This global digital map of Rhea was created using data taken during Cassini and Voyager spacecraft flybys.
The map is an equidistant projection and has a scale of 417 meters (1,370 feet) per pixel in the full size version. The mean radius of Rhea used for projection of this map is 764.1 kilometers (474.8 miles).
This map is an update to the version released in February 2010 (see PIA12561). This map contains data from Cassini's Jan. 11, 2011, flyby of Rhea. This map was created using primarily Cassini images. Six Voyager images fill gaps in Cassini's coverage of the north pole.
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, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
