We're looking at Earth science, observing our planet. Also space science, looking at the ozone in the atmosphere around our Earth. Also looking at life science. And on a human level, using ourselves as test subjects.

There's a lot of different things that we do during life that could personally harm us and I choose not to stop doing those things.

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.

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.

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.

I have a computer screen near my seat where I monitor the overall health of the vehicle and pick up any problems that might be occurring early on or once we see any kind of a malfunction or anything unusual that's happening, we can look at the data and figure out what that is.
