Andy Weir really likes to do research. He’s a software engineer who wrote “The Martian,” which was adapted into a movie a couple years ago starring Matt Damon. Now he has a new book out, “Artemis,” about a colony on the moon. We had him on to talk about the economics behind his fictional world and what it might have to do with moral capitalism.

On Marketplace.org, you can find Molly’s interview with Andy Weir on Marketplace Tech and you can read an excerpt from “Artemis” on our blog. Also on our site, you’ll find links to all those calculations Weir made finding the cost to get to the moon, plus the music video for the song NASA commissioned to honor Neil Armstrong.
