CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Rhea Releases Enceladus

Two slim crescents smile toward Cassini following an occultation event.

Taken only five minutes after Enceladus (504 kilometers, 313 miles across) first approached the limb of Rhea (1,528 kilometers, 949 miles across), this view shows the bright little moon emerging from behind the larger moon's crescent. (See PIA08229 for the earlier view.)

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on July 4, 2006 at a distance of approximately 1.4 million kilometers (800,000 miles) from Rhea and 1.9 million kilometers (1.2 million miles) from Enceladus. The view was obtained at a Sun-moon-spacecraft, or phase, angle of about 142 degrees relative to both moons. Image scale is 8 kilometers (5 miles) per pixel on Rhea and 11 kilometers (7 miles) on Enceladus.

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.
