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.

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.

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.

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.

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.
