Hi Andy, really enjoyed reading "The Martian" and thank you for an awesome read. How did you become interested in writing about space travel, and what was your process for doing research for the novel?

Andy Weir I've always been interested in space and space travel. And I always wanted to be a writer. I just don't remember any point in my life where those weren't both true.

As for the research process:
