Mars

Mars. The Red Planet. We've all heard of it, but how many of us have actually been there? The answer may surprise you. The answer is none. None of us have actually been there. But that's not going to stop us from talking about Total Recall, Terraforming, One-Way Trips, Biodomes and everything else you need to know about if you want to go to Mars.

Also we solve a problem about a listener's friend who raps all the time.
