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.

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.

This has been a great experience for me. The first couple of days you don't always feel too well. You adjust to the fluid shifting, how to fly through space without hitting things or anybody else. But then you get in a groove.

There are some very significant changes in the way the fluids are distributed in our body, the way our heart functions initially, and as well as our bone and muscle.

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.

Certainly my parents were a huge influence. They always expected the most out of all of us. And expected us to do our very best. I'm thankful to them for allowing me to do what I wanted to do.

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.
