I felt very honored, and I knew that people would be watching very closely, and I felt it was very, very important that I do a good job.

Weightless is a great equalizer.

Everywhere I go I meet girls and boys who want to be astronauts and explore space, or they love the ocean and want to be oceanographers, or they love animals and want to be zoologists, or they love designing things and want to be engineers. I want to see those same stars in their eyes in 10 years and know they are on their way!

Suppose you came across a woman lying on the street with an elephant sitting on her chest. You notice she is short of breath. Shortness of breath can be a symptom of heart problems. In her case, the much more likely cause is the elephant on her chest. For a long time, society put obstacles in the way of women who wanted to enter the sciences. That is the elephant. Until the playing field has veen leveled and lingering stereotypes are gone, you can't even ask the question.

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.

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

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