It's fun to work the robotic arm in part because it's really a team effort.

I realized how important it was to know something about aviation, and it was something I was interested in, so I followed my brother's footsteps and obtained my pilot's license.

Well, with so many space shuttle missions that we've done, I think it's just sort of natural that each one hasn't necessarily gotten the attention that the early ones did.

Don't be afraid to reach for the stars

I tell students that the opportunities I had were a result of having a good educational background. Education is what allows you to stand out.

I'll tell you, being involved in human space flight, it is an emotional endeavor. I think it brings in the highest highs and the lowest lows.

I don't recall any interest in science in particular. It came later in college.
