This image, taken by NASA's Cassini spacecraft, shows Dione's twin craters Romulus and Remus (just above-right of center), like their semi-divine namesakes, standing together. Also seen is Dido, the larger crater featuring a central peak.

Dione From a Distance

Like their semi-divine namesakes, Dione's twin craters Romulus and Remus (just above-right of center) stand together. Dido, the larger crater featuring a central peak, lies just to the southeast on the day/night terminator.

Lit terrain seen here is on the Saturn-facing hemisphere of Dione. North on Dione is up. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 28, 2013.

The view was obtained at a distance of approximately 870,000 miles (1.4 million kilometers) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 77 degrees. Image scale is 5 miles (8 kilometers) per pixel in the original image. This image has been zoomed in by a factor of 1.5 to enhance clarity.

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.
