We have limited information about the effects of alcohol in space, but there's no doubt that it is a very important cultural feature for many of us.  Chris Carberry, the CEO of Explore Mars and author of "Alcohol in Space" joins us to talk about the role alcohol can play, if not in space survivability, then at least in coping with space travel.

We also discuss the latest efforts to get to Mars and whether we can get there by the 2030's.
