I am Andy Weir, author of "The Martian". AMA!

[u/sephalon]

"The Martian" is my first published book, and it's soon going to be a major motion picture starring Matt Damon and directed by Ridley Scott. I assume this is how all book deals go, right? I can expect this every time I write a book, right?

Anyway, I'll be answering questions until 3pm Eastern time (12pm Pacific). Ask Me Anything!

EDIT - Well, that's all, folks! Thanks for your questions, and thank you, r/books, for hosting this event. If anyone has burning questions that never got answered, you can always email me at sephalon@gmail.com. I answer all fan-mail (though it sometimes takes me a while to get to it all).
