The great thing about being an astronaut is you kind of get to do a little bit of everything. I mean, we're going to ride a rocket uphill.

I was interested in flying beginning at age 7, when a close family friend took me in his little airplane. And I remember looking at the wheel of the airplane as we rolled down the runway, because I wanted to remember the exact moment that I first went flying... the other thing growing up is that I was always interested in science.

As a physician and as a pilot, I think it lets me be a pretty good translator having one foot in the medical world and one foot in the flying world. Sometimes when the medical guys come in and speak medical stuff to the pilots, the pilots really don't know what they're saying.

As much as we've enjoyed it up here, we're also starting to look forward to seeing all the people back on Earth that we miss and love so much.

Ambitious and thought-provoking, Higher Education in America represents an informed and informative addition to ongoing debates at the national, state, and institutional levels about the aims higher education ought to aspire to and how best to achieve them.

The views of the Earth are really beautiful. If you've ever seen a space IMAX movie, that's really what it looks like. I wish I'd had more time just to sit and look out the window with a map, but our science program kept us very busy in the lab most of the time.

I remember growing up thinking that astronauts and their job was the coolest thing you could possibly do... But I absolutely couldn't identify with the people who were astronauts. I thought they were movie stars.
