Well, we spend an awful lot of our time working and doing experiments. It's very busy up on the shuttle.

I've spent my whole life not talking to people, and I don't see why I should start now.

The best advice I can give anybody is to try to understand who you are and what you want to do, and don't be afraid to go down that road and do whatever it takes and work as hard as you have to work to achieve that.

The thing I'll remember most about the flight is that it was fun. In fact, I'm sure it was the most fun that I'll ever have in my life.

But when I wasn't working, I was usually at a window looking down at Earth.

For a long time, society put obstacles in the way of women who wanted to enter the sciences.

I slept just floating in the middle of the flight deck, the upper deck of the space shuttle.
