Despite the incredible diversity of Saturn's icy moons, theirs is a story of great interaction. Some of them are pock-marked, some seemingly dirty, others pristine, one spongy, one two-faced, some still spewing with activity and some seeming to be captured from the far reaches of the solar system. Yet many of them have a common thread -- black "stuff" coating their surfaces. "We are beginning to unravel the mysteries of these different and strange moons," said Rosaly Lopes, Cassini scientist...

PASADENA, Calif. -- Cassini will make its only close flyby of Saturn's odd, two-toned, walnut-shaped moon Iapetus on Sept. 10, 2007, at about 1,640 kilometers (1,000 miles) from the surface. This flyby will be 100 times closer than Cassini's 2004 encounter, and will be the last time the spacecraft will aim its instruments at this moon. "Iapetus spun fast, froze young, and left behind a body with lasting curves," said Julie Castillo, Cassini scientist at NASA's Jet Propulsion Laboratory,...

PASADENA , Calif. - NASA's Cassini spacecraft has revealed for the first time surface details of Saturn's moon Hyperion, including cup-like craters filled with hydrocarbons that may indicate more widespread presence in our solar system of basic chemicals necessary for life. Hyperion yielded some of its secrets to the battery of instruments aboard Cassini as the spacecraft flew close by in September 2005. Water and carbon dioxide ices were found, as well as dark material that fits the...

REDWOOD NATIONAL PARK, Calif. (AP) - Researchers have confirmed that a redwood named Hyperion in a remote Northern California forest is the world's tallest tree. Steve Sillett, a forestry professor at Humboldt State University, recently climbed Hyperion and measured it at 379.1 feet, one foot taller than previously thought. Hyperion, which grows in Redwood National Park, edged aside the previous record holder, a 370.5-foot redwood called Stratosphere Giant in nearby Humboldt State Park....

LOS ANGELES -- The ABC television network and sister publishing label Hyperion Books are taking the concept of product placement into a new direction -- by turning an imaginary product into a real one. Producers of ABC's mega-hit castaway thriller "Lost" plan to introduce a new storyline centering on the discovery of a fictitious manuscript that will become the basis for a real-life novel that Hyperion will publish this spring. The book will then be promoted as the work of an author, named...

Cassini performed back-to-back flybys of Saturn moons Tethys and Hyperion last weekend, coming closer than ever before to each of them. Tethys has a scarred, ancient surface, while Hyperion is a strange, spongy-looking body with dark-floored craters that speckle its surface. New images, mosaics and a movie of these bodies are available at http://ciclops.org, http://saturn.jpl.nasa.gov and http://www.nasa.gov/cassini. Images of Tethys taken during Cassini's close approach to the moon on Sept....

NASA -- Cassini performed back-to-back flybys of Saturn moons Tethys and Hyperion last weekend, coming closer than ever before to each of them. Tethys has a scarred, ancient surface, while Hyperion is a strange, spongy-looking body with dark-floored craters that speckle its surface. Images of Tethys taken during Cassini's close approach to the moon on Sept. 24, 2005, reveal an icy land of steep cliffs and craters. Cassini photographed the moon's south pole, a region not seen by NASA's...

JPL -- Two new Cassini views of Saturn's tumbling moon Hyperion offer the best looks yet at one of the icy, irregularly-shaped moons that orbit the giant, ringed planet. The views were acquired between June 9 and June 11, 2005, during Cassini's first brush with Hyperion. Hyperion is decidedly non-spherical and its unusual shape is easy to see in the movie, which was acquired over the course of two and a half days. Jagged outlines visible on the moon's surface are indicators of large impacts...

Many of Saturn's more interesting moons are crusted with ice. The moons are often too small for a radioactive core and internal heating. The bizarre wrinkled surface on one of the moons, Enceladus, may reveal a geologically young age. Astrobiology Magazine -- This Cassini image [right] of Saturn's moon Enceladus shows a region containing bizarre, wrinkled terrain. Enceladus is covered with bright water ice. The part of its surface visible here appears to be largely free of craters --...

JPL -- NASA's Cassini spacecraft is set to cap off 2004 with an encounter of Saturn's ying-yang moon Iapetus (eye-APP-eh-tuss) on New Year's Eve. This is Cassini's closest pass yet by one of Saturn's smaller icy satellites since its arrival around the ringed giant on June 30 of this year. The next close flyby of Iapetus is not until 2007. Iapetus is a world of sharp contrasts. The leading hemisphere is as dark as a freshly-tarred street, and the white, trailing hemisphere resembles...

Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
