Surface Water May Have Existed Far Longer On Some Parts Of Mars
Tucson AZ (SPX) Sep 18, 2008Water may have played a role in shaping parts of the Martian landscape a billion years longer than previous studies have shown, according to a research team led by Catherine Weitz, a senior scientist with the Planetary Science Institute. Their research, to be published in "Geophysical Research Letters" and now available online, presents strong evidence that sustained and large-scale process ... more More Soil Delivered To Phoenix Lab 
Pasadena CA (SPX) Sep 17, 2008This image, taken by NASA's Phoenix Mars Lander's Surface Stereo Imager, documents the delivery of a soil sample from the "Snow White" trench to the Wet Chemistry Laboratory. A small pile of soil is visible on the lower edge of the second cell from the top. This deck-mounted lab is part of Phoenix's Microscopy, Electrochemistry and Conductivity Analyzer (MECA). The delivery was made ... more NASA Selects CU-Boulder To Lead Mars Mission 
Boulder CO (SPX) Sep 17, 2008In the largest research contract ever awarded to the University of Colorado at Boulder, the Laboratory for Atmospheric and Space Physics has been selected by NASA to lead a $485 million orbiting space mission slated to launch in 2013 to probe the past climate of Mars, including its potential for harboring life over the ages. The team, led by CU-Boulder's LASP, will design, build and ... more NASA Selects MAVEN Mission To Study Mars Atmosphere 
Washington DC (SPX) Sep 16, 2008NASA has selected a Mars robotic mission that will provide information about the Red Planet's atmosphere, climate history and potential habitability in greater detail than ever before. Called the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft, the $485 million mission is scheduled for launch in late 2013. The selection was evaluated to have the best science value and lowest ... more Opportunity Bids Farewell To Victoria 
Pasadena CA (SPX) Sep 16, 2008Opportunity has completed one of the most fantastic scientific campaigns of the Mars Exploration Rover mission -- the interior investigation of "Victoria Crater." After spending more than 340 Martian days, known as sols -- almost one Earth year -- inside the crater, Opportunity climbed back out on sol 1634 (Aug. 28, 2008). To do so, Opportunity retraced the wheel tracks the robotic ... more |

Pasadena CA (SPX) Sep 10, 2008The Robotic Arm Camera on NASA's Phoenix Mars Lander took this image on Sept. 1, 2008, at about 4 a.m. local solar time during the 97th Martian day, or sol, since landing. The view underneath the lander shows growth of the clumps adhering to leg strut (upper left) compared with what was present when a similar image was taken about three months earlier. The view in this Sol 97 image is south ... more Mars Valleys Formed During Long Period Of Episodic Flooding 
Santa Cruz CA (SPX) Sep 09, 2008A new study suggests that ancient features on the surface of Mars called valley networks were carved by recurrent floods during a long period when the martian climate may have been much like that of some arid or semi-arid regions on Earth. An alternative theory that the valleys were carved by catastrophic flooding over a relatively short time is not supported by the new results. ... more Rosetta Swings By Asteroid Steins 2867 On Route To Comet Churyumov 
Paris (AFP) Sept 5, 2008A European spacecraft racing through the asteroid belt skimmed past a 10-kilometre (six-mile) space rock on Friday to carry out its first scientific work in a decade-long trek into the Solar System, mission controllers said. In a minutely choreographed operation, the one-billion-euro (1.45-billion-dollar) unmanned probe Rosetta - launched in 2004 by the European Space Agency ... more Spirit Still Biding Time 
Pasadena CA (JPL) Sep 05, 2008Spirit continues to ride out the Martian winter by doing minimal activities to conserve power. The rover completes very light science observations every three to four Martian days, known as sols, and relays data to NASA's Odyssey orbiter to be transmitted to Earth every four sols. Otherwise, Spirit mostly sleeps. This pattern is not likely to change until sunlight on the rover's solar ... more |

Tucson AZ (SPX) Sep 03, 2008NASA's Phoenix Mars Lander, having completed its 90-day primary mission, is continuing its science collection activities. Science and engineering teams are looking forward to at least another month of Martian exploration. Due to the spacecraft's sufficient power and experiment capacity, NASA announced on July 31 that the mission would continue operations through Sept. 30. Once the lander ... more Phoenix Analyzing Deepest Soil Sample Yet 
Tucson, AZ (JPL) Sep 03, 2008Scientists have begun to analyze a sample of soil delivered to NASA's Phoenix Mars Lander's wet chemistry experiment from the deepest trench dug so far in the Martian arctic plains. Phoenix has also been observing movement of clouds overhead. The lander's robotic arm on Sunday sprinkled a small fraction of the estimated 50 cubic centimeters of soil that had been scooped up from the ... more Opportunity Facing New Challenges After Victoria Detour
Pasadena CA (JPL) Sep 03, 2008Opportunity faces several challenges on the way out of "Victoria Crater" but continues to make steady progress. The first of these is a traverse of approximately 10 meters (30 feet, a little longer than a double-decker bus) across a sandy, 17-degree slope. Opportunity is more than halfway through that part of the journey. The next is a drive across 30 to 50 meters (100 to 160 feet) ... more Giant Telescope Mirror Blank Is Perfect 
Tucson AZ (SPX) Sep 03, 2008The single-piece primary and tertiary mirror blank cast for the LSST is "perfect", say project astronomers and engineers. The LSST, or Large Synoptic Survey Telescope, a large survey telescope being built in northern Chile, requires three large mirrors to give crisp images over a record large field of view. The two largest of these mirrors are concentric and fit neatly onto a single mirror ... more
