Saturnian system. These data provide information otherwise
unattainable regarding the properties of the icy outer layers (esp.
Europa and Io), discrimination between competing hypotheses
of geologic origins (on Triton, Ganymede, Europa, and
Enceladus for example), and in some cases the thermal histories
of these bodies (esp. Ganymede and Dione). The morphology
and topography of impact craters, volcanoes, faults, and other
geologic features and province serve as probes into the interiors
of these bodies. These data are available on request for use in
mapping and modelling of geologic and geophysical processes.
