I don't have any nicknames.

Different astronauts sleep in different ways.

Even though NASA tries to simulate launch, and we practice in simulators, it's not the same - it's not even close to the same.

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.

Rocket science is tough, and rockets have a way of failing.

It takes a couple of years just to get the background and knowledge that you need before you can go into detailed training for your mission.

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.
