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 and the location of the upcoming 28 October 2005 Titan flyby. Labels represent the approximate central longitude of each globe.

The radar swaths are superimposed on a false-colour image made from observations by NASA's Hubble Space Telescope. The top image shows radar swaths from the first Titan flyby, on 26 October 2004, (northernmost) and the second radar pass of Titan, on 15 February 2005 (near-equatorial). The 26 October swath is about 4500 kilometres long , extending from 133 degrees west longitude and 32 degrees north latitude through 12 degrees west and 29 degrees north. The February swath is centred at approximately 30 degrees north and 70 degrees west. The spatial resolution of the radar images ranges from about 300 metres per pixel to about 1.5 kilometres per pixel.

The middle globe shows the radar swath acquired during the third radar pass, on 7 September 2005, close to Titan's south pole. The swath is centred at 12 degrees west and 51 degrees south, with similar spatial resolution to the previous two.

These first three radar passes revealed a variety of geologic features, including impact craters, wind-blown deposits, channels, and cryovolcanic features.

The third globe at the bottom shows the location of the radar swath for the upcoming 28 October flyby. The location of the Huygens landing site is marked in red. 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.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency
