Different astronauts sleep in different ways.

For quite some time, women at NASA only had scientific backgrounds.

The view of Earth is spectacular.

I do a lot of running and hiking, and I also collect stamps - space stamps and Olympics stamps.

I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

I never went into physics or the astronaut corps to become a role model. But after my first flight, it became clear to me that I was one. And I began to understand the importance of that to people. Young girls need to see role models in whatever careers they may choose, just so they can picture themselves doing those jobs someday. You can't be what you can't see.

Because I was a tennis player, Billie Jean King was a hero of mine.
