Cassini To Probe Enceladus Gravity, Take Pictures
2012-05-02 04:03:26

NASA's Cassini spacecraft will be flying within about 46 miles (74 kilometers) of Saturn's moon Enceladus on Wednesday, May 2, aiming primarily to learn more about the moon's internal structure. The flyby is the third part of a trilogy of flybys -- the other two took place on April 28, 2010, and Nov. 30, 2010 -- for Cassini's radio science experiment. The radio science team is particularly interested in learning how mass is distributed under Enceladus' south polar region, which features jets...

Image 1 - Saturn Moon Has Planet-Like Properties, NASA Finds
2012-04-27 08:07:32

Phoebe, one of Saturn´s 60+ moons, has been found to have planet-like properties, NASA scientists discovered while analyzing swarms of data collected and transmitted by the Cassini orbiter. New analysis of images of Phoebe lead scientists to theorize how the 140-mile-in-diameter rock started life. They suggest that it began its life as a planetoid in the Kuiper belt, a much larger version of the asteroid belt that sits on the outer edge of our planetary system. The scientists...

Image 1 - Cassini Eyes Blazing Trails In Saturn’s F-ring
2012-04-25 03:30:19

Brett Smith for Redorbit.com [ Watch the Video ] Scientists studying images from NASA´s Cassini spacecraft have found evidence of massive snowballs dragging glittering trails from one of Saturn´s rings. Saturn´s F ring has often been thought to be the most affected of the giant plant´s rings, often changing its look over the course of hours. The orbiting debris field measures a few hundred miles wide and is shepherded around the planet by two moons,...

Image 1 - Lake On Titan Resembles One In Africa
2012-04-21 05:09:53

A new study based on data from the Cassini spacecraft suggests that a lake on one of Saturn's moons behaves similarly to the Etosha salt pan on Earth. A group led by Thomas Cornet of the Université de Nantes, France, a Cassini associate, found characteristics of Ontario Lake on Titan are similar to Etosha Pan in Namibia, Africa because it drains and refills from below. Etosha Pan is a lake bed that fills with a shallow layer of water from groundwater levels that rise during...

Image 1 - Cassini Snaps Images As It Flies Over Enceladus
2012-04-17 03:36:15

These raw, unprocessed images of Saturn's moons Enceladus and Tethys were taken on April 14, 2012, by NASA's Cassini spacecraft. Cassini flew by Enceladus at an altitude of about 46 miles (74 kilometers). This flyby was designed primarily for the ion and neutral mass spectrometer to analyze, or "taste," the composition of the moon's south polar plume as the spacecraft flew through it.  Cassini's path took it along the length of Baghdad Sulcus, one of Enceladus' "tiger stripe"...

The Cassini spacecraft has captured new images and measurements of some of Saturn´s moons. This new evidence may help scientists determine if life does exist outside of Earth´s closed system. Enceladus, the moon with the most promise for microbial life, has cryovolcanic geysers on its surface that spews into the moons thin atmosphere. The Cassini spacecraft flew into these plumes at an altitude of 46 miles above the surface. They used the ion and neutral mass spectrometer...

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...

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 Hyperion
2004-10-19 04:45:41

Saturn's moon Hyperion -- Hyperion is a moon of Saturn discovered by Bond and Lassell in 1848. It is the largest highly irregular (non-spherical) body in the solar system (Proteus is quite a bit larger but is almost spherical). It seems likely that Hyperion is a fragment of a larger body that was broken by a large impact in the distant past. The largest crater on its surface is approximately 120 kilometers in diameter and 10 kilometers deep. Like most of Saturn's moons, Hyperion's low...

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...
