If you're trying to get someone who's sick with a fever off of a submarine and it's cold and raining outside, the only way in and out of a submarine, generally, is through a fairly narrow hatch.

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.

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.

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.

Some things are only capable of being done in space. Examples of that are looking at our Earth from that far away, and understanding the entire processes of storms and weather patterns, and oceans, and coastlines.
