And, that's what I truly believe that we're doing when we're advancing scientific knowledge is we're someday making the world better. Not only for our children, but for all people after that.

I could do exploration in this particular career field, and it was a goal that, even if I didn't reach it, it was so high it seemed almost impossible, but even if I didn't reach it, I would still have a good time and a very satisfying career.

I worked for some very good people who have helped me along the way and actually enabled me to have the opportunity to be selected to join the Astronaut Corps.

That's what Hubble can do for us. It can tell us whether the universe is expanding forever or if one day it's going to come back together.

So, I decided that whatever I was, wanted to do with my life, it would have to do, it would have to have something to do with the exploration and doing new things.

Being in space, I'm really looking forward to working with this team of folks that I'm with.
