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.

My life is a mosaic, and there's no room in between pieces at all.

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.

Life is a re-discovery.

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.

For me, my life is a journey.
