Images from Cassini, as it comes to the end of its 13 year exploration of Saturn and its moons:

Saturn's northern hemisphere, seen in 2016.

Saturn's tiny, icy moon Mimas, taken on January 30, 2017. Mimas is about 246 miles wide (396 km).

Mimas and the rings, in an image taken on October 23, 2016.

The north of Saturn's moon Enceladus, capturing this view of two different terrain types. A region of older terrain covered in craters that have been modified by geological processes is seen at right, while at left is a province of relatively craterless, and presumably more youthful, wrinkled terrain. Taken on December 19, 2015.

Saturn's icy moon Dione, with Saturn and its rings in the background, just prior to the mission's final close approach to the moon on August 17, 2015.

Enceladus (313 miles or 504 kilometers across) and Tethys (660 miles or 1,062 kilometers across) lined up. Image made on September 24, 2015.
