Cassini Mission's Final Plans Laid Out
2012-03-26 12:09:00

The Cassini space probe will be diving into a gap between Saturn's atmosphere and its innermost ring for the final part of its mission in 2016. Linda Spilker, the mission's project scientist, outlined the details of the spacecraft's final leg recently at the 43rd Lunar and Planetary Science Conference (LPSC) in the Woodlands, Texas. Cassini's last set of orbits may bring scientists a new perspective, and help unlock more clues about Saturn's rings. The spacecraft will carry out about...

2012-03-23 03:54:01

The Smithsonian's National Air and Space Museum has bestowed its highest group honor, the Trophy for Current Achievement, on NASA's Cassini mission to Saturn. The annual award recognizes outstanding achievements in the fields of aerospace science and technology. The trophy was presented Wednesday during an evening ceremony at the museum in Washington. Established in 1985, the award has been presented to seven NASA planetary mission teams. "This joint mission has produced an...

Cassini Sees Saturn Stressing Out Enceladus
2012-03-20 03:15:13

Images from NASA's Cassini spacecraft have, for the first time, enabled scientists to correlate the spraying of jets of water vapor from fissures on Saturn's moon Enceladus with the way Saturn's gravity stretches and stresses the fissures. The result is among the Cassini findings presented today at the Lunar and Planetary Science Conference at The Woodlands, Texas. "This new work gives scientists insight into the mechanics of these picturesque jets at Enceladus and shows that Saturn really...

This raw, unprocessed image of Saturn's second largest moon, Rhea, was taken on March 10, 2012, by NASA's Cassini spacecraft. This was a relatively distant flyby with a close-approach distance of 26,000 miles (42,000 kilometers), well suited for global geologic mapping. During the flyby, Cassini captured distinctive views of the moon's cratered surface, creating a 30-frame mosaic of Rhea's leading hemisphere and the side of the moon that faces away from Saturn. The observations included...

Cassini Detects Oxygen On Saturn's Moon Dione
2012-03-02 13:18:55

Researchers report this week in the journal Geophysical Research Letters that NASA's Cassini spacecraft has detected oxygen on one of Saturn's moons. They said their finding increases the likelihood of finding the ingredients for life on one of the moons orbiting gas giants. The ice moon, Dione, has no liquid water and does not have the proper conditions to support life, Andrew Coates of the University College London said.  However, he said that it is possible that other moons of...

Image 1 - Titan Is A Moon Of Many Moods
2012-02-24 04:40:42

A set of recent papers, many of which draw on data from NASA's Cassini spacecraft, reveal new details in the emerging picture of how Saturn's moon Titan shifts with the seasons and even throughout the day. The papers, published in the journal Planetary and Space Science in a special issue titled "Titan through Time", show how this largest moon of Saturn is a cousin - though a very peculiar cousin - of Earth. "As a whole, these papers give us some new pieces in the jigsaw puzzle that is...

The Many Faces Of Titan's Dunes
2012-01-23 10:34:54

A new analysis of radar data from NASA's Cassini mission, in partnership with the European Space Agency and the Italian Space Agency, has revealed regional variations among sand dunes on Saturn's moon Titan. The result gives new clues about the moon's climatic and geological history. Dune fields are the second most dominant landform on Titan, after the seemingly uniform plains, so they offer a large-scale insight into the moon's peculiar environment. The dunes cover about 13 percent of the...

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:
