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.

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.

The Navy's paid for you to go through school, and then they need doctors to go out and take care of people who are in various different parts of the world. I decided to pay back my time first as an undersea medical officer. I was stationed in Scotland.

Hello from above our magnificent planet Earth.

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.
