Caption NASA:"The Cassini Spacecraft looks down at craters near the North Pole of Enceladus.
Cratered surfaces on Solar System moons indicate older terrains, while smooth surfaces are generally younger and therefore indicative of processes which eliminated the craters.
See also PIA08353 to learn more about the true nature of these surfaces and the processes at work on this geologically active moon.
The moon's North Pole lies on the Terminator to the right of the craters seen in this image. Lit Terrain seen here is on the anti-Saturn side and Trailing Hemisphere of Enceladus.

The image was taken in Visible Light with the Cassini Spacecraft narrow-angle camera on July 11, 2009. The view was obtained at a distance of approx. 472.000 Km (such as about 293.000 miles) from Enceladus and at a Sun-Enceladus-Spacecraft (or Phase) Angle of 57°.
Image scale is roughly 3 Km (a little less than 2 miles) per pixel".
