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 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 (PIA07778), 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 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.
