Fractures, or "tiger stripes," where icy jets erupt on Saturn's moon Enceladus will be the target of a close flyby by the Cassini spacecraft on Monday, Aug. 11. Cassini will zoom past the tiny moon a mere 50 kilometers (30 miles) from the surface. Just after closest approach, all of the spacecraft's cameras -- covering infrared wavelengths, where temperatures are mapped, as well as visible light and ultraviolet -- will focus on the fissures running along the moon's south pole. That is where...

NEW YORK — Stunning images of Saturn and its moons will bring the ringed planet down to Earth for visitors at the American Museum of Natural History here starting Saturday. The new exhibition "Saturn: Images from the Cassini-Huygens Mission" offers just a sample of the more than 140,000 images beamed back to Earth across half a billion miles by NASA's Cassini spacecraft. Launched by NASA in 1997, Cassini became the first spacecraft to orbit Saturn in 2004. The international...

A selection of the best images from Saturn, its rings and moons will appear in an exhibition opening on April 26 at the American Museum of Natural History in New York City .The show, called "Saturn: Images from the Cassini-Huygens Mission," will run through March 29, 2009. It features dramatic, up-close-and-personal images in small individual views and super-large mosaics. Roughly 50 images taken by the Cassini-Huygens mission in visible light, infrared and radar have been hand-picked by a...

NASA will turn control of the Cassini spacecraft at Saturn over to students for a day in a contest aimed at boosting interest in science among today's youth. An essay contest for students in grades 5 through 12 will determine which of three science targets Cassini will photograph on June 10, the space agency announced late Thursday. Cassini scientists regularly debate exactly which images of Saturn's many moons and rings will produce the most science results, a task they are...

PASADENA, Calif. -- NASA's Cassini spacecraft tasted and sampled a surprising organic brew erupting in geyser-like fashion from Saturn's moon Enceladus during a close flyby on March 12. Scientists are amazed that this tiny moon is so active, "hot" and brimming with water vapor and organic chemicals. New heat maps of the surface show higher temperatures than previously known in the south polar region, with hot tracks running the length of giant fissures. Additionally, scientists say the...

NASA's Cassini spacecraft performed a daring flyby of Saturn's moon Enceladus on Wed., March 12, flying about 15 kilometers per second (32,000 mph) through icy water geyser-like jets. The spacecraft snatched up precious samples that might point to a water ocean or organics inside the little moon. Scientists believe the geysers could provide evidence that liquid water is trapped under the icy crust of Enceladus. The geysers emanate from fractures running along the moon's south pole, spewing...

NASA's Cassini spacecraft will make an unprecedented "in your face" flyby of Saturn's moon Enceladus on Wed., March 12. The spacecraft, orchestrating its closest approach to date, will skirt along the edges of huge Old-Faithful-like geysers erupting from giant fractures on the south pole of Enceladus. Cassini will sample scientifically valuable water-ice, dust and gas in the plume. The source of the geysers is of great interest to scientists who think liquid water, perhaps even an ocean, may...

Cosmic sprinklers that spurt misty jets from cracks along Saturn's sixth largest moon could hint at a vast watery lake hidden beneath the icy shell of Enceladus. In 2005, NASA's Cassini spacecraft revealed giant geysers of ice grains and water vapor shooting from the south pole of Enceladus. But how the geysers formed and the source of the ice crystals had remained a mystery until now. New research, detailed in the Feb. 7 issue of the journal Nature, provides a clear view of the...

One of Saturn's rings does housecleaning, soaking up material gushing from the fountains on Saturn's tiny ice moon Enceladus, according to new observations from the Cassini spacecraft. "Saturn's A-ring and Enceladus are separated by 100,000 kilometers (62,000 miles), yet there's a physical connection between the two," says William Farrell of NASA's Goddard Space Flight Center in Greenbelt, Md. "Prior to Cassini, it was believed that the two bodies were separate and distinct entities, but...

Celebrating the 10th anniversary of its launch from Cape Canaveral, the Cassini-Huygens mission to Saturn is once again at the center of scientific attention. Its latest discoveries about the ringed planet are a leading topic of conversation among the nearly 1,500 scientists gathered this week at a major astronomy conference in Orlando, Fla. Cassini rode into space Oct. 15, 1997, atop a U.S. Air Force Titan IVB. Its mission: to orbit and study the Saturnian system for four years and to put...
