The southern hemisphere of Saturn's moon Tethys is seen in this polar stereographic maps, mosaicked from the best-available images obtained by NASA's Cassini spacecraft.
The map is centered on the south pole, and surface coverage extends to the equator. Grid lines show latitude and longitude in 30-degree increments. The scale in the full-size versions of these maps is 293 meters (960 feet) per pixel. The mean radius of Tethys used for projection of these maps is 536.3 kilometers (333.2 miles).
The large Penelope Crater is shown in the lower right of the south pole map, in the southern latitudes of the hemisphere of Tethys that faces backward in its orbit around Saturn. See PIA08149 to learn more.
These maps are updates to the versions released in February 2010 (see Tethys Polar Maps - February 2010 ).
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
