That's something that is almost part of being human and I'm certain that will continue.

NASA has to approve whatever we wear, so there are clothes to choose from, like space shorts - we wear those a lot - and NASA T-shirts.

I was always very interested in science, and I knew that for me, science was a better long-term career than tennis.

So I saw many planets, and they looked just a little bit brighter than they do from Earth.

I had both male and female heroes.

For whatever reason, I didn't succumb to the stereotype that science wasn't for girls. I got encouragement from my parents. I never ran into a teacher or a counselor who told me that science was for boys. A lot of my friends did.

It's too bad our society isn't further along.
