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.

Life continues in lots of places, and life is a magical thing.

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.

Life science research can be done on multiple platforms. Since we have a very small number of people flying into space, the more people you have, the better.

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.

Gravity is one variable in a lot of scientific processes. If you can remove gravity or minimize its effect, then you can understand the other processes that are going on.

Things are going very smoothly. As expected, there are some minor glitches, and the eight minutes that it took us to get to orbit, we trained months and months for, and didn't have to use any of that preparation, other than being aware and ready.
