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.

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.

It looks like the future's really bright.

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

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

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.

Like most kids growing up, I had a very wide interest. I was interested in everything. I tried to take advantage of everything, from the sciences to music to writing to literature.
