"Mind is a lot more important than body. So is your ability to think in 3-D and imagine how to move things
in a different way than on earth. The second time I went to the station, it felt like coming home. I got
comfortable much more quickly. Everything is lifted while you're up there, so you look younger. Being back
on earth is not pleas ant at first. Moving around is difficult, like playing basketball. But I had my physical
training for about a month after my retum."
Sunita Williams
Age: 43
Astronaut since: 1998
Space time: Six months on the space station in 2006-2007, including more than 29 hours of space walks.
"I learned after about a week how to fly beautifully without going too fast or shaking around. I had a hard
time remembering how to walk, I prefer flying! When you have that idea of being far away anti looking back
at the planet, you don't see any cit- ies or countries. You see a very quiet place. Just as Gandhit-the Father of
the Na- tion in India, once explained the feeling of oneness in all of us. Seeing our planet from space, you
understand that."

"No matter how I was situated (处于…位置) the first day, it seemed that my body was upside down
(颠倒着). That might have been because all your blood comes to your head. And what memory do you have
in that situation? It's like when you're kids, hanging upside down."
