The Visual and Infrared Mapping Spectrometer (VIMS) instrument
onboard the Cassini spacecraft observed the system of Saturn,
acquiring spectral cubes in the range 0.4-5.2 microns. This service
focuses on Saturn satellites, and provides access to calibrated and
ancillary data, computed as described here:

direct links to a larger web site with previews.
