The science behind Interstellar is interesting, because some of it is absolutely real astrophysics and orbital mechanics, some of it is theoretical physics, and some of it is completely Hollywood. When a science fiction movie is based on plausible science, it's really good.

I am definitely a little more nervous for my colleagues when I'm working at mission control than I am myself, on the shuttle.

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.

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 think it's the entire privilege I had to represent my country. It's not the going to space alone; it's to be part of that endeavour and to contribute a very small part to a very important step toward pushing the frontier.

When you're a little different than others, it takes a little more time to fit in. If you really want to be there, there are no ingredients you need other than effort, perseverance and teamwork.
