We don't do laundry because that requires a lot of water, and water's at a premium up here. Plus, it'd be pretty complicated, I think, to make a space washer, although I guess you could do it.

I don't think people have an appreciation for the work that it takes to pull these missions off, like humans living on the space station continuously for 15 years. It is a huge army of hard-working people to make it happen.

I think was able to do a lot of things here.

I grew up in Hawaii and I think it was easier because we did not have cliques at high school.

I think the more mediocre you are the better you do because people need to think you're their friend, they don't want to be threatened by you, you've got to be warm, you've got to be not too smart, not too pretty, not too anything.

Sleeping here is harder here in space than on a bed because the sleep position here is the same position throughout the day. You don't ever get that sense of gratifying relaxation here that you do on Earth after a long day at work.
