Great Dark Spot
Saturn's moon Tethys displays its distinctive dark equatorial band here, along with two sizeable impact craters in the west. The larger crater to the north is Odysseus, which has a diameter (450 ki...
With the Band
Two moons that have profound impacts on the rings, Mimas and Prometheus, are seen here with the F ring.
Cassini's high-gain antenna is able to operate at S, X, Ka, and Ku-band frequencies. In addition to communications (X-band between Earth and orbiter, and S-band from probe to orbiter), radio scie...
This high resolution image of the icy crust of Europa, one of Jupiter's moons, reveals a surface criss-crossed by multiple sets of ridges and fractures.
Ridges and Fractures on Europa
Images taken of Saturn's rings by Cassini immediately after it entered orbit around Saturn have turned up circumstantial evidence that an unseen moon may be orbiting dead center in the narrow Keele...
Fingerprints of an Unseen Moon?
The Cassini spacecraft gazes toward the multiple strands of the ever-changing F ring, also sighting Atlas at its station just beyond the A ring edge. A few faint background stars are visible in th...

The Cassini spacecraft looks down from high latitude over Dione and the system of wispy fractures that coats the moon's trailing side. This view looks toward Dione (1,126 kilometers, or 700 miles ...
This image shows that NASA's Dawn mission detected abundances of hydrogen in a wide swath around the equator of the giant asteroid Vesta. The hydrogen probably exists in the form of hydroxyl or wat...

The Cassini spacecraft watches Pandora, one of the F ring's two shepherding moons, orbiting beyond the thin ring. The small moon can be seen on the left of this image. Pandora (81 kilometers, or 5...
This global map of Saturn's moon Enceladus was created using images taken during Cassini spacecraft flybys, with Voyager images filling in the gaps in Cassini's coverage. The map is an equidistant...

These raw, unprocessed images of Saturn's moon Dione were taken on Dec. 12, 2011, by NASA's Cassini spacecraft. Although Cassini obtained more detailed images on previous flybys of Dione, this was ...

This image from NASA's Dawn spacecraft of asteroid Vesta shows Aelia crater with a larger, more degraded crater to the left. Dark and bright material crops out from Aelia's rim and slumps towards i...
NASA’s Terra satellite caught a glimpse of plumes rising from two volcanoes in January 2018.

From afar, Saturn's rings look like a solid, homogenous disk of material. But upon closer examination from Cassini, we see that there are varied structures in the rings at almost every scale imagin...
