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 (PIA08345), 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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
