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.

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.

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.

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.

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.

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.
