Iapetus’ trailing hemisphere in false color (19 April 2007)

Iapetus’ trailing hemisphere in false color (19 April 2007)
Iapetus’ trailing hemisphere in false color (19 April 2007) This view of Iapetus, taken by Cassini on April 19, 2007 from a distance of 2.3 million kilometers (1.4 million miles), is an RGB color composite of raw, unprocessed, uncalibrated images. It has been enlarged by a factor of two. The view shows the trailing or bright hemisphere of the moon. Near the terminator (day/night boundary), slanting dawn light brings out the topography of a concentric impact basin. The limb (edge of the disk) is noticeably lumpy, reflecting the moon's battered past. NASA / JPL-Caltech / SSI / Emily Lakdawalla
