A lot of scientists on Earth think of things that they could do in zero g. Things like the way metals cure, for example, and the way fluids react in space can tell us a lot about some of the unknowns we have on Earth.

Space station is, it really is one of the more, if not the most, impressive technological achievement of the modern day, not only in what we've accomplished engineering-wise but what we've accomplished on this international scale, because anybody will tell you that half the challenge is making it all work.

Every time I see documentaries or infomercials about little kids with cancer, I just freak out. It affects me on the highest emotional level... Anytime I think about it, it makes me sadder than anything I can think of.
