John Batchelor and I welcomed back Dr. Linda Spilker to discuss the final days and orbits of the great Cassini Mission orbiting Saturn since 2004.  The end is near when Cassini will dip into the upper part of the Saturn atmosphere, burn up and evaporate to become part of Saturn itself.  During our one segment ten minute discussion, we talked about Saturn's rings and what we have been learning about them.  Also Enceladus which our guest said may end up being the most important component of the Cassini mission given the discovery of the under the surface salt water ocean similar to what we have on Earth.  Lind a said that they can tell that there are organics, ammonia, CO2 and more in the water and that there are hydrogen thermal vents on the ocean floor so Enceladus is a good place to look for life.  Linda talked about the final orbit and demise of Cassini starting Sept. 15 of this year.  Don't miss all of what Dr. Spilker had to say about Saturn, the moons and rings of Saturn and the final days of Cassini.
