When naming features on other worlds, scientists like to follow themes, and Dione is no exception. Dione possesses numerous features with names from Virgil's "Aeneid." The prominent crater showing a central peak below the center is Dido, a 118-kilometer-wide (73-mile) crater named after the supposed founder of Carthage. The crater just above Dido is Antenor, an 82-kilometer-wide (51-mile) impact crater named after the nephew of Priam who founded the Italian city of Padua. At the upper right is the 97-kilometer-wide (60-mile) impact crater Turnus, which lies at the western end of Carthage Linea, a region of bright, fractured terrain. Dione is 1,118 kilometers (695 miles) across.

The sunlit terrain seen here shows some of the wispy markings on the moon's trailing hemisphere. Cassini revealed that these markings are actually a complex system of fractures.

North on Dione is up and rotated 25 degrees to the left.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 25, 2005, at a distance of approximately 1.1 million kilometers (700,000 miles) from Dione and at a Sun-Dione-spacecraft, or phase, angle of 107 degrees. Resolution in the original image was 7 kilometers (4 miles) per pixel. The image has been magnified by a factor of two and contrast-enhanced to aid visibility.

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.
