  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 (1,400 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 December 2006. See PIA08343. This map is the first of Rhea to be created using mostly only Cassini images. Six Voyager images fill gaps in Cassini's coverage of the north pole.

The Cassini Equinox 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.

The "Unlabeled Full Size" images (JPEG, PNG, and TIFF) are useful. Thanks for providing these (without the lat/lon/text/etc labeling). However, for Rhea (, the unlabeled image does not match the image as shown in the labeled version. That is, there is null/zero data at the edges (180 longitude) of the unlabeled image while the labeled version does have valid data all the way to the edge. Is it possible the final image is actually available but did not make it to the unlabeled section on your site? (again, this appears to be the case only for Rhea)
