Image 1 - Enceladus Has Snow Flurries And Perfect Powder For Skiing
2011-10-03 09:14:47

Global and high resolution mapping of Enceladus confirms that the weather forecast for Saturn's unique icy moon is set for ongoing snow flurries.  The superfine ice crystals that coat Enceladus's surface would make perfect powder for skiing, according to Dr Paul Schenk of the Lunar and Planetary Institute (Houston, Texas), who will present the results at the EPSC-DPS Joint Meeting 2011 in Nantes, France on Monday 3rd October. Mapping of global color patterns and measurements of...

Enceladus Influences Saturn's Chemical Composition

   Chalk up one more feat for Saturn's intriguing moon Enceladus. The small, dynamic moon spews out dramatic plumes of water vapor and ice -- first seen by NASA's Cassini spacecraft in 2005. It possesses simple organic particles and may house liquid water beneath its surface. Its geyser-like jets create a gigantic halo of ice, dust and gas around Enceladus that helps feed Saturn's E ring. Now, thanks again to those icy jets, Enceladus is the only moon in our solar system known to...

  As early as Sept. 8th, NASA's GRAIL mission will blast off to uncover some of the mysteries beneath the surface of the Moon. That cratered gray exterior hides some tantalizing things — even, perhaps, a long-lost companion. If a paper published recently in the journal Nature* is right, two moons once graced our night skies. The proposition has not been proven, but has drawn widespread attention. "It's an intriguing idea," says David Smith, GRAIL's deputy principal...

  NASA's Cassini spacecraft captured new views of Saturn's oddly shaped moon Hyperion during its encounter with this cratered body on Thursday, Aug. 25. Raw images were acquired as the spacecraft flew past the moon at a distance of about 15,500 miles (25,000 kilometers), making this the second closest encounter. Hyperion is a small moon -- just 168 miles (270 kilometers) across. It has an irregular shape and surface appearance, and it rotates chaotically as it tumbles along in...

ESA's Herschel space observatory has shown that water expelled from the moon Enceladus forms a giant torus of water vapor around Saturn. The discovery solves a 14-year mystery by identifying the source of the water in Saturn's upper atmosphere. Herschel's latest results mean that Enceladus is the only moon in the Solar System known to influence the chemical composition of its parent planet. Enceladus expels around 250 kg of water vapor every second, through a collection of jets from the south...

WASHINGTON, July 6, 2011 /PRNewswire-USNewswire/ -- Scientists analyzing data from NASA's Cassini spacecraft now have the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears at approximately 35 degrees north latitude on Saturn. Pictures from Cassini's imaging cameras show the storm wrapping...

NASA reported today that scientists analyzing data from its Cassini spacecraft have discovered close-up details of a Saturn storm that is eight times the surface area of Earth. The Cassini spacecraft located the storm about 35 degrees north latitude on Saturn on December 5, 2010. Cassini's imaging cameras show the storm wrapping around the entire planet covering about 2 billion square miles. NASA said the storm is about 500 times larger than the biggest storm previously seen by Cassini...

Scientists say they have found convincing evidence that Saturn's moon Enceladus has a large-scale subterranean saltwater ocean. The discovery was made using data collected during the Cassini-Huygens mission to Saturn. The plumes of shooting water vapor and tiny grains of ice into space were originally discovered emanating from Enceladus by the Cassini spacecraft in 2005. The researchers from the University of Heidelberg and University of Colorado said during three of Cassini's passes...

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. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Data from Cassini's cosmic dust analyzer show the grains expelled from fissures, known as tiger stripes, are...

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...

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:
