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.

Those folks out in the space suits are going to be getting beat up.

So, we have to get up and get pumped up for each day.

Now, I've never flown in space; but the folks who have say that on landing day, you know, you've just spent maybe a week and a half, sometimes two weeks in orbit and you're used to the things happening slowly in space.

Because when we're in space, my job is primarily getting us there and getting us back.

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.

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