Astronauts are very professional and when they're preparing for launch, they prepare for it as the most serious endeavor of our lives.

I was born in 1958, the same year NASA was established, which I like to think of as not a coincidence. I was 11 when they landed on the moon, Apollo Eleven. And, of course, everybody in the whole world was watching that. But I can tell you, at that time, nobody ever asked a girl, 'Is that something you want to grow up and do?'

I don't know of any issues associated with alcohol before flight.

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 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.

We are involved in technology development for, you know, missions that we hope to plan that would take us to an asteroid and eventually to Mars.

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