I love the John Glenn model... I may call NASA in 25 years or so, and see if they'd like to send me to Mars.

I suggest taking the high road and have a little sence of humour and let things roll off your back. I think that's very important.

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

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.

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

On a standard space shuttle crew, two of the astronauts have a test pilot background - the commander and the pilot.

You can picture pretty easily if there were a paying passenger aboard a rocket that failed, like Challenger failed. Certainly it would be a tragedy, and a tragedy for the company. They would have a hard time recovering from it.
