Saturn's moon Dione is captured in this view from NASA's Cassini spacecraft, half in shadow and half in light. Sinuous canyons carve interconnected paths across the moon's icy landscape. Subtle variations in brightness hint at differences in composition, as well as the size and shape of grains in Dione’s surface material, or regolith.
Cassini spent more than a decade at Saturn studying Dione (698 miles or 1,123 kilometers across) and the planet's many other moons as part of the quest to understand how the moons formed and evolved, and how they are connected.
This view looks toward the side of Dione that faces away from Saturn. North is up and rotated 59 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 22, 2017.
The view was obtained at a distance of approximately 224,000 miles (360,000 kilometers) from Dione. Image scale is 1.4 mile (2.2 kilometers) per pixel.
The Cassini spacecraft ended its mission on Sept. 15, 2017.
The Cassini Solstice Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
