T-109: Mapping Titan’s North Pole in Infrared
During this close flyby of Titan, the Cassini visible and infrared mapping spectrometer (VIMS) used its “push broom” mode to take a high-resolution swath across Titan's North Pole region. This path crossed Punga Mare and (depending on the encounter geometry) Kivu Lacus, looking for composition differences in bright spots, called faculae, and the dunes. VIMS first looked for specular reflection on the northeastern tip of Kraken Mare and across the strait that links Kraken and Ligeia and then acquired a few high-resolution images of the lakes. The instrument also imaged the southern hemisphere to view the evolution of Titan's south polar vortex.
