Northwestern Testing Transistors For Radiation Resistance On Space Station
Evanston IL (SPX) Jun 12, 2008Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside of the International Space Station for radiation testing. Such transistors could prove helpful on long space missions, such as NASA's current Phoenix Mars Mission, since early experiments on Earth indicate ... more Technology Enrolled In Hunt For Life On Mars 
Chapel Hill NC (SPX) Jun 12, 2008Scientists looking for evidence of life on Mars have turned to technology invented by University of North Carolina at Chapel Hill researchers to help with their mission. A team from NASA's Jet Propulsion Laboratory in Pasadena, Calif., has created a device for use on the European ExoMars rover mission scheduled for launch in 2013. That space voyage is one of several planned expeditions to ... more Probe again fails to obtain Martian soil sample 
Washington (AFP) June 10, 2008Clumpy soil on Mars has further hampered the Phoenix lander's attempts to obtain samples for analysis by the spacecraft's test instruments, mission experts said. "Virtually none of the material made it down into the oven" after the probe dug up new soil clumps from the Martian permafrost with its robotic arm, William Boynton, an investigator for Phoenix's thermal and evolved gas analyzer ... more NASA Lander Will Sprinkle Martian Soil For Microscope To View 
Tucson AZ (SPX) Jun 11, 2008The team operating NASA's Phoenix Mars Lander plans to instruct the spacecraft in the next few days to use its Robotic Arm to sprinkle a spoonful of Martian soil onto a wheel that will rotate the sample into place for viewing by the spacecraft's Optical Microscope. Meanwhile, commands for Phoenix's activities today are to continue a set of atmosphere observations begun during the Martian ... more Aerojet Ships Propulsion System For Mars Science Laboratory Mission 
Sacramento CA (SPX) Jun 11, 2008Aerojet has shipped the rocket engines destined for use on NASA's Mars Science Laboratory (MSL). When MSL is launched in the fall of 2009 aboard the Atlas V, Aerojet will provide propulsion for every phase of the mission. The Atlas V will be configured with four Aerojet solid motors to provide an additional one million pounds of thrust to the launch vehicle. The Centaur upper stage will us ... more |

Washington (AFP) June 8, 2008A soil sample from the Martian arctic dug up by the Phoenix probe appears to be too firmly clumped to deliver any particles into the spacecraft's main test instrument, mission experts said. Apparently no testable bits from the 200 milliliters (12 cubic inches) of Martian permafrost which researchers hope will provide clues to whether the planet was once habitable for microbial life passed ... more McCain would like to see a man on Mars 
Washington (AFP) June 6, 2008Presumptive Republican White House nominee John McCain said Thursday he would like to see a manned mission to Mars as part of a "better set of priorities" for NASA that would better engage the public. At a townhall event in Florida, the Arizona senator was asked about funding for the US space agency's shuttle program, which is due to end in 2010. He said he "would be willing to spend ... more Phoenix Mars Lander Checking Soil Properties 
Pasadena CA (JPL) Jun 08, 2008The arm of NASA's Phoenix Mars Lander released a handful of clumpy Martian soil onto a screened opening of a laboratory instrument on the spacecraft Friday, but the instrument did not confirm that any of the sample passed through the screen. Engineers and scientists on the Phoenix team assembled at the University of Arizona are determining the best approach to get some of that material ... more Phoenix Captures Highest Resolution Images Ever From Surface Of Mars 
Tucson AZ (SPX) Jun 06, 2008A microscope on NASA's Mars Phoenix Lander has taken images of dust and sand particles with the greatest resolution ever returned from another planet. The mission's Optical Microscope observed particles that had fallen onto an exposed surface, revealing grains as small as one-tenth the diameter of a human hair. "We have images showing the diversity of mineralogy on Mars at a scale th ... more |

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 Energy Levels Reach Record Low For Fading Spirit Of Mars 
Pasadena CA (JPL) Jun 03, 2008Energy production reached a record low for Spirit this past week. On Sol 1560 (May 23, 2008), solar array input was 220 watt-hours (enough energy to light a 100-watt bulb for two hours and 12 minutes). On sol 1563, Spirit expended the highest amount of energy yet on running heaters to maintain minimum temperatures for batteries (30.6 watt-hours) and the miniature thermal emission spectrometer (5 ... more Phoenix Scoops Up Some Martian Soil
Pasadena CA (JPL) Jun 02, 2008One week after landing on far-northern Mars, NASA Phoenix spacecraft lifted its first scoop of Martian soil as a test of the lander's Robotic Arm. The practice scoop was emptied onto a designated dump area on the ground after the Robotic Arm Camera photographed the soil inside the scoop. The Phoenix team plans to have the arm deliver its next scoopful, later this week, to an instrument tha ... more
