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 mission.
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 500 feet (153 meters) per pixel. The resolution of the map is 64 pixels per degree. The mean radius of Dione used for projection of these maps is 350 miles (563 kilometers).
The northern maps are updates to the versions released in October 2010 (see PIA12815). There were no new data for the southern hemisphere, so the October 2010 versions of the southern maps (PIA12816) are included here unchanged.
The Cassini Solstice 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.
