Definitely you don't become famous by doing something bad; that's a professional death sentence. You remember that whatever you do, someone will be watching, and you study all the time. It sounds terrible, but you get used to it. I'm 45, and I'm still at school, essentially.

Most people here don't have a wide emotional range. It's just the type of people astronauts are, they're required to be level.

I really believe that, in 500 years, we will still remember the International Space Station, because it will have been the first time, really and truly, that nations put a lot of money, brains, resources, and effort together to build something peacefully, and to work together for the sole and unique purpose of furthering our knowledge and bringing it back to Earth for our mutual good.

Almost everything I do when I approach an operational problem comes from the time I've been in space. It's a way of organizing your thoughts. We use problem-solving; what we call "what-if-ing." What if this happened? What would we do? We go over plan B, C, D, E, F, and whatever else, depending on the criticality of what we're doing. This kind of thing can be applied almost everywhere, even at home.
