The U.S. space agency says the next sample of Martian soil to be analyzed by the Phoenix Mars Lander might be its last. A team of National Aeronautics and Space Administration engineers and scientists who assessed the spacecraft's Thermal and Evolved-Gas Analyzer, or TEGA, after a short circuit was discovered last month has concluded another short circuit could occur when the oven is again used. Since there is no way to assess the probability of another short circuit occurring, we are...

NASA's Phoenix Mars Lander enlarged the "Snow White" trench and scraped up little piles of icy soil on Saturday, June 28, the 33rd Martian day, or sol, of the mission. Scientists say that the scrapings are ideal for the lander's analytical instruments. The robotic arm on Phoenix used the blade on its scoop to make 50 scrapes in the icy layer buried under subsurface soil. The robotic arm then heaped the scrapings into a few 10- to 20-cubic centimeter piles, or piles each containing between two...

NASA's Phoenix Mars Lander scraped to icy soil in the "Wonderland" area on Thursday, June 26, confirming that surface soil, subsurface soil and icy soil can be sampled at a single trench. Phoenix scientists are now assured they have a complete soil-layer profile in Wonderland's "Snow White" extended trench. By rasping to icy soil, the robotic arm on Phoenix proved it could flatten the layer where soil meets ice, exposing the icy flat surface below the soil. Scientists can now proceed with...

NASA's Phoenix Mars Lander performed its first wet chemistry experiment on Martian soil flawlessly yesterday, returning a wealth of data that for Phoenix scientists was like winning the lottery. "We are awash in chemistry data," said Michael Hecht of NASA's Jet Propulsion Laboratory, lead scientist for the Microscopy, Electrochemistry and Conductivity Analyzer, or MECA, instrument on Phoenix. "We're trying to understand what is the chemistry of wet soil on Mars, what's dissolved in it, how...

NASA scientists said Thursday that the soil on Mars appears to have elements favorable to supporting life. The "flabbergasted" scientists are part of the Phoenix Mars Lander mission. They said a preliminary analysis on a soil sample obtained by the spacecraft's 8-foot robotic arm had shown the Martian soil to be much more alkaline than expected. "We basically have found what appears to be the requirements, the nutrients, to support life whether past present or future," Sam Kounaves, the...

The U.S. space agency said its Phoenix Mars Lander was ready to conduct a microscopic analysis of Martian soil Thursday -- the 29th day of the mission. The soil was to undergo examination under the lander's optical microscope, with Phoenix's robotic arm to deliver some of that same scoop of soil for the first wet chemistry experiment on Mars. That experiment is to be conducted later this week. National Aeronautics and Space Administration scientists made a diagnostic test run Monday that...

TUCSON, Ariz. -- NASA's Phoenix Mars Lander has delivered a scoop of Martian soil from the "Snow White" trenches to the optical microscope for analysis tomorrow, June 24, the 29th Martian day of the mission, or Sol 29. And the Phoenix lander will position its Robotic Arm to deliver some of that same scoop of soil for its first wet chemistry experiment on the Red Planet in the next day or two. Scientists did a diagnostic run today that melted ice to water for Phoenix's first wet chemistry...

By the associated press LOS ANGELES - Scientists believe NASA's Phoenix Mars lander exposed bits of ice while recently digging a trench in the soil of the Martian arctic, the mission's principal investigator said. Crumbs of bright material initially photographed in the trench later vanished, meaning they must have been frozen water that vaporized after being exposed, Peter Smith of the University of Arizona, Tucson, said in a statement Thursday. "These little clumps completely...

By JOHN VON RADOWITZ WATER ice was discovered on Mars yesterday by the Phoenix probe which landed on the planet last month. Mission controllers had been excited by chunks of white material in the Martian soil exposed by the craft's robot arm. Yesterday, scientists confirmed what they had hoped . . . that the material was frozen water. Phoenix principal investigator Dr Peter Smith said: "It is with great pride and a lot of joy that I announce today that we have found proof that this...
