  Following Cassini's highly successful flyby of Iapetus in Sept. 2007, the spacecraft repeatedly glanced back at the two-toned moon for some time. As Cassini receded from Iapetus, more and more of the bright trailing hemisphere rotated into view.

This image shows terrain farther west than that visible in PIA08384. Most notably in this view, it can be seen that the dark equatorial terrain reaches onto the moon's trailing side by the same amount on the western and eastern sides.

This view looks toward Iapetus (1,471 kilometers, 914 miles across) from about 10 degrees south of the moon's equator and is centered on 284 degrees west longitude. North is up and rotated 16 degrees to the right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 19, 2007. The view was acquired at a distance of approximately 1.7 million kilometers (1 million miles) from Iapetus and at a Sun-Iapetus-spacecraft, or phase, angle of 32 degrees. Image scale is 10 kilometers (6 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.
