Question The Cosmos #1: Introduction and Water on MarsHi everyone!  Today we bring to you our inaugural podcast.  Things were a little rough around the edges; once Scott and I get used to working together we will work out the kinks.  First off, I realize I didn't describe RSL's - RSL's (Recurring Slope Lineae) are the flowing water patterns that we observed on the surface of Mars.  This was a topic Scott knows a lot about so he did the majority of the talking, but future episodes we will try to make more of a dialogue and less of an interview.  Also, we are aware of the dropping audio quality in Scott's voice at times - this was due to some lag spikes we got in our conversation.  Once we are both back in Washington state this should go away.  Please feel free to e-mail us your questions for next week, we look forward to hearing from you.Thanks for listening!Fun tidbits:Wiki entry on Martian water flowScientific Article on Martian RSL Flows (abstract)
