Adam Steltzner and the panspermiatic lineae.
Water on Mars! By sheer serendipity the whole SYJ crew meet up with Adam Steltzner from NASA's Jet Propulsion Laboratories, just hours after NASA makes one of the most important announcements of all time - that Mars still has flowing water (and so possibly, life) right now! At JPL, Adam is lead EDL engineers (a.k.a. landing guy) for the Spirit, Opportunity and Curiosity rovers on Mars do he had a lot to say about this. But the comedians spend half the time talking about The Martian and Adam's epic hair.
