The view of Earth is spectacular.

One thing I probably share with everyone else in the astronaut office is composure.

I have a lot of common sense. I know what needs to be done and how to approach it. I have an ability to work with people on large enterprises.

The astronauts who came in with me in my astronaut class - my class had 29 men and 6 women - those men were all very used to working with women.

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

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.

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.
