Color processing of Galileo global images of Ganymede
Two different global views of Ganymede's trailing side acquired by the Galileo SSI are presented here: One produced by the German Aerospace Center (DLR; left), and the other produced by unmannedspaceflight.com user OWW (right). In the view on the left, which is a composite of images taken with green, violet, and 1 micrometer filters, the colors are enhanced to emphasize color differences. The enhancement reveals frosty polar caps in addition to the two predominant terrains on Ganymede: bright, grooved terrain and older, dark furrowed areas. The global mosaic on the right combines high- and low-resolution images to create a view with more fine-scale detail. The mosaics are both centered at 306°W at a resolution of 9 kilometers (6 miles) per pixel, and north is up. The images in the DLR mosaic were taken on 29 March 1998 at a range of 918,000 kilometers (570,000 miles).
