T-75: The Interaction of Titan’s and Saturn’s Magnetospheres

T-75 is one of the two most important and unique Titan flybys in the entire extended mission for two of Cassini's non-imaging teams. The radio and plasma wave science (RPWS) instrument team and the Cassini plasma spectrometer (CAPS) instrument team will use the data from this flyby to study how Titan's and Saturn's magnetospheres interact with each other. CAPS controlled the spacecraft's pointing for an entire day, starting 12 hours prior to closest approach. This lengthy interval allowed both instruments to establish context for their observations.
