Science is fun. Science is curiosity. We all have natural curiosity. Science is a process of investigating. It's posing questions and coming up with a method. It's delving in.

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

If they asked me if I wanted to go into space tomorrow, I'd do it in a heartbeat. On the other hand, if they asked me if I wanted to go into training for three years and then go into space again, I'd probably say no.

It's well known that many girls have a tendency to dumb down when they're in middle school.

The view of earth is spectacular from space. Most people imagine that when astronauts look out the window of the shuttle they see the whole earth like that big blue marble that was made famous by the flights that went to the moon. But the shuttle is much, much closer than those astronauts were. So we don't see the whole planet, the whole ball at once, we just see parts of it.

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