  Cassini continues to image terrain on Iapetus that is progressively eastward of the terrain it has previously seen illuminated by sunlight.

The region seen here was imaged in reflected light from Saturn at excellent resolution in the close flyby on New Year's Eve 2004 (see PIA06168).

This view looks toward the equator of Iapetus (1,471 kilometers, 914 miles across) on the moon's Saturn-facing side. North is up and rotated 11 degrees to the right.

The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Nov. 27, 2006 at a distance of approximately 2 million kilometers (1.2 million miles) from Iapetus. Image scale is 12 kilometers (7 miles) per pixel.

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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. 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.

I agree,Iapetus is one of the most interesting moons of Saturn (and Cassini has in store one Iapetus flyby this year).

Iapetus is one of the most fascinating Moons of Saturn. The Ridge, the sharp edges between the differently colored hemispheres are THE mystery for me.
