Artist's concept of the Nov. 30 Enceladus flyby

November 30, 2010

The 'E-12' flyby (the 12th targeted Enceladus flyby) is the first in a pair of two flybys with very similar geometries – about 48 kilometers altitude over the northern hemisphere. The second flyby in the pair will occur next month. E-12 is grouped with two south-polar flybys, one that was executed on April 28 earlier this year and one that will occur in May 2012. The Cassini Radio Science Subsystem (RSS) will use this suite of flybys to carefully measure the gravity field of Enceladus and determine the nature of the interior - particularly under the intriguing south polar hot spot.
