We have a mid-month bonus episode with Andy Weir, author of the novel The Martian, so memorably adapted in the film starring Matt Damon, and the new book Artemis, which launches today! Our own Brian Keating, author of the forthcoming Losing the Nobel Prize, sat down with Andy to discuss lunar colonization, his approach to world- and character-building, and what he would do if he was in charge of the future of space exploration. Andy will be speaking at the Clarke Center on December 7th (see imagination.ucsd.edu for more details).
