This is one of the two most important Titan encounters for the Imaging Science Subsystem (ISS) in the extended mission. These high (about 7,000 kilometer, or 4,350 mile) flybys were designed to provide very long, low phase, high-resolution views of Titan's surface.
On this high-altitude encounter, ISS will perform high-resolution observations during and after closest-approach along the equator from eastern Belet across the trailing hemisphere to western Senkyo, imaging Senkyo at very low phase angles (less than five degrees). The Composite Infrared Spectrometer (CIRS) captures the farthest north vertical profiles of the extended mission, observing the composition and temperature profile at 70 degrees north, and possibly observing the break up of winter/spring vortex.
