John Batchelor and I welcomed Dr. Jeffrey Plaut, planetary scientist from JPL, to the program to discuss the recently announced discovery of liquid water under the south polar cap of Mars.  We learned that the classification of liquid water on Mars was not yet final and needed more work for confirmation. Listen to how our guest explained this discovery.  We talked about Martian factors making it likely to be liquid water including the reflections received from ground penetrating radar and what we know about internal Martian temperatures, the Martian gravity, permittivity, salts including perchlorates and more. This was a one segment Hotel Mars discussion.

You can email Mr. Batchelor or Dr. Plaut  through me.  Dr. Plaut can also be reached through his JPL website.  Note that Dr. Plaut was a featured speaker on this topic at the Mars Society Convention.  You can see his talk with his Power Point slides once The Mars Society has archived the program.  Having seen it, I certainly recommend you watch it.
