Now you're coming back to Earth, and things are getting more and more dynamic.

You know, Scooter's going to do the first separation burn; I'm going to do the second separation burn.

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.

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

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.

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

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