I'd love to go back to space, I don't know any astronaut who doesn't want to.

I never declared I wanted to be an astronaut, as I considered that was presumptuous.

I didn't really decide that I wanted to be an astronaut for sure until the end of college.

I did not come to NASA to make history.

I'm not fond of biographies. I don't like writing about myself.

Any astronaut can tell you you've got to do everything you can to learn about your life support system and then do everything you can to take care of it.

Well, for me it really wasn't a case of deciding to be an astronaut.

I cannot join the space program and restart my life as an astronaut, but this opportunity to connect my abilities as an educator with my interests in history and space is a unique opportunity to fulfill my early fantasies.

When we meet people who are astronauts or deal in astronomy, it's always really fascinating.

I was born in 1960 and can still tell you the name of every astronaut from Mercury to Apollo. If I had a chance, I'd love to go into space on one of the privately developed space crafts.
