It's such a long mission and we get to spend so much time in space... we're doing such exciting research. And I don't want to overemphasize the life science research, but as a physician the life science research that we're doing is extremely exciting.

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.

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.

I feel blessed to be here representing our country and carrying out th research of scientists around the world... I hope you could feel the positive energy that beamed to the whole planet as we glided over.

Whenever I do get to look out, it is glorious. Even the stars have a special brightness.

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.

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.
