission patch sticker is in the is in the capsule that they're in now and add their own sticker to as well all right well as you can imagine dragon has undergone some changes for this and with changes comes extensive testing for the mission and all the modifications that we made in preparation for today had to go through kind of their own test regimen yeah testing is a critical part of qualifying a spacecraft like Dragon for flight rigorous testing helps identify and mitigate potential risks verify system and component reliability and helps ensure that the designs meet the mission requirements there are many types of tests a spacecraft might undergo when qualifying for flight including structural thermal vacuum radiation software and Integrated Systems testing one of the tests the new Skywalker Hardware underwent is thermal vacuum testing this actually tested how Skywalker withstands the extreme temperature swings that it's going to see while it's in the vacuum of space and while Dragon was being put through all of its Paces the Polaris Dawn crew was going through the same SpaceX training uh as part of our that we give to NASA astronauts they also had a train to perform their Eva though for basic training at SpaceX Hawthorne they train on everything from orbital mechanics to just how to live and work in microgravity also ran through numerous simulations of what the full mission would look like while they were seated inside of our Dragon trainer in addition to ensuring that they're familiar with spacex's Falcon 9 rocket and dragon spacecraft the crew went through an extensive training regimen to build their physical endurance and mental toughness ensuring that they are well-rounded and prepared for space flight and today's Eva now switching gear is one of the coolest things designed in-house by SpaceX the Eva suit has all the functions of our original space suit with the added bonus of allowing astronauts to exit the spacecraft while in orbit and this Mission this Mission gives us a great opportunity to test our Eva suits in space building a base on the moon and a city on Mars will require thousands of space suits so the development of this suit and the Eva performed on this Mission will be important steps toward a scalable design for space suits on future long duration missions as we mentioned SpaceX designs and manufactures our own suits and we have a little behind the scenes look for you something most people don't get to see the inside of our very own suit lab an Eva suit is an extra vehicular activity suit which is a space suit that can go outside of the spacecraft to do a space walk we started with the Iva suit that we have the intra vehicular activity suit as a kind of starting point and looked at it and said what would we have to change about this to be able to support a space walk so the first is mobility um the crew will have to do a lot of moving around inside of dragon to get outside and do The Space Walk we had to add in new joints um and new features in the suit to allow them enhance Mobility while the suit's pressurized when a crew member is pressurized in the suit the soft portions of the suit become rigid they need actual fuure and rotational joints to allow them to move around it's kind of like a suit of armor uh made of fabric we innovated in flexor joints to allow easy bending at the elbows and the knees as well as has a collapsible Rotator joint that exists on the shoulder which allows the suit to remain nearly fully soft but when pressurized is a rotational bearing the difference between the Iva and Eva suit is that on the Iva suit the zpp system location is in the inseam uh but since we needed to have lots of Mobility on our Eva suit that was not the Preferred Choice by moving the sipper system from the inseam to the waist we mitigated risk of the stress of the sipper and another big element was also the the thermal side of things the crew is obviously exposed to a much more extreme thermal environment during the Eva so we want to make sure that the inside of the suit is comfortable for them um and that as they interface with parts of the vehicle that that is safe for them to touch as well the EV suit is built and designed here at SpaceX in Halton California we wanted to have something that's easy manufactured that we can handle here in house so we developed this new material so it's fabric based we actually added a new layer to the suit uh which we refer to as the Faraday layer and this is a conductive cage around the suit that Shields the suit from external electric Fields the helmet on the Eva suit uh looks very similar to the Iva suit but is really an all new design of that helmet um it's much more robust from a thermal structural perspective since it will be taking more extreme temperatures we are really excited to introduce this new single Paine visor helmet to the world of SPAC the Eva suit visor is made of polycarbonate and is coated with copper and I or indium T oxide these two Coatings together reflect the Sun away from the crew as well as reflecting infrared heat back to the crew when they are facing deep space our suit has a HUD or heads up display which is a small display screen in the helmet which is transparent which allows the crew to see through the display to have unfettered access during the Eva but it also provides critical Telemetry to the crew so pressure temperature relative humidity we're trying to improve the technology and streamline it in one way and at the same time we're also trying to get it more and more manufacturable with each generation the ultimate goal is that you can put on a space suit and go out and get work done anywhere in the solar system um and not feel like you're wearing anything more than you normally wear every day [Applause] [Music] we also had a chance to talk to the SpaceX team that developed some of the hardware and procedures for our first Space Walk let's hear what they had to say Eva stands for extra vehicular activity and it's any sort of operation in space where a human is getting out of the spacecraft so in the case of Polaris daon we're going to be testing the mobility of the suit we're going to see if the inp space operation matches the training we've done here in Hawthorne there's really a lot of different things that can happen during an Eva and this is the first step for Dragon and SpaceX when I first started working at SpaceX I never thought I'd be training a crew to do an Eva it's brand new it's so unique we've never done anything like this before and so we wanted to make sure we had the best possible training program for this Mission we want to see if we can train a space walk on earth in a way that's representative of what it feels like in space even though only two people are going to be going outside during this first Eva all four crew will be in Eva suits going down to vacuum Dragon was always designed to vent to full vacuum but we've never taken full Dragon capsule down to vacuum and this will be the first time we do it in space we actually put crew into a chamber at Johnson Space Center in Houston and had them live the exact profile that they will experience and making sure that no one actually experienced uh decompression sickness we have a couple new training assets for player ston to train the Eva specifically the suspension system that we have is situated on top of the platform of our capsule Simulator the lines drop through the hatch they attach to a single crew member inside the capsule we can lift them up and get them situated so that they can eress the capsule and perform their tasks at Skywalker the mobility Aid the sky Walker what's amazing to me is a lot of people are going to think it's a metallic structure just bolted to the top of dragon but a lot of development effort testing went into the Skywalker so we actually used similar technology as we have in the super Draco Chambers to apply a thermal barrier coating to the outside of the Skywalker that is going to be a really really amazing Mobility G on the front end of dragon we also developed a sideways simulator so we flip the hatch on its side in the event the hatch fails to close they can manually close the hatch we had them do that in a sideway suspension system so gry isn't helping them close or helping them open that hatch mechanism it's new development for Dragon it's new development for SpaceX and the industry as a whole so this is a great example of where polaron is forcing the team to innovate in a way that adds safety and reliability to every dragon mission going forward that's this huge challenge for us to go solve but that's also an opportunity for us to solve the problems that we have have to go figure out anyway for our larger goals like putting people on Mars the Piston objectives are the first step towards that ultimate flight with with humans inside of Starship which is right along the SpaceX development path that that we have towards getting to the moon and Mars love seeing how not only the suit but the space operations for the Eva itself uh came together and were developed uh now we are still counting down to the spacewalk this morning uh the crew is or excuse me the crew on board is completing final fit-ups and we're going to be standing by for seat rotation and suit leak checks so we're continuing to truck along to the the the main event uh now Mike you obviously went through some of the suitup process that we saw in that package in terms of um the the development of the suit and how it's custom fitted for each individual and that's that's the same case for an Eva suit so maybe you can share with us what that experience was like yeah it it's extremely important uh to to have a suit that fits whether again it's the Iva the EV evva suit or the Emu that we wear with NASA when we go out on the spacewalks and the reason for that is because if it doesn't fit right it can be extremely uncomfortable you can get what you call hot spots or uh there can be a a a place where the a crease when it gets pressurized can really put a a uh a hard point on your arm or something of that nature so so having a good suit fit check is extremely important and and it's one of the things that was kind of fun as well because you get to spend a lot of time with the the suit team here with Chris and Eric and Mar they're fantastic and and I mean just over the years they've gained so much experience and they can really help you hone in on what a the really good fitting suit is is like with the just the way they ask the questions and lead you through that that process wow what are what are kind of the Sensational differences from being in like the Iva suit cuz a lot of times the Iva suit when it gets pressurized you know it fills up but you're still in like a pressured environment with Eva suit you're in the vacuum right and so like what's what's it kind of like yeah so you know that Iva suit it has a different purpose right and that the purpose of that Iva suit is to Keep Us Alive in the event of some type of an emergency that might happen during a launch or a landing and and so that's that case where either you have a fire or you have a depress event and so that suit's going to pressurize and so in that case we're not as worried about like the mobility of of the suits you just want to get home and and do it in a safe way and so you need to have enough Mobility to still be able to control the spacecraft and and do the things you need to do but but you're just not as worried about it because you're not trying to perform a maintenance activity or or something like that when you're going down on the on a on a spacewalk and and so I think that's that's one of the the biggest differences is between the Iva suit and the Eva suit is just what the purpose of it is and what you're trying to do with it yeah that feedback loop um is so important to be able to communicate what feels good what doesn't um because I imagine um you know as you're out there and having to perform you know as you mentioned maintenance activities uh among other things that the functionality of your body is critical to to to perform those it really is and probably one of the hardest I think parts of the suit to design is the gloves right because absolutely you know you hear us use the term it fits like a glove right we use that a lot but but you don't realize how much you use your hands when you're outside on a space walk as opposed to say your feet when you're you know cuz in space we don't use our feet our legs as much as we do our hands and and so when you're in a a pressurized suit like that and you're constantly grabbing and reaching you are overcoming the pressure of the suit and your hands can get just exhausted and you can get those hotspots um I had some issues with my emu gloves when I first started training at Nasa and I would actually get uh what's called delamination on my fingernails yeah and and so there's just little things like that that it really matters how well that suit fits and and how well it functions and and so uh it you don't realize how important that is sometimes yeah um now we are going to be stepping into suit leak checks soon um can you share with us a little bit about what that process uh entails um and and and more importantly because you you've actually experienced what it feels like to go through suit leag checks what what that experience is like extremely important part of the whole process right because before you take the cabin in this case all the way down to vacuum you want to make sure that your suit is maintaining the pressure that it needs to and and so it's a it it's a not a very long process it's usually just you know a few minutes to two or three minutes um and you know the the interesting part is if you don't pass that lead check what do you do next and and so there's always usually procedures associated with that as well that start checking your zipper start checking how you've closed things up did you not get something sealed quite right um and and so it's always a good point in the mission when uh whether it's on the Launchpad getting ready whether it's in the airlock getting ready to go out the door when you when you hear that yeah good leak check uh because now you know that you're ready to go so today's going to be kind of unique because all four of our crew members are going to be like doing The Space Walk they're all going to be exposed to the vacuum of space but I mean even when you did space walks it's it's never a solo act right like you're always out there with a partner you you are it's uh it's extremely important in fact one of the hardest parts about our training for space walks is what we call incapacitated crew and so you need to always be able to get your crewmate back into the airlock if something should happen if uh if they should no longer be conscious and and something of that nature and so we we actually do spend quite a bit of time and that's why it's extremely important for us to go out in pairs because things can go wrong um and and so you want to be prepared for those those moments yeah uh that's a great Point Dan to make that um while only Jared and Sarah are going to be somewhat exiting the spacecraft um all four crew members are going to be exposed to the vacuum of space and it's actually going to set a new record for most number of people exposed to uh or not them without a suit but like yeah in the vacuum of gravity all at the same time yeah that's actually interesting I never I never actually thought of that piece of this Mission and the fact that you're going to have four people on a spacewalk I I know at one point on a shuttle mission we had three three folks outside on a on a spacewalk um and so yeah that's a that's a big deal and and kind of exciting you know one of the one of the things we do on the on the space station of course is We Have astronauts that are still inside and if we do get into those emergency situations they're there prepared to help us uh get back into the airlock and and uh and get unsuited and and things of that nature so of course when you have all the crew it just makes you think about those emergency situations probably in a little bit different way than we than we do on station yeah and hey if you're just tuning in we are still waiting to really kick off our space walk today so right now the crew is inside the space spacecraft they're getting suited up we should be hearing some coms from them pretty soon and then X Dragon um ev1 is completing glove zipper closures but at this time we are ready for seat rotation copy that for SE rotation can you confirm crew is ready with the current glove zip props all right I I guess they just needed me to to say it was coming soon and then and then there it is uh but uh we are going to hear the seat rotation coming up soon again they're in their recline position and do stand by get seat copy standing by so they're going to get those seats rotated and then we're then we're pretty much going to be ready to start getting into things and uh our Eva going to officially start when we start flowing O2 into those suits um and so that'll kind of start our clock we're going to be showing you some of the Telemetry so all those numbers the bottom of your screen you've got a couple right now uh that one all the way in the bottom left corner that's your dragon that's your dragon cabin pressure that's in PSI ready for SE location space copies initiating seat rotation great news there that's going to help give the crew a little bit more room to move around uh during The Space Walk and after we get through the seat rotation we'll be able to perform those suit leak checks that we were just talking about yeah before they do that they'll do what's called a tear so it's kind of like if you're ever using a scale you zero out the scale before you put something on it it's essentially what we're doing with the suits they'll get like a baseline reading and then as we start to actually pressurize the suit we'll be able to measure that against the Baseline make sure everybody's got basically a nice seal before we start that vent yeah that one's pretty important that was pretty important yeah um so a lot of that's coming up again some of the data on your screen you've got cabin pressure you've got suit pressure Dragon SpaceX seat rotation complete and nominal all right seat rotations complete so now they're going to start doing that tear getting ready Cy and can I get a confirmation of completion per the call out in 2 decimal 18 complete with 21 copy at this time you are go to step into section three and tear suit deers now just a quick reminder in case if you missed the top of um the show we're we're going to be referring to the crew a little differently for the Eva activity um than we were previously so we heard Anna uh talk ev1 that was referring to Jared so his basically his call sign for this uh spacewalk operation is ev1 um Sarah's call sign will be ev2 Anna will be support two and uh Scott will be support one uh also Scott and Sarah are switching seats uh I perhaps they already have cop you stand by for HUD power for pressure sensor checkouts okay so our suit tear completed so next up is going to be the HUD checkout so the HUD your heads up like real quick we do have on your screen though that's your seed order so uh you've got ev1 Jared is in that seat he's going to be in that seat right now but once we actually get ready to open the hatch and everything he's going to be positioned kind of over by the hatch and then Sarah ev2 is going to be in one of those Center seats then you'll have Anna and kid on on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks in three decimal 2 so again that's our that's our SE layout we just heard the Huds are powered on so they've got heads up displays actually being kind of projected on their visor in their helmet which if you if you've ever seen space suits that's always kind of felt like that's that Space Age Technology that we're missing because Mike you guys use kind of a a a simpler but a little unorthodox way to see like your suit data yeah that that's right Dan it's uh of course this the suits and is that check out complete onom nice copy swapping the backup sensors standby to repeat H checks so of course the suits that we use for the the space walks on station are a little bit older they've been around for for quite a while and and so some of this technology uh you know look it's our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chilling yeah so there out of his seat that's Commander Jared uh who like I mentioned before will be referred to as ev1 behind him we can see already in his new seat uh pilot Scott kid potit uh he will be support one and then moving around in front of us is Sarah who will be ev2 and then just out of view underneath the camera but I think you can see her visor is um Anna Menan who is support to Dragon SpaceX we're on backup sensors repeat Hut checks the crew is going to check out those heads up displays one more time real quick check out back copy good Huds returning to primary standby for helmet camera checkouts on that heads up display they'll be able to see the O2 flow timer that's kind of like our mission clock essentially like once the O2 has started to flow to their seats and they know they've got about an hour and 50 minutes just under two hours for the whole time uh they'll be able to see their suit pressure temperature basically it's a way to kind of keep an eye on things and we were talking about it a little bit Mike but on the Emu is a little bit different yeah the Emu is certainly different uh a lot of that kind of information is on a on a display right in front of you that you have to kind of look down to see and it it can be pretty challenging to see in fact a lot of the information you have to use a mirror on your wrist uh to be able to to read it and know what you're richer controlling as well uh you mentioned the timer of course we don't have that kind of information on on ours and I'm not sure I'd want to know that because I'd feel the pressure of I got to get a lot of things done I'm running out of time yeah all right um so they're they're going through these HUD checkouts again pretty soon Dragon Space X powering on helmet cams we're gonna get the helmet cams powered on again give you that kind of look right over their shoulders yeah pretty excited for these we've uh seen them utiliz during the training uh sessions that the crew has undergone and we're so excited to to see them live today yeah I I tell you the helmet cameras I mean it's going to be fantastic views right that we're all going to love but but there's also a very important um role for those cameras as well like when we have the same thing we have helmet cameras with the emus and what it allows is your ground team Dragon facex suit cameras powered confirm good health so it really allows your ground teams to to kind of be able to see what you're doing and see a good video on and almost double check your work copy check out's complete Huds will remain powered proceed to step 3 decimal c 3 operations review through 3 decimal 8 report one complete all right so we got through HUD checks we got cameras on powered ready to go so right now the crew is going to go through they're going to do kind of a final review of all of their procedures like you talked about this a little bit like these things are so choreographed because even if you couldn't see the clock like you're on the clock so you've got to you've really got to make the most out of like every single second you're doing one of these you do and and of course you see that with with today's space walk as well space X repeating checkouts are complete Huds are going to remain powered proceed to step 3 decimal 3 operations review through 3 decimal 8 and Report when complete happy and and the reason it's so choreographed and important is because you only have so much time outside right you only have so many consumables that allow you to go out there and so you want to take advantage of all of that and you want to have every step very well scripted so that so that there's not a lot of wasted time now that being said it is nice when you're out there once in a while to just kind of take a moment look around enjoy the views kind of try to absorb where you actually are which can be pretty incredible as well every every once in a while guys I'm a little tired I'm going to take a minute that's right I need take see my house from here that's right yeah all right but like it's it's awesome we're seeing the crew inside we're getting close to the start of today's spacewalk we're going to start flowing O2 to the suits and that's when our clock's going to start right now they're just doing kind of final cabin configurations they're going to check the lighting uh they're going to make sure that their umbilicals are in the right spot that's one of the things you'll see that's actually one of the the the roles that our support uh crew members are really going to that's kind of one of their one of their primary jobs during the spacewalk is to manage those umbilicals for you guys Mike you had one that's uh what plugs into kind of the leg in your suit and that's what's providing like the breathing gas coms connections all of that stuff uh for this spacewalk today it's a little bit different this one uh that uh they're going to be using has some tethers in it um for Anna or for Sarah and um Jared it's about 12T long so it's like about double double the length of what you guys so so it's Dual Purpose right it's it's providing them the the air and the cooling that they need while they're out on the spacewalk uh but it's also providing that safety piece right so that if uh if something should happen they should slip or um that that they're not going to go floating off in the space with the Emu uh that we use on the space station we actually you know all of those consumables are a part of the suit itself and we have a separate safety tether that the first thing we do when we open that hatch and we go out as as we hook up that safety tether and it's an 85 ft reel that uh as you're moving around it it goes out with you to again protect for that crazy moment when maybe uh an emergency happens and you come off station how how hard was it to manage all of those tethers I feel like every time I watched it was like there's no way in heck that this getting SED on no you're absolutely right because everything and and you talked earlier about making sure there was no loose items in the cockpit right cuz when you open that that hatch uh things are going to want to float away if they're not tied down or stored or anything like that so when we go out on a spacewalk not only do we keep us Tethered to the spacecraft but any tool any part that we take out with us also has to be tethered and it can be quite a challenge to manage all you'll open up a bag and there there's 10 pieces of Hardware in there with 10 different tethers and they get all tangled up and and it can really be pretty challenging it's important though um we simplified that a little bit for this Mission um we actually basically built in that tether into the umbilical one of which you can see actually they floating uh under Jared's right arm so not only does that Pro provide airf flow and comms and uh all the normal connections that we have in the in the umbilicals but we also added that that strength uh to provide that protection yeah and and the managing of that tether is extremely important because you know as they go out if it can get tangled up and you actually see Sarah there kind of moving around right it's it's very easy in in this environment where you're floating BX Dragon Eva off you complete who are in position to Eva nice cop Cur position but you saw Sarah kind of move the tether out of the way and the part of that is that's actually impacting go to command VX push a talk all seats C and so this will this will be one of the unique things about the spacewalk today it'll it'll feel familiar if you've ever if you watched some of Mike space walks the crew is going to go over to what's called is set go for contract ev1 contract ev2 contract support one contract two com SpaceX copies all good coms all four [Music] crew so essentially now all of our crew are on open mics they can all talk and hear each other and they can talk to the ground and so you're going to hear a lot more chatter start to pick up uh once we start the suit pressurization you're going to hear almost like a sound that's just the air starting to flow into their suits um how how loud does it get inside your suit it it actually is quite loud uh that air flow is just constantly which is a good thing right because not only is it providing you the oxygen but it's also helping get rid of that CO2 that you're breathing out so you want that air flow uh to be constantly going and and so you always are hearing that fan uh that that's uh making that happen and so that is that is certainly pretty important and the Box thing I got to say you know it's nice that you don't have to push a button when you're outside there to to talk Dragon SpaceX we about 90 seconds from E initiation got some fist bumps going on yeah and we just heard we about 90 seconds from Eva initiation so we should see them get the go to close their visors and then they're going to open up one of the O2 valves on their suits to start the suit Purge and that's going to be the official start of our space walk today so we're we'll get through the the final goes and then we'll see those visors get closed oxygen start flowing and we'll be off I love how everyone looks so calm and collected right now I think that's a a a great great visualization of just all the extensive training that they've gone through to get to this point this has been years in the making um I'm sure they're excited uh but everyone's focused it it is an interesting time right now right because one of the hardest parts I always found about Dragon SpaceX SpaceX is go for Space Walk operations report visor is down ready for secondary O2 flow initiation and crew is go for space verify your vience are [Music] secondary 825 is [Music] open and that you are go for the EVS ev1 is go ev2 is go support one is go support two is [Music] go Dragon Space X initiating secondary [Music] o02 and with that news our Eva has begun [Music] so you're you're going to hear referred to as primary and secondary O2 primary is going to be that primary flow of oxygen to pressurize secondary is largely putting oxygen into their suits to help with cooling but secondary is the first one we turn on and so our O2 flow timer has started Eva start at 3:12 a.m. Pacific I'll do the math on UTC in a little bit so this first this first operation or this first step in the operation is a suit Purge so inside their suit obviously when the visor is still open it's still a nitrox environment it's the same as the cabin uh and since they're going to be at a lower pressure than what you can basically live at with with oxygen levels um they're going to be on pure O2 they're going to be a 100% oxygen environment and I mean you guys were in the same thing and it's it's because like your suit can't you can't move a suit around at 14.7 PSI can you maybe you can they're like no that would be pretty that'd be pretty tough to do and and as we talked about earlier that's why that Mobility is so important because the when that suit is pressurized like that it it can be challenging to move around absolutely so here on your screen we can see the polaron crew now with their visors down the Eva has begun we are beginning to flow that uh O2 through now now we will of course bring these views to you as we have them but due to ground station coverage they do come in and out here and there um but every moment that we can we will certainly be sharing these with you um I also wanted to point out quickly that the the the window near kids feet was so much brighter than it was uh just even five minutes ago we're going to be seeing that uh in STK contrast as soon as we get uh the Eva with the hatch open and ev1 out there yeah it's it's kind of interesting you you you mentioned that because as you're going around the earth as fast as you are right in in 30 minutes or 45 minutes or so you can be passing in and out of that sun and and going into Shadow and and so that brings its challenges as as well because the temperature um can change pretty drastically just in those transitions from night to to Daylight and and so there's a there's a it's an interesting moment when you're passing through uh through that time that's actually one of uh the reasons that the visors have this new coating on them different than when you wore the a similar helmet um that coating actually helps to insulate the individual inside the suit so when they're looking at the sun dragon Space X a reminder after the initiation of primary O2 flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow [Music] initiation if you1 copy db2 copies Dragon Space X secondary flow Purge complete close secondary O2 valves and Report ready for suit [Music] pressurization ev1 closed ev2 closed Port one closed report two closed b x dragon is ready for SE pressurization initiating primary O2 this is normal this is with the airf flow coming through uh the crew members on Vox meaning uh that their their microphone is on the whole time so Sarah and Jared are going to be adjusting their audio levels um as this flow continues to to help regulate that yeah the the the Vox will kind of attenuate so it'll it'll sound like this now but as we get through The Space Walk it'll kind of come down and you'll just hear voice a little bit more clearly uh their their voices are actually going to change too like did that did that happen to you did that throw you Mike the first time you heard it absolutely did yeah cuz you're you're you're talking and you're going who is that right you don't realize how how much different it can sound um your voice can sound in that lower pressure environment yeah speaking of lower pressure we can uh we can see the pressure changing there with the Telemetry in the bottom left hand side of the screen so we can see that suit pressure going up um and we're able to keep tabs there um as well with the dragon pressure so Dragon uh on the far left Circle that's the pressure within the cabin and then suit obviously that's the pressure within the suits so we'll be actually be able to and I think we've kind of been able to see it already um that these suits will inflate a little bit um look a little different and we were talking about the the visors before so when they're in the sunlight that coating will help keep them cool and not overheat them and then when they're in Shadow it'll help keep them warm so uh and it's also like your sunglasses as well right serves that purpose all right so at this moment the suits are getting their primary pressurization this takes about 3 and 1/2 minutes a little bit less and then we're going to go through those actual suit leak checks I the crew will probably get a reminder they have to stay really still when we do those leak checks and I always was kind of wondering like why the heck and like if you if you bend your arms you're actually going to start you know changing the volume inside the suit that'll cause pressure spikes and so that's right you got to stay really still yep and then after after we get through the Lea checks we're going to go through kind of that final pre-breathe uh where they're going to hang out in that 100% O2 environment just to continue purging all of that excess nitrogen pressure stable Purge complete halfway secondary FL on report one complete e one open one open [Applause] open and right there there they they finished the purge and they did a quick uh reinitiation of that secondary flow check secondary flow and Portland complete give you want part one St T these handles that we see Jared holding on to these were one of the additions uh or uh customizations for this mission that we talked about ear support one facex contact we got you all right copy got Dragon effect beginning spe check evaluation and still check so once again that background noise is expected um that is the microphones and the flow of air uh within the suits so we're trying to stay quiet to uh along with you listen in on what the crew coms uh are as they go through um we're also uh going to get views in and out as we mentioned before due to uh ground station coverage and it is it is a little bit tough to hear we just heard though that we got four good leag checks on their suits and now they're going to be in this final suited pre-b so again this is going to last about 19 or so minutes uh and this is just to do kind of that final get all of the excess nitrogen out um and we started pre-breathe just two two hours after they got on orbit just like you know gradually lowering the pressure and I mean pre-breathe that that's something that kind of evolved over time with the space station where where were we when you were doing your space walk yeah so we were past the kind of the camp out phase of free breathe U but that's how we used to do it and it's very similar to what what the PO Don crew has been doing over the last couple of days we'd actually have uh astronauts stay inside the crew lock overnight at a lower pressure just like they did when they first got on orbit now we've moved on to we do it the day of it still is a long day we T start about 6 hours prior to going out the door uh but it's not 2 days prior it's worth noting uh along the lines of training and how the crew prepared for this mission that all four of our Polaris on crew members uh and some additional Polaris and SpaceX crew members actually went into um a a vacuum chamber and tested these suits out and spent uh a bit of time at lower pressure just to help learn what that feels like and get used to it well and I think the other thing that's important about that is it's real right it's it's the first time that you're in that suit and it's actually a vacuum around you right and there's just something mentally that I think is important to put people through those moments before actually have to experience the first time in space yep we we saw some of the unique ways we train the crew for this and I mean training for space station space walks I'm still really upset I never got in the pool that looks like one of the coolest like parts of being an astronaut is like not being in space but just doing some of this training yeah Dan I I I tell you I can still remember the first time I stuck my head underwater not in the in the soup but in the for diving but you can hear the calms of of everything that's going on through the water like that and it just gives me goosebumps to think about I think about that it was a really neat environment but it looks like these guys had a pretty neat way to train as well with the uh the the harness that would hoist them up and out and and all of that that's that's pretty impressive yeah um we definitely created some rigorous uh new training for the best we could simulate an Eva while still on Earth um with hoists and uh you know it was um it was a lot of fun to watch them train back on board with cameras in 3 minutes so our core just called out we'll get we'll get views back on board in about 3 minutes as Kate talked about earlier we're using ground stations for our video coverage all of our communication with the astronauts are through tedris so tracking a data relay satellites we have a little bit we'll have constant audio but that video we need those ground stations uh but right now they're just they're in that pre-breathe uh that final pre-breathe still we started our space walk about 13 minutes ago when we initiated O2 flow to the suits the time was 3:12 a.m. Pacific 12 1012 UTC I did some quick map took me took me 13 minutes to do it but I did it um so we're once they're through this pre- breath we're going to start getting into some really exciting parts of the spacewalk and and then after after we get to the pre-breathe we're going to get to cabin vents so you know what's what's go through your head when you're like man it's happening the A's going out it's really happening it's happening yeah I I I tell you it is a long process to get to this point right they've been prepping for this for 2 days right and and one of the hardest things I found about the space walks is the waiting hurry up and wait hurry up and wait right you are so ready to to go out and to do this Mission and and to go out that hatch and it just takes time and I think that's one of the things you talked about my fifth versus my first you're fifth you kind of understand how long it's going to take you have better appreciation for how long it's going to take and so you literally find yourself in these moments when when you're kind of waiting through this pre-breathe or you're waiting for the airlock to depressurize just kind of find yourself just floating there kind of zoning out trying to keep yourself calm and relaxed and and until that moment when it's it's game it's game time yeah now just a quick mention we about a minute out until we uh get those views back uh inside the cabin um The View that we had previously was our Dragon tracker which uh if you want to see where Dragon is you can actually look that up as well um we have it on our website spacex.com slf follow- Dragon um but yeah just as a reminder uh our our crew they are in their designated or well Jared's not but um the yeah um are our crew members basically Sarah and kid have switched their seats for the Eva um we saw we last time we were able to see inside the cabin we saw Jared awaiting um to open the hatch so he wasn't in his Commander seat but uh Sarah is now sitting in Scott's pilot seat also known as seat three um and then Anna is on the far left side and Scott is on the oh yeah we can see it there on the far on the far right side um and also just a reminder uh their their call signs for these Eva operations um Anna being support to kid being support one and then Sarah being ev2 and Jared ev1 representing uh that Jared will exit first uh do his activities which include just some Mobility testing of the suit uh and then Sarah will go out and perform the exact same uh testing once Jared comes in um meanwhile uh kid and Anna will function as the eyes and ears uh they will be performing uh their own uh list of operations during uh or their own list of tasks during the Eva so while Sarah and Jared are going to be the ones that are you know partially egressing the capsule once that uh forward uh door is open uh kid and uh Anna will also be performing in Eva in their own right that's right and we talked about it earlier first time four people exposed to the vacuum of space like that's there's a lot of first in this that's going to be a really cool first not just for us and dragon um but we are going to be getting views back really soon we're again just in that final pre-breathe step right now and then we're going to start venting uh venting Dragon down to near vacuum so we're going to have a couple of different valves that are going to open up and the atmosphere inside dragon is going to start going overboard out into the vacuum of space now the crew the ground they can control they can pause that cabin venting if they need to uh we can pause and resume the most likely reason is for ear Equalization is again you're you're going through a lot of pressure changes anytime you do a spacewalk and so if you've ever flown on an airplane and your ears popped you've experienced just a little bit of what they might be going through right now uh once we start cabin venting uh if we terminate or abort that the spacewalk during that venting we cannot start again we talked a little bit earlier about how consumables are like the thing that really drives you uh and for us we don't have a great big airlock with this with you know a full station worth of oxygen and stuff like that um so complete confirm rting at prev complete1 go copy initiating Caron venting there we go that is great news so uh that breathing of incre a pre-breathe where they were breathing increased oxygen we just heard that uh they're good they all all four crew members gave the go uh so now we're going to vent the cabin yeah in in total this will take in total this will take about 8 minutes and you can this the graphics you see in your screen that's live Telemetry everybody so you can see the pressure inside Dragon starting to tick down you're going to see the suit pressure tick down as well is what we're really trying to maintain is a pressure differential and so with these suits we're going to be hovering right around five or so you might see about 4.9 to 5.1 5.2 um it'll be about 4.9 and then we'll probably see it go up a little bit uh when they reinitiate the secondary flow cop seven yeah Dan and you talked about that about five PSIs what the suit will be we're actually a little bit lower in the Emu and so we've talked a lot about Mobility that difference between we're at 4.2 and they're going to be at five it can actually make quite a bit of difference just in how hard it can be to move the suit around Etc yeah this crew got to and that's something we can simulate you know on in a vacuum chamber or even just uh in 14.7 you can you can simulate that that differential pressure getting calls from the crew they're they're monitoring along1 P we're going to hear that kind of we're going to hear that chorus pretty frequently where you do those kind of frequent most like checkins and I know you guys did something kind of similar where like you wouldd have to pause and you know check your gloves that kind of stuff we we did I I will tell you one of the interesting things watching this uh live right now the difference is how quickly the depressurization is happening here versus uh what my experience was and and so you talked about being able to clear your ears and all that you're not giving a lot of time for your you're not giv a lot of time for your your ears to adapt to that lower pressure so this this is seems pretty quick to me yeah break breaking new ground with this new suits new operations for everything we're at about 4.5 we're going to see that tick down it's going to get down to just under 1 and it's not going to go all the way down um and then what we'll actually see is we've got a capability to open the hatch automatically we got a motor in it um but Jared's actually going to unlatch it and he's going to give it a little tub to kind of break the seal breaks any of the kind of the stion in the hatch itself and that's going to kind of take the capsule down to its final vent before Sarah who's at the displays she's going to command the hatch to actually open um yeah that's a good point and you know there's there will be slightly more pressure inside the capsule so really just helping PSI look good copy four so Jared really can't open the hatch all in one fluid motion so we will see him uh release that that pressure slightly um before being able to open it completely and I think one of the important things you guys I think had talked earlier about you put some more um restraint devices inside the capsule from when I flew on it and that's extremely important because there's going to be force that Jared's going to have to be pulling down on and he needs to be able to Anchor his feet somehow um otherwise he's going to pull and it's not going to go anywhere and so the the new restraint devices in there we're going to see how important that's going to become here when he tries to open that hatch yeah yeah that's that's one of the things that's why we have Skywalker out there we've we've talked about how kind of similar to to Gemini when they were first kind of stressing their legs but important to remember we've got that 50 or 60 years of space flight history that we're able to draw these are new suits this is a new operation this is to you know work out all the Kinks and really test this for the first time but we're going into this with a whole lot more information than they had back then we know you need handrails it's going to get real hard real quick that's right that's right yep we did we did also hear uh dragon's moving into its uh its Eva orientation essentially we're going to point the trunk at the sun under 3 PSI I think it's also interesting you notice that the de pressurization has slowed down a little bit right so as we get to this lower pressure it's it's just taking it longer for that remaining little bit of air to to uh go out through the vents an ev1 come Che ev1 M clear mad clear as well now also hear the Vox starting to adjust its levels that that flow of oxygen has not stopped but the microphone's kind of adjusted and it's getting a little bit clearer and yeah keep keep an ear out you might hear their voices start to like tener down a little bit I do think that's a an important Point Dan that how important Comm is yeah right and and when it's compromised a little bit just by that extra air flow Flow In The Box not keeping up with it right away uh how challenging it was just to hear those calls and they can be some pretty important calls so uh C is is just critical we can see Dragon capsule now approaching close to two psia like Dan mentioned earlier that's going to get to just under one it's incredible to think that uh you know the Dragon capsule in all of its power and glory and awesomeness the the new capsule is around their bodies right that that is what is going to protect them um from the vacuum of space and uh you know just seeing how even though it's puffed up and we know that it's uh you know holding that pressure it still looks so cool for lack of a better [Music] word you de yeah you really have four mini space or uh spip in there pressing PSI guess that means we have four aliens in there too that's right Dragon SpaceX L than 1 psi from hatch operating pressure we have a tedious Handover in 2 minutes we are going to wait until after the teacher hand over to command in Hatch open [Music] prep one copy yeah I think you heard that the the tedris Handover so there's going to be a a short period of time there where they're out of Comm and we're at it's kind of interesting because we're at a very critical phase ah as well and so you want to make sure you have all the data and uh and the ability to talk to the astronauts before you actually take that next critical step we'll see it we we're seeing that pressure continue to take down Dragon originally designed to be able to still operate in a vacuum that was some of the emergency situations I know you train for Mike we did make some modifications to this one uh to essentially turn Dragon into a functional airlock um we added some additional uh vent paths um we do use like some of the same ones that you guys Ed to like pressurize the vestule and stuff like that um that are actually in the hatch but we've got a we've got an extra one in there to to be to essentially do that deess as quickly as we did uh but we're going to we're going to see that get down to a little under one and then we're going to see Jared kind of jump into action he's going to unlatch the hatch and then he's going to give it a little pull to break the initial stion and then we're going to be able to uh see sarah. psia all s look good one C that's one thing to note that while we have been progressing through this pretty quickly we did have the capability to pause if any of the four crew members needed to uh you know take a moment to you know let their ears um come to equilibrium or just kind of get comfortable again um we did have that option but everything has been going really well so far we haven't had uh to to pause cabin venting and if you're just tuning in heck of a time to do it we're about a little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of these crew members that was at 312 Pacific 1012 UTC we did heard that dragon's now in its Eva attitude complete so again we've got we've got dragon's trunk pointing towards the than you on board watching through the cross [Music] view that was SpaceX core Arthur baralt just letting the crew know uh that we're the cameras are on inside and uh basically which camera is is looking at them it's it's so fun to hear Arthur's voice because he was actually a part of our mission as well in fact Arthur was an intern started out as an intern when we were first uh starting the training and and so now to see him as a as a core and uh is is pretty neat very similar to Sarah who also started as an intern yes [Music] yeah right we're coming up on one PSI you might see you saw the light change a little bit through that window is we're in our Eva position trunk facing the sun that's going to help us with thermal uh inside the capsule and on the creu suits also going to make sure we're maintaining that uh that optimal pointing for communications with the tedris satellites uh once the hatch is open we're going to disable any of the Draco thrusters that point forward is you know want thrusters firing off when a crep members outside [Music] we at one you can see the suit pressure is ticked down too there's about 4.7 difference between the suit uh and the ambient cabin there in dragon that umbilical that you see there uh just to the side of Jared that will continue to flow the air into his suit as well as provide Telemetry and Communications connection that's also where we have the um safety harness built in as well so it's able to SpaceX cab pressure below hatch operating limit standby for transition to hatch open prep here we go Mike did you get to open the hatch I did you did yes yeah when you when you go out as uh G hatch open Dragon SpaceX for hatch open prep confirm K to open [Music] hatch that is great new [Music] open SpaceX copies drag you are go to open hatch go excited go to open the hatch Mike as you mentioned before that continuous communication hat handle as you can hear we do have a crowd Gathering outside of Mission Control uh here in hawthor in their excitement somebody dropped a cup we can see our commander Jared isaacman now turning the crank which allows the uh that top hatch to open we'll see him give it uh a pretty heavy uh1 hatches visually indicated [Music] open space copies stand [Music] by should see him give that hatch a pretty strong jolt to release that stion [Music] hatch is now [Music] unlatched Mike talked about he's we see him getting his feet getting his feet set that's right Dan You' asked if I got open in the hatch so when you go out a zv1 just like Jared here is ev1 that's that's typically the role for for you is to open that hatch and you guys have to draw straws fever get it's exciting it is it's very exciting yeah now for those of you that have just recently joined as you can see we have successfully depressed pressurize the Dragon capsule uh down to Zer psia you see that in the bottom left hand side bottom left corner of your screen um our four polaron crew members um have uh gone through the uh O2 flow and we see Commander Jared um isaacman now standing by uh to open that top hatch the nose cone is already open it opened just shortly after uh the crew got into orbit uh so Dragon Space X Target pressure [Music] reached SpaceX I'm on seting the hatch [Music] now Jared now opening Dragon resilience into space so we saw some motion on the hatch again he's just giving it kind of that initial tug and then Sarah gets the push the button to swing that hatch [Music] open much more movement there on the forward [Music] hatch this must be pretty exciting for Jared because that center part of dragon space6 that's a good brace we're going to have you repeat the operation center of the hatch actually has a window the hatch is unseated copy give it another call hatches sever in copy we see [Music] it looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes Dron space xent complete ev1 return to seat [Music] then e one copy transitioning back under the [Music] display so again one of the reasons we had Jared do that was to Dragon SpaceX we're actually watching that hatch we're going to have you repeat the last operation sounds like they're going to have him repeat him one of the reasons we're doing that is just to kind of vent any of that residual atmosphere back from under this way and ev1 you are go for manual hatch [Music] open sounds like we got our first audible of the day as we said that we can open the hatch opening the hatch we could open the hatch man we could open the hatch automatically or we can do it manually and so they just gave Jared the go to open that hatch manually so we we just went out of ground station reach so we'll get the views back [Music] W we'll get the views back real shortly uh and then the the hatch will get hatch open and hopefully we see it yeah hopefully we see a hatch open hatch is open t copies hatch [Music] open that is fantastic news uh for those that1 I'm looking at for seals initial view looks pretty good I don't see any VES or ination copy on hat kill [Music] report yeah that seal that you just heard him talking about it's such a important part for the end of the Eva right so that when they close that hatch again you get a good open get a good SE SpaceX can you command open forward hatch we going to stall it open there is our first view of the forward hatch wide open space [Music] if you just jumped in we are 38 minutes into today's spacewalk and the hatch is open on Dragon first view from a helmet cam looking out Dragon SpaceX we see installed ev1 is go to continue that structure you see there is check for er1 I'm transitioning back from under the displ SpaceX copies we with you in your helmet cam once again this helmet cam what we that structure we see is the the space walker this is Jared now egressing through the forward hatch of dragon [Music] resilience the first views of the first ever commercial spacewalk I'm at the bottom of the mobility progressing I have a feeling the crowd is about to go wild there f back at home we all have a lot of work to do but from year bir sure looks like a perfect [Music] Road even one going to step into Matrix One singlehanded Mobility demonstration Commander Jared Isaac men now emerging Matrix one watching from the nose cone up down left and right are [Music] three pitch and roller three y a two switching single-handed operations ref fine static and with Dynamic disturbance switching to left hand [Music] up down left and right are threes maybe a two ditches a four roll is a two Y is two so these are the suit Mobility checks that Jared is single operations dynamic in with disturbance are all adequate test Matrix one complete Hut check 5.3 PSI 48% RH 33 deal 9 CSI SpaceX copies test Matrix 1 and HUD read out true op one's good one good good okay stepping into vertical translation we're going to start with the horizontal bars all right we're going to transition over to Vertical i' say vertical and horizontal are equally workable slightly favors horizontal I'm going to do a Max reach left hands at the top of the mobility a at the midpoint you have good video we just lost our live video We Stand by one okay Switching over to Max reach switching I'm holding up at the max any1 go ahead and continue the operation uh we'll let you know we're back on with live video C that and for your awareness Max reach L8 and the mid bar ma test Matrix 2 is complete C read out 5.3 PSI 33 decimal 9 Celsius % RH copy test Matrix complete and hard read up check E1 good stepping in the test Matrix three three demonstration ev1 Space X for Ingress [Music] time go Space X recommended Ingress time of 02 flow plus 4 7 minutes copy that in Time 4 7 minutes and dragon we're back on live video from the noon happy night SP [Music] and space at TV1 I would say the handsfree demonstration is very comparable for the trainer in terms of the foot restraint SpaceX copies and ev1 when you have time if you'd like to return to the reach demonstration uh we'll take a look at that with the live video Happ that test Matrix 3 is complete the Hut readout is 5.3 PSI 47% R 33 deal 8 CSI and stepping back into max reach copy test Matrix see stop of the mobility Aid and uh let's get a Quick Crew off check e want good good I'm good happy that okay uh matx reach it's left or right hand seems to be about the same top of the mobility Aid and then the midr we see it Che up from the [Music] bottom any go back SpaceX negative we got about 1 minute until ev1 [Music] Ingress 1 minute this gorgeous [Music] you want to ADV you get R right E1 we're checking out your helmet cam [Music] now now I'm checking out your nose con right now and looks pretty good cop we're cing those see you looking at [Music] us all right we're coming up about that 02 F timer time two check for ingr E1 good e all right St ja e one that's for the huge team effort that have suppos to get us to this point we know it's just to start and I'm transitioning back into the vehicle [Music] [Music] [Music] face at TV1 we taking a quick look here the Hat field from what I can see so far they look pretty good copy on the hatch seals and stand by for transition to read off reset got St and ev1 is clear all right so Jared back inside uh we we heard him going through What's called the test Matrix uh it's basically just a bunch of Maneuvers using different hands using the foot Mobility offet is in progress calling out numbers right now though we're doing you just heard cop Arthur call up three off resets so we didn't use any of the forward thrusters while Jared was out there we're re-enabling them putting us back in our perfect ad attitude before Sarah gets ready to go out the door fun thing to note it's still not a perfect vacuum inside a dragon is it's an open loop system so oxygen is kind of getting dumped into the cabin as this is going on so you got a higher pressure in Dragon than you have outside so we're not worried about Thruster pluming yeah now you mentioned Sarah um just like Jared she will have 10 to 15 minutes uh outside perform those same sets of Mobility tests as Jared uh like we heard the core do um with ev1 uh they will call out when there's one minute remaining uh attitude reset complete ev2 go for erress there is Sarah's clear to crew Che for ev2 Eos ev1's good ev's good good two good Ed is going to go stand on the door and then step outside now this test Matrix that uh Jared just performed and the one that Sarah's about to perform they have both committed to memory um in order to execute these um we saw it being done pretty efficiently I can't believe how quickly that time went by Mike we were talking about how your Spice Box were hours and these guys only have 10 to 15 minutes and it just like that yeah it it can go pretty quick and uh but fortunately um what good I see a little bit of a bulge between 14 and [Music] 13 so you're hearing Sarah call out some more the seal check there as as she's exiting out 3 Fe SpaceX copies that report good fix so this was something we knew might happen um and between 28 and 27 copy the crew trained on exactly what to do in this scenario just pop it back in one final between 19 and [Music] 18 that might be best we get hatch closer SpaceX copies can you repeat the location EV [Music] complete between 19 and 18 all right copy I'll track that and uh ask again when you're Ingress cppy edq is proing with e super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her space walk ev1 I'm going to hand this back [Music] here like we mentioned Sarah will be performing the same uh set of Mobility tests uh so we will do the same uh try to stand by and listen to this [Music] I mean I said it before a lot of us work here CU we want to do this all right stepping into T Matrix one for single-handed Mobility really cool to see one of our on out there that's [Music] awesome and ev2 for awareness we're watching from the nose conon Cy all I just say in all three transation aess I'm having certainly cross Pur movement forward back I'm ining the bit other roll s it's left right and up down a bit of a ktch but all achievable rating is three now the [Music] three four [Music] and PES the food [Music] for for left man stepping into vertical translation SpaceX copies and ev2 for awareness we're tracking an Ingress time at O2 flow 59 minutes happy 59 minutes horizontal bars are definitely preferred and iately able to fatalize my body with single hand disturbances F night stepping into M reach do you have visual a firm we have visual on the nose cone copy from bar four to Bar two from top down and S more reach from bar two up to Bar four SpaceX copies reach and test one conce seat pressure 5.25 33.8 Celsius 37% humidity SpaceX copies HUD readout and test makers one complete Cy 7 p62 like we mentioned before views going in and out doing during excuse me due to those ground station uh coverage gaps yeah we we com some of the same coms are through satellites but we've got ground stations for video on dragon as you can see in the tracker we just flew over on New Zealand we're about to go right over the middle of the Pacific no ground stations in the middle of the are actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got she got about a minute left and then she's going to start heading inside and and see if with a little more work I can actually get between almost bar one and bar four on that stre space has copies and you could see the Earth dark and we flew into like an orbital and test Matrix to try to combine them so we'll call that con he pressure 5.27 38% humidity 33.7 cius SpaceX copies Matrix complete and huded out stepping into handre demo are able to engage and disengage my feet copy that D2 and once you are able to engage disengage we'll actually have you start Ingress we're just over 59 minutes O2 flow poy [Music] that sitting up check for IND good good cppy coming on in all right and just like that Sarah's going to start making her way in dark here check those hat seals again SpaceX copies on Striker plates and ev2 I have one more ask for the hatch if you can uh check out it as well when ready to copy [Music] ready copy copy and ev2 what I'll have you do is when you Ingress can you get eyes on the hatch handle mechanism and see if the handle has been stowed in the Do Not Stow uh window and report if you can see that check I think it's just outside copy just outside thank you just outside the range and for awareness I do see a couple of those same points folding again between 12 and 13 copy your go no mostly between 12 and 13 right now space X copies at 12 uh if you can you're go to address those Cy [Music] in these numbers being called out represent the location [Music] around yeah the location around the circular hatch just identifying where these bulges are so Sarah is now reing that seal not quite able to reach the bathroom so we'll proceed with clearing for hat closure just like that we're already hearing about hatch closure it's incredible that these two Evas just in two blinks of the eyes are uh is on your screen there is SpaceX core uh or crew operations and resource engineer on duty tonight is Arthur baralt this is the uh the voice to the crew throughout uh their operations of course you know everyone has to sleep so we have different shifts for core um but Mike your time and dragon driving close you're good Cy the [Music] handle let F and forth I'm [Music] cling once we get ground station coverage uh again we will be sure to bring you views within the Dragon capsule but right now Sarah is closing the forward hatch it sounds like we might give the motor a try he confirmed the hatch is visually indicating closed command hatch is verified last hey commanding Eva hatch [Music] Clos Eva hatch closed all Dr go enabled Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress one and E1 copy everyone check secondary O2 valve closed C four one I'm good d1's close 82 CL one two [Applause] close so a couple of real big moments right there Sarah was able to make surey second FL is closed and agree evess one she was able to make sure that the seals were in good spot we got the hatch closed you can see of a half PSI for 8.3 see the pressure starting to take up just a final confirmation everyone confirm secondary O2 Val are closed keep1 Clos closed 14 h g and we're through one for 8.3 all right so each of the crew just closed those secondary O2 valves on their umbilicals again that was primarily for cooling um during the space walk itself suit still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon uh right after they get the hatch closed they're able to do kind of an initial pressure check cuz again oxygen it's an open loop system with these suits still flowing into the cabin you're able to see positive pressure response showing that the cabin uh the hatch was closed and was sealed uh we'll still do a leak check on our way kind of back up to our nominal cabin pressure um so we're going to continue ticking up until we're about 8.3 PSI and then we're going to transition into the second phase of our repress um really the difference between repress one repress two is how frequently we're injecting atmosphere uh as kind of the the repress is also pretty unique with dragon um we're repressurizing with just nitrogen right now um which is a little bit unique obviously you have nitrogen and oxygen in your atmosphere uh with this we have O2 flowing into the cabin through the suits so we only need to add nitrogen so we're able to just basically add a bunch of that to really start getting your pressure up O2 continues to flow into the cabin through the suits and we're going to continue pressurizing until we're pretty much right back at our 14 right about a 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want want to make sure the crew takes helmets off and everything that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is m gravity everything's harder everything's on hard mode um and you don't just have natural convection so like I mean space station I think I've heard it a bunch of times Mike like you just constant noise of fans that's right almost yeah there's uh you've got to continually recycle that air um and one to help get rid of the CO2 right because as they're taking in that oxygen they're breathing out the CO2 and we need to to get that out of the system which is another important reason to have that air constantly circulating yeah um man that felt really quick that it did that was that was that was really cool to to see them outside for the first time and there they were what they were actually doing out there is a bunch of pretty simple tests as it looked but like this is just learning how the heck do you move cuz like just moving around yeah in micro gravity is tough it is tough Dragon Space X we're about 2 and a half minutes from tedra hand over around when you're in your short sleeves like we're in inside the capsule and when you put on that space suit uh it it's much more challenging to to move around with that on yeah and what they were really doing was just kind of like you put your hand on on Skywalker and then you're changing your pitch you're doing translation up and down and everything and then the one that I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah I think one of the other things I thought was interesting is you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab onto or utilize versus the vertical one so simple things like that you know for us it not a big deal yeah uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that you'd be able to share with us throughout this's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all of SpaceX and and really for for Humanity because it's just one of those small steps that's taken us that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime exent all right good to see you Hopper thanks bye all right so repress is continuing we're a little over 4 PSI right now again we're going to keep that going up until we're a little over 8 and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole process like right after we got on orbit yeah it was almost like we we launched them and gave them 2 seconds to acclimate and enjoy their cute zerog indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and uh let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there in the the tedris in and out so like we'll get it back but um so yeah just the fact that the uh all four crew members were able to just go right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during you want did you we're good you good just heard a quick check-in from them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at eight and then we'll let it hang out there for a couple of minutes uh Let The Thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressure is starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for 1 hour and 13 minutes um it flew by so so quickly um six on cabin pressure approaching one PSI on P2 I'm I'm sure for shared and Sarah flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clocks going to continue to count until we hear the call for Eva uh operations complete from our core Arthur burial that's going to come uh once we are done with the repress repress operation uh we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the P2 environment in the suit using Nitro before they get out Nitro being that same air mixture that you have in your scuba tank uh if you got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there we're just going to keep ping out should hopefully be getting video back from ground stations standby for transition to ress 2 at 8 decimal 3 and copy that SpaceX we're following along refres two at 8.3 and so once we transition to repress 2 once we're at about 8.3 PSI will stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we we' got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hopefully just about a minute and a half or so away from ground station so might get those views back inside a dragon I yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh PA refes to scw up Che e1's good good and yeah that Cals we're hearing a half PS side before we get to Le check monitoring check at 9 PSI the continual checks with all four crew members to make sure that everyone is good um if the answer to one of those checks was no there would be an option in this repress sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depressurize now this repress seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to tick up but we're going to pause at 9: we're going to do another cabin leak check so we should hear that momentarily time you we press two stop Dr space with you in Eva repress to stop waiting 5 minutes for theral stabilization we're St that St effect we're tracking appr your awareness we do a positive refres R we are 30 seconds into the reck like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness PPO one decimal 35 halfway there Su are still flowing that oxygen um and in a few minutes we will begin to flow we'll do a flush uh of of nitrs uh into the suits [Applause] all right we got our views back there they are it's a little sad to see that forward hatch closed again it's it's got to be really hard when they tell you it's time to go back in just one more minute yep reminds me of when I was a kid swimming in the pool you know time to get out just one more minute I mean it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline 8 Minute Le throughout show good good what you good cp2 just passed 1.5 we're a couple minutes into our leak check you're you're seeing the pressure continue to tick up we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that is why you're going to continue to see the pressure tick up you heard Jared call out the P2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14.4 or so and I mean that's that's a little bit lower than what we're walking around in now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that nitrox uh that K was talking about uh that takes them out of that pure oxygen environment and that's one of the final steps before we'll he hear that call from Arthur evva operations complete and that's when our clock's going to stop uh our space walk did start today at here at SpaceX in Hawthorne California and I'm Dan huitt from the communications team now the first Eva in history was performed in 1965 by Soviet Cosmonaut Alexi leonov followed just three months later by the first American spacewalk done by Ed White during the Gemini 4 Mission from those humble beginnings to walking on the surface of the Moon repairing satellites building space stations in orbit space walks are really a core component of human space space flight while Evas are wellestablished procedures for NASA and other space agencies this will be the first Space Walk using commercially developed hardware and procedures and spacex's brand new Eva suits which we debuted earlier this year now we've tested extensively in vacuum Chambers here on Earth but this is the first time that the suits will encounter the vacuum of space and on board the dragon spacecraft right now is the Polaris Dawn crew starting off you got Mission Commander Jared Rook isaacman Mission pilot Scott kid potit and for the first time ever we're excited about this to SpaceX employees Mission specialist Sarah Cooper Gillis and Anna Walker Menan who's serving as the mission specialist and medical officer for members of the crew have been orbiting Earth for 2 days since they lifted off from launch complex 39a at Kennedy Space Center on Tuesday September 10th it adds up to about 15 to 16 orbits around the Earth every single day in County on day two of the mission as you can see there on your screen Dragon fired its forward Draco bulkhead thrusters to send the spacecraft soaring higher than any dragon mission to date reaching the highest Earth orbit ever flown the crew uh topped out at more than 1,400 km breaking the record set by gmany 11 a half century ago when that spacecraft reached 13 excuse me 1,373 kilm this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 since that time dragon has gradually lowered its apog or the highest point in its orbit as the crew got ready for the space walk today they started to Dawn or put on their Eva suits just a little bit of time ago and they've been undergoing a process called pre-breathing where the atmospheric pressure inside dragon is slowly decreased and oxygen is increased to prepare their bodies for the Eva suit environment we're going to dive more into the oper ation of the space walk a little bit later and we're going to be hearing in live communications with the crew throughout so be sure to listen in as those happen yeah it's going to be super exciting to hear that and as far as views goes we'll have dragon's regular internal cameras that we have seen before and up to three external cameras one aimed at the hatch uh kind of like what you see there uh one on Dragon's nose cone uh which actually is the one that's there that's the the the camera on the nose cone and one on the newest piece of Hardware that you see there in that view we that is the Skywalker um which we will come back to shortly we may also have helmet cameras that will give us a firstperson view from the crew which will be incredible now since we are not using starlink to uh enable views today there will be moments of expected loss of signal due to ground station coverage so those views may be interrupted from time to time but generally we expect to get some great shots today and as of right now we're less than an hour away from the start of the Eva for now though let's learn a little bit more about the mission and our crew the Polaris program is a first ofit kind effort to rapidly Advance human space flight capabilities while continuing to raise funds and awareness for important causes down here on Earth today's goal is to demonstrate critical operational capabilities that are going to serve as those building blocks to help further human space exploration player Dawn Mission has a lot of first time objective so the Polaris program chose a crew of experts who know each other so they can tackle this mission's challenges as a team first up Mission Commander Jared Rook isaacman also served as the commander of inspiration 4 the world's first all civilian mission to space Jared holds several world records including two speed around the world flights in 2008 and 2009 for the Make A Wish Foundation he has flown in over 100 air shows as part of the Black Diamond jet team dedicating every performance to charitable causes in 2011 Jared co-founded what would become the world's largest private Air Force dren International and that trains Pilots for the US armed forces in addition to his role as CEO of Shift 4 Jared is an accomplished pilot and astronaut with over 7,000 flight hours next up Mission pilot Scott kid potit who served as the mission director of inspiration 4 and he goes by the nickname kid which is also his call sign he's a retired US Air Force Lieutenant Colonel kids served for 20 years in roles that included commander of the 64th aggressor Squadron Thunderbird number four demonstration pilot US Air Force weapon school graduate operational test and evaluation pilot and flight examiner he's a command pilot with over 3,200 flying hours logged over 400 hours of combat time and following his Air Force career kid served in various roles including vice president of strategy at Shift 4 Mission specialist Sarah Cooper Gillis is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew one missions and most recently directly trained the inspiration four astronauts Sarah is an experienced mission control operator who has supported real-time operations for Dragons cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for human space flight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program full-time and capping off the Polaris Dawn crew mission specialist and medical officer Anna Walker Menan who serves as a lead space operations engineer here at SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragon's crew capabilities and developed critical operational responses to vehicle emergencies prior to SpaceX Anna worked for seven years at Nasa as a biomedical flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going into space that's clear but let's say take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isman I'm Scott kid potit I'm Sarah Gillis and I'm Anna Menan and we're the players Don crew I Love This Crew I mean all of them are just so hardworking so smart kid potin over here is our mission pilot talk about a career in the Air Force doing every job as a pilot that that anyone would aspire to achieve and having somebody who has you know been there for and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always [Music] there glue glue you are always there predicting what every person needs um and he's needy what our commander Jared I think he is incredibly sharp that's right something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical confidence we don't get out of any engineering update or brief or go through a procedure or debrief without getting into the weeds and making sure tea is crossed every eye is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared that served her in her role as core it served her in her role as a trainer Anna you have this incredible joy that you bring to everyday life it is infectious it makes do all smile feels like she always has this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then as a biomedical engineer and a background like that inspires like a ton of confidence that you go up there if uh people aren't feeling right that she's going to be there to take care of I cherish all the moments that we've had uh in these experiences and uh we're just so excited to to go to space now that you know a little more about the Polaris Dawn crew let's recap the mission so far and what's coming up next since liftoff and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours demonstrating the Eva suit's pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I'm mentioned earlier on day two dragon proceeded to a high apogee of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the spacewalk dragon has been executing a series of a apog loing apog lowering phasing Burns by now dragon has lowered itself from the highest apogee of the mission of more than 1,400 km to about 100 0 by 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude Children's Research Hospital um and they they're joined Live While polaron crew member Anna Menan read from her new book kisses from space along with the patients and families at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the poist daon crew Enlisted the help of Childhood cancer survivor live to create the mission's zg indicator while not a St Jude patient herself Liv met the inspiration for crew and inspired by the mission of St Jude she agreed to share her talent to support Polaris Dawn is Li and I spell it l and then I drifty mark exclamation mark I can tell you anything about space from the miles from Earth to the Sun to every Mission basically I had cancer in 2021 cancer survivor like Haley I really have a passion for wanting to help St Jude and other kids who have those struggles as I had so I first met Liv a couple days after I got back from space at our Splashdown party and I got to meet her family and they told me about her journey that she was on I remember that she gave me a card she had written and it said thank you for helping other kids with cancer like me I hope to go to space like you someday and my eyes just filled with tears whenever I read that basically my one passion is to um be the first child in space Liv was really close with the players Don crew and they asked her to design the zg indicator a zerg indicator is like a little plush toy that floats in the air it basically shows that you're in your they kind of hide it over in the corner and then once you hit the g it'll float up and reveal itself my main idea for asteroid is based on ean's dog POI I've always loved sheats they've always been really cute and then when I heard Ean got POI I was like done I love them I want asteroid to be for every child and help them see oh restro went to space and I can't I can achieve my dreams we are also flying Liv's original drawing that you see there that was used to design the Zerg indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital all donations from the sale of asteroid will will be General donations to St Jude the inspiration 4 Mission helped raise more than $240 million for St Jude Children's Research Hospital and polaron will continue to raise funds and awareness for St Jude while partnering with the organization to provide Healthcare in underserved communities around the world now if you want your very own asteroid they are available at shop. spacex.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the way so be sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got I snagged one I got in there I got a kid who nice needs one yeah all right now the first phase of the spacewalk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre-breathe process started that's when the oxygen levels started to increase incrementally as actual the cabin pressure inside Dragon was started to get incrementally lower the pre-breathe process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any space walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure de of in deep water back up to the surface and to do all this dragon's just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in in the suit during the space walk itself they've got the ability to pause the process if they experience any discomfort but the ear ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude in an airplane um all four astronauts are going to be suited for the spacewalk today cuz Dragon does not have an air lock that's also kind of why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with the stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah are just going to be lightly secured ahead of the spacewalk since they're going to be moving around and eventually heading outside as we listen into comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support two is Anna again they will not exit the Dragon during the Eva but make no mistake they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rotate those upright during the Eva just to give more room to move about after that seat rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tap in the health of their suits and they'll get some other stats of their suit operation during The Space Walk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations brief from the SpaceX team the crew will announce their go noo status and then it'll be time for the spacewalk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the crew suits until we complete the repressurization of the cabin and just prior to we get to cabin venting pure Oxygen's going to start flowing to the cruise suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the sun this will help keep temperatures Communications and space C power stable during The Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during the spacewalk he's going to be the first to exit the spacecraft he's going to go outside and he's going to do a series of Mobility tests these are kind of the core component of the spacewalk today he's going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into Dragon after that e to or Sarah will step out into space to perform the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit then after she's completed her test Sarah will stand by near the hatch for the actual closing and then at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is suited up and awaiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the Space Walk and before we get there there we're going to span the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back here in Hawthorne with you tonight on this uh very memorable night for sure yeah absolutely uh now Evas may be new to SpaceX but uh you have participated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two missions you know the first one was back in 2013 and I uh I went up on a Russian soy use and on that one we had two space walks and the interesting thing about those space walks is they weren't planned uh they were what we yeah they were a big surprise for us uh contingency spacewalk and of course surprises happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a space walk as everybody was getting ready to celebrate Christmas just helping deliver presents that's right that's right and then your first play was on the so but your second one you were the commander of crew one I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than anybody cuz you you actually got to call at home while you were docked up there that's right it I me I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was a great amazing group of people not only uh uh Victor Shannon and suichi but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough crew stations and actually you can see a picture of uh of where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the station where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the spa get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for a crew one weren't they they were yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees and somebody else getting to uh getting to test them all the time so so yeah it was pretty neat to to get to see that switching it up a little bit cuz we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to, 1400 kilomet uh we like to talk about something called the overview effect so kind of that first that oh and we're getting some coms from our crew too yeah nice spaceex dragon ready check C kid H me got you loud and clear dolphing continues andless though just going to be right C cover that kid make that dony all right some some quick com checks we heard kid that Scott po he's going to be one of the support crew in there today so our our first calms down uh as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back and I mean you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overv effect is definitely real but when I first got the space um on that on that soy use uh how many years ago almost 9 years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now this feel really that's pretty but oh no um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you'll hear people talking about that that small sliver of atmosphere and you you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me a lot of questions and made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it brought as many questions as it did answers wow a bunch of bunch more trips then right that's right that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank White originally coined the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habitable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moonrise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to Mars and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of SP seat four is next support two is next and then ev1 and two are surely [Music] behind on that crew status get that c Quick Crew status from kid H yeah I I think I speak for a lot of space exors we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dragon and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean space walks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first space walk a contingency we had a failure and so sometimes when we're going outside it's it's not planned and you have a component that that is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out and we're putting a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar rays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Don crew is going to do today and you're just checking out the suits and checking out the equipment that that you're going to use in future space walks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or a achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um basic for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction requiredby actually uh if I can I'm just going jump in on that that's actually a very important call that was made you heard him say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around at what was that and so you heard them give them a warning that we're going to turn on some fans yeah and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those spacewalks where I was uh at you know outside and and what are you proud of you're you know it's it takes so much to put these vehicles up in the space and and so when you go out on the spacewalks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because uh people are depending on you and couple people watching over your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good station's back up 100% just like okay that's that feels great Dragon Space X our fan commanding is now [Music] complete all right hopefully no surprise sounds in there form so I mean as spacewalks are something that you you train the heck out of they're they're playing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a space walk yeah so I mean one of the first Chen Alles that you're always worried about is the how your suits functioning right cuz that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground are monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between you and the and the ground and so they're making all of those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about space walks that uh maybe people don't realize is you know you focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they these space walks um they they you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk no it never felt like a cew walk at at all um you know because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely um very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on you're more familiar maybe is a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I will equate a little bit of of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all of that kind of nervous energy because you're getting ready to go mhm well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on seat rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them up right that's just going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is spacex's 14th human space flight Mission since 2020 when Dragon became the first private spacecraft to take humans to the International Space Station it's also the first private spacecraft to take an all civilian crew to orbit during the inspiration 4 Mission in 2021 and just prior to Polaris Dawn Dragon completed 46 launches 13 of those are human space flight missions and it's since flown 50 astronauts representing 14 different countries throughout all of those missions dragon has helped support more than 1,000 EXP experiments in space pretty incredible stats there um and even from low earth orbit dragon is helping lay the groundwork for deep space exploration through missions like inspiration 4 and Polaris Dawn we are rapidly expanding our knowledge of how humans will adapt live and work in space designed to be here horizontal rail versus the vertical and how much easier that was for her to grab onto or utilize versus the vertical one so simple things like that you know for us it not a big deal yeah uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that You' be able to share with us uh throughout this morning's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all the SpaceX and really for for Humanity because it's just one of those small steps that's taking us that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime excellent all right good to see you Hopper thanks bye all right so repress is continuing we're a little over 4 PSI right now again we're going to keep that going up until we're a little over 8 and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that out atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole process like right after we got on orbit yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their cute zero g indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there coming inting the the tedris in and out so like we'll get it back but um so yeah just the fact that the uh all four crew members were able to just go right right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during you're give we good just heard a quick check in from them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at 8 and then we'll let it hang out there for a couple of minutes I'll let the thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure drag is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressure starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for 1 hour and 13 minutes um it flew by by so so quickly um on pressure approaching one PSI on P2 I'm I'm sure for shared and Sarah it flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core Arthur barrial that's going to come uh once we are done with the repress repress operation I we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the pure2 environment in the suit using Nitro before they get out Nitro being that same air mixture that you have in your scuba tank uh if got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there they're just going to keep pying out should hopefully be getting video back from ground stations and by for transition to ress 2 at 8 decimal 3 and copy that SpaceX we're following along ref press two at 8.3 and so once we transition to repress 2 once we're at about 8.3 PSI will'll stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we've got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hopefully just about a minute and a half or so away from ground station so might get those views back inside a dragon yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh pause refres to scw up Che e1's good and yeah that com we're hearing half before we get to El monitoring check have a continual checks with all four crew members to make sure that everyone is good um if the answer to one of those checks was no there would be an option in this repress sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depressurize now this repress seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to take up but we're going to pause at 9: we're going to do another cabin leak check so we should hear that momentarily time evess two [Applause] stop Dragon space with you and Eva repress to stop waiting 5 minutes for Thal stabilization C that SpaceX we're tracking and pro for awareness we do a positive refres R we are 30 seconds in6 like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness PP 1 decimal 35 halfway there the suits are still flowing that oxygen um and in a few minutes we will begin to flow we'll do a flush uh of of nitro uh into the suits all right we got our views back there they are it's a little sad to see that forward Happ closed again it's it's got to be really hard when they tell you it's time to go back in yeah just one more minute yep reminds me of when I was a kid swimming in the pool you know time to get out just one more minute I mean it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a [Music] timeline tp2 just passed 1.5 we're a couple minutes into our Le check you're you're seeing the pressure continue to tick up we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that is why you're going to continue to see the pressure tick up you heard Jared call out the P2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14 14.4 so and I mean that's that's a little bit lower than what we're walking around in now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that nitrox uh that K was talking about uh that takes them out of that pure oxygen environment and that's one of the final steps before we'll he hear that call from Arthur Eva operations complete and that's when our clock's going to stop uh our space walk did start today at here at SpaceX in Hawthorne California and I'm Dan huitt from the communications team now the first Eva in history was performed in 1965 by Soviet cosmina Alexi leonov followed just 3 months later by the first American spacewalk done by Ed White during the Gemini 4 Mission from those humble beginnings to walking on the surface of the Moon repairing satellites building space stations in orbit space walks are really a core component of human space flight well Evas are wellestablished procedures for NASA and other space agencies this will be the first Space Walk using commercially developed hardware and procedures and spacex's brand new Eva suits which we debuted earlier this year now we've tested extensively in vacuum Chambers here on Earth but this is the first time that the suits will encounter the vacuum of space and on board the dragon spacecraft right now is the Polaris Dawn crew starting off you got Mission Commander Jared Rook isaacman Mission pilot Scott kid potit and for the first time ever we're excited about this two SpaceX employees Mission specialist Sarah Cooper Gillis and Anna Walker Menan who's serving as the mission specialist and medical officer four members of the crew have been orbiting Earth for 2 days since they lifted off from launch complex 39a at Kennedy Space Center on Tuesday September 10th it adds up to about 15 to 16 orbits around the Earth every single day in County on day two of the mission as you can see there on your screen Dragon fired its forward Draco bulkhead thrusters to send the spacecraft soaring higher than any dragon mission to date reaching the highest Earth orbit ever flown the crew uh topped out at more than 1,400 km breaking the record set by gmany 11 a half century ago when that spacecraft reached 13 excuse me 1,373 kilomet this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 since that time dragon has gradually lowered its apogee or the highest point in its orbit as the crew got ready for the space walk today they started to Dawn or put on their Eva suits just a little bit of time ago and they've been undergoing a process called pre-breathing where the atmospheric pressure inside dragon is slowly decreased and oxygen is increased to prepare their bodies for the Eva suit environment we're going to dive more into the operations of the spacewalk a little bit later and we're going to be hearing in live communications with the crew throughout so be sure to listen in as those happen yeah it's going to be super exciting to hear that and as far as views goes we'll have dragons regular internal cameras that we have seen before and up to three external cameras one aimed at the hatch uh kind of like what you see there uh one on Dragon's nose cone uh which actually is the one that's there that's the the the camera on the nose cone and one on the newest piece of Hardware that you see there in that view we that is the Skywalker um which we will come back to shortly we may also have helmet cameras that will give us a first person view from the crew which will be incredible now since we are not using starling to uh enable views today there will be moments of expected loss of signal due to ground station coverage so those views may be interrupted from time to time but generally we expect to get some great shots today and as of right now we're less than an hour away from the start of the Eva for now though let's learn a little bit more about the mission and our crew the Polaris program is a first ofit kind effort to rapidly Advance human space flight capabilities while continuing to raise funds and awareness for important causes down here on Earth today's goal is to demonstrate critical operational capabilities that are going to serve as those building blocks to help further human space exploration Polaris Dawn Mission has a lot of firsttime objectives so the Polaris program chose a crew of experts who know each other so they can tackle this mission's challenges as a team first up Mission Commander Jared Rook isaacman also served as the commander of inspiration 4 the world's first all civilian mission to space Jared holds several world records including two speed around the world flights in 2008 and 2009 for the Make A Wish Foundation he has flown in over 100 air shows as part of the Black Diamond jet team dedicating every performance to charitable causes in 2011 Jared co-founded what would become the world's largest private Air Force dren International and that trains Pilots for the US armed forces in addition to his role as CEO of shift for Jared is an accomplished pilot and astronaut with over 7,000 flight hours next up Mission pilot Scott kid potit who served as the mission director of inspiration 4 and he goes by the nickname kid which is also his call sign he's a retired US Air Force Lieutenant Colonel kids served for 20 years in roles that included commander of the 64th aggressor Squadron Thunderbird number four demonstration pilot US Air Force weapon school graduate operational test and evaluation pilot and flight examiner he's a command pilot with over 3,200 flying hours logged over 400 hours of combat time and following his Air Force career kid served in various roles including vice president of strategy at Shift 4 Mission specialist Sarah Cooper Gillis is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew 1 missions and most recently directly trained the inspiration for or astronauts Sarah is an experienced mission control operator who has supported real-time operations for Dragons cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for dragon's human space flight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program fulltime and capping off the Polaris Dawn crew mission specialist and medical officer Anna Walker Menan who serves as a lead space operations engineer here at SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragons crew capabilities and developed critical operational responses to vehicle emergencies prior to SpaceX Anna worked for seven years at Nasa is a biomedical flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going to space that's clear but let's take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isaacman I'm Scott kid potit I'm Sarah Gillis and I Anna Menan and we're the player Don crew I Love This Crew I mean all of them are just so hardworking so smart kid potin over here is our mission pilot talk about a career in the Air Force doing every job as a pilot that that anyone would aspire to achieve and having somebody who has you know been there before and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always there glue glue you are always there predicting what every person means um and he's needy what our commander Jared I think he is incredibly sharp that's right something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical confidence we don't get out of any engineering update or brief or go through a procedure or debrief without getting into the weeds and making sure every tea is crossed every guy is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared that served her in her role as core it serves her in her role as a trainer Anna you have this incredible joy that you bring to everyday life it is infectious it makes us all smile feels like she always has this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then as a biomedical engineer and a background like that inspires like a ton of confidence that you go up there if uh if people aren't feeling right that she's going to be there to take care of I cherish all the moments that we've had uh in these experiences and uh we're just so excited to to go to space now that you know a little more about the Polaris daon crew let's recap the mission so far and what's coming up next since lift off and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours demonstrating the Eva suit's pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I mentioned earlier on day two dragon proceeded to a high apogee of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the space walk dragon has been executing a series of a apogee Ling apogee lowering phasing Burns by now dragon has lowered itself from the highest apogee of the mission of more than 1400 km to about 190 by 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude children research hospital um and they they're joined Live While polaron crew member Anna Menan read from her new book kisses from space along with the patients and families at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the Polaris Dawn crew Enlisted the help of Childhood cancer survivor live to create the missions Zerg indicator while not a St Jude patient herself Liv met the inspiration for crew and inspired by the mission of St Jude she agreed to share her talents to support polara stone is live and I spell it l and then an apostrophe mark exclamation mark I can tell you anything about space from the miles from Earth to the Sun to every Mission basically I had cancer in 2021 cancer Survivor like Haley I really have a passion for wanting to help St Jude and other kids who have those struggles as I had so I first met Liv a couple days after I got back from space at our Splashdown party and I got to meet her family and they told me about her journey that she was on I remember that she gave me a card she had written and it said thank you for helping other kids with cancer like me I hope to go to space like you someday and my eyes just filled with years whenever I read that basically my one passion is to um be the first child in space Liv was really close with the players Don crew and they asked her to design the Zerg indicator a zg indicator is like a little plush toy that floats in the air it basically shows that you're in Zer they kind of hide it over in the corner and then once you hit theg it'll float up and reveal itself my main idea for asteroid is B on ean's dog POI I I've always loved Sheba they've always been really cute and then when I heard Ean got POI I was like done I love her I want asteroid to be for every child and help them see oh asteroid went to space and I can too I can achieve my [Music] dreams we are also flying Liv's original drawing that you see there that was used to design the zg indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital all donations from the sale of asteroid will will be General donations to St Jude the inspiration 4 Mission helped raise more than $240 million for St Jude Children's Research Hospital and poan will continue to raise funds and awareness for St Jude while partnering with the organization to provide healthare in underserved communities around the world now if you want your very own asteroid they are available at shop. spacex.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the way so be sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got like I snagged one I got in there I got a kid who nice needs one yeah all right now the first phase of the spacewalk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre-breathe process started that's when the oxygen levels started to increase incrementally as the actual the cabin pressure inside Dragon was started to get incrementally lower the pre-breathe process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any space walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure de of in deep water back up to the surface and to do all this dragon's just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in the suit during the spacewalk itself they've got the ability to pause the process if they experience any discomfort but the ear ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude on an airplane um all four astronauts are going to be suited for the spacewalk today because Dragon does not have an airlock that's also kind of why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with this stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah are just going to be lightly secured ahead of the spacewalk since they're going to be moving around and eventually heading outside as we listen into comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support two is Anna again they will not exit the dragon during the Eva but make no mistake they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rotate those upright during the Eva just to give more room to move about after that seat rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tabs in the health of their suits and they'll get some other stats of their suit operation during The Space Walk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations brief from the SpaceX team the crew will announce their go noo status and then it'll be time for The Space Walk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the cruise suits until we complete the repressurization of the cabin and just prior to we get to cabin venting pure oxygen is going to start flowing to the creu suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the sun this will help keep temperatures Communications and spacecraft power stable during The Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during The Space Walk he's going to be the first to exit the spacecraft he's going to go outside is going to do a series of Mobility tests these are kind of the core component of the spacewalk today he's going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into Dragon after that ev2 or Sarah will step out into space to perform the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit then after she's completed her test Sarah will stand by near the hatch for the actual closing and then at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is Suited up and awaiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the Space Walk and before we get there though we're going to expand the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back here in Hawthorne with you tonight on this uh very memorable night for sure yeah absolutely uh now Evas may be new to SpaceX but uh you have participated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two Mission you know the first one was back in 2013 and I uh I went up on a Russian soy use and on that one we had two space walks and the interesting about those space walks is they weren't planned they were what call yeah they were a big surprise for us uh contingency Space Walk and of course surprises happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a space walk as everybody was getting ready to celebrate Christmas just helping deliver pres that's right that's right and then your first play was on the so but your second one you were the commander of crew one I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than anybody because you you actually got to call at home while you were docked up there that's right it I mean I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was in a great amazing group of people not only uh uh Victor Shannon and suichi but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough crew stations and actually you can see a picture of uh of where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the station where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for crew Wen they they were yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees and somebody else getting to uh getting to test them all the time so uh yeah it was pretty neat to to get to see that switching it up a little bit because we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to 1400 km uh we like to talk about something called the overview of so kind of that first that and we're getting some coms from our crew too yeah nice space Dragon radio check C clear kid me got you loud and clear dolphing continues unless though just going to be right captain cover that kid make that D all right some some quick com checks we heard kid that Scott po he's going to be one of the support crew in there today so our our first calms down uh as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back back and I mean you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overie effect is definitely real but when I first got to space um on that on that soy use uh go how many years ago almost nine years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now now this feel really that's pretty but oh no um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you'll hear people talking about that that small sliver of atmosphere and you you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me a lot of questions and made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it brought as many questions as it did answers hopefully a bunch of bunch more trips then right that's right that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank white originally coined the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habitable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different emotions that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moon rise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to Mars and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of four is next support two is next and then ev1 and two are surely behind cpy on that crew status getting a quick quick crew status from kid uh yeah I I think I speak for a lot of space exors we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dra and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean spacewalks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first Space Walk is a contingency we had a failure and so sometimes when we're going outside it's it's not planned and you you have a component that that uh is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out and we're putting a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar rays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Don crew is going to do today and you're just checking out the suits and checking out the equipment that that you're going to use in future space walks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction requiredby actually uh if I can I'm just going to jump in on that that's actually a very important call that was made you heard them say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around at what was that and so you heard them give them a warning that we're going to turn on some fans yeah and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those spacewalks where I was uh at you know outside and and what are you proud of you're you know it's it takes so much to put these vehicles up into space and and so when you go out on the spacewalks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because people are depending on you and couple people watching over your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good station's back up 100% just like okay that's that feels great Dragon Space X our fan commanding is now complete tell we all right hopefully no surprise sounds in there for him so I mean spacewalks are something that you you train the heck out of they're they're playing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a space walk yeah so I mean one of the first challenges that you're always worried about is the how your suits functioning right because that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground are monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between you and the in the ground and so they're making all of those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about spacewalks that uh maybe people don't realize is you know you focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they ex the these space walks um they they you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk it no never felt like a Calk at at all um you know it because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely um very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on you're more familiar maybe as a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I will equate a little bit of of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all of that kind of nervous energy as you're getting ready to go out well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on seat rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them up right that's just going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is spacex's 14th human space flight Mission since 2020 when Dragon became the first private spacecraft to take humans to the International Space Station it's also the first private spacecraft to take an all civilian crew to orbit during the inspiration 4 Mission in 2021 and just prior to Polaris Dawn Dragon completed four 46 launches 13 of those are human space flight missions and it's since flown 50 astronauts representing 14 different countries throughout all of those missions dragon has helped support more than 1,000 experiments in space pretty incredible stats there um and even from low earth orbit dragon is helping lay the groundwork for deep space exploration through missions like inspiration 4 and Polaris Dawn we are rapidly expanding our knowledge of how humans will adapt live and work in space designed to be the safest spacecraft ever flown the fully autonomous Dragon stands nearly 27 ft tall and 13 ft around dragon is capable of carrying up to seven passengers to and front Earth orbit and Beyond but today it's carrying the four members of the Polaris Dawn crew and the crew is currently living and working in the top portion of the spacecraft that's that white section that you see there also known as the pressurized section the allows for the transport of people and environmentally sensitive cargo below that dragon's trunk it sits right below the pressurized section that can carry unpressurized cargo on resupply missions and it remains attached to Dragon until shortly before re-entry into Earth's atmosphere and as you can see about half the trunk is covered in solar panels those provide Power to Dragon during the flight the other half is the radiator Dragon itself is equipped with 16 Draco thrusters we got real really cool view of the four forward bulkhead ones firing earlier on this flight with lights on Earth behind you those are used to orient the spacecraft during the mission they also get used for apog and Pary raise and lower Maneuvers orbit adjustments and attitude control the Eva the Draco are going to be used to reposition Dragon so the trunk is facing the Sun and they're also there to be used for reorientation during the space walk if needed in order to accommodate accommodate a spacewalk this is the first draft Dragon to be outfitted with a Skywalker in place of the Koopa observation Dome the Skywalker that you see there looking up at it uh from the from basically from underneath it um the Skywalker is a structure that is mounted to the top of the Dragon capsule and the astronauts will use this to assist in exiting and re-entering the spacecraft during their space block the team also added additional nitrogen tanks to assist in repressurization of the capsule after the Eva another new feature on Dragon is the addition of a motor plus hand holds and footh holds inside the spacecraft to help with opening and closing the hatch during The Space Walk This Dragon also carrying what we are calling the starlink plug and pler making this the first mission on Dragon to use the starlink network in orbit inside a dragon is a router connected to a user terminal in Dragon's trunk and then this terminal is linked to a new plug-and player device that's mounted nearby while we're not using starlink for continuous coverage during this operation we've been testing its ability to establish and maintain laser Communications with our starlink satellites there in orbit that are below dragon dragon has proved to be quite a versatile spacecraft it can autonomously dock to the space station when outfitted with the ISS docking adapter and when it's intended for free flyer mode the docking adap adapter can be swapped out drag and you guys are welome to come on back aboard if you want SpaceX copies don't have uh ground station right now but we'll go ahead and bring cameras back on board so we get it when we do have ground stations quick comms there with SpaceX core uh from the Dragon capsule that was uh the crew just letting the folks here uh in Mission Control letting us know that it's okay to turn the onboard cameras back on once we have uh coverage for those cameras um but getting back to the different um configurations that we have for the Dragon capsule um I was talking about the docking adapter previously when the dragon capsil is intended for free flyer mode docking adapter can be swapped out for a Cupa uh which is the one in the middle there and that is used for the best views that you can get while in orbit and then of course our newest option the Skywalker Hardware to support extra vehicular activities and that's what the crew is going to be using this morning so those are the current three ways that dragon can be configured to support different types of missions but hey you never know what's to come we always got something up Our Sleeve right now Mike crew one broke the record for the longest space flight by a us crew vehicle surpassed the 84-day mark that was set by an Apollo capsule during that final flight to the Skylab space station in 1974 what was it like cuz we went over it you literally called Dragon home during that time what was it like to live in there so so first of all I got to say it's pretty exciting because uh the the dragon that they're using right now is the dragon that I lived in that took us to orbit uh yeah we affectionately called resilience uh and and it was a it was an amazing spacecraft uh it it uh from a standpoint of living inside it and um again it it a lot of room actually compared to some of the other crew quarters that we had on board and uh and and plus just uh you know being able to to uh spend all that time in it you know i' call my family every night before i' go to bed and I'd be looking out the window uh at the Earth uh as as I was doing that it was uh very special did did any of them get jealous CU you had the window seat well yeah there was a little bit of that certainly uh going on up there nice now as you mentioned this Dragon capsule that the inspiration excuse me that the Polaris Dawn crew is flying in was previously used uh really debuted on the crew One mission hence why you guys had the um honor of naming it in the first place but this capsule was also used for the inspiration for mission that uh Jared also commanded um what is your take on uh this being one spacecraft but supporting multiple missions I think it's fantastic it just shows the flexibility of the design that SpaceX made when uh when looking at the crew Dragon Vehicles so I I I think it's very exciting to see a vehicle that can that can go from one mission to the other and and quite frankly do it quite uh quickly as well I think I think I don't remember the exact timing uh from our mission and when we landed to win inspiration 4 launch but it wasn't a very long time and yet you were able to take that docking adapter off put the uh KOA on in a in a very short time which is also pretty impressive I actually have that noted here uh crew one took off in November of 2020 and inspiration 4 lifted off in September of 2021 that's that's a yeah we landed in May of 21 and So within that short period of time you reconfigured the vehicle and uh and we're able to put that c on and launch yeah very impressive your mission patch sticker is in the is in the capsule that they're in now and add their own sticker to as well right all right well as you can imagine dragon has undergone some changes for this and with changes comes extensive testing for the mission and all the modifications that we made in preparation for today had to go through kind of their own test regimen yeah testing is a critical part of qualifying a space like Dragon for flight rigorous testing helps identify and mitigate potential risks verify system and component reliability and helps ensure that the designs meet the mission requirements there are many types of tests a spacecraft might undergo when qualifying for flight including structural thermal vacuum radiation software and Integrated Systems testing one of the tests the new Skywalker Hardware underwent is thermal vacuum testing this actually tested how Skywalker withstands the extreme extreme temperature swings that it's going to see while it's in the vacuum of space and while Dragon was being put through all of its Paces the Polaris Dawn crew was going through the same SpaceX training uh as part of our that we give to NASA astronauts they also had to train to perform their Eva though for basic training at SpaceX Hawthorne they train on everything from orbital mechanics to just how to live and work in microgravity also ran through numerous simulations of what the full mission would look like while they were seated inside of our Dragon trainer in addition to ensuring that they're familiar with spacex's Falcon 9 rocket and dragon spacecraft the crew went through an extensive training regimen to build their physical endurance and mental toughness ensuring that they are well-rounded and prepared for space flight and today's Eva now switching gear is one of the coolest things designed in-house by SpaceX the Eva suit is all the functions of our original space suit with the added bonus of allowing astronauts to exit the spacecraft while in orbit and this Mission this Mission gives us a great opportunity to test our Eva suits in space building a base on the moon and a city on Mars will require thousands of space suits so the development of this suit and the Eva performed on this Mission will be important steps toward a scalable design for space suits on future long duration missions as we mentioned SpaceX designs and manufactures our own suits we have a little behind the the scenes look for you something most people don't get to see the inside of our very own suit e e e introduce this new single pane visor helmet to the world of space suits the Eva suit visor is made of polycarbonate and is coated with copper and Ito or indium T oxide these two Coatings together reflect the Sun away from the crew as well as reflecting infrared heat back to the crew when they are facing deep space our suit has a HUD or heads up display which is a small display screen in the helmet which is transparent which allows the crew to see through the display to have unfettered access during their Eva but it also provides critical Telemetry to the crew so pressure temperature relative humidity we're trying to improve the technology and streamline it in one way and at the same time we're also trying to get it more and more manufacturable with each generation the ultimate goal is that you can put on a space suit and go out and get work done anywhere in the solar system um and not feel like you're wearing anything more than you normally wear every day [Applause] [Music] we also had a chance to talk to the SpaceX team that developed some of the hardware and procedures for our first Space Walk let's hear what they had to say Eva stands for extra vehicular activity and it's any sort of operation in space where a human is getting out of the spacecraft so in the case of Polaris daon we're going to be testing the mobility of the suit we're going to see if the inp space operation matches the training we've done here in Hawthorne there's really a lot of different things that can happen during an Eva and this is the first step for Dragon and SpaceX when I first started working at SpaceX I never thought I'd be training a crew to do an Eva it's brand new it's so unique we've never done anything like this before and so we wanted to make sure we had the best possible training program for this Mission we want to see if we can train a space walk on earth in a way that's represented of what it feels like in space even though only two people are going to be going outside during this first Eva all four crew will be in Eva suits going down to vacuum Dragon was always designed to vent to full vacuum but we've never taken full Dragon capsule down to vacuum and this will be the first time we do it in space we actually put crew into a chamber at Johnson Space Center in Houston and had them live the exact profile that they will experience and making sure that no one actually experienced uh decompression sickness we have a couple new training assets for player ston to train the EPA specifically the suspension system that we have is situated on top of the platform of our capsule Simulator the lines drop through the hatch they attach to a single crew member inside the capsule we can lift them up and get them situated so that they can ESS the capsule and perform their tasks at Skywalker the mobility Aid the Skywalker what's amazing to me is a lot of people are going to think it's a metallic structure just bolted to the top of dragon but a lot of development effort testing went into the Skywalker so we actually used similar technology as we have in the super Draco Chambers to apply a thermal barrier coating to the outside of the Skywalker that is going to be a really really amazing Mobility a on the front end of dragon we also developed a sideways simulator so we flip the hatch on its side in the event the hatch fails to close they can manually close the hatch we had them do that in a sideway suspension system so gry isn't helping them close or helping them open that hatch mechanism it's new development for Dragon it's new development for SpaceX and the industry as a whole so this is a great example of where polaron is forcing the team to innovate in a way that adds safety and reliability to every dragon mission going forward that's this huge challenge for us to go solve but that's also an opportunity for us to solve the problems that we have to go figure out anyway for our larger goals like putting people on Mars the Piston objectives are the first step towards that ultimate flight with with humans inside of Starship which is right along the SpaceX development path that that we have towards getting to the moon and Mars love seeing how not only the suit but the space operations for the Eva itself uh came together and were developed uh now we are still counting down to the spacewalk this morning uh the crew is or EXC me the crew on board is completing final fit-ups and we're going to be standing by for seat rotation and suit leak checks so we're continuing to truck along to the the the main event uh now Mike you obviously went through some of the suitup process that we saw in that package in terms of um the the development of the suit and how it's custom fitted for each individual and that's that's the same case for an EV suit so maybe you can share with us what that experience was like yeah it it's extremely important uh to to have a suit that fits whether again it's the Iva the EV Eva suit or the Emu that we wear with NASA when we go out on the spacewalks and the reason for that is because if it doesn't fit right it can be extremely uncomfortable you can get what you call hot spots or uh there can be a a a place where the a crease when it gets pressurized can really put a a uh a hard point on your arm or something that that nature so having a good suit fit check is extremely important and and it's one of the things that was kind of fun as well because you get to spend a lot of time with the the suit team here with Chris and Eric and Mar they're fantastic and and I mean just over the years they've gained so much experience and they can really help you hone in on what a the really good fitting suit is is like with just the way they ask the questions and lead you through that that process wow what are what are kind of The Sensational differences from being in like the Iva suit because a lot of times the Iva suit when it gets pressurized you know it fills up but you're still in like a pressured environment with Eva suit you're in the vacuum right and so like what's what's it kind of like yeah so you know that Iva suit it has a different purpose right and that the purpose of that Iva suit is to Keep Us Alive in the event of some type of an emergency that might happen during a launch or a landing and and so that's that case where either you have a fire or you have a depress event and so that suit's going to pressurize and so in that case we're not as worried about like the mobility of of the suits you just want to get home and and do it in a safe way and so you need to have enough Mobility to still be able to control the spacecraft and and do the things you need to do but but you're just not as worried about it because you're not trying to perform a maintenance activity or or something like that when you're going down on the on a on a spacewalk and and so I think that's that's one of the the biggest differences between the Iva suit and the Eva suit is just what the purpose of it is and what you're trying to do with it yeah that feedback loop um is so important to be able to communicate what feels good what doesn't um because I imagine um you know as you're out there and having to perform you know as you mentioned maintenance activities uh among other things that the functionality of your body is critical to to to perform those it it really is and probably one of the hardest I think parts of the suit to design is the gloves right because absolutely you know you hear us use the term it fits like a glove right we use that a lot but but you don't realize how much you use your hands when you're outside on a space walk as opposed to say your feet when you're you know because in space we don't use our feet our legs as much as we do our hands and and so when you're in a a pressurized suit like that and you're constantly grabbing and reaching you are overcoming the pressure of the suit and your hands can get just exhausted and you can get those hotpots um I had some issues with my emu gloves when I first started training at Nasa and I would actually get uh what's called delamination on my fingernails yeah and and so there's just little things like that that it really matters how well that suit fits and and how well it functions and and so uh it you don't realize how important that is sometimes yeah um now we are going to be stepping into suit leak checks soon um can you you share with us a little bit about what that process uh entails um and and and more importantly because you you've actually experienced what it feels like to go through suit leag checks what what that experience is like extremely important part of the whole process right because before you take the cabin in this case all the way down to vacuum you want to make sure that your suit is maintaining the pressure that it needs to and and so it's a it it's a not a very long process it's usually just you know a few minutes to two or three minutes um and you know the the interesting part is if you don't pass that lead check what do you do next and and so there's always usually procedures associated with that as well that start checking your zipper start checking how you've closed things up did you not get something sealed quite right um and and so it's always a good point in the mission when uh whether it's on the Launchpad getting ready whether it's in the airlock getting ready to go out the door when you when you hear that yeah good Le check uh because now you know that you're ready to go so today's going to be kind of unique because all four of our crew members are going to be like doing The Space Walk they're all going to be exposed to the vacuum of space but I mean even when you did space walks it's it's never a solo act right like you're always out there with a partner you you are it's uh it's extremely important in fact one of the hardest parts about our training for space walks is what we call incapacitated crew and so you need to always be able to get your crewmate back into the airlock if something should happen if uh if they should no longer be conscious and and something of that nature and so we we actually do spend quite a bit a time and that's why it's extremely important for us to go out in pairs because things can go wrong um and and so you want to be prepared for those those moments yeah uh that's a great Point Dan to make that um while only Jared and Sarah are going to be somewhat exiting the spacecraft um all four crew members are going to be exposed the vacuum of space and it's actually going to set a new record for most number of people exposed to uh or not them without a suit but like yeah in the vacuum of gravity all at the same time yeah that's actually interesting I never I never actually thought of that piece of this Mission and the fact that you're going to have four people on a spacewalk I I know at one point on a shuttle mission we had three y three folks outside on a on a spacewalk um and so yeah that's a that's a big deal and and kind of exciting you know one of the one of the things we do on the on the space station of course is We Have astronauts that are still inside and if we do get into those emergency situations they're there prepared to help us uh get back into the airlock and and uh and get unsuited and and things of that nature so of course when you have all the crew it just makes you think about those emergency situations probably in a little bit different way than we than we do on station yeah and hey if you're just tuning in we are still waiting to really kick off our space walk today so right now the crew is in inside the spacecraft they're getting suited up we should be hearing some coms from them pretty soon and then X Dragon um ev1 is completing glove zipper closur but at this time we are ready for seat rotation copy that for SE rotation can you confirm crew is ready with the current glove zip props all right I I guess they just needed me to to say it was coming soon and then and then there it is uh but uh we are going to hear the seat rotation coming up soon again they're in the reim position stand by get the seat copy standing by so they're going to get those seats rotated and then we're then we're pretty much going to be ready to start getting into things and uh our Eva is going to officially start when we start flowing O2 into those suits um and so that'll kind of start our clock we're going to be showing you some of the Telemetry so all those numbers the bottom of your screen you've got a couple right now uh that one all the way in the bottom left corner that's your dragon that's your dragon cabin pressure that's in PSI ready for SE location space SI copies initiating seat rotation great news there that's going to help give the crew a little bit more room to move around uh during The Space Walk and after we get through the seat rotation we'll be able to perform those suit leak checks that we were just talking about yeah before they do that they'll do what's called a tear so it's kind of like if you're ever using a scale you zero out the scale before you put something on it it's essentially what we're doing with the suits they'll get like a baseline reading and then as we start to actually pressure the suits we'll be able to measure that against the Baseline make sure everybody's got basically a nice seal before we start that vent yeah that one's pretty important that was pretty important yeah um so a lot of that's coming up again some of the data on your screen you've got cabin pressure you've got suit pressure Dragon SpaceX seat rotation complete and nominal all right seat rotations complete so now they're going to start doing that tear getting ready Cy and can I get a confirmation of completion per the call out in 2 decimal 18 complete with 2 copy at this time you are go to step into section three and teror suit [Music] deers now just a quick reminder in case if you missed the top of um the show we're we're going to be referring to the crew a little differently for the Eva activity um than we were previously so we heard Anna uh talk ev1 that was referring to Jared so his basically his call sign for this uh spacewalk operation is ev1 um Sarah's call sign will be ev2 Anna will be support two and uh Scott will be support one uh also Scott and Sarah are switching seats uh I perhaps they already have copy stand by for HUD power for pressure sensor checkouts okay so our suit tear completed so next up is going to be the HUD checkout so the HUD your heads up like real quick we do have on your screen though that's your seed order so uh you've got ev1 Jared uh is in that seat he's going to be in that seat right now but once we actually get ready to open the hatch and everything he's going to be positioned kind of over by the hatch and then Sarah ev2 is going to be in one of those Center seats then you'll have Anna and kid on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks in three decimal 2 so again that's our that's our SE layout we just heard the Huds are powered on so they've got heads up displays actually being kind of projected on their visor in their helmet which if you if you've ever seen space suits that's always kind of felt like that's that Space Age Technology that we're missing cuz Mike you guys use kind of a a simpler but a little unorthodox way to see like your suit data yeah that that's right Dan it's uh of course this the suits and they checkup complete copy swapping the backup sensors standby to repeat H checks so of course the suits that we use for the the space walks on station are a little bit older they've been around for for quite a while and and so some of this uh technology uh you know look it's our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chilling yeah so there out of his seat that's Commander Jared uh who like I mentioned before will be referred to as ev1 behind him we can see already in his new seat uh pilot Scott kid potit uh he will be support one and then moving around in front of us is Sarah who will be ev2 and then just out of view underneath the camera but I think you can see her visor is um an a Menan who is support to Dragon SpaceX we're on backup sensors repeat Hut checks the crew is going to check out those heads up displays one more time real quick check back copy good Huds returning to primary standby for helmet camera checkouts on that heads up display they'll be able to see the the O2 flow timer that's kind of like our mission clock essentially like once the O2 has started to flow to their seats and they know they've got a about an hour and 50 minutes just under two hours for the whole time uh they'll be able to see their suit pressure temperature basically it's a way to kind of keep an eye on things and we were talking about it a little bit Mike but on the Emu is a little bit different yeah the Emu is certainly different uh a lot of that kind of information is on a on a display right in front of you that you have to kind of look down to see and it it can be pretty challenging to see in fact a lot of the information you have to use a mirror on your wrist uh to be able to to read it and know what you're what you're controlling as well uh you mentioned the timer of course we don't have that kind of information on on ours and I'm not sure I'd want to know that because I'd feel the pressure of I got to get a lot of things done I'm running out of time yeah all right um so they're they're going through these HUD checkouts again pretty soon Dragon Space X powering on helmet cams we're going to get the helmet cams powered on again give you that kind of look right over their shoulders yeah pretty excited for these we've uh seen them utiliz during the training uh sessions that the crew has undergone and we're so excited to to see them live today yeah I I tell you the helmet cameras I mean it's going to be fantastic views right that we're all going to love but but there's also a very important um role for those cameras as well like when we have the same thing we have helmet cameras with the emus and what it allows is your ground team Dragon SpaceX suit cameras powered confirm good health so it really allows your ground teams to to kind of be able to see what you're doing and see a good video and almost double check your work copy check out's complete Huds will remain powered proceed to step 3 decimal c 3 operations review through 3 decimal 8 report one complete all right so we got through HUD checks we got cameras on powered ready to go so right now the crew is going to go through they're going to do kind of a final review of all of their procedures like you talked about this a little bit like these things are so choreographed because even if you couldn't see the clock like you're on the clock so you've go to you've really got to make the most out of like every single second you're doing one of these you do and and of course you see that with with today's space walk as well space X repeating checkouts are complete Huds are going to remain powered proceed to step 3 decimal 3 operations review through 3 decimal 8 and Report when complete Happ the and and the reason it's so choreographed and important is because you only have so much time outside right you only have so many consumables that allow you to go out there and so you want to take advantage of all of that and you want to have every step very well scripted so that so that there's not a lot of wasted time now that being said it is nice when you're out there once in a while to just kind of take a moment look around enjoy the views kind of try to absorb where you actually are which uh can be pretty incredible as well every every once in a while guys I'm a little tired I'm gonna take a minute that's right I need to take see my house from here that's right yeah all right but like it's it's awesome we're seeing the crew inside we're getting close to the start of today's Space Walk we're going to start flowing O2 to the suits and that's when our clock's going to start right now they're just doing kind of final cabin configurations they're going to check the lighting uh they're going to make sure that their umbilicals are in the right spot that's one of the things you'll see that's actually one of the the the roles that our support uh crew members are really going to that's kind of one of their one of their primary jobs during the spacewalk is to manage those umbilicals for you guys Mike you had one that's uh what plugs into kind of the leg in your suit and that's what's providing like the breathing gas coms connections all of that stuff uh for the space walk today it's a little bit different this one uh that uh they're going to be using has some tethers in it um for Anna or for Sarah and um Jared it's about 12 feet long so it's like about double double the length of what you guys are so so it's Dual Purpose right it's it's providing them the the air and the cooling that they need while they're out on the spacewalk uh but it's also providing that safety piece right so that if uh if something should happen they should slip or um that that they're not going to go floating off into space with the Emu uh that we use on the space station we actually you know all of those consumables are a part of the suit itself and we have a separate safety tether that the first thing we do when we open that hatch and we go out as as we hook up that safety tether and it's an 85 foot reel that uh as you're moving around it it goes out with you to again protect for that crazy moment when maybe uh an emergency happens and you come off station how how hard was it to manage all of those tethers I feel like every time I watched it was like there's no way in heck that this thing isn't getting snagged on something no you're absolutely right because everything and and you talked earlier about making sure there was no loose items in the cockpit right CU when you open that that hatch uh things are going to want to float away if they're not tied down or stored or anything like that so when we go out on a space walk not only do we keep us Tethered to the spacecraft but any tool any part that we take out with us also has to be tethered and it can be quite a challenge to manage all you'll open up a b bag and there's there's 10 pieces of Hardware in there with 10 different tethers and they get all tangled up and and it can really be pretty challenging it's important though um we simplified that a little bit for this Mission um we actually basically built in that tether into the umbilical one of which you can see actually they floating uh under Jared's right arm so not only does that Pro provide airf flow and comms and uh all the normal connections that we have in the in the umbilicals but we also added that that strength uh to provide that protection yeah and and the managing of that tether is extremely important because you know as they go out if it can get tangled up and you actually see Sarah there kind of moving around right it's it's very easy in in this environment where you're floating PHX Dragon Eva offer you complete who are in position to Eva nice cop CED position but you saw Sarah kind of move the tether out of the way and the part of that is that's actually impacting go to command push a talk all seats and so this will this will be one of the unique things about the space walk today it'll it'll feel familiar if you've ever if you watched some of Mike space walks uh the crew is going to go over to what's called vet set go for check ev1 check ev2 check support one check report two com check SpaceX copies all good coms all four [Music] crew so essentially now all of our crew are on open mics they can all talk and hear each other and they can talk to the ground and so you're going to hear a lot more chatter start to pick up uh once we start the suit pressurization you're going to hear almost like a sound that's just the air starting to flow into their suits um how how loud does it get inside your suit it it actually is quite loud uh that air flow is just constantly which is a good thing right because not only is it providing you the oxygen but it's also helping get rid of that CO2 that you're breathing out so you want that air flow uh to be constantly going and and so you always are here in that van uh that that's uh making that happen and so that is that is certainly pretty important and the Box thing I got to say you know it's nice that you don't have to push a button when you're outside there to to talk Dragon SpaceX or about 90 seconds from E initiation got some fist bumps going on yeah and we just heard we're about 90 seconds from Eva initiation so we should see them get the go to close their visors and then they're going to open up one of the O2 valves on their suits to start the suit Purge and that's going to be the official start of our space walk today so we're we'll get through the the final goes and then we'll see those visors get close oxygen start flowing and we'll be off I love how everyone looks so calm and collected right now I think that's a a a great visualization of just all the extensive training that they've gone through to get to this point this has been years in the making um I'm sure they're excited uh but everyone's focused it it is an interesting time right now right because one of the hardest parts I always found about Dragon SpaceX SpaceX is go for Space Walk operations report visor down ready for secondary O2 flow initiation and crew is go for Space [Music] Walk verify your vience are [Laughter] closed secondary L2 B is [Music] open and that you are go for the EVS ev1 is go ev2 is go support one is go support two is go Dragon Space X initiating secondary [Music] o02 and with that news our Eva has begun so you're you're going to hear it referred to as primary and secondary O2 primary is going to be that primary flow of oxygen to pressurize secondary is largely putting oxygen into their suits to help with cooling but secondary is the first one we turn on and so our O2 flow timer has started the Eva's start at 3:12 a.m. Pacific I'll do the math on UTC in a little bit so this first this first operation or this first step in the operation is a suit Purge so inside their suit obviously when the visor is still open it's still a nitrox environment it's the same as the cabin uh and since they're going to be at a lower pressure than what you can basically live at with with oxygen levels um they're going to be on pure O2 they're going to be a 100% oxygen environment and I mean you guys were kind of in the same thing and it's it's because like your suit can't you can't move a suit around at 14.7 PSI can you no maybe you can they like no that would be pretty that'd be pretty tough to do and and as we talked about earlier that's why that Mobility is so important because uh when that suit is pressurized like that it it can be challenging to move around absolutely so here on your screen we can see the polaron crew now with their visors down the Eva has begun we are beginning to flow that uh O2 through now we will of course bring these views to you as we have them but due to ground station coverage they do come in and out here and there um but every moment that we can we will certainly be sharing these with you um I also wanted to point out quickly that the the the window near kids feet was so much brighter than it was uh just even five minutes ago we're going to be seeing that uh in STK contrast as soon as we get uh the Eva or with the hatch open and ev1 out there yeah it's kind of interesting you you you mentioned that because is as you're going around the earth as fast as you are right in in 30 minutes or 45 minutes or so you can be passing in and out of that sun and and going into Shadow and and so that brings its challenges as as well because the temperature um can change pretty drastically just in those transitions from night to to Daylight and and so there's a there's a it's an interesting moment when you're passing through uh through that time that's actually one of uh the reasons that the visors have this new new coating on them different than when you wore the a similar helmet um that coating actually helps to insulate the individual inside the suit so when they're looking at the sun dragon Space X a reminder after the initiation of primary O2 flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow initiation [Music] one copies D2 copies Dragon Space X secondary flow Purge complete close secondary O2 valves and Report ready for suit pressurization ev1 closed ev2 closed report one closed report two closed b x dragon is ready for seat pressurization initiating primary o02 [Laughter] this is normal this is with the air flow coming through uh the crew members on Vox meaning uh that their their microphone is on the whole time so Sarah and Jared are going to be adjusting their audio levels um as this flow continues to to help regulate that yeah the the the Vox will kind of attenuate so it'll it'll sound like this now but as we get through The Space Walk it'll kind of come down and you'll just Just Hear Voices a little bit more clearly uh their their voices are actually going to change too like did that did that happen to you did that throw you Mike the first time you heard that it absolutely did yeah cuz you're you're you're talking and you're going who is that right you don't realize how how much different it can sound um your voice can sound in that lower pressure environment yeah speaking of lower pressure we can uh we can see the pressure changing there with the Telemetry in the bottom left hand side of the screen so we can see that suit pressure going up um and we're able to keep tabs there um as well with the dragon pressure so Dragon uh on the far left Circle that's the pressure within the cabin and then suit obviously that's the pressure within the suits so we'll be actually be able to and I think we've kind of been able to see it already um that these suits will inflate a little bit um look a little different and we were talking about the the visors before so when they're in the sunlight that coat will help keep them cool and not overheat them and then when they're in Shadow it'll help keep them warm so uh and it's also like your sunglasses as well yeah right serves that purpose all right so at this moment the suits are getting their primary pressurization this takes about 3 and a half minutes a little bit less and then we're going to go through those actual suit leak checks I the crew will probably get a reminder they have to stay really still when we do those leak checks and I always was kind of wondering like why the heck and like if you if you bend your arms you're actually going to start you know changing the volume inside the suit that'll cause pressure spikes and so that's right got to stay really still yep and then after after we get through the Le checks we're going to go through kind of that final pre-breathe uh where they're going to hang out in that 100% O2 environment just to continue purging all of that excess nitrogen even one open one one open the sh open and right there they they finished the purge and they did a quick uh reinitiation of that secondary flow check secondary flow and rep Portland complete give one close L [Music] you part one second [Music] second these handles that we see Jared holding on to these were one of the additions uh or uh customizations for this mission that we talked about [Music] [Music] earlier support one St TX Conta [Music] [Music] we got you all right copy [Music] got Dragon Space X beginning Sly check evaluation and then still for the [Music] okay so once again that background noise is expected um that is the microphones and the flow of air uh within the suits so we're trying to stay quiet to uh along with you listen in on what the crew coms uh are as they go through um we're also uh going to get views in and out as we mentioned before due to uh ground station coverage and it is it is a little bit tough to hear we just heard though that we got four good leak checks on their suits and now they're going to be in this final suited pre-bath so again this is going to last about 19 or so minutes uh and this is just to do kind of that final get all of the excess nitrogen out um and we started pre-breathe just two two hours after they got on orbit just like you know gradually lowering the pressure and I mean pre-breathe that that's something that kind of evolved over time with the space station where where were we when you were doing your space walk yeah so we were past the kind of the camp out phase of free breathe um but that's how we used to do it and it's very similar to what what the Polaris da crew has been doing over the last couple of days we'd actually have uh astronauts stay inside the crew lock overnight at a lower pressure just like they did when they first got on orbit now we've moved on to we do it the day of it still is a long day we start about 6 hours prior to going out the door uh but it's not 2 days prior it's worth noting uh along the lines of training and how the crew prepared for this mission that all four of our Polaris on crew members uh and some additional Polaris and SpaceX crew members actually went into um a a vacuum chamber and tested these suits out and spent uh a bit of time at lower pressure just to help learn what that feels like and get used to it well and I think the other thing that's important about that is it's real right it's it's the first time that you're in that suit and it's actually a vacuum around you right and there's just something mentally that I think is important to put people through those moments have to experience the first time in space yep we we saw some of the unique ways we train the crew for this and I mean training for space station space walks I'm still really upset I never got on the pool uh that looks like one of the coolest like parts of being an astronaut is like not being in space but just doing some of this training yeah Dan I I I tell you I can still remember the first time I stuck my head underwater not in the in the soup but in the for diet but you can hear the calms of of everything that's going on through the water like that and it just gives me goosebumps to think about I think about that it was a really neat environment but it looks like these guys had a pretty neat way to train as well with the uh the the harness that would hoist them up and out and and all of that that's that's pretty impressive yeah um we definitely created some rigorous uh new training for the best we could simulate an Eva while still on Earth um with hoists and uh you know it was um it was a lot of fun to watch them train back on board with cameras in 3 [Applause] minutes so our C just called up we'll get we'll get views back on board in about 3 minutes as Kate talked about earlier we're using ground stations for our video coverage all of our communication with the astronauts are through tedris so tracking a data relay satellite we'll have constant audio but that video we need those ground stations uh but right now they're just they're in that pre-breathe uh that final pre-breathe still we started our space walk about 13 minutes ago when we initiated O2 flow to the suits the time was 3:12 a.m. Pacific 12 1012 UTC I did some quick map took me took me 13 minutes to do it but I did it um so we're once they're through this pre-breathe we're going to start getting into to some really exciting parts of the Space Walk and and then after after we get to the pre-breathe we're going to get to cabin vent so you know what's what's go through your head when you're like man it's happening the A's going out it's really happening it's happening yeah I I tell you it is a long process to get to this point right they've been prepping for this for two days right and and one of the hardest things I found about the space walks is the waiting hurry up and wait hurry up and wait right you are so ready to to go out and to do this Mission and and to go out that hatch and it just takes time and I think that's one of the things you talked about my fifth versus my first you're fifth you kind of understand how long it's going to take you have a better appreciation for how long it's going to take and so you literally find yourself in these moments when when you're kind of waiting through this preg greed or you're waiting for the airlock to depressurize just kind of find yourself just floating there kind of zoning out trying to keep yourself calm and relaxed and and until that moment when it's it's game it's game time yeah now just a quick mention we about a minute out until we uh get those views back uh inside the cabin um um The View that we had previously was our Dragon tracker which uh if you want to see where Dragon is you can actually look that up as well um we have it on our website spacex.com slf follow- Dragon um but yeah just as a reminder uh our our crew they are in their designated or well Jared's not but um the yeah um our our crew members basically Sarah and kid have switched their seats for the Eva um we saw we last time we were able to see inside the cabin we saw Jared awaiting um to open the hatch so he wasn't in his Commander seat but uh Sarah is now sitting in Scott's pilot seat also known as seat 3 um and then Anna is on the far left side and Scott is on the oh yeah we can see it there on the far on the far right side um and also just a reminder uh their their call signs for these Eva operations um Anna being support two kid being support one and then Sarah being ev2 and Jared ev1 representing uh that Jared will exit first uh do his activities which include just some Mobility testing of the suit uh and then Sarah will go out and perform the exact same uh testing once Jared comes in um meanwhile uh kid and Anna will function as the eyes and ears uh they will be performing uh their own uh list of operations during uh or their own list of tasks during the Eva so while Sarah and Jared are going to be the ones that are you know partially egressing the capsule once that uh forward uh door is open uh kid and uh Anna will also be performing an Eva in their own right that's right and we talked about it earlier first time four people exposed to the vacuum of space like that's there's a lot of first in this that's going to be a really cool first not just for us and dragon um but we are going to be getting views back really soon we're again just in that final pre-breathe step right now and then we're going to start venting uh venting Dragon down to near vacuum so we're going to have a couple of different valves that are going to open up and the atmosphere inside dragon is going to start going overboard out into the vacuum of space now the crew the ground they can control they can pause that cabin venting if they need to uh we can pause and resume the most likely reason is for ear Equalization is again you're you're going through a lot of pressure changes anytime time you do a space walk and so if you've ever flown on an airplane and your ears popped you've experienced just a little bit of what they might be going through right now uh once we start cabin venting uh if we terminate or abort that the spacewalk during that venting we cannot start again we talked a little bit earlier about how consumables are like the thing that really drives you uh and for us we don't have a great big airlock with this with you know a full station worth of oxygen and stuff like that um so bre complete confirm rting [Applause] [Music] at1 [Music] go copy initiating Caron venting there we go that is great news so uh that breathing of increas that pre-breathe where they were breathing increased oxygen we just heard that uh they're good they all all four crew members gave the go uh so now we're going to vent the cabin yeah and in total this will [Applause] take in total this will take about A8 minutes and you can this the graphics you see in your screen that's live Telemetry everybody so you can see the pressure inside Dragon starting to tick down you're going to see the soup pressure tick down as well is what we're really trying to maintain is a pressure differential and so with these suits we're going to be hovering right around five or so you might see about 4.9 to 5.1 5.2 um it'll be about 4.9 and then we'll probably see it go up a little bit uh when they reinitiate the secondary flow yeah Dan and you talked about that about five PSIs what the suit will be we're actually a little bit lower in the Emu yeah and so we've talked a lot about Mobility that difference between we're at 4.2 and they're going to be at five it can actually make quite a bit of difference just in how hard it can be to move the suit around Etc yeah this crew got to and that's something we can simulate you know on in a vacuum chamber or even just uh in 14.7 you can you can simulate that that differential pressure getting calls from the crew they're they're monitoring along1 good we're going to hear that kind of we're going to hear that chorus pretty frequently where you do those kind of frequent most like checkin and I know you guys did something kind of similar where like you would have to pause and you know check your gloves that kind of stuff we we did I I will tell you one of the interesting things watching this uh live right now the difference is how quickly the depressurization is happening here versus uh what my experience was and and so you talked about being able to clear your ears and all that you're not giving a lot of time for your you're not giving a lot of time for your your ears to adapt to that lower pressure so this this is seems pretty quick to me yeah break breaking new ground with this new suits new operations for everything we're at about 4.5 we're going to see that tick down it's going to get down to just under one and it's not going to go all the way down um and then what we'll actually see is we've got a capability to open the hatch automatically we got a motor in it um but Jared's actually going to unlatch it and he's going to give it a little tug to kind of break the seal break any of the kind of the stion in the hatch itself and that's going to kind of take the capsule down to its final vent before Sarah who's at the displays she's going to command the hatch to actually open um yeah that's a good point and you know there's there will be slightly more pressure inside the capsule so really just helping pressures look good copy four so Jared really can't open the hatch all in one fluid motion so we will see him uh release that that pressure slightly um before being able to open it completely and I think one of the important things you guys I think had talked earlier about you put some more um restraint devices inside the capsule from when I flew on it and that's extremely important because there's going to be some force that Jared's going to have to be pulling down on and he needs to be able to Anchor his feet somehow um otherwise he's going to pull and it's not going to go anywhere and so the the new restraint devices in there we're going to see how important that's going to become here when he tries to open that hatch yeah yeah that's that's one of the things that's why we have Skywalker out there we've we've talked about how kind of similar to to Gemini when they were first kind of stressing their legs but important to remember we've got that 50 or 60 years of space flight history that we're able to draw these are new suits this is a new operation this is to you know work out all the Kinks and really test this for the first time but we're going into this with a whole lot more information than they had back then we know you need handrails or it's going to get real hard real quick that's right that's right yep we did we did also here uh dragon's moving into its uh its Eva orientation essentially we're going to the trunk at the sun under 3 PSI I think it's also interesting you notice that the de pressurization has slowed down a little bit right so as we get to this lower pressure it's it's just taking it longer for that remaining little bit of air to to uh go out through the vents an ev1 come Che you want mad and mad and well also hear the Vox starting to adjust its levels that that flow of oxygen has not stopped but the microphone's kind of adjusted and it's getting a little bit clearer and yeah keep keep an ear out you might hear their voices start to like tener down a little bit I do think that's a an important Point Dan that how important Comm is yeah right and and when it's compromised a little bit just by that extra air flow in the Vox not keeping up with it right away uh how challenging it was just to hear those calls and they can be some pretty important calls so of course uh Comm is is just critical we can see Dragon capsule now approaching close to 2 psia like Dan mentioned earlier that's going to get to just under one it's incredible to think that uh you know the Dragon capsule in all its power and glory and awesomeness the the new capsule is around their bodies right that that is what is going to protect them um from the vacuum of space and uh you know just seeing how even though it's puffed up and we know that it's uh you know holding that pressure it still looks so cool for lack of a better word one's good good one good two good yeah you really have four mini space or spaceships in there prsi guess that means we have four aliens in there too that's right Dragon SpaceX L than 1 psi from hatch operating pressure we have a tedris Handover in two minutes we are going to wait until after the teacher hand over to command in Hatch open [Music] prep one copy and yeah I think you heard that the the tedris Handover so there's going to be a a short period of time there where they're out of Cal and we're at it's kind of interesting because we're at a very critical phase ah as well and so you want to make sure you have all the data and uh and the ability to talk to the astronauts before you actually take that next critical step we'll see it we we're seeing that pressure Contin need to take down Dragon originally designed to be able to still operate in a vacuum that was some of the emergency situations I know you trained for Mike we did make some modifications to this one uh to essentially turn Dragon into a functional air loock um we added some additional uh vent paths um we do use like some of the same ones that you guys use to like pressurize the vestibule and stuff like that um that are actually in the hatch but we've got a we've got an extra one in there to to be able to essentially do that deess as quickly as we did but we're going to we're going to see that get down to a little under one and then we're going to see Jared kind of jump into action he's going to unlatch the hatch and then he's going to give it a little pull to break the initial stion and then we're going to be able to uh see Sarah csia all want C now it's one thing to note that while we have been progressing through this pretty quickly we did have the capability to pause if any of the four crew members needed to uh you know take a moment to you know let their ears um come to equilibrium or just kind of get comfortable again um we did have that option but everything has been going really well so far we haven't had uh to to pause cabin venting and if you're just tuning in heck of a time to do it we're about a little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of these crew members that was at 312 Pacific 1012 UTC we did heard that dragon's now in its Eva attitude [Music] complete so again we've got we've got dragon's trunk pointing toward you on board watching through the cross [Music] view that was SpaceX core Arthur baralt just letting the crew know uh that we're the cameras are on inside and uh basically which camera is is looking at them it's it's so fun to hear Arthur's voice because he was actually a part of our mission as well in fact Arthur was an intern started out as an intern when we were first uh starting the and and so now to see him as a as a core and uh is is pretty neat very similar to Sarah who also started as an intern yes yeah right we're coming up on one PSI you might see you saw the light change a little bit through that window is we're in our Eva position trunk facing the sun that's going to help us with thermal uh inside the capsule and on the cruise suits also going to make sure we're maintaining that that optimal pointing for communications with the tedris satellites uh once the hatch is open we're going to disable any of the Draco thrusters that point forward is you don't want thrusters firing off when a crew M's outside we're at one you can see the suit pressure is ticked down too there's about 4.7 difference between the suit uh and the ambient cabin there in dragon that umbilical that you see there uh just to the side of Jared that will continue to flow the air into his suit as well as provide Telemetry and Communications connection that's also where we have the um safety harness built in as well so it's able to Dragon SpaceX cab pressure below hatch operating limit standby for transition to hatch open prep here we go Mike did you get to open the hatch I did you did yes yeah when you when you go out as uh hatch open prep Dragon SpaceX for Ev hatch open prep confir K to open [Music] hatch that is great SpaceX copies Dragon you are go to open hatch go excited space go to open the Hat Mike as you mentioned before that continuous communication [Music] handle as you can hear we do have a crowd Gathering outside of Mission Control uh here in hawthor in their excitement somebody dropped a cup we can see our commander Jared isaacman now turn in the crank which allows the uh that top hatch to open we'll see him give it uh a pretty heavy uh1 hatches Vis indicated open he copies stand [Music] by should see him give that hatch a pretty strong jolt to release that stion hatch is now unlatched Mike talked about we see him getting his feet getting his feet set that's right Dan You' ask if I got open in the hatch so when you go out is ev1 just like Jared here is ev1 that's that's typically the role for for you is to open that hatch and you guys have to draw straws whatever get it's exciting it is it's very exciting yeah now for those of you that have just recently joined as you can see we have success y depressurize the Dragon capsule uh down to Zer psia you see that in the bottom left hand side bottom left corner of your screen um our four polaron crew members um have uh gone through the uh O2 flow and we see Commander Jared um isaacman now standing by uh to open that top hatch the nose cone is already open it opened just shortly after uh the crew got into orbit uh so Dragon Space X Target pressure [Music] reached Space X I'm oning the hatch now Jared now opening Dragon resilience into space so we saw some motion on the hatch again he's just giving it kind of that initial tug and then Sarah it gets to push the button to swing that hatch [Music] open much more movement there on the forward hatch this must be pretty exciting for Jared because that center part of dragon Space X that's a good brace we're going to have you repeat the operation center of the hatch actually has a window the hatch is unseated copy give it [Music] another hatches s in copy we see it looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes Dragon Space X complete ev1 return to seat [Music] then E1 copy transitioning back under the display so again one of the reasons we had Jared do that was to Dragon SpaceX we're actually watching that hatch we're going to have you repeat the last operation sounds like they're going to have repeat him one of the reasons we're doing that is just to kind of vent any of that residual under this and ev1 you are go for manual hatch [Music] open sounds like we got our first audible of the day as we said that we can open the hatch open the hatch man we could open the hatch man we could open the hatch automatically or we can do it manually and so they just gave Jared the go to open that hatch manually so we we just went out of ground station reach so we'll get the views back wow we'll get the views back real shortly uh and then the the hatch will get see hatch open and hopefully we see it yeah hopefully we see a hatch open hatch is openx copies hatch [Music] open that is fantastic news uh for those that1 I'm looking at for seals initial view looks pretty good don't see any bers oration copy on Hatch report yeah that seal that you just heard him talking about it's such a important part for the end of the Eva right so that when they close that hatch again you get a good get a good seal X can you command open forward hatch we're going to stall it open there is our first view of the forward hatch wide open space if you just jumped in we are 38 minutes into today's spacewalk and the hatch is open on Dragon first view from a helmet cam looking out Dragon Space X we see installed ev1 is go to [Music] continue that structure you see there is check for [Music] ER I'm back from under the display SpaceX copies we with you in your helmet cam once again this helmet cam what we that structure we see is the the space walker this is Jared now egressing through the forward hatch of dragon resilience the first views of the first ever commercial spacewalk I'm at the bottom of the mobility a progressing I have a feeling the crowd is about to go wild there f back at home we all have a lot of work to do but from here bir sure looks like a perfect [Music] Road one I'm going to

with live [Music] video Cy [Music] that and for your awareness Max re8 and the mid Bar M test Matrix 2 is complete C readout 5.3 PSI 33 decimal 99 Celsius % RH copy test Matrix complete and hard read up check e1's good good good stepping in the test Matrix three three demonstration ev1 Space X for Ingress [Music] time go Space X recommended Ingress time of 02 flow plus 4 7 minutes [Music] got the G Time 4 S minutes and dragon we're back on live video from the [Music] noon happy that space [Music] and space atv1 I would say the handsfree demonstration is very comparable for the trainer in terms of the foot [Music] restraints space copies and ev1 when you have time if you'd like to return to the reach demonstration uh we'll take a look at that with the live video [Music] after that test Matrix 3 is complete the H read out is 5.3 PSI 47% R 33 decimal H CSI and stepping back into to Max reach copy test Matrix see top of the mobility Aid and uh let's get a Quick Crew off check e want good May good I'm good good happy that okay uh Max reach whether it's left or right hand seems to be about the same toit the mobility Aid and then the midr copy we see Che up on the [Music] bottom any go back St negative we got about 1 minute until ev1 Ingress have 1 [Music] minute [Music] gorgeous you want to see guys get right ev1 we're checking out your helmet cam [Music] now now I'm checking out your nose con right now and it's pretty good cop we're Turing those see looking at [Music] us all right we're coming up about that 024 timer time two check for inra E1 good e all right St ja one that's for the huge steam effort that have suppos to get us to this point we know it's just to start then I'm transitioning back in the vehicle [Music] [Music] [Music] face at TV1 we taking a quick look here into the hatch field from what I can see so far they look pretty good copy on the hatch seals and standby for transition to read off [Music] reset def face okay good and ev1 is clear [Music] [Music] all right so Jared back inside uh we we heard him going through What's called the test Matrix uh it's basically just a bunch of Maneuvers using different hands using the foot Mobility is inog calling out numbers right now though we're doing you just heard cop Arthur call up three off resets so we didn't use any of the forward thrusters while Jared was out there we're re-enabling them putting us back on our perfect attitude before Sarah gets ready to go out the door fun thing to note it's still not a perfect vacuum inside a dragon is it's an open loop system so oxygen is kind of getting dumped into the cabin as this is going on so you got a higher pressure in Dragon than you have outside so we're not worried about Thruster pluming yeah now you mentioned Sarah um just like Jared she will have 10 to 15 minutes uh outside perform those same sets of Mobility tests as Jared uh like we heard the core do um with ev1 uh they will call out when there's one minute remaining uh reset complete ev2 go for [Music] erress there is Sarah's clear crew check for Ev e ev1's good ev's good good two good Ed is going to go stand on the door and then step outside now this test Matrix that uh Jared just performed and the one that Sarah's about to perform they have both committed to memory um in order to execute these um we saw it being done pretty efficiently I can't believe how quickly that time went by Mike we were talking about how your Spice Box for hours and these guys only have 10 to 15 minutes and it just like that yeah it it can go pretty quick and uh but fortunately um looks good I see a little bit of a bulge between 14 and 13 so you're hearing Sarah call out some more of the seal check there as as she's exiting out three feed SpaceX copies that report good fix so this was something we knew might happen um and between 28 and 27 [Music] copy the crew trained on exactly what to do in the scenario just pop it back in one final between 19 and [Music] 18 but might be best re get hatch closer SpaceX copies can you repeat the location EV complete between 19 and 18 all right copy I'll track that and uh ask again when you're [Music] in copy P2 is proing with e super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her Space Walk e one I'm going to hand this back to you like we mentioned Sarah will be performing the same uh set of Mobility tests uh so we will do the same uh try to stand by listen to this C I mean I said it before a lot of us we characters we want to do this all right stepping into test just one for single-handed Mobility really cool to see one of our own out there that's awesome and ev2 for awareness we're watching from the nose conon and Cy all I just say in all three translation AES I'm having certainly cross movements forward back aming the B ever roll s it's left right and up down a bit of a titch but all keepable rating is three y the three four and PES the food [Music] than for for left man stepping into vertical [Music] translation SpaceX copies and ev2 for awareness we're tracking an Ingress time at the to flow 59 [Music] minutes Cy 5 9 Minutes horizontal bars are definitely preferred and I'm adequately able to stabilize my body with single hand disturbances for us left and right stepping into M reach do you have visual a firm we have visual on the nose [Music] cone copy from bar four to Bar two from top down and S reach from bar two up to Bar four SpaceX copies reach and e testing one complete SE pressure 5.25 33.8 Celsius 37% humidity SpaceX copies HUD read out and test Matrix one [Music] complete copy 7 two like we mentioned before views going in and out doing during excuse me to those ground station uh coverage gaps yeah we we coms some of the same comms are through satellites but we've got ground stations for video on dragon as you can see in the tracker we just flew over on New Zealand we're about to go right over the middle of the Pacific no ground stations in the middle of the Pacific are actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got she got about a minute left and then she's going to start heading inside and see if a little more work I can actually get between almost bar one and bar four on that stre space has copies and you could see the Earth dark and we flew into like an orbital and test Matrix to kind to combine them so we'll call back conce PE pressure 5.27 38% humidity 33.7 Southwest SpaceX copies Matrix complete and HUD out steing into handre demo are able to engage and disengage my feet copy that2 and once you are able to engage disengage we'll actually have you start Ingress we're just over 5 9 Minutes O2 flow Cy thatting at in check for in good 14 goody coming on in all right and just like that Sarah's going to start making her way dark clear check those hat seals again SpaceX copies on strier plates and ev2 I have one more ask for the hatch if you can uh checked out as well when ready to [Music] copy ready copy copy and ev2 what I'll have you do is when you Ingress can you get eyes on the hatch handle mechanism and see if the handle has been stowed in the Do Not Stow uh window and report if you can see that check I think it's just outside copy just outside thank you just outside the range and for awareness I do see a couple of those same points folding again between 12 and 13 copy your go no mostly between 12 and 13 right now SpaceX copies at 12 uh if you can you're go to those C and these numbers being called out represent the location around yeah the location around the circular hatch just identifying where these bulges are so Sarah is now reaing that seal not quite able to reach the bathroom so we'll proceed with clearing perap closure just like that we're already hearing about hatch closure it's incredible that these two Evas just in two blinks of the eyes are uh isar on your screen there is SpaceX core uh or crew operations in resource engineer on duty tonight is Arthur baralt this is the uh the voice to the crew throughout uh their operations of course you know everyone has to sleep so we have different shifts for core um but Mike your time and dragon driving close you're good Cy the handle let F and forth I'm closing once we get ground station coverage uh again we will be sure to bring you views within the Dragon capsule but right now Sarah is closing the forward hatch it sounds like we might give the motor a try he confirmed the hatch is visually getting Clos Comm hatch is verified L hey command Eva hatch Clos Eva hatch closed all Dr thr is enabled Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress one and E1 copy goodone check secondary O2 valve Closing one I'm good T1 close 82 CL one two [Applause] close so couple of real big moments right there Sarah was able to make sure second is closed and agree EV press one she was able to make sure that the seals were in good spot we got the hatch closed you can see a half PSI for 8.3 see the pressure starting to TI up just a final confirmation everyone confirmed secondary O2 Val are Clos keep1 close close CL 14 G and we're through one for 8.3 all right so each of the crew just closed those secondary O2 valves on their umbilicals again that was primarily for cooling um during the space walk itself suit still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon right after they get the hatch closed they're able to do kind of an initial pressure check cuz again oxygen it's an open loop system with the suits still flowing into the cabin you're able to see positive pressure response showing that the cabin uh the hatch was closed and was sealed uh we'll still do a leak check on our way kind of back up to our nominal cabin pressure um so we're going to continue ticking up until we're about 8.3 PSI and then we're going to transition into the second phase of our repress um really the difference between repress one repress two is how frequently we're injecting atmosphere uh as kind of the the repress is also pretty unique with dragon um we're repressurizing with just nitrogen right now um which is a little bit unique obviously you have nitrogen and oxygen in your atmosphere uh with this we have O2 flowing into the cabin through the suits so we only need to add nitrogen so we're able to just basically add a bunch of that to really start getting your pressure up O2 continues to flow into the cabin through the suits and we're going to continue pressurizing until we're pretty much right back at our 14 right about our 14 uh or so PSI and we're also looking at what the partial pressure of oxygen is cuz we want to make sure crew takes helmets off and everything that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is micro gravity everything's harder everything's on hard mode um and you don't just have natural convection so like I mean space station I think I've heard it a bunch of times Mike like you just constant noise of fans that's right almost yeah there's uh you've got to continually recycle that air um and one to help get rid of the CO2 right because as we're taking in that oxygen they're breathing out the CO2 and we need to to get that out of the system which is another important reason to have that air constantly circulating yeah um man that felt really quick that it did that was that was that was really cool to to see them outside for the first time and there they were what they were actually doing out there is a bunch of pretty simple tests as it looked but like this is just learning how the heck do you move cuz like just moving around yeah in micro gravity is tough it is tough Dragon Space X were about 2 and a half minutes from T's hand around when you're in your short sleeves like we're in inside the capsule and when you put on that spacit uh it it's much more challenging to to move around with that on yeah and what they were really doing was just kind of like you put your hand on on Skywalker and then you're changing your pitch you're doing translation up and down and everything and then the one that that I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah and I think one of the other things I thought was interesting is you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab on to or utilize versus the vertical one so simple things like that you know for us it not a big deal yeah uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that you'd be able to with us throughout this's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all of SpaceX and and really for for Humanity because it's just one of those small steps that's taking us that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime excellent all right good to see you thanks byebye all right so repr is continuing we're a little over 4 PSI right now again we're going to keep that going up until we're a little over 8 and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole process like right after we got on orbit yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their cute Zerg indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and uh let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there coming in the the teus in and out so like we'll get it back um so yeah just the fact that the uh all four crew members were able to just go right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during one you good we're good you kid just heard a quick check-in from them so we're going to keep keep counting the PSI up until we get to about a we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduce atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at eight and then we'll let it hang out there for a couple of minutes I'll let the thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is fully recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressure is starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for 1 hour and 13 minutes um it flew by so so quickly um on cabin pressure approaching one PSI on PP I'm I'm sure for shared and Sarah flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core Arthur barrial that's going to come uh once we are done with the repress repress operation uh we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the pure2 environment in the suit using Nitro before they get out Nitro being that same air mixture that you have in your scuba tank uh if got any Scuba ders out there uh that nitrogen oxygen mixture um nope still still just there we're just going to keep ping out should hopefully be getting video back from ground stations stand by for transition to ress 2 at 8 decimal 3 okay copy SpaceX we're following along refes two at 8.3 and so once we transition to repress 2 once we're at about 8.3 I will stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of a let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we've got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hopefully just about a minute and a half or so away from ground station so might get those views back inside a dragon I yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh pause refres to through che1 and yeah that coms we're hearing PS before we get the Le check check 9 have a continual checks with all four crew members to make sure that everyone is good um if the answer to one of those checks was no there would be an option in this repress sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depress eyes now this repress seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to tick up we're going to pause at 9: we're going to do another cabin leag check so we should hear that momentarily time Eva refres to stop driving space with you in Eva repress 2 stop waiting 5 minutes for theral stabilization we're that we're tracking Pro for your awareness we do a positive refresh R we are 30 seconds into the reck like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness pp2 is one decimal 35 halfway there suits are still flowing that oxygen um and in a few minutes we will begin to flow we'll do a flush uh of of nitro uh into the suits all right we got our views back there they are it's a little sad to see that forward hatch closed again it's it's got to be really hard when they tell you it's time to go back in yeah just one more minute y reminds me of when I was a kid swimming in the pool you know time to get out just one more a minute I mean it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline minut into 8 Le what you cp2 just passed 1.5 we're a couple minutes into our leak check you're you're seeing the pressure continue to tick up we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that is why you're going to continue to see the pressure tick up you heard Jared call out the po2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14.4 or so and I mean that's that's a little bit lower than what we're walking around in now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that nitrox uh the K was talking about uh that takes them out of that pure oxygen environment and that's one of the final steps before we'll he hear that call from Arthur evva operations complete and that's when our clock's going to stop uh our space walk did start today at here at SpaceX in Hawthorne California and I'm Dan huitt from the communications team now the first Eva in history was performed in 1965 by Soviet Cosmonaut Alexi leonov followed just three months later by the first American spacewalk done by Ed White during the Gemini 4 Mission from those humble beginnings to walking on the surface of the Moon repairing satellites building space stations in orbit space walks are really a core component of human space flight well Eva are wellestablished procedures for NASA and other space agencies this will be the first Space Walk using commercially developed hardware and procedures and spacex's brand new Eva suits which we debuted earlier this year now we've tested extensively in vacuum Chambers here on Earth but this is the first time that the suits will encounter the vacuum of space and onboard the dragon spacecraft right now is the Polaris Dawn crew starting off you got Mission Commander Jer Rook isaacman Mission pilot Scott kid potit and for the first time ever we're excited about this two SpaceX employees Mission specialist Sarah Cooper Gillis and Anna Walker Menan who's serving as the mission specialist and medical officer for members of the crew have been orbiting Earth for two days since they lifted off from launch complex 39a at Kennedy Space Center on Tuesday September 10th it adds up to about 15 to 16 orbits around the Earth every single day in County on day two of the mission as you can see there on your screen Dragon fired its forward Draco bulkhead thrusters to send the spacecraft soaring higher than any dragon mission to date reaching the highest Earth orbit ever flown the crew uh topped out at more than 1,400 kilom breaking the record set by gmany 11 a half century ago when that spacecraft reached 13 excuse me 1,373 km this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 since that time dragon has gradually lowered its apog or the highest point in its orbit as the crew got ready for the space walk today they started to Dawn or put on their Eva suits just a little bit of time ago and they've been undergoing a process called pre-breathing where the atmospheric pressure inside dragon is slowly decreased and oxygen is increased to prepare their bodies for the Eva suit environment we're going to dive more into the operations of the spacewalk a little bit later and we're going to be hearing in live communications with the crew throughout so be sure to listen in as those happen yeah it's going to be super exciting to hear that and as far as views goes we'll have dragon's regular internal cameras that we have seen before and up to three external cameras one aimed at the hatch uh kind of like what you see there uh one on Dragon's nose cone uh which actually is the one that's there that's the the the camera on the nose cone and one on the newest piece of Hardware that you see there in that view we that is the Skywalker um which we will come back to shortly we may also have helmet cameras that will give us a firstperson view from the crew which will be incredible now since we are not using starlink to uh enable views today there will be moments of expected loss of signal due to ground station coverage so those views may be interrupted from time to time but generally we expect to get some great shots today and as of right now we're less than an hour away from the start of the Eva for now though let's learn a little bit more about the mission and our crew the Polaris program is a first ofit kind effort to rapidly Advance human space flight capabilities while continuing to raise funds and awareness for important causes down here on Earth today's goal is to demonstrate critical operational capabilities that are going to serve as those building blocks to help further human space exploration playist Dawn Mission has a lot of firsttime objectives so the L's program chose a crew of experts who know each other so they can tackle this mission's challenges as a team first up Mission Commander Jared Rook isaacman also served as the commander of inspiration for the world's first all civilian mission to space Jared holds several world records including two speed around the world flights in 2008 and 2009 for the Make A Wish Foundation he has flown in over 100 air shows as part of the Black Diamond jet team dedicating every performance to charitable causes in 2011 Jared co-founded what would become the world's largest private Air Force dren International and that trains Pilots for the US armed forces in addition to his role as CEO of Shift 4 Jared is an accomplished pilot and astronaut with over 7,000 flight hours next up Mission pilot Scott kid potit who served as the mission director of inspiration 4 and he goes by the nickname kid which is also his call sign he's a retired us Air Force Lieutenant Colonel kids served for 20 years in roles that included commander of the 64th aggressor Squadron Thunderbird number four demonstration pilot US Air Force weapon school graduate operational test and evaluation pilot and flight examiner he's a command pilot with over 3,200 flying hours logged over 400 hours of combat time and following his Air Force career kid served in various roles including vice president of strategy at Shift 4 Mission specialist Sarah Cooper is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew one missions and most recently directly trained the inspiration for astronauts Sarah is an experienced mission control operator who has supported real-time operations for Dragons cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for dragon's human spaceflight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program full-time and capping off the Polaris Dawn crew mission specialist and medical officer Anna Walker Menan who serves as a lead space operations engineer Hubert SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragon crew capabilities and develop critical operational responses to vehicle emergencies prior to SpaceX andna worked for seven years at Nasa is a biomedic flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going to space that's clear but let's take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isaacman I'm Scott kid potit I'm Sarah Gillis and I'm Anna Menan and we're the players Don crew I Love This Crew I mean all of them are just so hardworking so smart kid po over here is our mission pilot talk about a career in the Air Force doing every job as a pilot that that anyone go is fire to achieve and having somebody who has you know been there before and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always there glue glue you are always there predicting what every person needs um and he's needy what our commander Jared I think he is incredibly sharp that's right so something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical confidence we don't get out of any engineering update or brief or go through a procedure or debrief without getting into the weeds and making sure every tea is crossed every guy is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared that served her in her role as core it serves her in her role as a trainer Anna you have this incredible joy that you bring to everyday life it is infectious it makes us all smile feels like she always has this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then the biomed engineer and a background like that inspires like a ton of confidence that you go up there if uh if people aren't feeling right that she's going to be there to take care I cherish all the moments that we've had uh in these experiences and uh we're just so excited to to go to space now that you know a little more about the Polaris Dawn crew let's recap the mission so far and what's coming up next since liftoff and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours demonstrating the Eva suits pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I mentioned earlier on day two Dragon proceeded to a high apogee of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the spacewalk dragon has been executing a series of a apogee low apogee lowering phasing Burns by now dragon has lowered itself from the highest apogee of the mission of more than 1400 km to about 190 by 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude Children's Research Hospital um and they they're joined Live While polaron crew member Anna Menan read from her new book kisses from space along with the patients and families at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the Polaris daon crew Enlisted the help of Childhood cancer survivor live to create the missions Zerg indicator while not a St Jude patient herself live met the inspiration Fork crew and inspired by the mission of St Jude she agreed to share her talents to support pois Dawn is live and I spell it l and then an apostrophe mark exclamation park I can tell you anything about space from the miles from Earth to the Sun to every Mission basically I had cancer in 2021 cancer survivor like Haley I really have a passion for wanting to help St Jude and other kids who have those struggles as I had so I first met Liv a couple days after I got back from space at our Splashdown party and I got to meet her family and they told me about her journey that she was on I remember that she gave me a card she had written and it said thank you for helping other kids with cancer like me I hope to go to space like you someday and my eyes just filled with tears whenever I read that basically my one passion is to um be the first child in space Liv was really close with the players Don crew and they asked her to design the Zerg indicator a zg indicator is like a little FL toy that floats in the air it basically shows that you're in your they kind of hide it over in the corner and then once you hit theg it'll float up and reveal itself my main idea for asteroid is based on elon's dog py I I've always loved sheas they've always been really cute and then when I heard got POI I was like done I love her I want asteroid to be for every child and help them see oh as went to space and I can too I can achieve my [Music] dreams we are also flying Liv's original drawing that you see there that was used to design the Zerg indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital all donations from the sale of asteroid will will be General donations to St Jude the inspiration 4 Mission helped raise more than $240 million for St Jude Children's Research Hospital and polaron will continue to raise funds and awareness for St Jude while partnering with the organization to provide Health Care in underserved communities around the world now if you want your very own asteroid they are available at shop.ace x.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the so be sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got I snagged one I got in there I got a kid who nice needs one yeah all right now the first phase of the spacewalk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre-breathe process started that's when the oxygen levels started to increase incrementally as the actual the cabin pressure side Dragon was started to get incrementally lower the pre-breathe process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any space walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure of in deep water back up to the surface and to do all this D Dragon just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in in the suit during the spacewalk itself they've got the ability to pause the process if they experience any discomfort but the ear ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude on an airplane um all four astronauts are going to be suited for the space walk today cuz Dragon does not have an airlock that's also why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with the stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah are just going to be lightly secured ahead of the spacewalk since they're going to be moving around and eventually heading outside as we listen into comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support two is Anna again they will not exit the dragon during the Eva but make make no mistake they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rotate those upright during the Eva just to give more room to move about after that seat rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tabs in the health of their suits and they'll get some other stats of their suit operation during The Space Walk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations brief from the SpaceX team the crew will announce their go noo status and then it'll be time for The Space Walk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the crew suits until we complete the repressurization of the cabin and just prior to we get to cabin venting oxygen is going to start flowing to the cruise suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the sun this will help keep temperatures Communications and spacecraft power stable during the space Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during the spacewalk he's going to be the first to exit the spacecraft he's going to go outside and he's going to do a series of Mobility tests these are kind of the core component of the spacewalk today it's going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into Dragon after that ev2 or Sarah will step out into space to perform the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit and then after she's completed her test Sarah will stand by near the hatch for the actual closing and then at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is suited up and awaiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the Space Walk and before we get there though we're going to expand the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back here in Hawthorne with you tonight on this uh very memorable night for sure yeah absolutely uh now Evas may be new to SpaceX but uh you have participated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two missions you the first one was back in 2013 and I uh I went up on a Russian soy use and on that one we had two space walks and the interesting about those spacewalks is they weren't planned uh they were what yeah they were a big surprise for us uh contingency Space Walk and of course surprises happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a space walk as everybody was getting ready to celebrate Christmas down here helping deliver presents that's right that's right and then your first play was on the so but your second one you were the commander of crew one I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than than anybody cuz you you actually got the call at home while you were docked up there that's right it I mean I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was an a great amazing group of people not only uh uh Victor Shannon and suichi but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough Cruise stations and actually you can see a picture of uh of where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the station where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the spa get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for crew one weren't they they were yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees and somebody else getting to uh getting to test them all the time so uh yeah it was pretty neat to to get to see that switching it up a little bit cuz we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to, 1400 kmet uh we like to talk about something called the overview effect so kind of that first that oh and we're getting some CS from our crew too yeah I'm nice spaceex dragon radio check c l clear kid H me C you loud and clear dolphin continues unless just got to be right captain that make that Don all right some some quick com checks we heard kid that Scott po he's going to be one of the support crew in there today so our first calms down as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back and I mean you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overview effect is definitely real but when I first got to space um on that on that soy use uh gu how many years ago almost 9 years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now this really that's pretty but oh no um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you'll hear people talking about that that small sliver of atmosphere here and you you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me a lot of questions it made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it brought as many questions as it did answers hopefully a bunch of bunch more trips down right that's right that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank White originally coined the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feel feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habitable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different emotions that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moonrise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to Mars and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of space where four is next support two is next and then EV one and two are surely behind copy on that crew status getting a quick quick crew status from kid um yeah I I think I speak for a lot of space exors we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dragon and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean spacewalks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first space Walkers contingency we had a failure and so sometimes when we're going outside it's it's not planned and you have a component that that is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out we're putting a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar rays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Dawn crew is going to do today and you're just checking out the suits and checking out the equipment that that you're going to use in future spacewalks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um basic for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction requiredby actually uh if I can I'm just going to jump in on that that's actually very important call that was made you heard him say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around at what was that and so you heard them give them a warning that we're going to turn on some fans yeah and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those spacewalks where I was uh at you know outside and and what are you proud of you're you know it's it takes so much to put these vehicles up into space and and so when you go out on the spacewalks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because uh people are depending on you and couple of people watching over your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good stations back up 100% just like okay that's that feels great Dragon Space X are fan commanding is now complete tell all right hopefully no surprise sounds in there for him so I mean space walks are something that you you train the heck out of they they playing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a space walk yeah so I mean one of the first challenges that you're always worried about is the how your suits functioning right cuz that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground are monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between between you and the and the ground and so they're making all of those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about spacewalks that uh maybe people don't realize is you know you focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they ex the these space walks um they they you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk it no it never felt like a cakewalk at at all um you know because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely um very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on you're more familiar maybe as a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I'll equate a little bit of of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all of that kind of nervous energy as you're getting ready to go out well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on seat rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them upright that's just going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is spacex's 14th human space flight Mission since 2020 when Dragon became the first private spacecraft to take humans to the International Space Station it's also the first private spacecraft to take an all civilian crew to orbit during the inspiration 4 Mission in 2021 and just prior to Polaris Dawn Dragon completed 46 launches 13 of those are human space flight missions and it's since flown 50 astronauts representing 14 different countries throughout all of those missions dragon has helped support more than 1,000 experiments in space pretty incredible stats there um and even from low earth orbit dragon is helping lay the groundwork for deep space exploration through missions like inspiration 4 and Polaris Dawn we are rapidly expanding our knowledge of how humans will adapt live and work in space designed to be the safest spacecraft ever flown the fully autonomous Dragon stands nearly 27 ft tall and 13 ft around dragon is capable of carrying up to seven passengers to and front Earth Earth orbit and Beyond but today it's carrying the four members of the Polaris Dawn crew and the crew is currently living and working in the top portion of the spacecraft that's that white section that you see there also known as the pressurized section this allows for the transport of people and environmentally sensitive cargo below that dragon's trunk it sits right below the pressurized section that can carry unpressurized cargo on resupply missions and it remains attached to Dragon until shortly before re-entry into Earth's atmosphere and as you can see about half the trunk is covered in solar panels those provide Power to Dragon during the flight the other half is the radiator Dragon itself is equipped with 16 Draco thrusters we got really cool view of the four forward bulkhead ones firing earlier on this flight with lights on Earth behind you those are used to orient the spacecraft during the mission they also get used for apog and Pary raise and lower Maneuvers orbit adjustments and attitude control for the Eva the Draco are going to be used to reposition Dragon so the trunk is facing the Sun and they're also there to be used for reorientation during the spacewalk if needed in order to accommodate accommodate a spacewalk this is the first dragon to be outfitted with a Skywalker in place of the Koopa observation Dome the Skywalker that you see there looking up at it uh from the from basically from underneath it um the Skywalker is a structure that is mounted to the top of the Dragon capsule and the astronauts will use this to assist in exiting and re-entering the spacecraft during their space block the team also added additional nitrogen tanks to assist in repressurization of the capsule after the Eva another new feature on Dragon is the addition of a motor plus hand holds and footh holds inside the spacecraft to help with opening and closing the hatch during the spacewalk this Dragon also carrying what we are calling the starlink plug and pler this the first mission on Dragon to use the starlink network in orbit inside a dragon is a router connected to a user terminal in Dragon's trunk and then this terminal is linked to a new plug-in player device that's mounted nearby while we're not using starlink for continuous coverage during this operation we've been testing its ability to establish and maintain laser Communications with our starlink satellites there in orbit that are below dragon dragon has proved to be quite a versatile spacecraft it can autonomous ly dock to the space station when outfitted with the ISS docking adapter and when it's intended for free flyer mode the docking adap adapter can be swapped out drag and you guys are walking come on back aboard if you want SpaceX copies don't have uh ground station right now but we'll go ahead and bring cameras back on board so we get it when we do have ground stations quick comms there with SpaceX core uh from the Dragon capsule that was uh the crew just letting the folks here uh in Mission Control letting us know that it's okay to turn the onboard cameras back on once we have uh coverage for those cameras um but getting back to the different um configurations that we have for the Dragon capsule um I was talking about the docking adapter previously when the Dragon capsule is intended for freeflyer mode docking adapter can be swapped out for a Cupa uh which is the one in the middle there and that is used for the best views that you can get while in orbit and then of course our newest option the Skywalker Hardware to support extra vehicular activities and that's what the crew is going to be using this morning so those are the current three ways that dragon can be configured to support different types of missions but hey you never know what's to come we always got something up Our Sleeve right now Mike crew one broke the record for the longest space flight by a us crew vehicle surpass the 84-day mark that was set by an Apollo capsule during that final flight to the Skylab space station in 1974 what was it like because we we went over it you literally called Dragon home during that time what was it like to live in there so so first of all I got to say it's pretty exciting because uh the the dragon that they're using right now is the dragon that I lived in that took us to orbit uh yeah we affectionally called resilients uh and it was a it was an amazing spacecraft uh it it uh from a standpoint of living inside it and um again it it a lot of room actually compared to some of the other crew quarters that we had on board and uh and and plus just uh you know being able to to uh spend all that time in it you know I call my family every night before I'd go to bed and I'd be looking out the window uh at the Earth uh as as I was doing that it was uh very special did did any of them get jealous cuz you had the window seat well yeah there was a little bit that certainly uh going on up there nice now as you mentioned this Dragon capsule that the inspiration excuse me that the Polaris Don crew is flying in was previously used uh really debuted on the crew One mission hence why you guys had the um honor of naming it in the first place but this capsule was also used for the inspiration for mission that uh Jared also commanded um what is your take on uh this being one spacecraft but supporting multiple missions I think it's fantastic it just shows the flexibility of the design that SpaceX made when uh when looking at the crew Dragon Vehicles so I I I think it's very exciting to see a vehicle that can that can go from one mission to the other and and quite frankly do it quite uh quickly as well I think I don't remember the exact timing uh from our mission and when we landed to win inspiration 4 launch but it wasn't a very long time and yet you were able to take that docking adapter off put the uh KOA on in a in a very short time which is also pretty impressive have that noted here uh crew one took off in November of 2020 and inspiration 4 lifted off in September of 2021 that's that's yeah we landed in May of 21 and So within that short period of time you reconfigured the vehicle and uh and we're able to put that Koop on and launch yeah very impressive your mission patch sticker is in the is in the capsule that they're in now and oh add their own sticker to as well right all right well as you can imagine dragon has gone some changes for this and with changes comes extensive testing for the mission and all the modifications that we made in preparation for today had to go through kind of their own test regimen yeah testing is a critical part of qualifying a spacecraft like Dragon for flight rigorous testing helps identify and mitigate potential risks verify system and component reliability and helps ensure that the designs meet the mission requirements there are many types of tests a spacecraft might undergo when qualifying for including structural thermal vacuum radiation software and Integrated Systems testing one of the tests the new Skywalker Hardware underwent is thermal vacuum testing this actually tested how Skywalker withstands the extreme temperature swings that it's going to see while it's in the vacuum of space and while Dragon was being put through all of its Paces the Polaris Dawn crew was going through the same SpaceX training uh as part of our that we give to NASA astronauts they also had a train to perform their Eva though for basic training at SpaceX Hawthorne they train on everything from orbital mechanics to just how to live and work in microgravity also ran through numerous simulations of what the full mission would look like while they were seated inside of our Dragon trainer in addition to uring that they're familiar with spacex's Falcon 9 rocket and dragon spacecraft the crew went through an extensive training regimen to build their physical endurance and mental toughness ensuring that they are well-rounded and prepared for space flight and today's Eva now Switching gears one of the coolest things designed in-house by SpaceX the Eva suit is all the functions of our original space suit with the added bonus of allowing astronauts to exit the spacecraft while in orbit and this Mission this Mission gives us a great opportunity to test our Eva suits in space building a base on the moon and a city on Mars will require thousands of space suits so the development of this suit and the Eva performed on this Mission will be important steps toward a scalable design for space suits on future long duration missions as we mentioned SpaceX designs and manufactures our own suits and we have a little behind the scenes look for you something most people don't get to see the inside of our very own suit l e e e e introduce this new single pain visor helmet to the world of space suits the Eva suit visor is made of polycarbonate and is coated with copper and I or indium T oxide these two Coatings together reflect the Sun away from the crew as well as reflecting infrared heat back to the crew when they are facing deep space our suit has a HUD or heads up display which is a small display screen in the helmet which is transparent which allows the crew to see through the display to have unfettered access during their Eva but it also provides critical Telemetry to the crew so pressure temperature relative humidity we're trying to improve the technology and streamline it in one way and at the same time we're also trying to get it more and more manufacturable with each generation the ultimate goal is that you can put on a space suit and go out and get work done anywhere in the solar system um and not feel like you're wearing anything more than you normally wear every [Applause] [Music] day we also had a chance to talk to the SpaceX team that developed some of the hardware and procedures for our first Space Walk let's hear what they had to say Eva stands for extra vehicular activity and it's any sort of operation in space where a human is getting out of the spacecraft so in the case of Polaris Dawn we're going to be testing the mobility of the suit we're going to see if the in space operation matches the training we've done here in Hawthorne there's really a lot of different things that can happen during an Eva and this is the first step for Dragon and SpaceX when I first started working at SpaceX I never thought I'd be training a crew to do an Eva it's brand new it's so unique we've never done anything like this before and so we wanted to make sure we had the best possible training program for this Mission we want to see if we can train a space walk on earth in a way that's represented of what it feels like in space even though only two people are going to be going outside during this first Eva all four crew will be in Eva suits going down to vacuum Dragon was always designed to vent to full vacuum but we've never taken full Dragon capsule down to vacuum and this will be the first time we do it in space we actually put crew into a chamber at Johnson Space Center in Houston and had them live the exact profile that they will experience and making sure that no one actually experienced uh decompression sickness we have a couple new training assets for player ston to train the Eva specifically the suspension system that we have is situated on top of the platform of our capsule simulator the lines drop through the hatch they attach to a single crew member inside the capsule we can lift them up and get them situated so that they can ESS the capsule and perform their tasks at Skywalker the mobility Aid the Skywalker what's amazing to me is a lot of people are going to think it's a metallic structure just bolted to the top of dragon but a lot of development effort testing went into the Skywalker so we actually used similar technology as we have in the super Draco chamber to apply a thermal barrier coating to the outside of the Skywalker that is going to be a really really amazing Mobility Aid on the front end of dragon we also developed a sideways simulator so we flip the hatch on its side in the event the hatch fails to close they can manually close the hatch we had them do that in a sideway suspension system so gry isn't helping them close or helping them open that hatch mechanism it's new development for Dragon it's new development for SpaceX and the industry as a whole so this is a great example of where polaron is forcing the team to innovate in a way that adds safety and reliability to every dragon mission going forward that's this huge challenge for us to go solve but that's also an opportunity for us to solve the problems that we have to go figure out anyway for our larger goals like putting people on Mars the poison objectives are the first step towards that ultimate flight with with humans inside of Starship which is right along the SpaceX development path that that we have towards getting to the moon and Mars love seeing how not only the suit but the space operations for the Eva itself uh came together and were developed uh now we are still counting down to the spacewalk this morning uh the crew is or excuse me the crew on board is completing final fit-ups and we're going to be standing by for seat rotation and suit leak checks so we're continuing to truck along to the the the main event uh now Mike you obviously went through some of the suitup process that we saw in that package in terms of um the the development of the suit and how it's custom fitted for each individual and that's that's the same case for an Eva suit so maybe you can share with us what that experience was like yeah it it's extremely important uh to to have a suit that fits whether again it's the Iva the EV Eva suit or the Emu that we wear with NASA when we go out on the spacewalks and the reason for that is because uh if it doesn't fit right it can be extremely uncomfortable you can get what you call hot spots or uh there can be a a a place where the a crease when it gets pressurized can really put a a uh a hard point on your arm or something of that nature so having a good suit fit check is extremely important and and it's one of the things that was kind of fun as well because you get to spend a lot of time with the the suit team here with Chris and Eric and Mar oh they're fantastic and and I mean just over the years they've gained so much experience and they can really help you hone in on what a the really good fitting suit is is like with just the way they ask the questions and lead you through that that process wow what are what are kind of The Sensational differences from being in like the Iva suit because a lot of times the Iva suit when it gets pressurized you know it fills up but you're still in like a pressured environment with Eva suit you're in the vacuum right and so like what's kind of like yeah so you know that Iva suit it has a different purpose right and that the purpose of that Iva suit is to Keep Us Alive in the event of some type of an emergency that might happen during a launch or a landing and and so that's that case where either you have a fire or you have a depress event and so that suit's going to pressurize and so in that case we're not as worried about like the mobility of of the suits you just want to get home and and do it in a safe way and so you need to have enough Mobility to still be able to control the spacecraft and and do the things you need to do but but you're just not as worried about it because you're not trying to perform a maintenance activity or or something like that when you're going down on the on a on a space walk and and so I think that's that's one of the the biggest differences between the Iva suit and the Eva suit is just what the purpose of it is and what you're trying to do with it yeah that feedback loop um is so important to be able to communicate what feels good what doesn't um because I imagine uh you know as you're out there and having to perform you know as you mentioned maintenance activities among other things that the functionality of your body is critical to to to perform those it it really is and probably one of the hardest I think parts of the suit to design is the gloves right because absolutely you you hear us use the term it fits like a glove right we use that a lot but but you don't realize how much you use your hands when you're outside on a spacewalk as opposed to say your feet when you're you know cuz in space we don't use our feet our legs as much as we do our hands and and so when you're in a a pressurized suit like that and you're constantly grabbing and reaching you are overcoming the pressure of the suit and your hands can get just exhausted and you can get those hotpots um I had some issues with my emu gloves when I first started training at Nasa and I would actually get uh what's called delamination on my fingernails yeah and and so there's just little things like that that it really matters how well that suit fits and and how well it functions and and so uh it you don't realize how important that is sometimes yeah um now we are going to be stepping into suit leak checks soon um can you share with us a little bit about what that process uh entails um and and and more importantly because you you've actually experienced what it feels like to go through suit Le checks what what that experience is like extremely important part of the whole process right because before you take the cabin in this case all the way down to vacuum you want to make sure that your suit is maintaining the pressure that it needs to and and so it's a it it's a not a very long process it's usually just you know a few minutes to two or three minutes um and you know the the interesting part is if you don't pass that lead check what do you do next and and so there's always usually procedures associated with that as well that start checking your zipper start checking how you've closed things up did you not get something sealed quite right um and and so it's always a good point in the mission when uh whether it's on the Launchpad getting ready whether it's in the airlock getting ready to go out the door when you when you hear that yeah good leak check uh because now you know that you're ready to go so today's going to be kind of unique because all four of our crew members are going to be like doing The Space Walk they're all going to be exposed to the vacuum of space but I mean even when you did space walks it's never a solo act right like you're always out there with a partner you are it's uh it's extremely important in fact one of the hardest parts about our training for space walks is what we call incapacitated crew and so you need to always be able to get your crew mate back into the airlock if something should happen if uh if they should no longer be conscious and and something of that nature and so we we actually do spend quite a bit of time and that's why it's extremely important for us to go out in pairs because things can go wrong um and and so want to be prepared for those those moments yeah uh that's a great Point Dan to make that um while only Jared and Sarah are going to be somewhat exiting the spacecraft um all four crew members are going to be exposed to the vacuum of space and it's actually going to set a new record for most number of people exposed to uh or not them without a suit but like yeah in the vacuum of gravity all at the same time yeah that's actually interesting I never I never actually thought of that piece of this Mission and the fact that you're going to have four people on a spacewalk I I know at one point on a shuttle mission we had three y three folks outside on a on a space walk um and so yeah that's a that's a big deal and and kind of exciting you know one of the one of the things we do on the on the space station of course is We Have astronauts that are still inside and if we do get into those emergency situations they're there prepared to help us uh get back into the airlock and and uh and get unsuited and and things of that nature so of course when you have all the crew it just makes you think about those emergency situations probably in a little bit different way than we than we do on station yeah and hey if you're just tuning in we are still waiting to really kick off our space walk today so right now the crew is inside the spacecraft they're getting suited up we should be hearing some coms from them pretty soon and then X Dragon um ev1 is completing GL zipper closures but at this time we are ready for seat rotation copy that for seat rotation can you confirm crew is ready with the current glov zip DRS all right I I guess they just needed me to to say it was coming soon and then and then there it is uh but uh we are GNA hear the seat rotation coming up soon again they're in the reclimb position and I'll do stand by get the midd seat copy standing by so they're going to get those seats rotated and then we're then we're pretty much going to be ready to start getting into things and uh our Eva is going to officially start when we start flowing O2 into those suits um and so that'll kind of start our clock we're going to be showing you some of the Telemetry so all those numbers the bottom of your screen you've got a couple right now that won all the way in the bottom left corner that's your dragon that's your dragon cabin pressure that's in PSI ready for seat loation SpaceX copies initiating seat rotation great news there that's going to help give the crew a little bit more room to move around uh during The Space Walk and after we get through the seat rotation we'll be able to perform those suit leak checks that we were just talking about yeah before they do that they'll do what's called a tear so it's kind of like if you're ever using a scale you zero out the scale before you put something on it it's essentially what we're doing with the suits they'll get like a baseline reading and then as we start to actually pressurize the suits we'll be able to measure that against the Baseline make sure everybody's got basically a nice seal before we start that vent yeah that one's pretty important that was pretty important yeah um so a lot of that's coming up again some of the data on your screen you got cabin pressure you've got suit pressure Dragon SpaceX seat rotation complete and nominal all right seat rotations complete so now they're going to start doing that tear getting [Music] ready Cy and can I get a confirmation of completion per the call out in 2 decimal 18 [Music] complete with 2 copy at this time you are go to step into section three and teror suit [Music] deers now just a quick reminder in case if you miss the top of um the show we're we're going to be referring to the crew a little differently for the Eva activity um than we were previously so we heard Anna uh talk ev1 that was referring to Jared so his basically his call sign for this uh spacewalk operation is ev1 um Sarah's call sign will be ev2 Anna will be support two and uh Scott will be support one uh also Scott and Sarah are switching seats uh I perhaps they already have Cy stand by for HUD power for pressure sensor checkouts okay so our suit tear completed so next up is going to be the HUD checkout so the HUD your heads up like real quick we do have on your screen though that's your seed order so uh you've got ev1 Jared uh is in that seat he's going to be in that seat right now but once we actually get ready to open the hatch and everything he's going to be positioned kind of over by the hatch and then Sarah ev2 is going to be in one of those Center seats then you'll have Anna and kid on either side Dragon SpaceX suit Huds powered report results of primary sensor HUD checks in three decimal 2 so again that's our that's our SE layout we just heard the Huds are powered on so they've got heads up displays actually being kind of projected on their visor in their helmet which if you if you've ever seen space suits that's always kind of felt like that's that Space Age Technology that we're missing cuz Mike you guys you use kind of a a a simpler but a little unorthodox way to see like your suit data yeah that that's right Dan it's uh of course the the suits and they that checkout complete anomal copy swapping the backup sensors standby to repeat H checks so of course the suits that we use for the the space walks on station are a little bit older they've been around for for quite a while and and so some of this uh technology uh you know look it's our first live views inside Dragon resilience for this morning that's fantastic yeah I think this is the definition of chill vill yeah so there out of his seat that's Commander Jared uh who like I mentioned before will be referred to as ev1 behind him we can see already in his new seat uh pilot Scott kid potit uh he will be support one and then moving around in front of us is Sarah who will be ev2 and then just out of view underneath the camera but I think you can see her visor is um and a men who is support to Dragon SpaceX we're on backup sensors repeat Hut checks the crew is going to check out those heads up displays one more time real quick that check out on back at C copy good Huds returning to primary standby for helmet camera checkouts on that heads up display they'll be able to see the O2 Flo timer that's kind of like our mission clock essentially like once the O2 has started to flow to their seats and they know they've got about an hour and 50 minutes just under two hours for the whole time uh they'll be able to see their suit pressure temperature basically a way to kind of keep an eye on things and we were talking about it a little bit Mike but on the Emu is a little bit different yeah the Emu is certainly different uh a lot of that kind of information is on a on a display right in front of you that you have to kind of look down to see and it it can be pretty challenging to see in fact a lot of the information you have to use a mirror on your wrist uh to be able to to read it and know what you're what you're controlling as well uh you mentioned the timer of course we don't have that kind of information on on ours and I'm not sure I'd want to know that because I'd feel the pressure of I got to get a lot of things done I'm running out of time yeah all right um so they're they're going through these HUD checkouts again pretty soon Dragon Space X powering on helmet cams we're going to get the helmet cams powered on again give you that kind of look right over their shoulders yeah pretty excited for these we've uh seen them utiliz during the training uh sessions that the crew has undergone and we're so excited to to see them live today yeah I I tell you the helmet cameras I mean it's going to be fantastic views right that we're all going to love but but there's also a very important um role for those cameras as well like when we have the same thing we have helmet cameras with the emus and what it allows is your ground team Dragon facex suit cameras powered confirm good health so it really allows your ground teams to to kind of be able to see what you're doing and video and almost double check your work copy checkouts complete Huds will remain powered proceed to step three decimal three operations review through three decimal 8 report one complete all right so we got through HUD checks we got cameras on powered ready to go so right now the crew is going to go through they're going to do kind of a final review of all of their procedures like you talked about this a little bit like these things are so choreographed because even if you couldn't see the clock like you're on the clock so you've got to you've really got to make the most out of like every single second you're doing one of these do and and of course you see that with with today's space walk as well space X repeating checkouts are complete Huds are going to remain powered proceed to step 3 decimal 3 operations review through 3 decimal 8 and Report when complete Cy and and the reason it's so choreographed and important is because you only have so much time outside right you only have so many consumables that allow you to go out there and so you want to take advantage of all of that you want to have every step very well scripted so that so that there's not a lot of wasted time now that being said it is nice when you're out there once in a while to just kind of take a moment look around enjoy the views kind of try to absorb where you actually are which uh can be a pretty incredible as well every every once in a while guys I'm a little tired I'm gonna take a minute that's right I need to take I see my house from here that's right yeah all right but like it's it's awesome we're seeing the crew inside we're getting close to the start of today spacewalk we're going to start flowing O2 to the suits and that's when our clock's going to start right now they're just doing kind of final cabin configurations they're going to check the lighting uh they're going to make sure that their umbilicals are in the right spot that's one of the things you'll see that's actually one of the the the roles that our support uh crew members are really going to that's kind of one of their one of their primary jobs during the spacewalk is to manage those umbilicals for you guys Mike you had one that's uh what plugs into kind of the leg in your suit and that's what's providing like the breathing gas coms connections all of that stuff uh for this spacewalk today it's a little bit different this one uh that uh they're going to be using has some tethers in it um for Anna or for Sarah and um Jared it's about 12 feet long so it's like about double double the length the way you guys so so it's Dual Purpose right it's it's providing them the the air and the cooling that they need while they're out on the spacewalk uh but it's also providing that safety piece right so that if uh if something should happen they should slip or um that that they're not going to go floating off in the space with the Emu uh that we use on the space station we actually you know all of those consumables are a part of the suit itself and we have a separate safety tether that the first thing we do when we open that hatch and we go out is as we hook up that safety tether and it's an 85 ft reel that uh as you're moving around it it goes out with you to again protect for that crazy moment when maybe uh an emergency happens and you come off station how how hard was it to manage all of those tethers I feel like every time I watch it was like there's no way in heck that this thing isn't getting snacked on something no you're absolutely right because everything and and you talked earlier about making sure there was no loose items in the cockpit right because when you open that that hatch uh things are going to want to float away if they're not tied down or stored or anything like that so when we go out on a spacewalk not only do we keep us Tethered to the spacecraft but any tool any part that we take out with us also has to be tethered and it can be quite a challenge to manage all you'll open up a bag and there's there's 10 pieces of Hardware in there with 10 different tethers and they get all tangled up and and it can really be pretty challenging it's important though um we simplified that a little bit for this Mission um we actually basically built in that tether into the umbilical one of which you can see actually they floating uh under Jared's right arm so not only does that Pro provide airf flow and comms and uh all the normal connections that we have in the in the umbilicals but we also added that that strength uh to provide that protection yeah and and the managing of that tether is extremely important because you know as they go out if it can get tangled up and you actually see Sarah there kind of moving around right it's it's very easy in in this environment where you're floating BX Dragon Eva offer you complete who are in position to Eva nice EXC Cent position but you saw Sarah kind of moved the tether out of the way and the part of that is that's actually impacting you go to command VX push a talk all seats C and so this will this will be one of the unique things about the spacewalk today it'll it'll feel familiar if you've ever if you watched some of Mike space walks uh the crew is going to go over to what's called V is set go for com check ev1 com Che ev2 com check support one Contra support two com check SpaceX copies all good coms all four crew cop [Music] so essentially now all of our crew are on open mics they can all talk and hear each other and they can talk to the ground and so you're going to hear a lot more chatter start to pick up uh once we start the suit pressurization you're going to hear almost like a sound that's just the air starting to flow into their suits um how how loud does it get inside your suit it it actually is quite loud uh that air flow is just constantly which is a good thing right because not only is it providing you the oxygen but it's also helping get rid of that CO2 that you're breathing out so you want that air flow uh to be constantly going and and so you always are hearing that van uh that that's uh making that happen and so that is that is certainly pretty important and the Vox thing I got to say you know it's nice that you don't have to push a button when you're outside there to to talk Dragon SpaceX for about 90 seconds from E initiation got some fist bumps going on yeah and we just heard we're about 90 seconds from Eva initiation so we should see them get the go to close their visors and then they're going to open up one of the O2 valves on their suits to start the suit Purge and that's going to be the official start of our space walk today so we're we'll get through the the final goes and then we'll see those visor get closed oxygen start flowing and we'll be off I love how everyone looks so calm and collected right now I think that's a a a great visualization of just all the extensive training that they've gone through to get to this point this has been years in the making um I'm sure they're excited uh but everyone's focused it it is an interesting time right now right because one of the hardest parts I always found the Bel Dragon SpaceX SpaceX is go for Space Walk operations report visor down ready for secondary O2 FL initiation and crew is go for Space [Music] Walk verify your visors are [Laughter] [Music] closed secondary 82 is open [Music] and that you are go for the EVS ev1 is go ev2 is go support one is go support two is go [Music] Dragon Space X initiating secondary [Music] O2 and with that news our Eva has begun so you're you're going to hear referred to as primary and secondary O2 primary is going to be that primary flow of oxygen to pressurize secondary is largely putting oxygen into their suits to help with cooling but secondary is the first one we turn on and so our O2 flow timer has started the Eva start at 312 a Pacific I'll do the math on UTC in a little bit so this first this first operation or this first step in the operation is a suit Purge so inside their suit obviously when the visor is still open it's still a nitrox environment it's the same is the cabin uh and since they're going to be at a lower pressure than what you can basically live at with with oxygen levels um they're going to be on pure O2 they're going to be a 100% oxygen environment and I mean you guys were kind of in the same thing and it's it's because like your suit can't you can't move a suit around at 14.7 PSI can you maybe you can like no that would be pretty that'd be pretty tough to do and and as we talked about earlier that's why that Mobility is so important because uh when that suit is pressurized like that it it can be challenging to move around absolutely so here on your screen we can see the poist on crew now with their visors down the Eva has begun we are beginning to flow that uh O2 through now we will of course bring these views to you as we have them but due to ground station coverage they do come in and out here and there um but every moment that we can we will certainly be sharing these with you um I also wanted to point out quickly that the the the window near kids feet was so much brighter than it was uh just even 5 minutes ago we're going to be seeing that uh in STK contrast as soon as we get uh the Eva or with the hatch open and ev1 out there yeah it's kind of interesting you you you mention that because as you're going around the earth as fast as you are right in in 30 minutes or 45 minutes or so you can be passing in and out of that sun and and going into Shadow and and so that brings its challenges as as well because the temperature um can change pretty drastically just in those transitions from night to to Daylight and and so there's a there's a it's an interesting moment when you're passing through uh through that time that's actually one of uh the reasons that the visors have this new cating on them different than when you wore the a similar helmet um that coating actually helps to insulate the individual inside the suit so when they're looking at the sun dragon Space X a reminder after the initi of primary O2 flow ev1 ev2 will need to adjust Vox threshold low following primary O2 flow [Music] initiation ab1 copies D2 copies Dragon SpaceX secondary flow Purge complete close secondary O2 Valves and Report ready for suit pressurization ev1 closed ev2 closed report one closed support two closed BX dragon is ready for seep pressurization initiating primary [Music] O2 this is normal this is with the air flow coming through uh the crew members on Vox meaning uh that their their microphone is on the whole time so Sarah and Jared are going to be adjusting their audio levels um as this flow continues to to help regulate that yeah the the the voxel kind of attenuates so it'll it'll sound like this now but as we get through The Space Walk it'll kind of come down and you'll just hear voices a little bit more clearly uh their their voices are actually going to change too like did that did that happen to you did that throw you Mike the first time you heard that absolutely did yeah cuz you're you're you're talking and you're going who is that right yeah you don't realize how how much different it can sound um your voice can sound in that lower pressure environment yeah speaking of lower pressure we can uh we can see the pressure changing there with the Telemetry in the bottom left hand side of the screen so we can see that suit pressure going up um and we're able to keep tabs there um as well with the dragon pressure so Dragon uh on the far left Circle that's the pressure within the cabin and then suit obviously that's the pressure within the suits so we'll be actually be able to and I think we've kind of been able to see it already um that these suits will inflate a little bit um look a little different and we were talking about the the visors before so when they're in the sunlight that coating will help keep them cool and not overheat them and then when they're in Shadow it'll help keep them warm so uh and it's also like your sunglasses as well right serves that purpose all right so at this moment the suits are getting their primary pressurization this takes about 3 and 1 half minutes a little bit less and then we're going to go through those actual suit leak checks I the crew will probably get a reminder they have to stay really still when we do those leak checks and I always was kind of wondering like why the heck and like if you if you bend your arms you're actually going to start you know changing the volume inside the suit that'll cause pressure spikes and so that's right got to stay really still yep and then after after we get through the Le checks we're going to go through kind of that final pre-breathe uh where they're going to hang out in that 100% O2 environment just to continue purging all of that excess nitrogen um pressure stable perge complete halfway secondary go on report one complete ev1 open oh open the sh open and right there they they finished the purge and they did a quick uh reinitiation of that secondary flow check resp second FL complete give you one cl your you [Music] one St you confirm [Music] second these handles that we see Jared holding on to these were one of the additions uh or uh customizations for this mission that we talked about [Music] earlier support one facex cont [Music] [Music] we got you all right copy got the [Music] Dragon Space X beginning S Check evaluation and then still [Music] check so once again that background noise is expected um that is the microphones and the flow of air uh within the suits so we're trying to stay quiet to uh along with you listen in on what the crew coms uh are as they go through um we're also uh going to get views in and out as we mentioned before due to uh ground station coverage and it is it is a little bit tough to hear we just heard though that we got four good leak checks on their suits and now they're going to be in this final suited pre-bath and so again this is going to last about 19 or so minutes uh and this is just to do kind of that final get all of the excess nitrogen out um and we started pre-b just two two hours after they got on orbit just like you know gradually lowering the pressure and I mean free B that that's something that kind of evolved over time with the space station where where were we when you were doing your space walk yeah so we were past the kind of the camp out phase of free breathe um but that's how we used to do it and it's very similar to what what the polaron crew has been doing over the last couple of days we'd actually have uh astronauts stay inside the crew lock overnight at a lower pressure just like they did when they first got on orbit now we've moved on to we do it the day of it still is a long long day we start about 6 hours prior to going out the door uh but it's not 2 days prior it's worth noting uh along the lines of training and how the crew prepared for this mission that all four of our polaron crew members uh and some additional Polaris and SpaceX crew members actually went into um a a vacuum chamber and tested these suits out and spent uh a bit of time at lower pressure just to help learn what that feels like and get used to it well and I think the other thing that's important about that is it's real right it's it's the first time that you're in that suit and it's actually a vacuum around you right and there's just something mentally that I think is important to put people through those moments before you actually have to experience the first time in space yep we we saw some of the unique ways we train the crew for this and I mean training for space station space walks I'm still really upset I never got on the pool uh looks like one of the coolest like parts of being an astronaut is like not being in space but just doing some of this training yeah Dan I I I tell you I can still remember the first time I stuck my head underwater not in the in the soup but in the for diving but you can hear the Cals of of everything that's going on through the water like that and it just gives me goosebumps to think about think about that it was a really neat environment but it looks like these guys had a pretty neat way to train as well with the uh the the harness that would hoist them up and out and and all of that that's that's pretty impressive yeah um we definitely created some rigorous uh new training for the best we could simulate an Eva while still on Earth um with hoists and uh you know it was um it was a lot of fun to watch them train be back on board with cameras in three [Applause] minute so our just called up we'll get we'll get views back on board in about 3 minutes as Kate talked about earlier we're using ground stations for our video coverage all of our communication with the astronauts are through tedris so tracking a data relay satellites so we have a littleit we'll have constant audio but that video we need those ground stations uh but right now they're just they're in that pre-breathe uh that final pre-breathe still we started our spacewalk about 13 minutes ago when we initiated O2 flow to the suits the time was 3:12 a.m. Pacific 12 1012 UTC I did some quick map took me took me 13 minutes to do it but I did it um so we're once they're through this pre-breathe we're going to start getting into to some really exciting parts of the Space Walk and and then after after we get to the pre-breathe we're going to get to cabin vent so you know let's let's go through your head when you're like man it's happening the A's going out it's really happening it's happening yeah I I I tell you it is a long process to get to this point right they've been prepping for this for two days right and and one of the hardest things I found about the space walks is the waiting hurry up and wait hurry up wait right you are so ready to to go out and to do this Mission and and to go out that hatch and it just takes time and I think that's one of the things you talked about my fifth versus my first you're fifth you kind of understand how long it's going to take you have a better appreciation for how long it's going to take and so you literally find yourself in these moments when when you're kind of waiting through this pre-breathe or you're waiting for the airlock to depressurize just kind of find yourself just floating there kind of zon out trying to keep yourself calm and relaxed and until that moment when it's it's game it's game time yeah now just a quick mention we about a minute out until we uh get those views back uh inside the cabin um The View that we had previously was our Dragon tracker which uh if you want to see where Dragon is you can actually look that up as well um we have it on our website spacex.com slf follow- Dragon um but yeah just as a reminder uh our our crew they are in their designated or well Jared's not but um the yeah um our our crew members basically Sarah and kid have switched their seats for the Eva um we saw we last time we were able to see inside the cabin we saw Jared awaiting um to open the hatch so he wasn't in his Commander seat but uh Sarah is now sitting in Scott's pilot seat also known as seat 3 um and then Anna is on the far left side and Scott is on the oh yeah we can see it there on the far on the far right side um and also just a reminder uh their their call signs for these Eva operations um Anna being support to kid being support one and then Sarah being ev2 and Jared ev1 representing uh that Jared will exit first uh do his activities which include just some Mobility testing of the suit uh and then Sarah will go out and perform the exact same uh testing once Jared comes in um meanwhile uh kid and Anna will function as the eyes and ears uh they will be performing uh their own uh list of operations during uh or their own list of tasks during the Eva so while Sarah and Jared are going to be the ones that are you know partially egressing the capsule once that uh forward uh door is open uh kid and uh Anna will also be performing in Eva in their own right that's right and we talked about it earlier first time four people exposed to the vacuum of space like that's there's a lot of first in this that's going to be a really cool first not just for us and dragon um but we are going to be getting views back really soon we're again just in that final pre-breathe step right now and then we're going to start venting uh venting Dragon down to near vacuum so we're going to have couple of different valves that are going to open up and the atmosphere inside dragon is going to start going overboard out into into the vacuum of space now the crew the ground they can control they can pause that cabin venting if they need to uh we can pause and resume the most likely reason is for ear Equalization is again you're you're going through a lot of pressure changes anytime you do a space walk and so if you've ever flown on an airplane and your ears popped you've experienced just a little bit of what they might be going through right now uh once we start cab venting uh if we terminate or abort that The Space Walk during that venting we can not start again we talked a little bit earlier about how consumables are like the thing that really drives you uh and for us we don't have a great big air lock with this with you know a full station worth of oxygen and stuff like that um so confirming at [Applause] [Music] 3 T1 go and copy initiating C venting here we go that is great news so uh that breathing of incre that pre-breathe where they were breathing increased oxygen we just heard that uh they're good they all all four crew members gave the go uh so now we're going to vent the cabin yeah in in total this will [Applause] take in total this will take about eight8 minutes and you can this the graphics you see in your screen that's live Telemetry everybody so you can see the pressure inside Dragon starting to tick down you're going to see the soup pressure tick down as well is what we're really trying to maintain is a pressure differential and so with these suits we're going to be hovering right around five or so you might see about 4.9 to 5.1 5.2 um it'll be about 4.9 and then we'll probably see it go up a little bit uh when they reinitiate the secondary flowop at end and you talked about that about five PSIs what the suit will be we're actually a little bit lower in the Emu yeah and so we've talked a lot about Mobility that difference between we're at 4.2 and they're going to be at five it can actually make quite a bit of difference just in how hard it can be to move the suit around Etc yeah this crew got to and that's something we can simulate you know on in a vacuum chamber or even just uh in 14.7 you can you can simulate that that differential pressure getting C us from the crew they're they're monitoring along we're going to hear that kind of we're going to hear that chorus pretty frequently where you do those kind of frequent most like check-ins and I know you guys did something kind of similar where like you'd have to pause and you know check your gloves that kind of stuff we we did I I will tell you one of the interesting things watching this uh live right now the difference is how quickly the depressurization is happening here is uh what my experience was and and so you talked about being able to clear your ears and all that you're not giving a lot of time for your you're not giv a lot of time for your your ears to adapt to that lower pressure so this this is seems pretty quick to me yeah break breaking new ground with this new suits new operations for everything think we're at about 4.5 we're going to see that tick down it's going to get down to just under one and it's not going to go all the way down um and then what we'll actually see is we've got a capability to open the hatch automatically we got a motor in it um but Jared's actually going to unlatch it and he's going to give it a little tug to kind of break the seal break any of the kind of the stion in the hatch itself and that's going to kind of take the capsule down to its final event before Sarah who's at the displays she's going to command the hatch to actually open um yeah that's a good point and you know there's there will be slightly more pressure inside the capsule so really just helping four PSI two pressures look good copy four so Jared really can't open the hatch all in one fluid motion so we will see him uh release that that pressure slightly um before being able to open it completely and I think one of the important things you guys I think had talked earlier about you put some more um restraint devices inside the capsule from when I flew on it and that's extremely important because there's going to be some force that Jared's going to have to be pulling down on and he needs to be able to Anchor his feet somehow um otherwise he's going to pull and it's not going to go anywhere and so the the new restraint devices in there we're going to see how important that's going to become here when he tries to open that hatch yeah yeah that's that's one of the things that's why we have Skywalker out there we've we've talked about how kind of similar to to Gemini when they were first kind of stressing their legs but important to remember we've got that 50 or 60 years of space flight history that we're able to draw these are new suits this is a new operation this is to you know work out all the Kinks and really test this for the first time but we're going into this with a whole lot more information than they had back then we no you need handrails or it's going to get real hard real quick that's right that's right yep uh we did we did also hear uh dragon's moving into its uh its Eva orientation essentially we're going to point the trunk at the sun under 3 PSI I think it's also interesting you notice that the Deep pressurization has slowed down a little bit right so as we get to this lower pressure it's it's just taking it long for that remaining little bit of air to to uh go out through the vents an E1 come Che you want mad and mad and well also hear the Box starting to adjust its levels that that flow of oxygen has not stopped but the microphone's kind of adjusted and it's getting a little bit clear and yeah keep keep an ear out you might hear their voices start to like tender down a little bit B I do think that's a an important Point Dan that how important Comm is yeah right and and when it's compromised a little bit just by that extra air flow and the Vox not keeping up with it right away uh how challenging it was just to hear those calls and they can be some pretty important calls so uh Comm is is just critical we can see Dragon capsule now approaching close to two siia like Dan mentioned earlier that's going to get to just under one it's incredible to think that uh you know the Dragon capsule in all of its power and glory and awesomeness the the new capsule is around their bodies right that that is what is going to protect them um from the vacuum of space and uh you know just seeing how even even though it's puffed up and we know that it's uh you know holding that pressure it still looks so cool for lack of a better good good yeah you really have four Mini Spa or spaceships in there approaching 2 PSI guess that means we have four aliens in there too yeah that's right Dragon SpaceX plus than one PSI from hatch operating pressure we have a tedris Handover in 2 minutes we are going to wait until after the teacher hand over to command in Hatch open [Music] prep one copy yeah I think you heard that the the teed's hand over so there's going to be a a short period of time there where they're out of Comm and we're at it's kind of interesting because we're at a very critical phase ah as well and so you want to make sure you have all the data and uh and the ability to talk to the astronauts before you actually take that next critical step we'll see it we we're seeing that pressure continue to tick down Dragon originally designed to be able to still operate in a vacuum that was some of the emergency situations I know you train for Mike we did make some modifications to this one uh to essentially turn Dragon into a functional air lock um we added some additional uh vent paths um we do use like some of the same ones that you guys Ed to like pressurize the vestibule and stuff like that um that are actually in the hatch but we've got a we've got an extra one in there to to be able to essentially do that Dess as quickly as we did uh but we're going to we're going to see that get down to a little under one and then we're going to see Jared kind of jump into action he's going to unlatch the hatch and then he's going to give it a a little poll to break the initial stion and then we're going to be able to uh see Sarah Pia I'll fo One Cop now it's one thing to note that while we have been progressing through this pretty quickly we did have the capability to pause if any of the four crew members needed to uh you know take a moment to you know let their ears um come to equilibrium or just kind of get comfortable again um we did have that option but everything has been going really well so far we haven't had uh to to pause cabin venting and if you're just tuning in heck of a time to do it we're about timing a little under 28 minutes into the uh into the spacewalk today which again that started when we started flowing O2 to the suits of these crew members that was at 312 Pacific 1012 UTC we did heard that dragon's now in its Eva [Music] attitude so again we've got we've got dragon's trunk pointing towards the sun watching to the Cross [Music] View that was SpaceX core Arthur baralt just letting the crew know uh that we're the cameras are on and inside and uh basically which camera is is looking at them it's it's so fun to hear Arthur's voice because he was actually a part of our mission as well in fact Arthur was an intern started out as an intern when we were first uh starting the training and and so now to see him as a as a core and uh is pretty neat very similar to Sarah who also started as an intern yes yeah right we're coming up on one PSI you might see you saw the light change a little bit through that window is we're in our Eva position trunk facing the sun that's going to help us with thermal uh inside the capsule and on the cruise suits also going to make sure we're maintaining that uh that optimal pointing for communications with the tedris satellites uh once the hatch is open we're going to disable any of the Eco thrusters that point forward is you know want thrusters firing off when a crep memb outside we at one you can see the suit pressure is ticked down too there's about 4.7 difference between the suit uh and the ambient cabin there in dragon that umbilical that you see there uh just to the side of Jared that will continue to flow the air into his suit as well as provide Telemetry and Communications connection that's also where we have the um safety harness built in as well so it's able to Dragon SpaceX cab pressure below hatch operating limit standby for transition to hatch open prep here we go want M did you get to open the hatch I did did yes yeah when you when you go out as uh G hatch open Dragon SpaceX for hatch open prep confirm CR to open [Music] hatch that is great open you SpaceX copies Dragon you or go to open hatch go excited go to open the hatch Mike as you mentioned before that continuous communication hat handle [Music] as you can hear we do have a crowd Gathering outside of Mission Control uh here in Hawthorne in their excitement somebody dropped a cup we can see our commander Jared isaacman now turning the crank which allows the uh that top hatch to open we'll see him give it uh a pretty heavy uh1 hatches visually indicated open space copies stand [Music] by should see him give that hatch a pretty strong jolt to release that stion hatch is now unlatched Mike talked about you see him getting his feet getting his feet set that's right Dan You' ask if I got opene in the hatch so when you go out a zv1 just like Jared here is ev1 that's that's typically the role for for you is to open that hatch and the draw straws whatever it's exciting it is it's very exciting yeah now for those of you that have just recently joined as you can see we have successfully depressurized the Dragon capsule uh down to Zer psia you see that in the bottom left hand side bottom left corner of your screen um our four polaron crew members um have uh gone through the uh O2 flow and we see Commander Jared um isaacman now standing by uh to open that top hatch the nose cone is already open it opened just shortly after uh the crew got into orbit uh so Dragon SpaceX Target pressure [Music] reached Space X I'm on feing the hat now Jared now opening Dragon resilience into space so we saw some motion on the hatch again he's just giving it kind of that initial tug and then Sarah gets to push the button to swing that hatch [Music] open much more movement there on the forward hatch this must be pretty exciting for Jared because that center part of dragon Space X that's a good brace we're going to have you repeat the [Applause] [Music] operation center of the hatch actually has a window the hatch is unseated copy we give it another [Music] call hatch is several in cop we see it looking out that tiny window there in the forward hatch knowing he is going to have a much bigger window in just minutes Dragon Space X complete ev1 return to [Music] seat then ev1 copy transitioning back under the display so again one of the reasons we had jar do that was to Dragon SpaceX we're actually watching that hatch we're going to have you repeat the last operation sounds like they're going to have repeat them one of the reasons we're doing that is just to kind of vent any of that residual atmosphere and ev1 you are go for manual hatch [Music] open sounds like we got our first audible of the day as we said that we can open the hatch opening the hatch manually we could open the hatch man we could open the hatch automatically or we can do it manually and so they just gave Jared the go to open that hatch manually so we we just went out of ground station reach so we'll get the views back W we'll get the views back real shortly uh and then the the hatch get see hatch open and hopefully we see it yeah hope we see a hatch open hatch is open X copies hatch open that is fantastic news uh for those that1 I'm looking at for seals initial view looks pretty good don't see any VES or ination copy on Hatch report yeah that seal that you just heard him talking about it's such a important part for the end of the Eva rights so that when they close that hatch again you get a good get a good SE SpaceX can you command open forward hat we going to stall it open there is our first view of the forward hatch wide open to space forward hatch if you just jumped in we are 38 minutes into today's spacewalk and the hatch is open on Dragon first view from a helmet cam looking out Dragon SpaceX we see installed ev1 is go to [Music] continue that structure you see there is for [Music] E1 I'm transitioning back from under the display SpaceX copies we're with you in your helmet cam once again this helmet cam what we that structure we see is the the space walker this is Jared now egressing through the forward hatch of dragon resil I the first views of the first ever commercial spacewalk and at the bottom of the mobility is progressing I have a feeling the crowd is about to go wild there Fay back at home we all have a lot of work to do but from here bir sure looks like a perfect [Music] Road ni take you one I'm going to step in T Matrix One singlehanded Mobility demonstration Commander Jared isaacman now emerging Matrix one watching from the nose cone up down left and right are three [Applause] pitch and roller three your off two switching single-handed operation to a fine static and with Dynamic disturbance switching to left hand [Music] up down left and right are threes maybe a two ditch is a four roll is a two Y is the two so these are the suit Mobility checks that Jared is singed operations Dynamic and with disturbance are all adquate test Matrix one complete Hut Jack 5.3 dpsi 48% RH 33 de CSI SpaceX copies test Matrix one and HUD read [Music] out screw off Jack e one good good D stepping into vertical translation we're going to start with the horizontal bars [Music] [Music] all right we're going to transition over to vertical [Music] i' say vertical and horizontal are equally workable slightly favors horizontal I'm going to do a Max reach left hands at the top of the mobility a at the midpoint you have good video we just lost our live video stand by one okay Switching over to Max reach [Music] switching holding up Max any1 go ahead and continue the operation uh we'll let you know we're back on with live [Music] video Cy [Music] that for your awareness Max reach 28 and the mid bar that's test Matrix 2 is complete C read out 5.3 PSI 33 decimal 9 Celsius 50% RH copy test Matrix complete and hard read up check e1's good we're good stepping in the test Matrix three and demonstration ev1 Space X for Ingress [Music] time go Space X recommended Ingress time of 02 flow plus 4 7 [Music] Minutes copy that Ingress Time 4 S minutes and dragon we're back on live video from the [Music] nose happy night SP [Music] and space a ev1 I would say the handsfree demonstration is very comparable for the trainer in terms of the foot restraint space copies and ev1 when you have time if you'd like to return to the reach demonstration uh we'll take a look at that with the live video happy that test Matrix 3 is complete the Hut readout is 5.3 PSI 47% R 33 deal a c and stepping back into max reach copy test Matrix top of the mobility Aid and uh let's get a Quick Crew off check e want good good I'm good happy that okay uh Max reachs whether it's left or right hand seems to be about the same to the mobility Aid and then the mid R copy we see it checking up from the [Music] bottom and go back SpaceX negative we got about 1 minute until ev1 Ingress Happ to 1 [Music] minute it's [Music] gorgeous you want to see if guys to get the R right ev1 we're checking out your helmet cam [Music] now now I'm checking out your nose con right now and looks pretty good cop we're no see you looking at us all right we're coming up about that 02 F timer time two check for inra E1 good all right St ja TV1 for the huge steam effort that have took to get us to this point we know it's just the start and I'm transitioning back in the vehicle [Music] [Music] [Music] face at TV1 we taking a quick look here the hatfeld from what I can see so far they look pretty good copy on the hatch seels and standby for transition to read off [Music] reset face this and ev1 is clear [Music] [Music] all right so Jared back inside uh we we heard him going through What's called the test Matrix uh it's basically just a bunch of Maneuvers using different hands using the foot Mobility is in progress [Music] calling out numbers right now though we're doing you just heard cop Arthur call up three off resets so we didn't use any of the forward thrusters while Jared was out there we're re-enabling them putting us back in our perfect attitude before Sarah gets ready to go out the door fun thing to note it's still not a perfect vacuum inside a dragon is it's an open loop system so oxygen is kind of getting dumped into the cabin as this is going on so you got a higher pressure in Dragon than you have outside so we're not worried about thrust or pluming yeah now you mentioned Sarah um just like Jared she will have 10 to 15 minutes uh outside perform those same sets of Mobility tests as Jared uh like we heard the core do um with ev1 uh they will call out when there's one minute remaining uhx attitude reset complete ev2 go [Music] for there is Sarah's clear to copy crew check for Ev e ev1's good ev's good good two good Ed is going to go stand on the door and then step outside now this test Matrix that uh Jared just performed and the one that Sarah's about to perform they have both committed to memory um in order to execute these um we saw it being done pretty efficiently I can't believe how quickly that time went by Mike we were talking about how your Spice Box for hours and these guys only have 10 to 15 minutes and it just like that yeah it it can go pretty quick and uh but fortunately um feels what's good I see a little bit of a bulge between 14 and 13 so you're hearing Sarah call out some more of the seal check there as as she's exiting out three feed SpaceX copies that report good fix so this was something we knew might happen um and between 28 and 27 copy the crew trained on exactly what to do in this scenario just pop it back in and one final between 19 and 18 [Music] [Music] that might be best reated and hatch closer St T copies can you repeat the location complete between 19 and 18 all right copy I'll track that and uh ask again when you're in [Music] cppy eg2 is theing with e super exciting to see this our fellow space xer yeah Sarah Gillis now about to make her Space Walk e one I'm going to hand this back to you like we mentioned Sarah will be performing the same uh set of Mobility tests uh so we will do the same uh try to stand by and listen to those PS I mean I said it before a lot of the sare characters we want to do this all right stepping into test Matrix one this sanded Mobility really cool to see one of our own out there that's awesome and ev2 for awareness we're watching from the nose [Music] con and copy all I just say in all three translation access I'm having so my cross purp movement forward back aming the bit ever roll s it's left right and up down a bit of a PT but all are achievable St is three y the three four and PES the three [Music] w than for for next man stepping into vertical [Music] translation SpaceX copies and ev2 for awareness we're tracking an Ingress time at O2 flow 59 [Music] minutes copy 59 minutes horizontal bars are definitely preferred and I'm not be able to fatalize my body with single hand disturbances us left and right stepping into MK reach do you have visual a firm we have visual on the nose [Music] cone copy from bar four to Bar two from top down and similar reach from bar two up to Bar four SpaceX copies reach and6 1ce SE pressure 5.25 33.8 Celsius 37% humidity SpaceX copies HUD read out and test Matrix one complete 762 like we mentioned before views going in and out doing during excuse me due to those ground station uh coverage gaps yeah we we coms some of the same coms are through satellites but we've got ground stations for video on dragon as you can see in the tracker we just flew over on New Zealand we're about to go right over the middle of the Pacific no ground stations in the middle of the Pacific are actually pretty good we're hearing the voice of mission specialist Sarah Gillis our fellow space xer on her Space Walk got she got about a minute left and then she's going to start head heading inside and see with a little more work I can actually get between almost bar one and bar four on that stre space has copies and you could see the Earth dark and we flew into like an orbital and test Matrix to trying to combine them so we'll call that con he pressure 5.27 38% humidity 33 7 cius Space X copies Matrix complete and H out s in to handre demo I'm able to engage and disengage my feet copy to and once you are able to engage disengage we'll actually have you start Ingress we're just over 5 9 Minutes O2 flow poy that check for Indo good 14 chy coming on in all right and just like that Sarah's going to start making her way in C check those hatch seals again SpaceX copies on Striker plates and ev2 I have one more ask for the hatch if you can uh check out it as well when ready to copy ready copy copy and ev2 what I'll have you do is when you Ingress can you get eyes on the hatch handle mechanism and see if the handle has been stowed in the Do Not Stow uh window and report if you can see that Che I think it's just outside copy just outside thank you just outside the range and for awareness I do see a couple of those same points folding again between 12 and 13 copy your go no mostly between 12 and 13 right now SpaceX copies at 12 uh if you can you're go to address those copy and these numbers being called out represent the location around yeah the location around the circular hatch just identifying where these bulges are so Sarah is now reing that seal not quite able to reach the bathroom so we'll proceed with clearing for hatch closure just like that we're already hearing about hatch closure it's incredible that these two Evas just in two blinks of the eyes are uh isar on your screen there is SpaceX core uh or crew operations and resource engineer on duty tonight is Arthur baralt this is the uh the voice to the crew throughout uh their operations of course you know everyone has to sleep so we have different shifts for core um but Mike your time and Dragon driving close you're good Cy depl handle a f and for I'm closing once we get ground station coverage uh again we will be sure to bring you views within the Dragon capsule but right now Sarah is closing the forward hatch it sounds like we might give the motor a try confirmed the hatch is visually indicating close hatch is verified last hey commanding EV hat closed Eva hatch closed all Dr goes enabled [Music] Dragon SpaceX we see Eva hatch closed and pressure indicates good hatch seal standby for transition to Eva repress one and E1 copy everyone check secondary O2 valve Clos c supp one I'm good d1's close2 close one [Applause] close there a couple of real big moments right there Sarah was able to make surey second FL is closed and agree eess she was able to make sure that the seals were in good spot we got the hatch closed you can see a half PSI for 8.3 see the pressure starting to take up just a final confirmation everyone confirmed secondary O2 vales are closed1 closed close and we're through one for 8.3 all right so each of the crew just closed those secondary O2 valves on their umbilicals again that was primarily for cooling um during the space walk walk itself suit's still pressurized by that primary and now we're going to start to see uh the pressure tick up inside of dragon uh right after they get the hatch closed they're able to do kind of an initial pressure check cuz again oxygen it's an open loop system with these suits still flowing into the cabin you're able to see positive pressure response showing that the cabin uh the hatch was closed and was sealed uh we'll still do a leak check on our way kind of back back up to our nominal cabin pressure um so we're going to continue ticking up until we're about 8.3 PSI and then we're going to transition into the second phase of our repress um really the difference between repress one repress 2 is how frequently we're injecting atmosphere uh as kind of the the repress is also pretty unique with dragon um we're repressurizing with just nitrogen right now um which is a little bit unique obviously you have nitrogen and oxygen in your atmosphere uh with this we have O2 flowing into the cabin through the suits so we only need to add nitrogen so we're able to just basically add a bunch of that to really start getting your pressure up O2 continues to flow into the cabin through the suits and we're going to continue pressurizing until we're pretty much right back at our 14 right at about our 14 uh or so PSI and we're also looking at what the partial pressure of oxy is cuz we want to make sure the crew takes helmets off and everything that plenty of oxygen in the cabin and then we're going to change that injection rate to just help with the mixing is microgravity everything's harder everything's on hard mode um and you don't just have natural convection so like I mean space station I think I've heard it a bunch of times Mike like you just constant noise of fans that's right almost yeah there's uh you've got to continually recycle that air um and one to help get rid of the CO2 right because as we're taking in that oxygen they're breathing out the CO2 and we need to to get that out of the system which is another important reason to have that air constantly circulating yeah um man that felt really quick that it did that was that was that was really cool to to see them outside for the first time and there they were what they were actually doing out there is a bunch of pretty simple tests as it looked but like this is just learning how the heck do you move cuz like just moving around yeah in micro gravity is tough it is tough SP X we're about 2 and half minutes from T's hand overing around when you're in your short sleeves like we're in inside the capsule and when you put on that space suit uh it it's much more challenging to to move around with that on yeah and what they were really doing was just kind of like you put your hand on on Skywalker and then you're changing your pitch you're doing translation up and down and everything and then the one that that I think is kind of cool is Max reach cuz like just going like that is you know not easy yeah and I think one of the other things I thought was interesting is you heard I think it was Sarah talk about the horizontal rail versus the vertical and how much easier that was for her to grab onto or utilize versus the vertical one so simple things like that you know for us it not a big deal yeah uh but out there in in that uh in the vacuum and in the microgravity environment it does become a a much bigger deal and you and you know Dan and I we've never been in space so we certainly appreciate all of your expertise that you've be able to share with us throughout this morning's operations and uh contributing your two cents yeah no thank you it was great to be here uh just an incredible moment uh not only for the Polaris Dawn for all of SpaceX and and really for for Humanity CU it's just one of those small steps that's taking us that much closer to being that interplanetary species so thank you very much for having me around our pleasure you're welcome back anytime excellent all right good to see you Hopper thanks byee all right so repress is continuing we're a little over four PSI right now again we're going to keep that going up until we're a little over eight and then we're going to change our repress rate uh we're basically just going to be injecting nitrogen for shorter periods of time that's just going to help that atmosphere mix as we get the crew kind of back up to their basically their normal cabin atmosphere that they were they haven't actually been at for the last couple of days cuz we we started this whole process like right after we got on orbit yeah it was almost like we we launched them and gave them two seconds to acclimate and enjoy their cute zero g indicator and immediately stepped into the pre-bath um in order to prepare for today's activity uh and really like you said let them acclimate and uh let their bodies adjust and you know the success of that really was demonstrated today by the fact that we were able to step through uh all of the steps today without having to take the optional uh and available breaks to allow the crew members to adjust during oh sorry I thought we were going to get something there coming in the the tedris in and out so like we'll get it back but um so yeah just the fact that the uh all four crew members were able to just go right along and didn't have to pause um as the option was available I think it's a testament to the preparation that they did before and during one you good we're good good just heard a quick check in from them so we're going to keep keep counting the PSI up until we get to about eight we are going to do another leak check on the way up uh to our nominal cabin pressure uh as you introduced atmosphere you're introducing temperature changes not just pressure changes and so we'll essentially we'll get to a nice pretty stable point when we're at 8 and then we'll let it hang out there for a couple of minutes uh Let The Thermals kind of cancel out um that'll take about 5 minutes to do that uh this obviously has to be done to make sure we've got a really tight seal with that hatch as before we let crew get out of their seats move about the cabin anything like that want to make sure dragon is recovered this is we B we just use dragon as an airlock yeah and actually the info that you were talking about you see it there on your screen live with that Telemetry there in the bottom left and bottom right hand Corners um we can see the Dragon capsule and the suit pressure starting or not starting But continuing to to Rise um it is incredible that we've only been in the Eva for 1 hour and 13 minutes um it flew by so so quickly um C press approaching one PSI on P2 I'm I'm sure for shared and Sarah it flew by even quicker yeah we just heard Jared call down we're coming up on one PSI for po2 so what we're really tracking before we give the crew the go to get out of their suits is both the actual like just the straight up what the absolute pressure is inside um but also what the partial pressure of oxygen is we want to make sure you you don't have a hypoxic environment inside basically you want to get them they're going to be pretty much right back at the atmosphere that we're walking around in right now uh before they get their suits off uh our Eva clock's going to continue to count until we hear the call for Eva uh operations complete from our core Arthur barrial that's going to come uh once we are done with the repress repress operation uh we'll see a couple of uh other things happen with the suits they'll uh do kind of a final wash out of the pure2 environment in the suit using nitrox before they get out Nitro being that same air mixture that you have in your scuba tank uh if got any scuba divers out there uh that nitrogen oxygen mixture um nope still still just there we're just going to keep should hopefully be getting video back from ground stations and by for transition to ress 2 at 8 decimal 3 copy that SpaceX we're following along refres two at 8.3 and so once we transition to repress 2 once we're at about 8.3 PSI will stay there for about 2 minutes and then once the cabin gets up to 9 we're going to pause the repress and we're going to do a cabin leak check this is another kind of critical check we did the initial one after they closed the hatch where you're able to do just kind of let's look at the pressure is it increasing at the rate we expect inside Dragon yes it is um and so we were able to confirm that seals and everything looked good we're going to do another leak check now that we've got more pressure inside Dragon just to really make sure uh that we've got a good seal on that hatch before we finish the operation coming up on 8.3 we should be hopefully just about a minute and a half or so away from ground station so might get those views back inside a dragon yeah it would be it would be great to see them uh post Eva now just like when we were depressurizing the capsule there were there was the option to uh PA refresh che1 we good and yeah that coms we're hearing half PSI before we get the leitor che 9s have a continual checks with all four crew members to make sure that everyone is good um if the answer to one of those checks was no there would be an option in this repress sequence to uh pause possibly to reduce the um you know allow for ear pressure Equalization um but again just like the way that we depressurize now this repress seems to be going uh really smoothly yeah we're just about at 9: I'm going to say we're almost there and then it's going to take up but we're going to pause at 9: we're going to do another cabin leag check so we should hear that momentarily time Eva refes two [Applause] stop Dragon space with you and Eva repress to stop waiting 5 minutes for Thal stabilization that effect we're tracking and pro for your awareness we do a positive refres R we are 30 seconds into the like we mentioned earlier uh right now the this repress is being done with nitrogen um once we get awareness pp2 is 1 decimal 35 halfway there the suits are still flowing that oxygen um and in a few minutes we will begin to flow we'll do a flush uh of of nitrox uh into the suits all right we got our views back there they are it's a little sad to see that forward hatch closed again it's it's got to be really hard when they tell you it's time to go back in yeah just one more minute yep reminds me of when I was a kid swimming in the pool you know time to get out just one more minute I mean it it it speaks to to the professionalism for for Jared for Sarah for the whole crew really like that's that's got to be this is something they've been training for for years and it's got to be really hard not to go for those you know that extra 30 seconds but they're true professionals yep they know there's a timeline good cp2 just passed 1.5 we're a couple minutes into our leak check your your seeing the pressure continue to tick up we've stopped the nitrogen injections but again oxygen coming out of potentially vent line on those suits um and that is why you're going to continue to see the pressure tick up you heard Jared call out the P2 that's gone up that's your partial pressure of oxygen uh we're looking to for that to get to over about 2.6 a little bit higher um and then our final actual like just ambient pressure inside dragon is going to be right around 14.4 so and I mean that's that's a little bit lower than what we're walking around in now but like if you're at a little higher altitude uh state in the country or something that's that's what you might be sitting in right now in your house and that's they haven't been at that pressure since they left her yeah uh but after we get all the way up there we're going to do kind of a final uh flush of the suits using that Nitro uh the K was talking about uh that takes them out of that pure oxygen environment and that's why of the final steps before we'll he hear that call from Arthur evva operations complete and that's when our clock's going to stop uh our space walk did start today at here at SpaceX in Hawthorne California and I'm Dan huitt from the communications team now the first Eva in history was performed in 1965 by Soviet Cosmonaut Alexi leonov followed just 3 months later by the first American spacewalk done by Ed White during the Gemini 4 Mission from those humble beginnings to walking on the surface of the Moon repairing satellites building space stations in orbit space walks are really a core component of human space flight well Evas are wellestablished procedures for NASA and other space agencies this will be the first Space Walk using commercially developed hardware and procedures and spacex's brand new Eva suits which we debuted earlier this year now we've tested extensively in vacuum Chambers here on Earth but this is the first time that the suits will encounter the vacuum of space and on board the dragon spacecraft right now is the Polaris Dawn crew starting off you got Mission Commander Jared Rook isaacman Mission pilot Scott kid potit and for the first time ever we're excited about this two SpaceX employees Mission specialist Sarah Cooper Gillis and Anna Walker Menan who's serving as the mission specialist and medical officer for members of the crew have been orbiting Earth for 2 days since they lifted off from launch complex 39a at Kennedy Space Center on Tuesday September 10th that adds up to about 15 to 16 orbits around the Earth every single day in counting on day two of the mission as you can see there on your screen Dragon fired its forward Draco bulkhead thrusters to send the spacecraft soaring higher than any dragon mission to date reaching the highest Earth orbit ever flown the crew uh topped out at more than 14 00 km breaking the record set by gmany 11 a half century ago when that spacecraft reached 13 excuse me 1,373 kilm this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 since that time dragon has gradually lowered its apog or the highest point in its orbit as the crew got ready for the space walk today they started to Dawn or put on their Eva suit just a little bit of time ago and they've been undergoing a process called pre-breathing with the atmospheric pressure inside dragon has slowly decreased and oxygen has increased to prepare their bodies for the Eva suit environment we're going to dive more into the operations of the spacewalk a little bit later and we're going to be hearing in live communications with the crew throughout so be sure to listen in as those happen yeah it's going to be super exciting to hear that and as far as views goes we'll have dragon's regular internal cameras that we have seen before and up to three exter internal cameras one aimed at the hatch uh kind of like what you see there uh one on Dragon's nose cone uh which actually is the one that's there that's the the the camera on the nose cone and one on the newest piece of Hardware that you see there in that view we that is the Skywalker um which we will come back to shortly we may also have helmet cameras that will give us a firstperson view from the crew which will be incredible now since we are not using starlink to uh and enable views today there will be moments of expected loss of signal due to ground station coverage so those views may be interrupted from time to time but generally we expect to get some great shots today and as of right now we're less than an hour away from the start of the Eva for now though let's learn a little bit more about the mission and our crew the Polaris program is a firstof its kind effort to rapidly Advance human space flight capabilities while continuing to raise funds and awareness for important causes down here on Earth today's goal is to demonstrate critical operational capabilities that are going to serve as those building blocks to help further human space exploration Polaris Dawn Mission has a lot of firsttime objectives so the Polaris program chose a crew of experts who know each other so they can tackle this mission's challenges as a team first up Mission Commander Jared Rook isaacman also served as the commander of inspiration 4 the world's first all civilian Miss to space Jared holds several world records including two speed around the world flights in 2008 and 2009 for the Make A Wish Foundation he has flown in over 100 air shows as part of the Black Diamond jet team dedicating every performance to charitable causes in 2011 Jared co-founded what would become the world's largest private Air Force dren International and that trains Pilots for the US armed forces in addition to his role as CEO of Shift 4 Jared is an accomplished pilot and astronaut with over 7,000 flight hours next up Mission pilot Scott kid potit who served as the mission director of inspiration 4 and he goes by the nickname kid which is also his call sign he's a retired US Air Force Lieutenant Colonel kids served for 20 years in roles that included commander of the 64th aggressor Squadron Thunderbird number four demonstration pilot US Air Force weapon school graduate operational test and evaluation pilot and flight Examiner he's a command pilot with over 3,200 flying hours logged over 400 hours of combat time and following his Air Force career kid served in various roles including vice president of strategy at Shift 4 Mission specialist Sarah Cooper Gillis is a lead space operations engineer here at SpaceX and she's responsible for overseeing our Astronaut training program she helped prepare NASA astronauts for the demo 2 and crew one missions and most recently directly trained the inspiration for astronauts Sarah is an experienced mission control operator who has supported real-time operations for Dragons cargo resupply missions to and from the International Space Station as navigation officer and as a crew Communicator for dragon's human space flight missions in 2015 while studying at the University of Colorado Boulder Sarah started an internship at SpaceX before moving into the Astronaut training program full-time and capping off the Polaris Dawn crew mission specialist and medical officer Anna Walker Menan who serves as a lead space operations engineer here at SpaceX where she manages the development of crew operations and works in mission control as both a mission director and crew Communicator during her time at SpaceX Anna has led the implementation of dragon's crew capabilities and developed critical operational responses to vehicle emergencies prior to SpaceX Anna worked for seven years at Nasa as a biomedical flight controller for the International Space Station she received her bachelor's degree in mathematics and Spanish from Texas is Christian University and her master's degree in biomedical engineering from Duke University everyone on this Mission certainly has the background the qualifications you would want in your crew mates when you're going into space that's clear but let's take a moment now to meet our Polaris Dawn crew in their own words hi I'm Jared isaacman I'm Scott kid potit I'm Sarah Gillis and I am Anna Menan and we're the player St crew I Love This Crew I mean all of them are just so hardworking so smart kid potin over here is our mission pilot talk about a career in the Air Force doing every job as a pilot than than anyone would aspire to achieve and having somebody who has you know been there before and can bring that perspective to our training but also when we're on the mission is just so important we are what we are as a crew because of you you hold us together and you are always there glue glue you are always there predic in what every person needs um and he's needy what our commander Jared I think he is incredibly sharp that's right something I have just witnessed over and over is that he's always like five steps ahead of everybody else he's a Visionary he wanted to make it bigger than just himself going to space it was about uh how we could contribute and support organizations here on Earth uh as well as continue to push the envelope for space exploration so Sarah Gillis the technical confidence we don't get out of any engineering update or brief or go through a procedure or debrief without getting into the weeds and making sure every tea is crossed every guy is is is dotted she holds my feet to the fire uh when when we need to uh understand the systems and the operations it's it's her intellect every time she speaks every word is so thoughtfully prepared that served her in her role as core it served her in her role as a trainer Anna you have this incredible joy that you bring to everyday life it is infectious it makes us all smile feels like she always has this big picture doesn't necessarily always speak up on it but when she does it's like time for everybody to to stop and and listen and then as a biomedic engineer and a background like that inspires like a ton of confidence that you go up there if uh if people aren't feeling right that she's going to be there to take care I cherish all the moments that we've had uh in these experiences and uh we're just so excited to to go to space now that you know a little more about the Polaris Dawn crew let's recap the mission so far and what's coming up next since liftoff and getting to their initial Orbit on day one the crew has been quite busy the crew had a few meals got some rest and spent a few hours demonst ating the Eva suit's pressurized Mobility to verify positions and accessibility in microgravity the crew also prepared the cabin for the Eva and of course had an opportunity to talk to their families and check in as I mentioned earlier on day two dragon proceeded to a high appage of more than 1,400 km higher than any dragon mission to date this was also the farthest from Earth for a crude spacecraft since the last Apollo lunar mission in 1972 in preparation for the spacewalk dragon has executing a series of a apog loing apog lowering phasing Burns by now dragon has lowered itself from the highest apy of the mission of more than 1400 km to about 190 by 700 km above the Earth also on day two the crew was joined on air by some very special guests uh as you can uh see here we uh we are not here but we had patients and families at St Jude Children's Research Hospital um and they they're joined Live While polaron crew member Anna Menan read from her new book kisses from space along with the patients and families at St Jude and his children James and Grace also joined the reading and afterward the crew hosted a Q&A and speaking of St Jude for this Mission the Polaris Dawn crew Enlisted the help of Childhood cancer survivor live to create the missions Zerg indicator while not a St patient herself live met the inspiration for crew and inspired by the mission of St Jude she agreed to share her talent to support P stone is Li and I spell it l and then an apostrophe Mark escalation Park I can tell you anything about space from the miles from Earth to the Sun to every Mission basically I had cancer in 2021 cancer survivor like Haley I really have a passion for wanting to help St Jude and other kids who have those struggles as I had so I first met Liv a couple days after I got back from space at our Splashdown party and I got to meet her family and they told me about her journey that she was on I remember that she gave me a card she had written and it said thank you for helping other kids with cancer like me I hope to go to space like you someday and my eyes just filled with tears whenever I read that basically my one passion is to um be the first child in space Liv was really close with the players Don crew and they asked her to design the Zerg indicator a zerg indicator is like a little plush toy that floats in the air it basically shows that you're in zg they kind of hide it over in the corner and then once you hit zg it'll float up and reveal itself my main idea for asteroid is based on elon's dog POI I I've always loved sheats they've always been really cute and then when I heard got POI I was like done I love her I want asteroid to be for every child and help them see oh asteroid went to space and I can too I can achieve my [Music] dreams we are also flying Liv's original drawing that you see there that was used to design the Zerg indicator which we plan to return to her after it has flown in space and while her design was inspired by the working dogs of St Jude Children's Research Hospital all donations from the sale of asteroid will will be General donations to St Jude the inspiration for Mission helped raise more than $240 million for St Jude Children's Research Hospital and polaron will continue to raise funds and awareness for St Jude while partnering with the organization to provide healthc care in underserved communities around the world now if you want your very own asteroid they are available at shop. spacex.com and polaris.com I did just look Unfortunately they are sold out right now but there are more on the way so be sure to check back at those sites to catch one of your own myself included I missed the first drop so uh I got like I snagged one I got in there I got a kid who nice needs one yeah all right now the first first phase of the spacewalk the preparation actually started just about 2 hours after the crew reached orbit and this is when the pre- breath process started that's when the oxygen levels started to increase incrementally as the actual the cabin pressure inside Dragon was started to get incrementally lower the pre-breathe process is designed to decrease the amount of nitrogen in the body which then reduces the risk of decompression sickness which can happen as atmospheric pressure lowers protocols like this are used for any Space Walk done today and might feel familiar to anyone here on Earth that has gone scuba diving and done a decompression stop after ascending from a pressure of in deep water back up to the surface and to do all this dragon's just been slowly decreasing that cabin pressure that allows the crew to acclimate each time the pressure gets lower as they get ready for the lower pressure they'll be in in the suit during the space walk itself they've got the ability to pause the process if they experience any discomfort but the ear ear equilibrium just kind of naturally adjusts as the pressure decreases it's kind of like when your ears pop when you change altitude on an airplane um all four astronauts are going to be suited for the spacewalk today because Dragon does not have an airlock that's also kind of why the entire cabin is going to be depressurized it's why we have this kind of unique pre-breathe process with this stuff today too all that brings us to now so far the crew has prepared the cabin for vacuum which includes securing all loose items that they don't want floating around they also completed medical checks suit inspections and final checkouts of the oxygen venting and nitrogen repressurization systems after that it was time to put on their Eva suits and now Jared and Sarah will be exiting the spacecraft today while kid and Anna will be supporting from the inside crew in the outer two seats kid and Anna are going to be fully strapped in and then the two in the middle seats Jared and Sarah are just going to be lightly secured ahead of the spacewalk since they're going to be moving around and eventually heading outside as we listening to comms during the Eva you may hear the crew referred to as ev1 which is Jared and ev2 which is Sarah support one is kid and support two is Anna again they will not exit the dragon during the Eva but make no mistake they are very much performing in Eva just the same and their data is being collected as well once everybody's in position the seats are going to get rotated upright generally they stay in the recline position for the majority of the mission but we're going to rotate those upright during the Eva just to give more room to move about after that seat rotation the crew verifies that their heads up display or the HUD on their helmet visors are turned on operating as expected this is how the crew will actually be able to keep tabs in the health of their suits and they'll get some other stats of their suit operation during the spacewalk and that will take us to the first official go noo checkpoint to determine if the Eva can proceed after an operations brief from the SpaceX team the crew will announce their go noo status and and then it'll be time for the spacewalk to begin it's expected to last about 2 hours from the time that O2 begins flowing to the cruise suits until we complete the repressurization of the cabin and just prior to we get to cabin venting pure oxygen is going to start flowing to the cruise suits that's when the Eva clock will start so keep an eye on that and this all gets followed by a suit leak check we'll do the leak checks once those look good Mission Control will start to vent the cabin just removing the air in order to lower its pressure down till we can get to hatch opening next dragon will use its Draco thrusters to reposition itself so that the trunk is facing the sun this will help keep temperatures Communications and spacecraft power stable during The Space Walk at this point the crew should be ready to open dragon's hatch and exit the spacecraft after the hatch gets opened ev1 that's Jared's call sign during The Space Walk he's going to be the first to exit the spacecraft he's going to go outside and he's going to do a series of Mobility tests these are kind of the core component of the spacewalk today it's going to basically take the Eva suit through the paces it's going to take about 15 minutes before he climbs back into Dragon after that ev2 or Sarah will step out into space to perform the same tests of her Eva suit before she then climbs back into dragon in addition to the suit Mobility tests Jared and Sarah will also evaluate dragon's new Skywalker Hardware we'll talk more about that in just a bit and then after she's completed her test Sarah will stand by near the hatch for the actual closing and then at this point after the hatch is closed the Eva is not over the hatch door gets closed and then the cabin has to be repressurized we got to get all that atmosphere back inside after we start introducing that atmosphere we'll do cabin leak checks once those leak checks are complete the crew will return to their seats and the Eva will be complete when the cabin pressure has returned to nominal so for now the crew is suited up and a waiting final checkouts and Eva venting which will bring in dragon to vacuum uh with everything on track we're about 45 minutes or so from the start of the Space Walk and before we get there though we're going to expand the desk a little bit we're happy to be joined by former NASA astronaut Mike Hopkins we were fortunate to have him tune in with us uh during the launch and now we've got him to talk to us a little bit about space walking today good to see you Mike yeah it's great to be back it's great to be back here in H Thor with you tonight on this uh very memorable night for sure yeah absolutely uh now Evas may be new to SpaceX but uh you have participated in five yourself uh while you were on the International Space Station and spent a total of 333 days in space that's that's pretty cool yeah I mean I was very fortunate uh on my two missions Jo the first one was back in 2013 and I uh I went up on a Russian soy use and on that when we had two space walks and the interesting thing about those space walks is they weren't planned uh they were what we call yeah they were a big surprise for us uh contingency Space Walk and of course surprises happen at Christmas because that's when we actually went out the door our second walk was on Christmas Eve and uh that was pretty exciting to to be doing a space walk as everybody was getting ready to celebrate Christmas down just helping deliver presents that's right that's right and then your first play was on the so but your second one you were the commander of crew won I mean that was obviously really huge for everybody here that was big for me I was there with you at Nasa still that was a huge moment that was the first like long duration mission to the space station on dragon and I mean you you really got to know Dragon probably more than anybody because you you actually got to call it home while you were docked up there that's right it I mean I tell you it was quite an honor to to get to be a part of that crew to get to command that crew um and and it was an a great amazing group of people not only uh uh Victor Shannon and suichi but also everybody that that helped get us there at SpaceX and at Nasa but yes you're right Dan um while we were on board we we didn't have enough Cruise stations and actually you can see a picture of uh of where I slept while I was on board for that second mission and uh it was actually quite comfortable uh and one of the best parts about being able to sleep on Dragon is that I had a view I had the window and our other crew quarters did not so I've got some amazing pictures from my time staying in Dragon that's amazing um it's great to have you here I had the pleasure of watching you launch uh in person I was hosting the crew one launch from the NASA press site and it was just so cool to see everything light up and just watch you ascend to the station where the station where you made it your home it was also so great to see you here around campus during your training period um to seeing you here on the Mez having lunch and uh that was really cool and during that time you got to get the SP get to know the SpaceX team pretty well in fact Anna and Sarah uh were two of your Trainers for crew one weren't they they yes and uh you know I got to for the launch we saw some of their videos of training and I I thought it was kind of fun to see see them as trainees yeah and somebody else getting to uh getting to test them all the time so uh yeah it was pretty neat to to get to see that switching it up a little bit because we're we're starting to get some views back from Dragon we've been treated to some pretty spectacular stuff as we were you know all the way out to 1400 km uh we like to talk about something called the overview effect so kind of that first first yeah that oh and we're getting some coms from our crew too yeah nice Space X Dragon radio check clear kid got you loud and clear Doling continues and last though just going to be C C that kid make that Dy all right some some quick C checks we heard kid that Scott po he's going to be one of the support crew in there today so our our first Cals down as we get ready for The Space Walk uh but we're looking out the view we're looking down at Earth that overview effect what's it like the first time you get to space you get to look back and I you can see Horizon to Horizon the whole the whole earth below you you know it's kind of funny Dan because uh the overview effect is definitely real but when I first got to space um on that on that soy use uh gosh how many years ago almost nine years ago um I had this really weird feeling of falling and and so when I looked out that window the first time I wasn't really thinking the big thoughts of an overview effect I was kind of thinking like what is going on with my body right now this that's pretty but oh no um but again fortunately when you have time to be in space you you do have an opportunity to experience that and it is definitely true um you know you'll hear people talking about that that small sliver of atmosphere and you see that and that's what's keeping us alive you you see a World Without Borders uh which is incredible but uh you know one of the experiences of the overview effect that I had was that you know that it gives you that sense of answers but it also for me gave me lot of questions it made me realize that there's a lot of this world I don't really know much about the other other parts other countries other societies cultures languages and and so it sometimes it brought as many questions as it did answers hopefully a bunch of bunch more trips then right right that's right uh now for those of us who have never been to space uh it can be hard to imagine uh looking down from there uh here at Planet Earth um space photographer and author Frank White originally point the term the overview effect in a book of the same name here's a little more on the phenomenon that few of us have yet to experience the overview effect is that sensation or that feeling that you get when you see our whole world from the perspective of being outside of it it ranges the whole Spectrum from like how delicate the Earth may appear because you know it's only this Thin Blue Line that separates this habit aable atmosphere of our home planet to you know the vacuum of space it's hard to comprehend what the impact is going to be when I first see Earth from space it just reminds us of how fragile our planet is one of my roles on this crew is to shoot as much footage as we possibly can so we can bring it back and share it with the world the big picture awareness that you gain from that sort of perspective when you were you know journeying amongst the stars and and see our our entire planet as we know it there outside of your window and kind of the the philosophical and the the many different emotions that it provokes inside of you when you see it that way we have barely begun our journey to explore the worlds around us and that hit me right when I saw the the moonrise around Earth and saying like come on it's been 50 years we got to get back there and we got to get to ours and we got to figure out how to get out of our own solar system and try and figure out what this is all about there's so much incredible footage that crew members have taken from space and that you see from satellites I think it's one of the things I'm looking forward to most on the mission is getting to see the Earth from that perspective I can't wait to share what that experience is but I guess I'll have to let you know once I get back and I mean I I think I speak for a lot of space SE four is next support two is next and then ev1 and two are surely behind copy on that crew status getting a quick quick crew status from kid I yeah I I think I speak for a lot of space SE we we really want to get up there and see that view to feel that effect to experience that um and being able to see it just from dragon and you know pretty soon getting able to see a couple of people go out of dragon for the first time in a space walk I mean spacewalks are kind of like living on the edge with space flight it's it's always really cool it's it's really important for just about any program like what are what are some of the things when you were outside the space station what were some of the things that you were working on Mike yeah so when when I went out I mentioned that first Space Walk is contingency we had a failure and so sometimes when we're going outside it's it's not planned and you have a component that that is no longer working and in this case it was a part of the cooling system external cooling system on station and so we needed to go out and replace this refrigerator size pump module and and so that took us a couple walks to do that other times we're we're going out and we're putting in a new piece of equipment on board um sometimes uh normal maintenance sometimes we're upgrading equipment like uh new solar rays new batteries and and things of that nature and and sometimes you're doing like what uh what the Polaris Dawn crew is going to do today and just checking out the suits and checking out the equipment that that you're going to use in future spacewalks as well now uh with all of the experience that you have up there I'm guessing there might be uh an Eva experience or achievement that you are particularly proud of well I'm I'm uh yeah I'm proud of every of every one of them right when you uh when you get out the door and and then you come back in safely I think every that's what everybody that's what everybody wants to do um basic for awareness we're going to be commanding a couple fans right here you'll hear them run but then we'll also be turning them off no correction requiredby actually uh if I can I'm just going to jump in on that that's actually a very important call that was made you heard them say we're going to turn on some fans because when you're in space you acclimate to the sounds around you of the vehicle and when it changes all of a sudden you're kind of looking around at what was that and so you heard them give them a warning that we're going to turn on some fans yeah and so that they kind of knew what was going so that's actually a great call from the ground there um but uh but anyway going back to those those space walks where I was uh at you know outside and and what are you proud of you're you know it's it takes so much to put these vehicles up into the space and and so when you go out on the space walks and you know that um you're a part of keeping that going a big part of it is you don't want to mess up right because uh people are depending on you and couple people watching over your shoulder that's right and so when you get back in and they call up and they say hey that repair that you just made everything's working looks good station's back up 100% just like okay that's that feels great Dragon Space X our fan commanding is now [Music] complete all right hopefully no surprise sounds in their form so I mean space walks are something that you train the heck out of they they're playing down to like the minute what are you know why like what are some of the challenges you can you can run into when you're outside doing a space walk yeah so I mean one of the first challenges that you're always worried about is the how your suits functioning right because that's what's keeping you alive when you're outside like that so uh there are always you know you're monitoring your suits yourselves people on the ground are monitoring your suits and how that's performing and so those are certainly things that you need to be conscious of and and aware of um and and then when you're out there as well uh there are so many steps that it takes to get through a space walk I mean hundreds and hundreds and hundreds of steps and so it's too much for you to remember and so that's where there's a it's a teamwork between you and the and the ground and so they're making all of those calls hey here's your next step here's what the settings are for these tools and and they're just walking you through the whole process and and so I think that's one of the neat things about spacewalks that uh maybe people don't realize is you know you focus on the on the people actually getting to go out and and do the walk uh but but the team on the ground is such a huge part of that as well uh so on your third fourth subsequent Evas um you know they ex these space walks um they they you train a lot for them beforehand before you even get up in space uh by the time you're on your fifth one it must have been more like a cakewalk it no it never felt like a c walk at at all um you know because it is you know it is a a risky Endeavor right so every time you go out on the spacewalk you're definitely um very very focused and and you never want to let your guard down with it I will say you certainly are are more comfortable with what's going on you're more familiar maybe is a better way to to say that but I think um you can kind of trace it back to experiences down here on Earth for me A lot of times it's my uh Sports background so I'll equate a little bit of going out and playing a football game right before every game you're still nervous right you still got a lot of that energy it was the same thing on my fifth Space Walk Like it was on that first one you know you still have all of that kind of nervous energy as you're getting ready to go out well so right now we're still kind of waiting to get into some of the final preparations for this space walk uh we should be coming up on SE rotation I don't know if we missed it or not but again they're going to be rotating those seats uh to move them upright that's just going to give the crew a little bit extra room to move around as we get into this uh but for now why don't we take a couple of moments and meet Dragon uh Polaris Dawn is spacex's 14th human space flight Mission since 2020 when Dragon became the first private spacecraft to take humans
