Simulations Predicted Mars Lander Would Hit Subsurface
Ann Arbor MI (SPX) Jun 06, 2008University of Michigan simulations correctly predicted that the pulsed jets of the Mars Phoenix lander would strip the soil to the subsurface ice or rock as the craft touched down. Photos of the area beneath the craft on Friday revealed a hard surface that scientists say may be ice. It could also be rock, and researchers won't know until the Phoenix can dig into the dirt. But it's clear th ... more NASA chief backs proposal for European spaceship 
Paris (AFP) June 5, 2008NASA chief Mike Griffin on Thursday threw his weight behind calls for Europe to build its own manned spacecraft. The experience of the US shuttle, to be retired in 2010, highlighted the need for multiple systems to provide backup for the International Space Station (ISS), Griffin told reporters in Paris. Griffin praised a robot European freighter that carried out a maiden automatic docki ... more Third Scoop Is A Keeper For Phoenix Mars Lander 
Tucson AZ (SPX) Jun 06, 2008Two practice rounds of digging and dumping the clumpy soil at the Martian arctic site this week gave scientists and engineers gathered at the University of Arizona confidence to begin using Phoenix's Robotic Arm to deliver soil samples to instruments on the lander deck. Those samples will not be collected before Thursday. Following Wednesday's briefing on the mission, the Phoenix tea ... more Biological Stowaways On Mars 
by Michael Schirberfor Astrobiology Magazine Current and upcoming missions to Mars hope to find some sign of past or present life in martian soil. But a constant worry is that biological contamination on the spacecraft will lead to a false detection. New research adds to these concerns with evidence that ATP -- an energy-storage molecule vital to life on Earth -- could survive for months or even ... more Iron-Coated Fossils Hold Clues To Possible Signs Of Martian Life 
Moffett Field CA (SPX) Jun 06, 2008Fossil microbes found along an iron-rich river in Spain reveal how signs of life could be preserved in minerals found on Mars. The discovery may help to equip the next generation Mars rover with the tools it would need to find evidence of past life on the planet. The Rio Tinto arises from springs west of Seville. These springs percolate up through iron ores that were deposited by geotherma ... more |

Tucson AZ (SPX) Jun 03, 2008Scientists have discovered what may be ice that was exposed when soil was blown away as NASA's Phoenix spacecraft landed on Mars last Sunday, May 25. The possible ice appears in an image the robotic arm camera took underneath the lander, near a footpad. "We could very well be seeing rock, or we could be seeing exposed ice in the retrorocket blast zone," said Ray Arvidson of Washington Univ ... more Mars probe Phoenix flexes robotic arm 
Washington (AFP) May 29, 2008NASA's Phoenix Mars lander flexed its robotic arm Thursday in a successful test of the key element in the probe's mission to investigate the Red Planet's soil for conditions conducive to life, NASA said. "The arm is ready to go," said Matt Robinson of the US space agency's Jet Propulsion Laboratory in Pasadena, California, where the Phoenix mission is managed. "Yesterday we sent commands ... more ATK Ultraflex Solar Arrays Deploy And Provide Critical Power To The Mars Phoenix Lander
Minneapolis MN (SPX) May 29, 2008Alliant Techsystems reports that the Ultraflex Solar Arrays deployed and now provide power to the Mars Phoenix Lander. This is the first flight for this unique solar array technology developed by ATK's Goleta, California facility. Each Ultraflex array unfolded like an oriental fan into a circular shape 2.1 meters in diameter and will generate 770 watts of power from sunlight at the distanc ... more Phoenix Spacecraft Commanded To Unstow Arm 
Tucson (LPL) May 29, 2008Scientists leading NASA's Phoenix Mars mission from the University of Arizona in Tucson sent commands to unstow its robotic arm and take more images of its landing site early today. The Phoenix lander sent back new sharp color images from Mars late yesterday. Phoenix imaging scientists made a color mosaic of images taken by the lander's Surface Stereo Imager on landing day, May 25, and th ... more |

Moscow (RIA Novosti) May 28, 2008It looks as if the Americans have turned their attention to the Red Planet for real. NASA's Phoenix Mars Lander touched down near the North Pole on May 25. The first shots sent back to the Jet Propulsion Laboratory (JPL) in California report that the probe is in excellent health. NASA is exhilarated. The very fact of a safe landing on Martian soil is already a success considering that it is the ... more Radio glitch hinders Mars lander mission 
Washington (AFP) May 27, 2008A communications glitch between the Phoenix Mars probe and Earth has delayed operations, two days after the spacecraft landed on the Red Planet in search of conditions to support life, NASA said Tuesday. A "transient event" knocked out UHF radio transmissions between Phoenix and the Mars Reconnaissance Orbiter (MRO), which relays data and instructions between the Phoenix and Earth, said Fuk ... more NASA Mars Lander Prepares To Move Arm 
Pasadena CA (JPL) May 28, 2008NASA's Phoenix Lander is ready to begin moving its robotic arm, first unlatching its wrist and then flexing its elbow. Mission scientists are eager to move Phoenix's robotic arm, for that arm will deliver samples of icy terrain to their instruments made to study this unexplored Martian environment. The team sent commands for moving the arm on Tuesday morning, May 27, to NASA's Mars R ... more NASA probe sends first pictures from Martian arctic 
Washington (AFP) May 26, 2008A NASA probe sent back never-before-seen pictures of Mars' north pole Monday, in the most ambitious mission to date to find life-sustaining minerals on the Red Planet. After NASA's Phoenix Mars probe made a near perfect landing at the Martian polar region late Sunday, scientists pored over images revealing a desolate frozen tundra. "We can see cracks in the troughs that make us think the ... more
