This global map of Saturn's moon Dione was created using images taken during flybys by NASA's Cassini spacecraft. Images from NASA's Voyager mission fill the gaps in Cassini's coverage.
An extensive system of bright ice cliffs created by tectonic fractures adorns the moon's trailing hemisphere, which is centered on 270 degrees west.
The map is a simple cylindrical (equidistant) projection and has a scale of 153 meters (500 feet) per pixel at the equator. The resolution of the map is 64 pixels per degree. The mean radius of Dione used for projection of this map is 563 kilometers (350 miles). Like the 2008 version of the map (PIA08413), this updated map has been shifted west by 0.6 degrees of longitude, compared to the 2006 version of the map (PIA08341), in order to conform to the International Astronomical Union longitude system convention for Dione.
The Cassini Equinox Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. 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.
