WASHINGTON, June 22, 2011 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft has discovered the best evidence yet for a large-scale saltwater reservoir beneath the icy crust of Saturn's moon Enceladus. The data came from the spacecraft's direct analysis of salt-rich ice grains close to the jets ejected from the moon.

NASA's Cassini spacecraft has successfully completed its second-closest encounter with Saturn's icy moon Helene, beaming down raw images of the small moon. At closest approach, on June 18, Cassini flew within 4,330 miles (6,968 kilometers) of Helene's surface. It was the second closest approach to Helene of the entire mission. Cassini passed from Helene's night side to the moon's sunlit side. It also captured images of the Saturn-facing side of the moon in sunlight, a region that was only...

NASA said on Wednesday that an instrument aboard its Cassini spacecraft is temporarily out of service. It said the plasma spectrometer aboard the spacecraft studying Saturn was turned off this week as a precaution after a short circuit. This instrument is used to measure the energy of electrons and protons. Engineers are troubleshooting the problem, but it is unclear when the instrument will be back online. NASA said Cassini will continue to collect other data while this instrument is...

WASHINGTON, May 19, 2011 /PRNewswire-USNewswire/ -- NASA's Cassini spacecraft and a European Southern Observatory ground-based telescope tracked the growth of a giant early-spring storm in Saturn's northern hemisphere so powerful it stretches around the entire planet. The rare storm has been wreaking havoc for months and shot plumes of gas high into the planet's atmosphere.

Have the surface and belly of Saturn's smog-shrouded moon, Titan, recently simmered like a chilly, bubbling cauldron with ice volcanoes, or has this distant moon gone cold? In a newly published analysis, a pair of NASA scientists analyzing data collected by the Cassini spacecraft suggest Titan may be much less geologically active than some scientists have thought. In the paper, published in the April 2011 edition of the journal Icarus, scientists conclude Titan's interior may be cool and...

Like a petulant adolescent, Saturn is sending out mixed signals. Recent data from NASA's Cassini spacecraft show that the variation in radio waves controlled by the planet's rotation is different in the northern and southern hemispheres. Moreover, the northern and southern rotational variations also appear to change with the Saturnian seasons, and the hemispheres have actually swapped rates. These two radio waves, converted to the human audio range, can be heard in a new video available...

This is the first time scientists have obtained current evidence of rain soaking Titan's surface at low latitudes. As spring continues to unfold on Saturn, April showers on the planet's largest moon, Titan, have brought methane rain to its equatorial deserts, as revealed in images captured by NASA's Cassini spacecraft. This is the first time scientists have obtained current evidence of rain soaking Titan's surface at low latitudes. The observations are released today in the journal Science....

Heat output from the south polar region of Saturn's moon Enceladus is much greater than was previously thought possible, according to a new analysis of data collected by NASA's Cassini spacecraft. The study was published in the Journal of Geophysical Research on March 4. Data from Cassini's composite infrared spectrometer of Enceladus' south polar terrain, which is marked by linear fissures, indicate that the internal heat-generated power is about 15.8 gigawatts, approximately 2.6 times the...

NASA announced Tuesday that the Cassini spacecraft passed by and snapped images of several of Saturn's moons. The space agency said the Cassini spacecraft passed within 37,282 miles of Enceladus and 17,398 miles of Helene.  The spacecraft also shot an image of Mimas in front of Saturn's rings. NASA said that one of Cassini's images is looking at the famous jets erupting from the south polar terrain of Enceladus. The Cassini-Huygens mission is a cooperative project of NASA, the...

Raw images obtained by NASA's Cassini spacecraft from the closest flyby of Saturn's moon Rhea have begun streaming to Cassini's raw image page. At closest approach, Cassini glided within about 69 kilometers (43 miles) of Rhea's surface at 4:53 AM UTC on Jan. 11, which was 10:53 PM Pacific Time on Jan. 10. To see the raw images, go to http://saturn.jpl.nasa.gov/photos/raw/ and click on "Search Images." --- Image Caption: NASA's Cassini spacecraft captured this raw image of Saturn's icy moon...

Saturn's moon Phoebe -- Phoebe is the outermost of Saturn's known moons. Phoebe is almost 4 times more distant from Saturn than its nearest neighbor (Iapetus). It was discovered by William Henry Pickering in 1898. Most of Saturn's moons have very bright surfaces, but Phoebe's albedo is very low (.06), as dark as lampblack. All of Saturn's moons except for Phoebe and Iapetus orbit very nearly in the plane of Saturn's equator. Phoebe's orbit is retrograde, inclined almost 175, and is...
