Lee Rannals for redOrbit.com — Your Universe Online NASA announced on Monday its Cassini spacecraft has helped to discover a "video gamers' paradise" at Saturn. The space agency said scientists have spotted a second feature shaped like the 1980s video game icon Pac Man in the Saturn system on the moon Tethys. The pattern found appears in the thermal data obtained by Cassini composite infrared spectrometer. "Finding a second Pac-Man in the Saturn system tells us that the...

Cassini Spots Tiny Moon Methone
2012-05-22 04:03:14

NASA's Cassini spacecraft made its closest approach to Saturn's tiny moon Methone as part of a trajectory that will take it on a close flyby of another of Saturn's moons, Titan. The Titan flyby will put the spacecraft in an orbit around Saturn that is inclined, or tilted, relative to the plane of the planet's equator. The flyby of Methone took place on May 20 at a distance of about 1,200 miles (1,900 kilometers). It was Cassini's closest flyby of the 2-mile-wide (3-kilometer-wide) moon. The...

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"...

Over the past decade, the undersea robots known as autonomous underwater vehicles (AUVs) have become increasingly important in oceanographic research. Today's AUVs fall into two groups: 1) propeller-driven vehicles that can travel fast and carry lots of instruments, but are limited to expeditions of only a few days; and 2) "gliders," which can stay at sea for weeks or even months at a time, but cannot travel very quickly. MBARI engineers recently demonstrated a new super-efficient AUV that...

Scientists using data from NASA's Cassini spacecraft have learned that distinctive, colorful bands and splotches embellish the surfaces of Saturn's inner, mid-size moons. The reddish and bluish hues on the icy surfaces of Mimas, Enceladus, Tethys, Dione and Rhea appear to be the aftermath of bombardments large and small. A paper based on the findings was recently published online in the journal Icarus. In it, scientists describe prominent global patterns that trace the trade routes for...

NASA's Cassini spacecraft has returned Saturnian moon images from its flyby late last week, revealing light and dark contrasts worthy of chiaroscuro painters like Caravaggio. The flyby on August 13 targeted the geyser moon Enceladus, but also brought Cassini close to two other moons--Tethys and Dione. The raw images include the best ones to date of Penelope crater on the icy moon Tethys . Penelope crater, which is 150 kilometers (90 miles) wide, is the second-largest crater on Tethys. Cassini...

NASA says its Cassini spacecraft's magnetospheric imaging instrument has detected a new, temporary radiation belt around the orbit of one of Saturn's moons. Scientists located the new radiation belt in the orbit of the moon Dione, about 234,000 miles from the center of the planet. The new belt, which has been named the Dione belt, was detected by the instrument for only a few weeks on three separate occasions in 2005, the space agency said in a statement. Scientists believe that newly formed...

Scientists using the Cassini spacecraft's  Magnetospheric Imaging instrument (MIMI) have detected a new, temporary radiation belt  at Saturn, located around the orbit of its moon Dione at about 377 000 km from the center of the planet. The discovery will be presented at the European Planetary Science Congress in Potsdam by Dr Elias Roussos on Monday September 14. Radiation belts, like Earth's Van Allen belts, have been discovered at Jupiter, Saturn, Uranus and Neptune. ...

Something is about to happen on Saturn that's so pretty, even Hubble will pause to take a look. "On Feb. 24th, there's going to be a quadruple transit of Saturn's moons," says Keith Noll of the Hubble Space Telescope Science Institute. "Titan, Mimas, Dione and Enceladus will pass directly in front of Saturn and we'll see their silhouettes crossing Saturn's cloudtops"”all four at the same time." Hubble won't be the only one looking. Amateur astronomers will be able to see it, too. The...

Saturn's moon Calypso -- Calypso is a moon of Saturn discovered by Pascu, Seidelmann, Baum and Currie in 1980 from ground-based observations. Calypso is co-orbital with the moon Tethys, and resides in Tethys' trailing Lagrangian point (L5). The moon Telesto resides in Tethys' leading Lagrangian point. ----- Orbital radius: 294,660 km Diameter: 26 km (34 x 22 x 22) Mass: Unknown Orbital period: 1.8878 days Orbital inclination: 0 ----- NASA Learn more on this...

Telesto (Saturn Moon)

Telesto is a small Trojan moon of the sixth planet from the sun, Saturn. Telesto, which was discovered in 1980 by Smith, Reitsema, Larson and Fountain, is one of around 200 natural satellites in Saturnian orbit. It is one of only 62 moons that have a secure orbit, and only one of 53 named moons orbiting the ringed planet. Telesto was officially designated S/1980 S 13 and was officially named in 1983 after the Greek sea goddess of the same name. This moon is also designated as Saturn XIII...

Saturn's moon Tethys -- Tethys is a moon of Saturn that was discovered by Giovanni Cassini in 1684. Tethys is an icy body similar in nature to Dione and Rhea. The density of Tethys is 1.21 g/cm3, indicating that it is composed almost entirely of water-ice. Tethys's surface is heavily cratered and contains numerous cracks caused by faults in the ice. There are two different types of terrain found on Tethys, one composed of densely cratered regions and the other consisting of a dark...

Saturn's moon Mimas -- Mimas is a moon of Saturn that was discovered in 1789 by William Herschel. Mimas' low density (1.17) indicates that it is composed mostly of water ice with only a small amount of rock. Mimas' most distinctive feature is a colossal impact crater 130 km across, named Herschel after the moon's discoverer. Herschel covers almost 1/3 of the diameter of the entire moon; its walls are approximately 5 km high, parts of its floor measure 10 km deep, and its central peak...
