AB: The Cassini targeted flyby of Saturn's moon Iapetus on Sept. 10, 2007 will enable the first detailed study of the composition of this satellite within the context of geologic features and evolution. Detailed maps of the volatiles and components constructed by data from the Visual Infrared Mapping Spectrometer (VIMS) will follow on earlier detections. These materials include carbon dioxide (Buratti et al. Ap. J., 2005), polycyclic aromatic hydrocarbons (PAHS; Cruikshank, Icarus, 2007) and trace ammonia (Clark et al. Icarus, 2007). The flyby offers good coverage of the bright-dark interface, and it should enable observations of compositional markers in low-albedo features (e.g., dark floor craters) on the moon's high-albedo hemisphere. Funded by NASA.
