T-66: A Long Look at Titan

On this high-altitude encounter, the Imaging Science Subsystem (ISS) acquired high-resolution observations during and after closest-approach, covering territory from the trailing hemisphere at high southern latitudes northeast to near-equatorial Adiri. On the inbound leg, the Visual and Infrared Mapping Spectrometer (VIMS) had the opportunity to do one stellar occultation which will allow the scientists to constrain the composition and the spectral properties of Titan's atmosphere.
