stibbons started reading A City On Mars by Zach Weinersmith
I bought this after listening to an interview with the author on ABC's Conversations program. While driving to Parkes to go to an astronomical society meeting.
I really enjoyed the interview, and half a chapter in to this book it's agreeing with me as well. The impression I've gotten so far is that it's a solid if very pop-sci dive in to why we're not settling on the moon or Mars any time soon.
