Well, my father was in the Army and we traveled quite a bit when I was growing up, and I thought that I would like to have a military career, although I was drawn more towards the Navy.

I like the opportunity to travel the world and work in close company with other people.

I would love to see the world's space programs continue toward sending humans to an asteroid or to Mars, with, of course, a full plan in place to bring them back. That excites me. And one of the things that excites me most about space is that we can go up there and put spacecraft in orbit with sensors that will help us measure the health of our planet, which is becoming particularly important. Our planet needs to be observed.

You're in orbit over the Earth. And suddenly it's very, very quiet. It's dramatic. You realize you're floating in the straps in your chair. And you take off your seat belt and float over to the window and look out, and you realize, "I'm not looking at a picture, here." I couldn't process it all. Even if I forget everything else in my life, that will stay with me, burned into my brain until the day I die.

It is a challenge to have your launch date slip continuously.
