Latest Mimas Stories
Cassini scientists may have identified the source of one of Saturn's more mysterious rings. Saturn's G ring likely is produced by relatively large, icy particles that reside within a bright arc on the ring's inner edge.
NASA Cassini spacecraft images of Saturn's diaphanous G and E rings are yielding new clues about their structure and formation.
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.
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.
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.
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. The new findings include refinements in the orbits of several of Saturn's small satellites.
Colorful new images from the Cassini spacecraft show that Saturn's northern hemisphere has a case of the blues.
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.
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...
