Cassini Imaging Science: Initial Results on Saturn's Rings and Small Satellites.

Images acquired of Saturn's rings and small moons by the CassiniImaging Science Subsystem (ISS) during the first 9 months of Cassinioperations at Saturn have produced many new findings. These include newsaturnian moons; refined orbits of new and previously known moons;narrow diffuse rings in the F-ring region and embedded in gaps withinthe main rings; exceptionally fine-scale ring structure in moderate- tohigh-optical depth regions; new estimates for the masses of ringregionmoons, as well as ring particle properties in the Cassini division,derived from the analysis of linear density waves; ring particle albedosin select ring regions; and never-before-seen phenomena within therings.
