I've always enjoyed traveling and having experience with different cultures and different people. But it's also a wonderful thing to be able to benefit and enable research, not only in our country but around the world.

There was a moth in there, and it still had its wings crumpled up, and it was just starting to pump its wings up. Life continues in lots of places, and life is a magical thing.

We've had such thorough training, we've had an excellent team on the ground. With the minor glitches that have occurred, we've been able to take care of them. And the teams on the ground are getting tons of incredible data.

Science, for hundreds of years, has spanned the differences between cultures and between countries.

Other than motherhood, the eight years that I spent at the University of Wisconsin, Madison, I have incredibly fond memories of. It's a beautiful place, with four seasons up in Wisconsin. And really wonderful people.

The microgravity or the very, very low amount of gravity that we have up in space forces some changes in different processes. It forces changes in us as human beings.

Gravity pulls our bodily fluids down, like water in a glass goes to the bottom part of a glass. In space, the water doesn't stay in the bottom of the glass. It distributes itself evenly over time throughout the entire volume of the glass.
