Far out in the Saturn system, a small world refuses to behave. Iapetus spins in a way that should not be so stable, wears a ...

This series of maps of Saturn's moon Iapetus shows how a computer model of migrating ice can explain most features of Iapetus' global appearance. The model starts with Iapetus uniformly covered in ice ...

This map of the surface of Saturn’s moon Iapetus (1,436 kilometers, or 892 miles across), generated from images taken by NASA’s Voyager spacecraft, illustrates the imaging coverage planned during ...

Extensive analyses and modeling of Cassini imaging and heat-mapping data have confirmed and extended previous ideas that migrating ice, triggered by infalling reddish dust that darkens and warms the ...

Although it is no longer uncharted land, the origin of the dark territory of Cassini Regio on Iapetus remains a mystery. Also puzzling is the equatorial ridge that bisects this terrain, and how it ...
