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.

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.

I see it as one of my jobs to make sure that, it sounds ridiculous, but to make sure the folks are eating, make sure folks are getting enough fluids, make sure folks are, you know, comfortable in the orbiter.

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

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

And, one thing I definitely enjoyed personally, from a selfish point of view, was exploration and going to places that I had never been to before and learning, you know, meeting the people and getting to know, new sights and sounds, etc.

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