NASA Cassini spacecraft images of Saturn's diaphanous G and E rings are yielding new clues about their structure and formation. A sequence of recent Cassini images, which has been made into a brief movie, shows an arc of bright material looping around the inside edge of the G ring, a tenuous 7,000-kilometer-wide (4,400 miles) band of dust-sized icy particles lying beyond the F ring by 27,000 kilometers (16,800 miles). Cassini passed between the F and G rings during its insertion into orbit...

JPL -- On its recent close flyby of Mimas, the Cassini spacecraft found the Saturnian moon looking battered and bruised, with a surface that may be the most heavily cratered in the Saturn system. The Aug. 2 flyby of Saturn's 'Death Star' moon returned eye-catching images of its most distinctive feature, the spectacular 140-kilometer diameter (87-mile) landslide-filled Hershel crater. Numerous rounded and worn-out craters, craters within other craters and long grooves reminiscent of those...

How old is Titan's surface? For years, Saturn's moon Titan was thought to have mastered the cosmetic surgery of the cosmos, with barely a mark or wrinkle to betray its true age. Close-up views provided by Cassini instruments show that Titan is nearly as flawless as it seems from a distance, with only two impact craters found so far. A world with a more youthful surface may be more likely to harbor life. Astrobiology Magazine -- Thanks to a thick veil of orange smog, the surface of Titan has...

JPL -- The Cassini spacecraft is about to embark on a new mission phase that will give it a ringside seat at Saturn -- literally. After concentrating on flybys of the stately planet's moons since arriving last year, Cassini will begin five months of extensive study of Saturn's magnificent rings. Knowing how the rings form and how long they have been there is a central question for the Cassini mission. Cassini will view the rings on their lit and unlit faces, both toward the Sun and away from...

JPL -- NASA's Cassini spacecraft continues making new and exciting discoveries. New findings include wandering and rubble-pile moons; new and clumpy Saturn rings; splintering storms and a dynamic magnetosphere. "For the last seven months it has been a nonstop, science-packed mission. It has been a whirlwind, and already we have many new results," said Dr. Dennis Matson, Cassini project scientist at NASA's Jet Propulsion Laboratory, Pasadena, Calif. Weak, linear density waves caused in...

JPL -- Colorful new images from the Cassini spacecraft show that Saturn's northern hemisphere has a case of the blues. In the first image, the icy moon Mimas is set against a dazzling and dramatic portrait of Saturn's azure northern hemisphere and the shadows of its rings. A second image shows Saturn's northern polar region is a dim blue. The blue color of Saturn's northern latitudes may to be linked to the apparently cloud-free nature of the upper atmosphere there. A precise understanding...

JPL -- In a splendid portrait created by light and gravity, Saturn's lonely moon Mimas is seen against the cool, blue-streaked backdrop of Saturn's northern hemisphere. Delicate shadows cast by the rings arc gracefully across the planet, fading into darkness on Saturn's night side. The part of the atmosphere seen here appears darker and more bluish than the warm brown and gold hues seen in Cassini images of the southern hemisphere, due to preferential scattering of blue wavelengths by the...

Saturn's moon Mimas -- Mimas is a moon of Saturn that was discovered in 1789 by William Herschel. Mimas' low density (1.17) indicates that it is composed mostly of water ice with only a small amount of rock. Mimas' most distinctive feature is a colossal impact crater 130 km across, named Herschel after the moon's discoverer. Herschel covers almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor measure 10 km deep, and its central peak...
