Is That Titan Or Utah Pasadena CA (JPL) Mar 08, 2010 
Planetary scientists have been puzzling for years over the honeycomb patterns and flat valleys with squiggly edges evident in radar images of Saturn's moon Titan. Now, working with a "volunteer researcher" who has put his own spin on data from NASA's Cassini spacecraft, they have found some recognizable analogies to a type of spectacular terrain on Earth known as karst topography. At a poster se ... read moreZooming In On Heat At Baghdad Sulcus 
Pasadena CA (JPL) Feb 24, 2010The right-hand image shows a dramatically improved view of heat radiation from a warm fissure near the south pole of Saturn's icy moon Enceladus. It was obtained by NASA's Cassini spacecraft during its Nov. 21, 2009, flyby of that moon. The fissure, named Baghdad Sulcus, is one of four so-called "tiger stripe" features that emit jets of water vapor and ice particles. The tiger stripe runs ... more

Behold The Violent History Of Saturn's White Whale Moon
Pasadena CA (JPL) Feb 22, 2010Like the battered white whale Moby Dick taunting Captain Ahab, Saturn's moon Prometheus surges toward the viewer in a 3-D image from NASA's Cassini spacecraft. The image exposes the irregular shape and circular surface scars on Prometheus, pointing to a violent history. These craters are probably the remnants from impacts long ago. Prometheus is one of Saturn's innermost moons. It or ... more Cassini Shoots New Close-Ups Of Death Star-Like Moon 
Pasadena CA (JPL) Feb 18, 2010Blazing through its closest pass of the Saturnian moon Mimas on Feb. 13, Cassini sent back striking close-ups of the moon likened to the Death Star from "Star Wars" and the enormous crater scarring its surface. The flyby also yielded solid data on the moon's thermal signature and surface composition. Some of the raw, unprocessed images sent back from the flyby show the bright, steep slopes ... more Cassini Set To Do Retinal Scan Of Saturnian Eyeball 
Pasadena CA (JPL) Feb 17, 2010On Feb. 13, 2010, NASA's Cassini spacecraft will make its closest examination yet of Mimas, an eyeball-shaped moon of Saturn that has also been likened to the Death Star of "Star Wars." The spacecraft will be returning the highest-resolution images yet of this battered satellite. Mimas bears the mark of a violent, giant impact from the past - the 140-kilometer-wide (88-mile-wide) Herschel ... more The Active Moons Of Saturn 
Washington DC (SPX) Feb 15, 2010Like midnight taggers, Saturn's moons Dione, Tethys, Mimas and Rhea may be spraying their unique signatures all over Saturn's environment when no one's looking. Or maybe not; they've never been caught in the act, unlike their sibling moon Enceladus, which has been repeatedly observed shooting a dramatic plume of ice vapor high above its surface. Other than Enceladus, there are just a few a ... more |

Studying Titan's Lakes On Earth
Moffett Field CA (SPX) Jan 29, 2010The recent discovery of lakes on Saturn's moon Titan make it the only other object in the solar system known to have liquid on its surface. However, dipping 179 degrees C (290 degrees F) below freezing, these lakes are definitely not filled with water. "The water is frozen so solid on Titan that you can liken it to silicate rocks on Earth," says Vincent Chevrier of the University of Arkans ... more Route 66: Cassini's Next Look At Titan 
Los Angeles CA (JPL) Jan 28, 2010Sixteen days after last visiting Saturn's largest moon, NASA's Cassini spacecraft returns for another look-see of the cloud-shrouded moon - this time from on high. The flyby on Thursday, Jan. 28, referred to as "T-66" in the hollowed halls of Cassini operations, will place the spacecraft within 7,490 kilometers (4,654 miles) above the surface during time of closest approach. While th ... more Cassini returns to Saturn's largest moon 
Pasadena, Calif. (UPI) Jan 27, 2009 NASA says its Cassini spacecraft will return to Saturn's largest moon, Titan, this week to again inspect the cloud-shrouded moon, but from 4,654 miles away. The Thursday flyby will place Cassini more than 3,970 miles higher above Titan's surface than it was during it's Jan. 12 flyby, but scientists say that will not make the new mission any less valuable. Instead, NASA said the h ... more Groovy Hills Rising From Titan Surface 
Pasadena CA (JPL) Jan 26, 2010Hills with a wrinkly radial pattern stand out in a new radar image captured by NASA's Cassini spacecraft on Dec. 28, 2009. The grooved mounds in the picture, which are located in a northern hemisphere region known as Belet, are about 80 kilometers (50 miles) wide and about 60 meters (200 feet) high. The shapes of these landscape features have not been seen on Titan before, though the ... more |
