NASA's Cassini spacecraft is going to get another up-close-and-personal look at Saturn's moon Enceladus on Monday. Scientists hope the glimpse at fractures on the icy moon's surface will provide clues as to how the jets spewing from them form. The spacecraft will zoom past the tiny moon just 30 miles (50 kilometers) over the surface. Immediately after closest approach, Cassini will train its cameras onto the fissures that run along Enceladus' south pole. Jets of icy...

Shorty after 9:03 p.m. Pacific Time, the Cassini spacecraft began sending data to Earth following a close flyby of Saturn's moon Enceladus. During closest approach, Cassini successfully passed only 50 kilometers (30 miles) from the surface of the tiny moon. Cassini's signal was picked up by the Deep Space Network station in Canberra, Australia, and relayed to the Cassini mission control at NASA's Jet Propulsion Laboratory in Pasadena, Calif. "We are happy to report that Cassini's begun...

Fractures, or "tiger stripes," where icy jets erupt on Saturn's moon Enceladus will be the target of a close flyby by the Cassini spacecraft on Monday, Aug. 11. Cassini will zoom past the tiny moon a mere 50 kilometers (30 miles) from the surface. Just after closest approach, all of the spacecraft's cameras -- covering infrared wavelengths, where temperatures are mapped, as well as visible light and ultraviolet -- will focus on the fissures running along the moon's south pole. That is where...

By Philip Haldiman, The Arizona Daily Star, Tucson Jul. 31--Our planet isn't the only heavenly body with liquid on its surface. Scientists from the University of Arizona and NASA on Wednesday announced at least one of the large, lakelike features on a moon of Saturn is wet. The moon, Titan, contains liquid hydrocarbons and ethane, scientists said. Besides Earth, this makes Titan the only known body in our solar system with liquid on its surface, NASA said in a press release. The...

Four students have won the Cassini Scientist for a Day contest, with most choosing Rhea, Saturn's second-largest moon, as the best place for scientists to study using NASA's Cassini spacecraft.Contest participants had to choose one of three target areas for Cassini's camera: Saturn's moon Enceladus, Rhea, or a section of Saturn's rings that includes the tiny moon Pan. The students had to write an essay explaining why their chosen snapshot would yield the most scientific rewards, and the...

A team of scientists led from the UK has discovered that the rapid changes in Saturn's F ring can be attributed to small moonlets causing perturbations. Their results are reported in Nature (5th June 2008). Saturn's F ring has long been of interest to scientists as its features change on timescales from hours to years and it is probably the only location in the solar system where large scale collisions happen on a daily basis. Understanding these processes helps scientists understand the...

Two decades of scrutinizing Saturn are finally paying off, as scientists have discovered a wave pattern, or oscillation, in Saturn's atmosphere only visible from Earth every 15 years. The discovery of the wave pattern is the result of a 22-year campaign observing Saturn from Earth (the longest study of temperature outside Earth ever recorded), and the Cassini spacecraft's observations of temperature changes in the giant planet's atmosphere over time. The Cassini infrared results, which...

A monster storm spawning bolts of lightning 10,000 times more powerful than any seen on Earth is raging on the ringed planet Saturn. The powerful electrical storm cropped up in Saturn's southern hemisphere five months ago, when it was first spotted by NASA's Cassini spacecraft, and has persevered to become the planet's longest continuously recorded tempest to date. "We saw similar storms in 2004 and 2006 that each lasted for nearly a month, but this storm is longer-lived by...

PASADENA, Calif. "“ As a powerful electrical storm rages on Saturn with lightning bolts 10,000 times more powerful than those found on Earth, the Cassini spacecraft continues its five-month watch over the dramatic events. Scientists with NASA's Cassini-Huygens mission have been tracking the visibly bright, lightning-generating storm--the longest continually observed electrical storm ever monitored by Cassini. Saturn's electrical storms resemble terrestrial thunderstorms, but on a much...

NEW YORK — Stunning images of Saturn and its moons will bring the ringed planet down to Earth for visitors at the American Museum of Natural History here starting Saturday. The new exhibition "Saturn: Images from the Cassini-Huygens Mission" offers just a sample of the more than 140,000 images beamed back to Earth across half a billion miles by NASA's Cassini spacecraft. Launched by NASA in 1997, Cassini became the first spacecraft to orbit Saturn in 2004. The international...

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:
