The NASA - Cassini Spacecraft looks at a brightly illuminated Enceladus (caught, this time, in its "Crescent Phase") and examines the (always "relatively speaking") young and smooth Surface of its Leading Hemisphere. Note that only a few Impact Craters are clearly visible and only the one located in the Northern Hemisphere of Enceladus - look towards the center of the frame - appears sizeable); also the tormented (and, as far as we know, "extremely hyperactive") South Polar Regions of this beautiful Saturnian moon can be appreciated in this picture.

North on Enceladus is up and rotated of about 21° to the right. The image was taken in Visible Light with the NASA - Cassini Spacecraft narrow-angle camera on November, 6, 2011. The view was obtained at a distance of approx. 67.700 miles (such as about 109.000 Km) from Enceladus and at a Sun-Enceladus-Cassini (or Phase) Angle of 21°. Image scale is 2130 feet (such as 649 meters) per pixel.

This frame 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 outside, towards the Saturnian moon Enceladus), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
