We are starting a project to analyze the visible and infrared spectrum of various satellites of Saturn as observed by the Visual and Infrared Mapping Spectrometer (VIMS) on the Cassini orbiter. We plan to characterize the grain sizes and mixing and layering of water ice, and the characteristics of the non-ice components mixed with the ice. The VIMS is an imaging spectrometer that generates cubes of up to 64x64 spatial coverage and 352 wavelengths (96 wavelengths 0.35-1.05 µm for VIMS-v and 256 wavelengths 0.8-5.2 µm for VIMS-ir). The goal is to start with Enceladus for the ice studies because it shows few contaminants, and with Phoebe and Iapetus, because the non-ice components are well defined by nearly or fully ice-free areas. The first step in this analysis involves the careful calibration of the original cubes to best correct for dark artifacts and calibration issues. Then models of ice, pure or mixed with contaminants will be generated to fit the observed spectra, resulting in pixel-by-pixel maps of grain size(s) and mixing ratios. Optical constants and/or single-scattering quantities will be estimated for the non-ice materials, first from ice-free or nearly ice free areas, to be used in these models.
