Dione and Enceladus
December 5, 2005
This fanciful view spies the Saturnian moons, Dione and Enceladus, from just beneath the ringplane. Enceladus (505 kilometers, or 314 miles across) is on the near side of the rings with respect to Cassini, and Dione (1,126 kilometers, or 700 miles across) is on the far side.
Saturn's shadow stretches beyond the outermost reaches of the main rings, causing them to disappear at left.
The image was taken with the Cassini narrow-angle camera using spectral filters sensitive to polarized green light on Oct. 15, 2005 at a distance of approximately 2.1 million kilometers (1.3 million miles) from Dione and 1.5 million kilometers (900,000 miles) from Enceladus. The image scale is 12 kilometers (7 miles) per pixel on Dione and 9 kilometers (6 miles) per pixel 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 mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
