  The face of Dione is almost fully lit as the Cassini spacecraft flies between the moon and the sun at low phase. With a few hundred pixels of its digital camera, Cassini details dozens of craters a million kilometers away.

This view was acquired at a distance of approximately 1 million kilometers (634,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 9 degrees. Image scale is 6 kilometers (4 miles) per pixel. Dione, at 1123 kilometers (698 miles) across, is the fourth largest of Saturn's moons.

This view looks toward the trailing hemisphere of Dione. North on Dione is up and rotated 7 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 31, 2008.

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.
