I enjoy traveling and seeing new places - especially places where I can go hiking.

Why did I want to be an astronaut? That's not an easy question to answer because I know a lot of kids want to be astronauts when they grow up but it stuck with me and I think just maybe growing up in Houston and always having the astronauts and the Johnson Space Center in my backyard, I was always aware of the space program.

Houston's a very big town. It's changed a lot over my lifetime, it's quite a bit bigger now than it was when I was growing up, but it's a fantastic city. I know a lot of people perhaps don't give it the credit it's due but it's a wonderful city that's got absolutely fantastic restaurants.

Well, I was quite young when we first walked on the moon; I had just turned four, but I did watch it on TV. I think that just set the seed right then that that would be a really interesting thing to do.

Growing up in Houston I did go through the public school system. I went to Parker Elementary, Johnston Junior High and Westbury Senior High.

Sometimes you can have too much information. You keep gathering information and never bother to find out what the real answer is.
