Setting Your Sights on Saturn
Cassini surveys a bright landscape coated by dark material on Iapetus. This image shows terrain in the transition region between the moon's dark leading hemisphere and its bright trailing hemisphere. The view was acquired during Cassini's only close fly-by of the two-toned Saturn moon. The image was taken Sept. 10, 2007. (NASA/JPL/Space Science Institute)
