The Martian author Andy Weir is really into Mars. So much so that National Geographic tapped him to be an expert on their series Mars, about what human colonization of the red planet might be like. In advance of the season two premiere, Andy stops by the office to talk about the biggest challenges to living on Mars, methods we might use to get there, and whether he'd go himself. (Spoiler alert: Heck no) Also on this episode, technology editor Alex George explains the hierarchy of Apple products, and the Testing Table makes Ramen Krispie Treats in the microwave.
