NASA dixit:
“November 30, 2010. This Cassini narrow-angle camera image — one of those acquired in the survey conducted by the Cassini imaging science team of the geyser basin at the south pole of Enceladus — was taken as Cassini was looking across the moon’s south pole. At the time, the spacecraft was essentially in the moon’s equatorial plane. The image scale is 1280 feet (390 meters) per pixel and the sun-Enceladus-spacecraft, or phase, angle is 162.5 degrees. The image was taken through the clear filter of the narrow angle camera, 1.4 years after southern autumnal equinox. The shadow of the body of Enceladus on the lower portions of the jets is clearly seen.
Post-equinox images like this, clearly showing the different projected locations of the intersection between the shadow and the curtain of jets from each fracture, were useful for scientists in checking the triangulated positions of the geysers.”
“After almost 20 years in space, NASA’s Cassini spacecraft begins the final chapter of its remarkable story of exploration: its Grand Finale. Between April and September 2017, Cassini will undertake a daring set of orbits that is, in many ways, like a whole new mission. Following a final close flyby ...
