I have a computer screen near my seat where I monitor the overall health of the vehicle and pick up any problems that might be occurring early on or once we see any kind of a malfunction or anything unusual that's happening, we can look at the data and figure out what that is.

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.

Certainly my parents were a huge influence. They always expected the most out of all of us. And expected us to do our very best. I'm thankful to them for allowing me to do what I wanted to do.

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.

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.

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.

We've had such thorough training, we've had an excellent team on the ground. With the minor glitches that have occurred, we've been able to take care of them. And the teams on the ground are getting tons of incredible data.
