The NASA - Cassini Spacecraft captured this fascinating view of Saturn's moon Epimetheus (approx. 116 Km, such as about 72,036 miles across) during a moderately (---> relatively) close Fly-By that occurred on December, 6, 2015. This is one of Cassini's Highest Resolution views of this small moon.


This view looks toward the Saturn-facing Side of Epimetheus; North is up. The image was taken in Green Polarized Light with the NASA - Cassini Spacecraft's Narrow-Angle Camera. The frame was acquired at a distance of approximately 22.000 miles (such as, roughly, 35.405,48 Km) from Epimetheus and at a Sun-Epimetheus-Cassini Spacecraft, or Phase, Angle of 28°. The mage scale is about 697 feet (such as approx. 212,4456 meters) per pixel.


This frame (which is an Original NASA - Cassini Spacecraft's b/w and NON-Map Projected picture) has been colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Cassini Spacecraft and then looked toward the Saturnian moon Epimetheus), according to an educated guess (or, if you wish, an Informed Speculation) carried out by Dr Paolo C. Fienga/LXTT/IPF, and by using an original technique created - and, in time, dramatically emproved - by the Lunar Explorer Italia Team.
