This map of the surface of Saturn's moon Tethys illustrates the regions that will be imaged by Cassini during the spacecraft's close flyby of the moon on Sept. 24, 2005. At closest approach, the spacecraft is expected to pass approximately 1,500 kilometers (930 miles) above the moon's surface. Tethys is 1,071 kilometers (665 miles) across. The colored lines delineate the regions that will be imaged at differing resolutions, listed in the legend at bottom. The new high-resolution coverage will reveal details on the Saturn-facing hemisphere of Tethys, including parts of the giant Ithaca Chasma canyon system. Imaging scientists also are hoping to obtain images of an ancient ridge east of Ithaca Chasma, as well as a section of terrain just west of the giant rift that appeared to be unusually smooth in NASA Voyager images. This flyby is also focused on gathering high-resolution imaging data of the moon's southern polar region. The map was made from images obtained by both the Cassini and Voyager spacecraft.
