Underneath Phoenix Lander 97 Sols After Touchdown
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 Spiky Probe On Phoenix Raises Vapor Quandary 
Tucson AZ (SPX) Sep 05, 2008A fork-like conductivity probe has sensed humidity rising and falling beside NASA's Phoenix Mars Lander, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry. "If you have water vapor in the air, every surface exposed to that air will have water molecules adhere to it that are somewhat mobile, even at temperatures well below freezing ... more |

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 Mars Research In Polar Bear Country 
Moffett Field CA (SPX) Sep 02, 2008Hans Amundsen is a Norwegian geologist and the expedition leader of AMASE (Arctic Mars Analog Svalbard Expedition). AMASE is an international, interdisciplinary scientific research project that since 2003 has traveled to Svalbard, a group of islands in the High Arctic that provides some of the best sites on Earth for doing Mars-related field research. Among the most valuable geologic ... more |

Boston MA (SPX) Sep 01, 2008Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica's mars-like McMurdo Dry Valleys. The parallels between the Martian gullies and those in Antarctica's McMurdo Dry Valleys were made using the latest ... more Phoenix Lander Pictures Show Robotic Arm's Workspace After 90 Sols 
Tempe AZ (SPX) Aug 29, 2008New pictures from NASA's Phoenix Lander show just what a busy summer the spacecraft on Mars - and its science team at The University of Arizona in Tucson - has been having. During the first 90 Martian days, or sols, after its May 25, 2008, landing on an arctic plain of Mars, the lander dug several trenches in the workspace reachable for its robotic arm. The lander's Surface Stereo ... more Fresh From Mars: Scientist To Describe H20 Discovery 
Dallas TX (SPX) Aug 28, 2008Water on Mars? Scientists suspected the presence of H2O on the surface of our planetary next-door neighbor, but it took a series of tests and University of Texas at Dallas Professor John Hoffman's instrument aboard NASA's Phoenix Mars Lander to prove it. Hoffman will tell audiences at the Museum of Nature and Science on Aug. 30 how he and his team made one of this century's first major ... more NASA's Mars Rover Opportunity Climbing Out Of Crater 
Pasadena CA (SPX) Aug 27, 2008NASA's Mars Exploration rover Opportunity is heading back out to the Red Planet's surrounding plains nearly a year after descending into a large Martian crater to examine exposed ancient rock layers. "We've done everything we entered Victoria Crater to do and more," said Bruce Banerdt, of NASA's Jet Propulsion Laboratory in Pasadena, Calif. Banerdt is project scientist for Opportunity and ... more
