Cassini Cruises By Rhea And HelenePasadena CA (JPL) Mar 15, 2010 Cassini's closest-ever flyby of Saturn's moon Rhea went quite smoothly and teams are busy checking out their data! These flybys never fail to amaze me. And the raw images - which give us an unprocessed first look - are really cool! Raw image N00152150 gives us a view of part of the bright, fractured terrain we refer to as "wispy terrain" from about 14,000 kilometers (8,900 miles) away. We know that Rhea's albedo overall is quite high. (When I say "albedo," I basically mean "brightness" or "reflect ... read more |

Pasadena CA (JPL) Mar 05, 2010NASA's newest Mars orbiter, completing its fourth year at the Red Planet next week, has just passed a data-volume milestone unimaginable a generation ago and still difficult to fathom: 100 terabits. That 100 trillion bits of information is more data than in 35 hours of uncompressed high-definition video. It's also more than three times the amount of data from all other deep-space missions ... more  
Warsaw (AFP) March 2, 2010Poland on Tuesday agreed to a new version of a deal on stationing an American missile shield, a government statement said, adding it would be aimed essentially at potential threats from Iran.

Pasadena CA (JPL) Mar 04, 2010Extensive radar mapping of the middle-latitude region of northern Mars shows that thick masses of buried ice are quite common beneath protective coverings of rubble. The ability of NASA's Mars Reconnaissance Orbiter to continue charting the locations of these hidden glaciers and ice-filled valleys - first confirmed by radar two years ago - adds clues about how these deposits may have been ... more |

NASA Radar Finds Ice Deposits At Moon's North PoleWashington DC (SPX) Mar 02, 2010 Using data from a NASA radar that flew aboard India's Chandrayaan-1 spacecraft, scientists have detected ice deposits near the moon's north pole. NASA's Mini-SAR instrument, a lightweight, synthetic aperture radar, found more than 40 small craters with water ice. The craters range in size from 1 to 9 miles (2 to15 km) in diameter. Although the total amount of ice depends on its thickness in each crater, it's estimated there could be at least 1.3 million pounds (600 million metric tons) of water ic ... read more |
