CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Flying by Iapetus

Images collected during Cassini's recent low pass over the Saturnian moon, Iapetus, have uncovered telltale signs hinting at the cause of its peculiar visage. [Press announcement here.]

Oct 8, 2007: The Other Side of Iapetus - Cassini captures the first high-resolution glimpse of the bright trailing hemisphere of Iapetus.
Oct 8, 2007: Approaching Iapetus - The slim crescent of Iapetus looms before the Cassini spacecraft as it approaches the mysterious moon.
Oct 8, 2007: A Scene of Craters - This high-resolution view shows a vast range of crater sizes in the dark terrain of Iapetus' leading hemisphere.
Oct 8, 2007: A Complex Transition - The transition region from Iapetusí dark leading hemisphere to its bright trailing hemisphere is a complicated patchwork of craters and highlands, with low elevations filled in by dark material.
Oct 8, 2007: Speckled Surface - Dark material has coated the low-elevation terrain and the interiors of craters in the southern portions of the quadrant on Iapetus that faces away from Saturn.
Oct 8, 2007: The Transition Zone - Soaring above the alien, icy wastelands of Iapetus, the Cassini spacecraft captured a series of high-resolution images of the transition region from dark to bright terrain at southern middle latitudes that have been mosaicked together in this view.
Oct 8, 2007: Towering Peaks of Iapetus - This stereo image, or anaglyph, shows huge mountains on Iapetus, imaged by the Cassini spacecraft during its very close flyby in Sept.
Oct 8, 2007: Spotty Iapetus - At high resolution, terrain in the transition region between bright and dark hemispheres on Iapetus reveals a spotty appearance reminiscent of a Dalmatian.
Oct 8, 2007: Closest View of Iapetus - This mosaic of Cassini images shows the smallest details ever observed on Iapetus.
