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, along with PIA18186 and PIA12593.

This view looks towards the anti-Saturn side of Prometheus. North on Prometheus is up. The image was taken in visible light with the Cassini spacecraft narrow-angle camera.

The view was acquired at a distance of approximately 23,000 miles (37,000 kilometers) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 87 degrees. Image scale is 722 feet (220 meters) per pixel.

Prometheus orbits Saturn just interior to the narrow F ring, which is seen here at top.

Examining Epimetheus
In other Cassini imaging neews, the spacecraft captured a unique close up 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, along with PIA09813.

This view looks toward the Saturn facing side of Epimetheus. North on Epimetheus is up. The image was taken in green polarized light with the Cassini spacecraft narrow-angle camera.

The view was acquired at a distance of approximately 22,000 miles (35,000 kilometers) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 28 degrees. Image scale is 697 feet (212 meters) per pixel.
