We didn't use the shuttle robot arm before, so this has been a training flow to get ready for that.

We're taking up some science experiments, some crystal growth things, we have a refrigerator that carries up some samples, new samples that go into the station, we bring the old ones home; we have a lot of clothing, we have a lot of food-U.S. and Russian food.

I'll be the person using the shuttle robotic arm.

There's a lot of interest from the medical community on how things develop in microgravity, and the hope, later, that is expected to apply to what the changes are in humans as well.

Although I know a lot of the previous shuttle flights, in theory, had their tasks laid out; but there were still some changes that came along for them.

We launch when we're kind of in the same orbit that they are in terms of being matched up in inclination in space, and we're just in a little different altitude.

It's very important to know that we packed it right because it is a safety issue for coming home.
