Dione Polar Maps - October 2010
February 16, 2011
The northern and southern hemispheres of Dione are seen in these polar stereographic maps, mosaicked from the best-available clear-filter images from NASA's Cassini and Voyager missions.
Each map is centered on one of the poles and surface coverage extends to the equator. Grid lines show latitude and longitude in 30-degree increments. The scale in the full-size versions of these 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 of these maps 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.
