The Cassini mission, a joint venture of NASA and the European and Italian space agencies has been orbiting Saturn for five Earth years as of Tuesday. NASA officials said that is about one sixth of a Saturnian year -- enough time for the spacecraft to have observed seasonal changes on the planet, its moons and sunlight's angle on the dramatic rings. Cassini passed through a gap in the rings as it entered orbit on June 30, 2004, NASA said. It finished its prime mission in 2008 and continues to...

PASADENA, Calif., June 24 /PRNewswire-USNewswire/ -- For the first time, scientists working on NASA's Cassini mission have detected sodium salts in ice grains of Saturn's outermost ring. Detecting salty ice indicates that Saturn's moon Enceladus, which primarily replenishes the ring with material from discharging jets, could harbor a reservoir of liquid water -- perhaps an ocean -- beneath its surface. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO ) Cassini discovered the...

Researchers in Europe released a new report on Wednesday that suggests the geyser seen on the surface of Saturn's moon Enceladus could be fed by a salty ocean underneath the surface. Writing in the journal Nature, scientists said that the discovery could support theories of the existence of extraterrestrial life. Scientists first discovered Enceladus' habit of spewing a mix of water vapor, gas and tiny grains of ice into space in 2005 with observations from the Cassini spacecraft. Enceladus...

The 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 frigid bodies that inhabit the cold, outer reaches of our solar system. The goal is to study up-close the...

Cloud chasers studying Saturn's moon Titan say its clouds form and move much like those on Earth, but in a much slower, more lingering fashion. Their forecast for Titan's early autumn -- warm and wetter. Scientists with NASA's Cassini mission have monitored Titan's atmosphere for three-and-a-half years, between July 2004 and December 2007, and observed more than 200 clouds. They found that the way these clouds are distributed around Titan matches scientists' global circulation models. The...

Scientists believe that ice volcanoes observed on Saturn's moon Enceladus may stem from a sea beneath its surface, which could support theories for the existence of extraplanetary life. Since the Cassini spacecraft arrived on Saturn four years ago, scientists have been trying to determine what is causing Enceladus' volcanoes to spew ice. "What we have seen over the course of our travels has informed, moved and amazed us," planetary scientist Carolyn Porco, who heads Cassini's imaging team,...

A team of planetary scientists working on the NASA/ESA/ASI Cassini-Huygens mission has discovered tiny, charged icy particles in the plume from Saturn's moon Enceladus that offer a tantalizing glimpse of the interior of this enigmatic world. Dr Geraint Jones and Dr Chris Arridge, both from University College London's Mullard Space Science Laboratory, will present the results on behalf of the Cassini Plasma Spectrometer (CAPS) instrument team on Wednesday 22nd April at the European Week of...

Saturn's largest moon, Titan, may have a subterranean ocean of hydrocarbons and some topsy-turvy topography in which the summits of its mountains lie lower than its average surface elevation, according to new research. Titan is also more squashed in its overall shape"”like a rubber ball pressed down by a foot"”than researchers had expected, said Howard Zebker, a Stanford geophysicist and electrical engineer involved in the work. The new findings may help explain the presence of...

Astronomers have theorized that the unexplained terrain on one of Saturn's icy moons might have happened when the moon went from a relatively fast-spinning body to one spinning more slowly, BBC News reported. The bulging ridge of Iapetus, which encircles the moon's equator and reaches an altitude of over 12 miles in certain areas, was discussed in detail during a presentation at the Lunar and Planetary Science Conference in Texas. James Roberts and colleagues at the Johns Hopkins University...

The U.S. space agency's Cassini spacecraft has produced new movies and images of Saturn's moon Titan, providing new glimpses of its Earth-like landscapes. The National Aeronautics and Space Administration said the new flyover topographic maps were made from stereo pairs of radar images by Cassini radar team member Randy Kirk of the Astrogeology Science Center at the U.S. Geological Survey. NASA said Kirk used some of the 20 or so areas where two or more overlapping radar measurements were...

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

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...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...

Saturn's moon Rhea -- Rhea is the second largest moon of Saturn. It was discovered in 1672 by Giovanni Cassini. Rhea is an icy body with a density of about 1.24 gm/cm3. This low density indicates that it has a rocky core taking up less than one-third of the moon's mass with the rest composed of water-ice. Rhea's features resemble those of Dione, with dissimilar leading and trailing hemispheres, suggesting similar composition and histories. The temperature on Rhea is -174°C in direct...

Saturn's moon Helene -- Helene is a moon of Saturn, discovered by Laques and Lecacheux in 1980 from ground-based observations. It is co-oribtal with Dione and located in its leading Lagrangian point (L4) and hence is sometimes referred to as "Dione B". ----- Orbital radius: 377,400 km Diameter: 33 km (36 x 32 x 30) Mass: Unknown Orbital period: 2.7369 days Orbital inclination: 0.2 ----- NASA Learn more on this topic from eLibrary here:
