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.

I grew up watching a lot of the coverage of the early U.S. space program, all the way back starting with Mercury and then through Gemini and Apollo and of course going to the moon as the main part of the Apollo program.

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.

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

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