NASA's Cassini imaging scientists processed this view of Saturn's moon Dione, taken during a close flyby on June 16, 2015. This was Cassini's fourth targeted flyby of Dione and the spacecraft had a close approach altitude of 321 miles (516 kilometers) from Dione's surface.
The bright rings of Saturn can be seen at left, in the background of the image.
North on Dione is up and rotated 44 degrees to the left. The image was taken in visible light with the Cassini spacecraft's narrow-angle camera on June 16, 2015.
The view was acquired at a distance of approximately 48,000 miles (77,000 kilometers) from Dione and at a sun-Dione-spacecraft, or phase, angle of 128 degrees. Image scale is 1,519 feet (463 meters) per pixel.
The Cassini mission is a cooperative project of NASA, ESA (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. 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, Colorado.
