>>> NEARLY THREE YEARS AFTER -- MADE HISTORY@INSPIRATION FOR SPACE FLIGHT R, HE IS HEADED BACK TO SPACE. POLARIS IS SCHEDULED TO LAUNCH AUGUST 26th AND IT TOO WILL BE HISTORIC. THE ALL CIVILIAN CREW WILL SPEND FIVE DAYS IN ORBIT INSIDE A DRAGON CAPSULE FLYING HIGHER THAN ANY HUMANS HAVE SINCE THE APOLLO ERA. THEY WILL CONDUCT THE FIRST EVER SPACE WALK USING BRAND-NEW SPACEX SPACE SUITS. ON BOARD, ISAACMAN, THE MISSION COMMANDER, MISSION PILOT, AND SARAH GILLIS AND ANNA MILLEN, BOTH SPACEX ENGINEERS AS MISSION SPECIALISTS. I SPOKE EXCLUSIVELY WITH THE CREW AS THEY WRAP UP TRAINING INSIDE SPACEX'S HEADQUARTERS AND BEGIN TO QUARANTINE. >> WELCOME TO OUR SIMULATOR. WE HAVE SPENT, I DON'T KNOW, PROBABLY HUNDREDS OF HOURS IN HERE OVER THE LAST TWO AND A HALF YEARS. THIS IS WHERE WE DO EVERYTHING FROM SCIENCE AND RESEARCH EXPERIMENTS TO RUNNING THROUGH SIMULATIONS OF LAUNCH AND RE-ENTRY AND THEN ALL OF THE APOLLO 13-LIKE EMERGENCIES THEY CAN THROW AT US. THIS HAS BECOME LIKE A HOME AWAY FROM HOMEFOR US. I THINK IT'S ESPECIALLY SIGNIFICANT BECAUSE JUST A COUPLE DAYS AGO, WE PUT OUR MISSION PATCH ON THE OUTSIDE OF THE SIMULATOR AND SIGNED IT, WHICH IS WHAT YOU GET TO DO WHEN YOU'RE CERTIFIED FOR FLIGHT. FROM HERE, WE'RE HEADING TO KENNEDY SPACE CENTER THE IN JUST A COUPLE OF DAYS AND GETTING READY FUR LAUNCH. >> PART OF THE OBJECTIVE IS TO BE FLYING THREE TIMES FURTHER OUT INTO EARTH ORBIT THAN THE INTERNATIONAL SPACE STATION CURRENTLY IS RIGHT NOW. WHAT HAS GONE INTO THE TRAINING TO BE ABLE TO DO THAT? WHAT DO YOU EXPECT IN TERMS OF SOME OF THE EXPERIMENTS, SOME OF THE TESTING, SOME OF THE HEALTH OUTCOMES? >> GREAT QUESTION. SO, THE TRAINING PROGRAM, WE'VE BEEN AT IT, THIS JOURNEY IS ABOUT TWO AND A HALF YEARS LONG. WE'VE SPENT A LOT OF TIME GOING THROUGH THIS PROCEDURAL TRAINING, CHECKLIST PROCEDURES, WORKING TOGETHER AS A TEAM, CREW RESOURCE MANAGEMENT, HANDLING THE CONTINGENCIES, JUST WORKING TOGETHER IN ORDER TO HAVE A SUCCESSFUL MISSION. ALONG WITH THAT, WE'VE DONE A LOT OF PRACTICAL TRAINING TO GET READY FOR THE EVA. SO, WE'VE DEDICATED A LOT OF TIME, A LOT OF RESOURCES. WE CAME HERE. SPACEX HAS DONE AN AWESOME JOB TO PREPARE US FOR THIS MISSION. AND AS YOU MENTIONED, SETTING -- WE'RE GOING TO CONTINUE TO PUSH THE ENVELOPE, AND SETTING THAT HIGHER ALTITUDE AS AN OBJECTIVE IS CRITICAL TO A SUCCESSFUL MISSION. SO, WE'RE ALL LOOKING FORWARD TO IT AND EXCITED FOR WHAT THE JOURNEY HAS. >> AND SPEAKING OF E.V.A., WE'RE TALKING ABOUT SPACE WALK. THIS WILL BE THE FIRST TIME WE'VE EVER SEEN A FULLY PRIVATE SPACE WALK. JARED, YOU'LL BE DOING THAT. SARAH, YOU WILL BE AS WELL. I REALIZE THE SPACECRAFT IS GOING TO BE VENTED, SO EVERYBODY IS GOING TO BE HAVING THAT EXPOSURE TO SPACE. BUT, SARAH, WHAT'S GONE INTO THIS? WHAT ARE YOU EXPECTING TO GET FROM BEING IN SPACE FOR SEVERAL HOURS? >> YEAH. THANKS, MORGAN. YOU KNOW, THIS ENTIRE OBJECTIVE, THIS SPACE WALK THAT WE'RE HOPING TO ACCOMPLISH HAS BEEN SUCH A TREMENDOUS TEAM ENDEAVOR OVER THE LAST TWO AND A HALF YEARS. YOU KNOW, SPACEX DIDN'T EVEN HAVE AN E.V.A. SUIT WHEN WE STARTED, AND OVER THE LAST DEVELOPMENT WE HAVE FULLY BEEN ITERATING ON THE SUIT DESIGN. AND IT HAS BEEN THIS BACK AND FORTH BETWEEN COMING IN AND TESTING BRAND-NEW JOINTS, BRAND-NEW FEATURES EVERY WEEK. SO, AT THIS POINT WE'VE SPENT PROBABLY WELL OVER 100 HOURS IN THE SUITS. AND I CAN TELL YOU, THEY'RE INCREDIBLE. BUT A LOT OF THAT TRAINING HAS HAPPENED RIGHT HERE. YOU KNOW, ALL FOUR OF US ARE GOING TO GET SUITED UP, PR PRES PRESSURIZED. AND THAT'S WHAT THE SIMULATOR DOES. IT ALLOWS US TO TRAIN END TO END, THE FULL SEQUENCE OF SOFTWARE THAT WE'LL GO THROUGH. AND I DON'T REALLY THINK THERE'S ANY ROCK THAT THE SPACEX TEAM HASN'T LOOKED UNDER AT THIS POINT. NOW THAT YOU'RE SEEING THE CAPSULE, DURING THE SPACE WALK, THIS IS UP ABOVE US IS WHERE WE'LL GO OUT INTO THE VACUUM OF SPACE. SO, WE'LL ALL BE IN THIS VOLUME AND THEN DEPRESSURIZE OUR ATMOSPHERE AND CLIMB UP THROUGH THAT FORWARD HATCH. SO, I THINK IT WILL BE INCREDIBLE, AND I THINK WE'RE READY. >> SPACE IS NOT WITHOUT RISKS. THE BOEING STARLINER SITUATION, SORT OF, SHEDS A LIGHT ON THE RISKS OF TESTING NEW TECHNOLOGY, FOR EXAMPLE. HAS THAT SITUATION CHANGED HOW YOU THINK ABOUT SPACE FLIGHT IN YOUR OWN MISSION? >> YOU KNOW, I THINK WE ARE CERTAINLY NEEDING TO CONTINUE TO EXPLORE. WE CAN'T STOP MAKING PROGRESS AND CONTINUING TO PUSH TECHNOLOGY. YOU KNOW, THERE'S SO MANY CRITICAL OBJECTIVES ON THIS MISSION, AND I KNOW WE'RE REALLY EXCITED TO GET TO THEM. I ALSO KNOW HOW MUCH WORK THE ENTIRE SPACEX TEAM HAS PUT IN TO ENSURING THERE'S ABSOLUTELY NOTHING WE HAVEN'T ASSESSED AND LOOKED AT. SO, I THINK WE'RE ALL READY, THIS SPACEX TEAM, OUR MISSION CONTROL TEAM IS READY. SO, WE'RE READY TO LAUNCH AT THIS POINT. >> SOMETIMES WE JUST ACTUALLY CREATE A NORMAL SIMULATION WHERE NOTHING GOES RIGHT. IN FACT, LIKE, WHEN YOU THINK ABOUT THE LAST TWO AND A HALF YEARS OF DEVELOPMENT AND TRAINING FOR THIS, ALMOST EVERY SCENARIO THAT WE APPROACHED HAS MULTIPLE THINGS THAT ARE GOING WRONG TO, KIND OF, STRESS THE SITUATION AND MAKE SURE WE'RE PREPARED. EVEN YESTERDAY, WHICH WAS A FINAL CONFIDENCE TEST OF THE E.V.A. OPERATION, TWO DIFFERENT THINGS WENT WRONG. SO, I MEAN, THE REALITY IS THAT WHEN THE ACTUAL MISSION COMES TIME TO FLY, MOST OF THESE THINGS IF NOT
