In this episode of the SpaceGeeks podcast, Dan Leone talks to Bruce Bugbee: a real-life space botanist who says a one-way trip to Mars means a one-way trip to a meatless diet. Not surprisingly, he also found a few nits to pick with “The Martian” and the greenness of  fictional astronaut Mark Watney’s thumb.
