A Cassini Radar Retrospective Of Titan
This set of images shows the areas mapped so far on Saturn's moon Titan by the Cassini radar mapper using its synthetic aperture radar imaging mode. Labels represent the approximate central longitude of each globe. The radar swaths are superimposed on a false-color image made from observations by NASA's Hubble Space Telescope. The top image shows radar swaths from the first Titan flyby, on Oct. 26, 2004, (northernmost) and the second radar pass of Titan, on Feb. 15, 2005 (near-equatorial). The Oct. 26 swath is about 4,500 kilometers long (2,800 miles), extending from 133 degrees west longitude and 32 degrees north latitude through 12 degrees west and 29 degrees north. The February swath is centered at approximately 30 degrees north and 70 degrees west. The spatial resolution of the radar images ranges from about 300 meters (980 feet) per pixel to about 1.5 kilometers (0.93 miles) per pixel. The middle globe shows the radar swath acquired during the third radar pass, on Sept. 7, 2005, close to Titan's south pole. This swath is centered at approximately 52 south latitude and 11degrees west longitude. The spatial resolution of the radar images ranges from about 300 meters (980 feet) per pixel to about 1.5 kilometers (0.93 miles) per pixel. The third globe at the bottom shows the location of the radar swath for the Oct. 28 flyby. The swath is centered at 7 degrees south latitude and 250 degrees west longitude, with similar spatial resolution to the previous three flybys. The location of the Huygens landing site is marked in red at the far right. The overlap between the Huygens data and the radar data will give new clues to the nature of the surface seen by the Huygens probe, which landed on Titan in January 2005. These combined radar passes reveal a variety of geologic features, including impact craters, wind-blown deposits, channels and cryovolcanic features.

Graceful Lanes Of Ice
Pasadena CA (JPL) Nov 16, 2005The dark Cassini Division, within Saturn's rings, contains a great deal of structure, as seen in this color image. The sharp inner boundary of the division (left of center) is the outer edge of the massive B ring and is maintained by the gravitational influence of the moon Mimas.
