It's easy to sleep floating around - it's very comfortable. But you have to be careful that you don't float into somebody or something!

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.

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.

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

The space shuttle is a better and safer rocket than it was before the Challenger accident.

If we want scientists and engineers in the future, we should be cultivating the girls as much as the boys.
