The northern hemisphere of Saturn's moon Dione is seen in this polar stereographic maps, mosaicked from the best-available clear-filter images from NASA's Cassini and Voyager missions.
This map is centered on the north pole and surface coverage extends to the equator. Grid lines show latitude and longitude in 30-degree increments. The scale in the full-size version of this maps is 153 meters (500 feet) per pixel. The resolution of the map is 64 pixels per degree. The mean radius of Dione used for projection is 563 kilometers (350 miles).
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 in Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
