The northern and southern hemispheres of Rhea are seen in these polar stereographic maps, mosaicked from the best-available Cassini and Voyager images.

Six Voyager images fill in gaps in Cassini's coverage of the moon's north pole. These maps are updates to the versions released in February 2010 (see PIA12562 and PIA12563 ). These mosaics contain data from Cassini's Jan. 11, 2011, flyby of Rhea.

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 417 meters (1,370 feet) per pixel. The mean radius of Rhea used for projection of these maps is 764.1 kilometers (474.8 miles).

Background Info:

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.
