Map of Iapetus - January 2008

January 31, 2008

This global map of Iapetus was created using images taken during Cassini spacecraft flybys, with Voyager images filling in the poles.

The map is an equidistant projection and has a scale of 803 meters (0.5 miles) per pixel. Some territory seen in this map was imaged by Cassini's cameras using reflected light from Saturn. The mean radius of Iapetus used for projection of this map is 736 kilometers (457 miles). The resolution of the map is 16 pixels per degree. This updated map has been shifted west by 4.5 degrees of longitude, compared to the previously released Cassini product (see Map of Iapetus - December 2005), in order to conform to the International Astronomical Union longitude system convention for Iapetus.

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.
