Saturn's Rings Observed with Cassini-VIMS
Abstract
Since Saturn Orbit Insertion (SOI) in July 2004, the Cassini spacecraft has completed over 50 orbits around Saturn. During this time, the Visual and Infrared Mapping Spectrometer (VIMS) has made numerous observations of the rings, including high-resolution multi-spectral scans covering the wavelength range from 0.35 to 5.1~μm, at various phase angles and illumination geometries; spectral imaging at both very low (<1°) and very high (>175°) phase angles; imaging the edge-on rings; and occultations by the sun and several bright stars. In this review we will concentrate on radial variations in the rings' reflectance spectrum, with implications for ice grain size and purity, and on structural features revealed by the VIMS stellar occultation data. Included in the latter are self-gravity wakes in the A and B rings, evident in azimuthal variations in the average transmission as well as in ring microstructure; several unidentified wave trains in the C ring; evidence for a bimodal optical depth distribution in the inner B ring; and anomalous dispersive effects seen in dusty regions such as the F ring and Encke Gap. This work was supported by NASA under a contract with the Cassini-Huygens Project. <P />...
