Weathered organic material once dissolved in Enceladus’ subsurface ocean is coating Saturn’s inner moons, explaining surprising variations in their...

Dione in front of Saturn’s rings. This view, acquired by NASA’s Cassini spacecraft during a close flyby of the icy moon on August 17, is centered on terrain at 7 degrees south latitude, 122 degrees west longitude. Image credit: NASA / JPL-Caltech / Space Science Institute.

NASA Reveals New Close-Up Image of Dione

Nov 27, 2015 by Sergio Prostak

This close-up view of Dione was taken by NASA’s Cassini robotic probe during its flyby of this icy moon of Saturn on August 17, 2015. Dione in front...

This image, taken with Cassini’s narrow-angle camera on September 8, shows Dione (near) and Enceladus (far). Although these moons are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. This view looks toward the leading hemisphere of Enceladus. North on Enceladus is up and rotated 1 degree to the right. Image credit: NASA / JPL-Caltech / Space Science Institute.

Cassini Spies Two of Saturn’s Moons: Dione and Enceladus

Nov 19, 2015 by Natali Anderson

NASA’s Cassini spacecraft has snapped a beautiful photo of two Saturnian moons, Dione and Enceladus. This image, taken with Cassini’s narrow-angle...

This view from Cassini looks toward Dione, with giant Saturn and its rings in the background, just prior to the mission’s final close approach to the moon on August 17. The view was acquired at distances ranging from approximately 106,000 miles (170,000 km) to 39,000 miles (63,000 km) from the icy moon and at a Sun-Dione-spacecraft, or phase, angle of 35 degrees. At lower right is the large, multi-ringed impact basin Evander, which is about 220 miles (350 km) wide. The canyons of Padua Chasma, features that form part of Dione’s bright, wispy terrain, reach into the darkness at left. Scientists combined nine visible light images to create this mosaic view: eight from Cassini’s narrow-angle camera and one from the wide-angle camera, which fills in an area at lower left. The scene is an orthographic projection centered on terrain at 0.2 degrees north latitude, 179 degrees west longitude on Dione. An orthographic view is most like the view seen by a distant observer looking through a telescope. North on Dione is up. Image credit: NASA / JPL-Caltech / Space Science Institute.

Stunning Images from Cassini’s Final Close Flyby of Dione

Aug 21, 2015 by News Staff

NASA’s Cassini spacecraft returned new images of Saturn’s moon Dione during its flyby of 17 August 2015. The probe zoomed in as close as 295 miles...

$This image from NASA’s Cassini spacecraft shows a part of Dione’s surface that is covered by linear, curving features, called chasmata. The Voyager spacecrafts observed Dione in 1980 showing a complex surface structure, with wispy features on its trailing hemisphere. The nature of these features was unclear until 2004, when the Cassini spacecraft showed that they weren’t surface deposits of frost, as some had suspected, but rather a pattern of bright icy cliffs among myriad fractures. One possibility is that this stress pattern may be related to Dione’s orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione. Cassini obtained the image with its narrow-angle camera on April 11, 2015. The view was acquired at a distance of 68,000 miles (110,000 km) from Dione. North on Dione is up.
