John Batchelor and I welcomed back Dr. Curt Niebur, NASAs program scientist for Cassini, to update us on the close flyby of Enceladus, one of Saturn's moons. The flyby was 30 miles above the moon's surface and took place approximately 10AM PDT Oct. 28, 2015. Cassini flew through the south pole plumes or seafloor vents of expelled water given that it is believed that Enceladus has an under the ice ocean. The flyby will be able to tell the nature and content of ocean plus much more, including the possible detection of organics. Dr. Niebur also described the north pole area since it was viewed for the first time in recent weeks, revealing a very cracked and crevice filled area. Our guest was asked about the Cassini instruments used to gather the information as it flew through the plumes and we learned that two instruments had to be recalculated to do this mission. Another topic briefly discussed was the use of nuclear power for this mission and why solar power would not have worked. Don't miss what our guest had to say about this and more regarding Cassini and this strange moon of Saturn. Please post your comments/questions on The Space Show blog above. You can email Mr. Batchelor or Dr. Niebur through me at
