As a physician, I understand how important it is to collect data on people so we can understand what's happening with them. I will be in the position to help enable that knowledge.
I've always enjoyed traveling and having experience with different cultures and different people. But it's also a wonderful thing to be able to benefit and enable research, not only in our country but around the world.
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.
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.
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.
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.
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.
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.
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.
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.
Gravity pulls our bodily fluids down, like water in a glass goes to the bottom part of a glass. In space, the water doesn't stay in the bottom of the glass. It distributes itself evenly over time throughout the entire volume of the glass.
Everyone that I've talked to who's been to space has thoroughly enjoyed the experience, and what you often hear them say is: It was great, but we just had to come home.
This has been a great experience for me. The first couple of days you don't always feel too well. You adjust to the fluid shifting, how to fly through space without hitting things or anybody else. But then you get in a groove.
Science, for hundreds of years, has spanned the differences between cultures and between countries.
