Andy Weir:
How would you rate the likelihood that the science about conditions on Mars for humans in your book is purely factual vs. guess work?
Andy Weir
It's as factual as I could make it within our current understanding of Mars. I didn't need a lot of guesswork. We know what Mars is like very well thanks to various probes.
