Rhea 'R-3' Flyby: A Taste of Rhea

As part of the magnetosphere and plasma science (MAPS) and Cosmic Dust Analyzer (CDA) instruments' high priority Rhea Campaign, the Cassini plasma spectrometer (CAPS) controlled the pointing for the MAPS teams to investigate the interaction between Rhea and Saturn's magnetosphere as Cassini made its third targeted close approach to Rhea. In addition, MAPS scientists will use the data collected to further investigate the tenuous exosphere of Rhea. The imaging science subsystem (ISS) conducted high priority science in the four hours that followed, making a global mosaic of regions such as the large Tirawa basin, any fresh craters, and the equatorial dark bluish spots.
