NASA's Cassini spacecraft captured Enceladus above the rings and Rhea below. The comparatively tiny speck of Atlas can also be seen just above and to the left of Rhea, and just above the thin line of Saturn's F ring.
Dione's beautiful wispy terrain is brightly lit alongside Saturn's elegant rings in this image captured by NASA's Cassini spacecraft. The 'wisps' are relatively young fractures on the trailing hemisphere of Dione's icy surface.
Enceladus dramatically displays the contrast between its older and newer terrain as seen by NASA's Cassini spacecraft. This view looks toward the anti-Saturn side of Enceladus. North on Enceladus is up and rotated 36 degrees to the right.
Like a cosmic bull's-eye, Enceladus and Tethys line up almost perfectly for NASA's Cassini. Since they are also at relatively similar distances from the spacecraft, their apparent sizes in this image are a good approximation of their relative sizes.
NASA's Cassini spacecraft captured this view of Saturn's moon Epimetheus (116 kilometers, or 72 miles across) during a moderately close flyby on Dec. 6, 2015. This is one of Cassini's highest resolution views of the small moon.
NASA's Cassini spacecraft spied details on the pockmarked surface of Saturn's moon Prometheus (86 kilometers, or 53 miles across) during a moderately close flyby on Dec. 6, 2015. This is one of Cassini's highest resolution views of Prometheus.
Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. As a result, it appears brighter against the dark night sky as seen by NASA's Cassini spacecraft.
Although Epimetheus appears to be lurking above the rings here, it's actually just an illusion resulting from the viewing angle of NASA's Cassini spacecraft. In reality, Epimetheus and the rings both orbit in Saturn's equatorial plane.
The south polar region of Saturn's active, icy moon Enceladus awaits NASA's Cassini spacecraft in this view, acquired on approach to the mission's deepest-ever dive through the moon's plume of icy spray.
NASA's Cassini spacecraft captured this view as it neared icy Enceladus for its closest-ever dive past the moon's active south polar region. The view shows heavily cratered northern latitudes at top, transitioning to fractured, wrinkled terrain.
NASA's Cassini spacecraft spied this tight trio of craters as it approached Saturn's icy moon Enceladus for a close flyby on Oct. 14, 2015. The craters, located at high northern latitudes, are sliced through by thin fractures.
