Caption NASA:"The Cassini Spacecraft examines the rough Dark-Light Dichotomy of the Terrain on Saturn's moon Japetus. Scientists continue to investigate the nature of this moon's Surface.
Lit Terrain seen here is on the Saturn-facing side of Japetus.

North on Japetus is up and rotated 8° to the left. Scale on Japetus was about 7 Km (about 4,3 miles) per pixel in the original image. The image was contrast enhanced and magnified by a factor of two to enhance the visibility of Surface Features.

The image was taken in Visible Green Light with the Cassini Spacecraft narrow-angle camera on Sept. 13, 2009. The view was acquired at a distance of approx. 1,2 MKM (about 746.000 miles) from Iapetus and at a Sun-Japetus-Spacecraft, or Phase, Angle of 103°".
