Hello from above our magnificent planet Earth.
We trained for a lot more malfunctions than any ever happen.
Science, for hundreds of years, has spanned the differences between cultures and between countries.
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.
I can't think of anything that's as exciting as I'm sure this mission will be, and actually being in space. But, we did some training as a crew together.
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.
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.
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.
Gravity is one variable in a lot of scientific processes. If you can remove gravity or minimize its effect, then you can understand the other processes that are going on.
