November 2008
- Mars Lander Falls Silent
  
  NASA | Nov 10, 08 5:11 PM CST
  
  (Newser) - The Martian autumn has cut power to NASA’s Phoenix Mars Lander, ending its mission of scientific discovery, NASA reports. As anticipated, shorter days and increasingly overcast skies are preventing sufficient solar energy from reaching the lander’s power cells. It has already collected data for 2 months longer than its originally planned 90-day mission, yielding information crucial to understanding Mars’ environment. More »

- Mission Accomplished on Mars
  
  Wired | Aug 29, 08 5:32 PM CDT
  
  (Newser) - Time's almost up for NASA's Mars Phoenix Lander: With its 90-day mission complete, the $480 million project will continue testing soil samples until the punishing winter puts it out of commission. Wired recaps Phoenix triumphs with an interactive timeline, from its flawless landing at Mars' north pole to its groundbreaking analysis of Martian ice and water. More »
- Mars Toxin Dims Hopes for Red Planet Life
  
  Space.com | Aug 5, 08 8:55 AM CDT
  
  (Newser) - The Phoenix lander has found a toxin in Mars soil that considerably decreases the odds of finding Martian life, Science.com reports. The chemical, perchlorate, is a harsh oxidizing agent often used in solid rocket fuel, so researchers are double checking to ensure it wasn’t carried from Earth. The results are especially surprising because Sunday’s tests revealed no sign of perchlorate. More »
- NASA Briefs White House on Possible Martian Life
  
  Aviation Week | Aug 2, 08 3:23 PM CDT
  
  (Newser) - NASA has briefed the White House on its plan to announce a new finding on the "potential for life" on Mars, Aviation Week reports. NASA has no evidence that the red planet has harbored life, but new Phoenix lander discoveries suggest it is possible—a finding that Phoenix officials call far more “provocative” than the mere presence of water.

- NASA Lander Confirms Water on Mars
  
  Associated Press | Jul 31, 08 8:50 PM CDT
  
  (AP) - The Phoenix spacecraft has tasted Martian water for the first time. By melting icy soil in one of its lab instruments, the robot confirmed the presence of frozen water lurking below the Martian permafrost. Until now, evidence of ice in Mars' north pole region has been largely circumstantial. Scientists popped open champagne today when they received confirmation. More »
- Sticky Soil Foils Mars Work
  
  Space.com | Jul 28, 08 8:19 AM CDT
  
  (Newser) - NASA is revising its soil-harvesting method because the Phoenix Mars lander is having trouble with its icy finds, Space.com reports. The lander’s attempts to analyze the soil have been troubled because the soil is sticking to its scoop, stubbornly refusing to fall into the tiny oven designed to melt and study it. Next time, the scoop will dig less and vibrate more. NASA is studying the soil to see whether it could have ever supported life. More »
- AFP: New data reveals the wet and balmy past of Mars
  
  AFP | Jul 16, 08
  
  Water bathed the surface of southern Mars for millions of years, helping to create an environment theoretically capable of nurturing life, according to a new study into the planet's mysterious oceans.
- AFP: Phoenix scientists soon will analyze Martian ice
  
  AFP | Jul 3, 08
  
  Scientists with the US Phoenix lander will make their first analysis of Martian ice fragments in coming days but it could be the last done in one of the probe's small ovens, NASA said on its website Friday.

  Reuters | Jun 26, 08 4:47 PM CDT
  
  (Newser) - Samples of Martian soil analyzed by instruments onboard the Phoenix lander have earth-bound scientists “flabbergasted.” Why? Readings indicate that the extraterrestrial loam could, perhaps has, and possibly will, support life, Reuters reports. Along with ice the lander discovered earlier, “We basically have found what appears to be the requirements, the nutrients, to support life,” a scientist said. More »
- Scientists Hail Ice Find on Mars
  
  Wired | Jun 20, 08 4:49 AM CDT
  
  (Newser) - White material on Mars that was puzzling NASA scientists has turned out to be ice, Wired reports. "Are you ready to celebrate? We have ICE! Best day ever!" gushed a team scientist. The discovery of evidence of water—essential for terrestrial life—is exactly what scientists were hoping to find on Mars. More »
