>>> COMMANDER SCOTT KELLY IS THE
VETERAN OF FOUR SPACE FLIGHTS.
HE'S CAPTURED THE WORLD'S MINDS
AND SPIRITS WHEN HE LEFT EARTH
IN 2014 BOUND FOR A YEAR LONG
STAY AT THE SPACE STATION.
IT WAS TO BE THE SINGLE LONGEST
MISSION FOR AN AMERICAN
ASTRONAUT, 180 DAYS IN SPACE.
AND ALTHOUGH COMMANDER KELLY
MAINTAINED A RIGOROUS EXERCISE
PROGRAM IN SPACE, THE PHYSICAL
TOLL WAS EVIDENT WHEN HE
RETURNED TO EARTH IN 2016.
NOW IN A STUNNING AND PERSONAL
MEMOIR ENTITLED "ENDURANCE, A
YEAR IN SPACE A LIFETIME OF
DISCOVERY" THIS MODERN DAY HERE
R
HER-GIVES A CAN DID LOOK AT HIS
LIFE AND HIS FORMATIVE YEARS.
I WANT TO TALK TO YOU ABOUT SOME
OF THE SPECIFICS OF THIS MISSION
AND SINCE YOU'VE COME HOME.
WHAT WAS THE IDEA ABOUT THIS
MISSION, SPECIFICALLY FOR THIS
MISSION, WHAT WERE THE TOP
THINGS THAT EVERYBODY WAS HOPING
TO GET FROM THIS MISSION?
>> SO, SOMEDAY WE'RE GOING TO GO
TO MARS, HOPEFULLY THAT'S SOONER
RATHER THAN LATER, BUT IT'S
GOING TO BE A LONG TRIP, IT WILL
TAKE OVER 200 DAYS TO GET THERE,
YOU'LL HAVE TO SPEND A YEAR ON
THE SURFACE, IT WILL TAKE A LONG
TIME TO GET BACK.
AND WHEN WE'RE IN SPACE, MAYBE
EVEN ON MARS, THERE'S GOING TO
BE SOME PHYSIOLOGICAL EFFECTS OF
LIVING IN THAT TYPE OF
ENVIRONMENT, IN THIS CASE
REDUCED GRAVITY.
SO WHEN WE'RE IN THAT SPACE
ENVIRONMENT, THINGS HAPPEN TO
OUR PHYSIOLOGY, SIMILAR TO WHEN
WE AGE, BUT AT A MUCH
ACCELERATED RATE, WE LOSE BONE
MASS 1% A MONTH, IF WE DIDN'T DO
ANYTHING ABOUT IT.
THERE'S EFFECTS ON OUR VISION,
WHICH WE'RE TRYING TO
UNDERSTAND.
THERE'S ALSO GENETIC EFFECTS,
THERE'S LOTS OF RADIATION IN
SPACE AND THAT CAN AFFECT US ON
A CELLULAR LEVEL.
AND THAT WAS THE STUDY WITH MY
BROTHER AND I, THIS TWINS STUDY,
LOOKED AT THINGS WE NEED TO
SOLVE IF WE WANT TO STAY IN PACE
FOR LONGER PERIODS OF TIME.
>> NOW THAT YOU'VE BEEN HOME,
WHAT HAVE YOU LEARNED THAT YOU
THINK WE'LL BE ABLE TO UTILIZE
BASED ON YOUR YEAR IN SPACE?
>> A LOT OF THE STUFF ISN'T OUT
YET.
THE STUFF I DO KNOW ABOUT IS
SOMEWHAT INTERESTING.
I DIDN'T LOSE TWICE AS MUCH BONE
MASS IN THIS CASE, IT SEEMS TO
LEVEL OFF.
YOU LOSE A CERTAIN AMOUNT.
>> YOU THINK SIX MONTHS AT ONE
LEVEL, YOU THINK A YEAR IS GOING
TO BE TWICE THAT MUCH.
>> YES, AND IT'S INTERESTING
WHEN YOU HAVE A HYPE POOTHESIS
IT TURNS OUT DIFFERENT.
>> YOU TALK ABOUT IN YOU'RE
BOOK, WHEN YOU CAME BACK, YOU
WERE LIKE, I'M NOT SO GOOD RIGHT
THERE.
>> THE FIRST TIME I WENT FOR SIX
MONTHS.
BUT BEING THERE TWICE AS LONG,
NEARLY A YEAR, THE PHYSICAL
EFFECTS THAT I HAD WERE
DIFFERENT.
I HAD DIFFICULT STANDING, I WAS
REALLY, REALLY SORE AND SO
STANDING UP WAS PAINFUL AND
SOMEWHAT CHALLENGING, I WAS
DIZZY FOR A LONGER PERIOD OF
TIME, I WAS NAUSEOUS FOR A
LONGER PERIOD OF TIME WHEN I'VE
BEEN IN SPACE.
>> THOSE ARE SCARY SYMPTOMS.
>> OH, YEAH.
>> WHEN YOU READ THIS, IS READER
IS CONCERNED FOR YOU WITH THOSE
SYMPTOMS.
>> AND HAD I NOT BEEN IN SPACE
FOR A YEAR, I WOULD HAVE BEEN
LIKE REALLY ALARMED AND PROBABLY
WOULD HAVE CALLED 911, BUT IT
TOOK ME PROBABLY ABOUT EIGHT
MONTHS BEFORE I FELT COMPLETELY
BACK TO NORMAL.
BUT MOST OF THE SYMPTOMS GO AWAY
WITHIN A FEW WEEKS.
>> LAST QUESTION FOR YOU, AS YOU
SAID, HOPEFULLY SOONER RATHER
THAN LATER, MAN IS GOING TO
JOURNEY TOWARDS MARS, IF
SOMEBODY COMES UP TO YOU AND
SAYS, SCOTT, WOULD YOU BE THAT
MAN?
WOULD YOU GO?
>> FIRST THING I WOULD ASK, IS
THE RETURN TRIP PART OF THE
DEAL, IF IT WAS THEN I WOULD
PROBABLY GO.
>> THE BOOK CAN CALLED
"ENDURANCE, A YEAR IN SPACE A
LIFETIME OF DISCOVERY."
THANK YOU FOR SPENDING TIME WITH
US.
>> THANK YOU.
