The Planetary Report
10th Anniversary Issue On the Cover: A Voyager 1 portrait of Saturn appeared on the cover of the first Planetary Report. Ten years later, we print a recently created computer-mosaic of images captured by Voyager 2. These colors were generated by combining images taken through the blue, green and ultraviolet filters on Voyager's camera, giving this image a slightly purplish tint. Four satellites appear with their parent planet; from left to right, Mimas and its shadow on Saturn, Tethys and its shadow, Dione and Rhea.
