Cassini zooms past Dione

The rugged landscape of Saturn's fracture-faced moon Dione is revealed in images sent back by NASA's Cassini spacecraft from its latest flyby. Cassini buzzed past Dione on June 16, coming within 321 miles (516 kilometers) of the moon's surface.

On Aug. 17, the spacecraft will make its final flyby of Dione, diving to within 295 miles (474 kilometers) of the surface. The final Dione encounter will be Cassini's second-closest brush with the icy moon. A December 2011 flyby saw the spacecraft reach an altitude of just 60 miles (100 kilometers) above Dione.

The Cassini-Huygens mission is a cooperative project of NASA, ESA (European Space Agency) and the Italian Space Agency. NASA's Jet Propulsion Laboratory in Pasadena, California, manages the mission for the agency's Science Mission Directorate in Washington. JPL is a division of the California Institute of Technology in Pasadena. The Cassini imaging operations center is based at the Space Science Institute in Boulder, Colorado.
