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

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.

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.

I did grow up with a really big interest in math and science; I liked it.

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.
