Cassini Hints At Ocean Within Saturn's Moon Enceladus Pasadena CA (SPX) Jun 26, 2009 
European scientists on the joint NASA/ESA Cassini mission have detected, for the first time, sodium salts in ice grains of Saturn's E-ring, which is primarily replenished by material from the plumes of water vapour and ice grains emitted by Saturn's moon Enceladus. The detection of salty ice indicates that the little moon harbours a reservoir of liquid water, perhaps even an ocean, beneath ... read moreExotic Life Could Sprout From Chemistry On Titan 
Moffett Field CA (SPX) Jun 26, 2009If life exists on Titan, it's anyone's guess what that life looks like. Saturn's largest moon is not a good candidate for Earth-like life because it usually lacks liquid water on the surface. But one of Titan's most promising features is the presence of lakes filled with liquid hydrocarbons, or molecules made of hydrogen and carbon, such as methane and ethane. These lakes were recently ... more

Salty Ocean In The Depths Of Enceladus
Potsdam, Germany (SPX) Jun 25, 2009An enormous plume of water spurts in giant jets from the south pole of Saturn's moon Enceladus. In a report published in the international science journal Nature, European researchers provide evidence that this magnificent plume is fed by a salty ocean. The discovery could have implications for the search for extraterrestrial life as well as our understanding of how planetary moons are for ... more Jets On Enceladus Not Geysers From Underground Ocean 
Boulder CO (SPX) Jun 25, 2009Water vapor jets that spew from the surface of Saturn's icy moon Enceladus are not really geysers from an underground ocean as initially envisioned by planetary scientists, according to a study led by the University of Colorado at Boulder. First observed following a close flyby by NASA's Cassini spacecraft in July 2005, the jets were found to consist of both water vapor and icy particles ... more Never-Before-Seen Images From Saturn 
Pasadena CA (SPX) Jun 23, 2009In anticipation of the upcoming equinox at Saturn, the imaging science team on NASA's Cassini spacecraft is releasing a series of images and movies capturing scenes possible only once every 15 years. This bounty of sights, that includes time-lapse sequences in which Saturnian moons eclipse each other and cast long shadows onto the planet's famous rings, represents only some of the fruits ... more Shaken And Stirred: Lab Studies Ice From Frigid Worlds
Pasadena CA (SPX) Jun 15, 2009The most exotic frozen cocktails on Earth won't be found in a chic restaurant or trendy bar. Scientists are mixing up these icy concoctions in a rather nondescript laboratory not much bigger than a janitor's closet. The surroundings are spartan, but the recipes they're using are out of this world. Researchers in JPL's Ice Physical Properties Laboratory are recreating the ices found on the ... more |

Dancing Moon Shadows On Saturn's Rings
Pasadena CA (SPX) Mar 24, 2009In a sure sign that Saturn is approaching that special time - called equinox - during its travels around the sun, images taken by the cameras of NASA's Cassini spacecraft have captured, for the first time, the shadows of the planet's moons cast onto its broad expanse of rings. Like Earth and most of the other planets, Saturn's spin axis is tilted relative to its motion around the sun. This ... more Quadruple Saturn Moon Transit Snapped By Hubble 
Baltimore, MD (SPX) Mar 19, 2009On February 24, 2009, the Hubble Space Telescope took a photo of four moons of Saturn passing in front of their parent planet. In this view, the giant orange moon Titan casts a large shadow onto Saturn's north polar hood. Below Titan, near the ring plane and to the left is the moon Mimas, casting a much smaller shadow onto Saturn's equatorial cloud tops. Farther to the left, and off Saturn ... more Cassini Swaps Thrusters 
Pasadena CA (SPX) Mar 13, 2009Early this morning the Cassini spacecraft relayed information that it had successfully swapped to a backup set of propulsion thrusters late Wednesday. The swap was performed because of degradation in the performance of the primary thrusters, which had been in use since Cassini's launch in 1997. This is only the second time in Cassini's 11 years of flight that the engineering teams have gon ... more Cassini switches to backup thrusters 
Pasadena, Calif. (UPI) Mar 12, 2009 U.S. space agency scientists say the Cassini spacecraft has successfully switched to a backup set of propulsion thrusters as it orbits Saturn. NASA said the late Wednesday swap was performed because of degradation in the performance of the primary thrusters, which had been in use since Cassini's launch in 1997. The space agency said ... more |
