I was always fascinated by science-fiction shows, shows like 'Star Trek' and 'Lost in Space.'

It looks like the future's really bright.

I went to the University of Washington as a physics and astronomy major. My other interest, of course, was aviation. I always wanted to be a pilot. And if you're going to fly airplanes, the best place to be is the Air Force.

As you look back at your life, there are just a million different things that have happened, just in the right way, to allow you to make your dreams come true. And you know, someone has all that under control.

When you launch in a rocket, you're not really flying that rocket. You're just sort of hanging on.

Science was something that really caught my attention. It was something I really could sink my teeth into.

Fortunately, I got called down to NASA for an interview. And one thing led to the next, and one day I got that call. I've been here about seven years now and am really enjoying it.
