PROMETHEUS...IMAGE NEVER SEEN BEFORE

Saturn's moon Prometheus

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 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.
