T-71: Here Comes the Sun

During this Titan flyby, the ion and neutral mass spectrometer (INMS) looked at the increasing solar activity in southern latitudes, with closest approach on the dayside near the terminator. RADAR had a southwestern quadrant ride-along synthetic aperture radar (SAR) observation of a poorly covered region in the prime and extended mission, valuable for determining Titan's global shape via SAR topographic measurements. CIRS and ISS monitored Titan clouds and their evolution during the day after closest approach, a so-called "caboose" period.
