Map of Tethys - February 2008
February 20, 2008
This global map of Saturn's moon Tethys was created using images taken during Cassini spacecraft flybys, with Voyager images filling in the gaps in Cassini's coverage.
The map is an equidistant projection and has a scale of 292.5 meters (959.6 feet) per pixel. The mean radius of Tethys used for projection of this map is 536.3 kilometers (333.2 miles). The resolution of the map is 32 pixels per degree. This updated map has been shifted east by 1.5 degrees of longitude, compared to the previously released Cassini product (see Map of Tethys - December 2006), in order to conform to the International Astronomical Union longitude system convention for Tethys.
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.
