Europa's Churn Leads To Oxygen BurnMoffett Field CA (SPX) Jun 01, 2010 There may be enough oxygen in the waters of Jupiter's moon Europa to support millions of tons worth of fish, according to a new study. While no one is suggesting there are fish on Europa, this finding suggests the Jovian satellite could be capable of supporting the kinds of life familiar to us here on Earth. Europa, which is roughly the size of Earth's moon, is enveloped by a global ocean about 100 miles deep (160 km), with an icy crust that may be only a few miles thick. From what we know of Eart ... read more |

Cassini Returning Enceladus Gravity Data
Pasadena CA (JPL) May 03, 2010NASA's Cassini spacecraft successfully completed its 26-hour gravity observation at Saturn's moon Enceladus this week, sending back data scientists will use to understand the moon's interior composition and structure. The flyby took Cassini through the water-rich plume flaring out from Enceladus' south polar region, with a closest approach of about 100 kilometers (60 miles) occurring in th ... more LRO Team Helps Track Laser Signals To Russian Rover Mirror
Greenbelt MD (SPX) Apr 27, 2010Using information provided by NASA's Lunar Reconnaissance Orbiter (LRO) instrument teams, researchers at the University of California San Diego have successfully pinpointed the location of a long lost light reflector left on the lunar surface by bouncing laser signals from Earth to the Russian Lunokhod 1 retroreflector. The initial imaging of the two Russian rovers, Lunokhod 1 and 2 were m ... more Cassini Measures Tug Of Enceladus
Pasadena CA (JPL) Apr 27, 2010NASA's Cassini spacecraft will be gliding low over Saturn's moon Enceladus for a gravity experiment designed to probe the moon's interior composition. The flyby, which will take Cassini through the water-rich plume flaring out from Enceladus's south polar region, will occur on April 27 Pacific time and April 28 UTC. At closest approach, Cassini will be flying about 100 kilometers (60 miles ... more |

Counting The Craters Of TitanMoffett Field CA (SPX) Apr 23, 2010 A new study in the journal Icarus provides the latest round-up of the number of impact craters found on Saturn's moon Titan. Between 2004 and December 2007, Cassini had surveyed 22 percent of Titan's surface. Scientists analyzed images taken by the spacecraft's high-resolution Radar Mapper instrument, and found 49 impact craters. "Impact craters are created on every planet because of asteroids, comets and other debris that collide with their surfaces," said Charles Wood, senior scientist at ... read more |
