Talk Abstract: During its “Grand Finale,” the Cassini mission studied a never-before-explored region very close to Saturn. The spacecraft has taken ultra-close images of the planet’s rings and clouds, while revealing new details about its interior and the origins of the rings. After 22 of these week-long orbits, on September 15, 2017, the spacecraft plunged into the giant planet’s upper atmosphere, where it burned up like a meteor, ending the epic mission to the Saturn system. Bill Possel will describe the history of Cassini as well as the planning and execution of the Grand Finale. The University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics (LASP) built and operated Cassini’s UltraViolet Imaging Spectrograph (UVIS) instrument.
