I had always been interested in the space program, and I didn't know if I could be an astronaut like I'd dreamt about when I was a little kid - to me it sounded kind of silly, someone grow up to be an astronaut - but, when I was in my 20s, I thought maybe I can get a job with NASA or a contractor, do something with the space program.

I saw this movie 'The Right Stuff' when I was in college, and it really rekindled my interest in being an astronaut. I started taking those steps, and then I realized it would be the chance of a lifetime. It would be a dream life: not just a job, but the whole life.

Being outside during the space walk, the view of the Earth is just spectacular, and getting a chance to do that is just unbelievable, everything about it. You are going around the Earth at 17,500 miles an hour, so you have 45 minutes of sunlight followed by 45 minutes of darkness. You do a lap every 90 minutes.

It is only when you watch the dense mass of thousands of ants, crowded together around the Hill, blackening the ground, that you begin to see the whole beast, and now you observe it thinking, planning, calculating. It is an intelligence, a kind of live computer, with crawling bits for its wits.

As an astronaut, when you're getting ready to go out of that hatch, you know that's the pinnacle of both your career and your life. The view completely blows you away. The real challenge is getting past the excitement and getting focused and down to work.
