better understand how the human body
adapts to long-duration spaceflight.
That knowledge will play a critical role
in future missions deeper into the solar
system, including the journey to Mars,
for which a round trip is likely to last 500
days or longer. Bone density, muscle elasticity, exercise, and psychological changes
are some of the items that will be studied.
NASA said researchers are also interested
in the effects of extended exposure to radiation above the Earth's atmosphere, and its
impact on cancer.
Kelly was set to retire April 1.
"I'll never be done with space, I'll
always be involved," he said. "I doubt I
would fly again with NASA, after having the
most time in space by any American. We
have so many talented professionals in our
office there's no reason for fly me again, but
I absolutely wouldn't say that I'm 100-percent done. Maybe in the next 20 years you'll
be able to buy a cheap ticket and go for a
little visit."

WHEN HE RETURNED to Earth after spending a U.S. record of 340 consecutive days in
space (and 520 for his career), NASA astronaut Scott Kelly said he was a little bit taller,
a bit wobbly, and longing for a fresh salad.
Kelly's time aboard the International
Space Station was twice the length of a typical mission, and designed in part to measure
the effects on the human body of such a long
time spent beyond gravity.
Because Kelly and his twin brother,
retired astronaut Mark Kelly, both are physically fit, NASA said there is much to learn
from studying them that benefits future space
travelers. Mark Kelly spent 54 days in space
on four NASA missions and piloted the space
shuttle Endeavour to its own retirement.
Scientists said Kelly grew two inches
taller while in space. In the absence of
gravity, the disks in vertebra spring up and
absorb fluids, so astronauts temporarily get
a little bit taller-enough to affect spacesuit
fit. When they return to Earth, however, the
phenomenon quickly dissipates.
Kelly has participated in a variety of
research efforts that will help scientists

Daily living conditions: "I probably spent like five months in
that little box....If you are going to
Mars, having that space that you
spend so much time in is very,
very important, and you need to
make it as perfect as you can-
the air, temperature, entertainment, noise abatement."
A bed: "It's kind of painful, actually. Your body does not respond
that well to gravity, after not having it for so long."
Food: "It's kind of funny. The first
thing I ate was a banana and
as soon as I ate it I recognized
the irony in that. The first thing I
wanted to eat was salad."
Longing for a dip in a swimming
pool: "I didn't have any kind of
running water in a year. There
was nothing like jumping in a
pool of water, it felt great."
Records: "Records are made to
be broken. Pushing the envelope
is what makes society progress.
I'm just privileged to be here."
Space: "I think space is important. It helps the economy grow
and it improves technology. They
never imagined how important
that stuff would be to our future."
Earth: "You can see pollution
over Southeast Asia, the fires
over Southern California, and
weather systems in areas where
they aren't normally [located].
For us to take care of the air we
breathe and the water we drink is
critical. And I do believe we have
an impact on that and the ability
to change that if we make the
decision to."
