Thanks to our modern era, facts are incredibly easy to come by. A few web searches for your subject matter, and you have all the information you could dream of.

Just so we're clear, Mark Watney is who I want to be. He has all the qualities I like about myself magnified without any of the qualities I dislike. Mark Watney isn't afraid to fly.

If someone offered me a free trip to the International Space Station, I would decline. I like Earth. I like the internet. I like Diet Coke. I have cats. I write about brave people - I'm not one of them.

I was born too late to experience Apollo 11, though I do trek to Dad's house every time there's some space event. There's something awesome about crossing your fingers and watching a tense Mission Control room do their thing.

I study orbital dynamics as a hobby. My idea of a good time is sitting down and drawing on that knowledge to imagine a space mission from beginning to end, getting as many details right as I can.

Eventually, while researching, you'll learn something you didn't want to know. Some fact that ruins a plotline you had in mind. The good news is that sometimes, learning all the facts can make for a much more interesting story than you originally had in mind.

I am not a brave man... I do not have the right stuff. Astronauts are really a cut above.

Research into manned spaceflight is shifting from low-Earth orbit to destinations much further away, like Mars and the asteroid belt. But society will have to invent many new technologies before it can plausibly send people to those distances.

I was hired as a computer programmer for a national laboratory at age 15.
