JASON CARROLL IS OUT FRONT.
>> Reporter: MARS ONE HAS JUST 
TAKEN ANOTHER STEP TO BRING 
MANKIND WHERE IT HAS NEVER 
STEPPED BEFORE.
MEET THE MARS 100.
JUST 100 CANDIDATES REMAIN IN A 
COMPETITION FOR A SEAT ON A 
ONE-WAY TRIP TO THE RED PLANET.
>> I WANT TO GO TO MARS NOT JUST
TO BE A PART OF HISTORY BUT 
INSPIRE PEOPLE AROUND THE WORLD.
>> Reporter: INITIALLY, MORE 
THAN 200,000 APPLIED FOR THE 
MARS ONE ASTRONAUT SELECTION 
PROGRAM FROM ALL OVER THE WORLD.
A YEAR AGO, THAT NUMBER NARROWED
TO ABOUT 1,000.
THAT'S WHEN WE FIRST MET SIX OF 
THEM. 
>> I WANTED TO GO INTO SPACE 
SINCE I WAS 3 YEARS OLD. 
>> Reporter: OUT OF THIS GROUP, 
JUST TWO ADVANCE TO THE FINAL 
100.
LAYLA ZUCKER, AN ER DOCTOR FROM 
WASHINGTON, D.C. WHO IS, WELL, 
EXCITED.

SPACESHIP!

ARCHITECT FROM VIRGINIA.
HUSBAND AND FATHER OF TWO. 
>> THE WHOLE IMPACT AND 
POSSIBILITY BECOMES A LOT MORE 
REAL AND SHARP AS THE NUMBERS 
GET SMALLER.

NOTHING IS REALLY CHANGED.
IT'S STILL JUST US, THE 
CANDIDATE. 
>> Reporter: BAZ LANSTARP IN 
CHARGE OF THE MISSION AND PUT A 
DECADE OF RESEARCH INTO IT.
THE GOAL?
NOT ONLY TO GET PEOPLE THERE BY 
2025 BUT ALSO TO TELEVISE THE 
FINALISTS AND THEIR TRAINING. 
>> I WANT TO REALLY MAKE CLEAR 
THAT IT IS ABSOLUTELY NOT OUR 
GOAL TO MAKE BIG BROTHER IN 
SPACE.
IT IS OUR GOAL TO SHARE THE MOST
EXCITING STORY OF THE 20th 
CENTURY IN A BEAUTIFUL WAY WITH 
THE REST OF THE WORLD. 
>> Reporter: MARS ONE PARTNERED 
WITH LOCKHEED MARTIN WHICH IS 
CONDUCTING TO LAND IN 2018.
SOME SCIENTISTS NOT ON BOARD 
WITH THE IDEA OF A ONE-WAY TRIP 
AND QUESTION WHETHER MARS ONE 
WILL BE READY FOR LIFTOFF IN TEN
YEARS FROM NOW. 
>> I DON'T KNOW 2025 OR 2030 OR 
2035 ARE REALISTIC, BUT I THINK 
IT WILL HAPPEN.
AGAIN, YOU KNOW, OUR HUMAN 
NATURE IS TO EXPLORE.
>> Reporter: BUT IS EXPLORING A 
PLANET MILLIONS OF MILES AWAY 
WORTH LEAVING FAMILY BEHIND?
WHEN ASKED, HERE'S WHAT CARREY 
TOLD ME LAST YEAR. 
>> I DON'T KNOW IF I HAVE WHAT 
IT WILL TAKE TO TURN MY BACK ON 
MY FAMILY.
BUT THIS IS THE ONLY THING THAT 
WOULD MAKE ME EVEN THINK ABOUT 
TRYING. 
>> Reporter: AND NOW?
>> I TOLD MY DAUGHTER AND SHE 
WAS LIKE, I AM REALLY CONFLICTED
BECAUSE I WANT TO SUPPORT YOU 
AND ON THE OTHER HAND, I REALLY 
DON'T WANT YOU TO GO.
AND MY SON WAS A LITTLE LESS, 
YOU KNOW, LIKE, THAT'S GREAT, 
DAD.
WITH MY WIFE, IT'S
