Phoenix To Bake Ice-Rich Sample Next Week
Pasadena CA (SPX) Jul 03, 2008The next sample delivered to NASA's Phoenix Mars Lander's Thermal and Evolved-Gas Analyzer (TEGA) will be ice-rich. A team of engineers and scientists assembled to assess TEGA after a short circuit was discovered in the instrument has concluded that another short circuit could occur when the oven is used again. "Since there is no way to assess the probability of another short circuit ... more Rain Showers On Mars 
Berkeley CA (SPX) Jul 03, 2008A new analysis of martian soil data led by University of California, Berkeley, geoscientists suggests that there was once enough water in the planet's atmosphere for a light drizzle or dew to hit the ground, leaving tell-tale signs of its interaction with the planet's surface. The study's conclusion breaks from the more dominant view that the liquid water that once existed during the red ... more Planets Align For The Fourth Of July 
Huntsville AL (SPX) Jul 02, 2008On 4th of July weekend, NASA forecasts lights in the sky. No, not those lights. Look beyond the fireworks. Almost halfway up the western sky, just above the twilight glow of sunset, a trio of worlds is gathering: Saturn, Mars and the crescent Moon. The show gets going on Friday, July 4th. Red Mars and ringed Saturn converge just to the left of the bright star Regulus. The three lights make ... more Phoenix Scrapes Almost Perfect Icy Soil For Analysis
Pasadena CA (SPX) Jul 02, 2008NASA'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 ... more New Soil Analysis Suggests It Rained On Mars Long Ago

Tucson AZ (SPX) Jun 27, 2008NASA's Phoenix Mars Lander placed a sample of Martian soil in the spacecraft's wet chemistry laboratory today for the first time. Results from that instrument, part of Phoenix's Microscopy, Electrochemistry and Conductivity Analyzer, are expected to provide the first measurement of the acidity or alkalinity of the planet's soil. The analysis of this soil sample and others will help research ... more Phoenix Returns Treasure Trove For Science 
Pasadena CA (SPX) Jun 27, 2008NASA's Phoenix Mars Lander performed its first wet chemistry 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. ... more Martian Soil Good Enough For Asparagus 
by Jean-Louis SantiniWashington DC (AFP) Jun 27, 2008 Martian dirt is apparently good enough for asparagus to grow in, NASA scientists said Thursday, as they announced the results of a soil analysis collected by the US Phoenix Mars lander. "There is nothing about the soil that would preclude life. In fact it seems very friendly," said Samuel Kounaves, the project's lead chemist at the University of Arizona in ... more Giant Impact Explains Mars Dichotomy 
Santa Cruz CA (SPX) Jun 26, 2008The dramatic differences between the northern and southern hemispheres of Mars have puzzled scientists for 30 years. One of the proposed explanations--a massive asteroid impact--now has strong support from computer simulations carried out by two groups of researchers. Planetary scientists at the University of California, Santa Cruz, were involved in both studies, which appear in the June 2 ... more |

Washington (AFP) June 20, 2008Scientists rejoiced Friday after the Phoenix Mars lander confirmed their long-held belief that ice is hiding under the surface in the Red Planet's northern region. The lander's robotic arm started digging trenches into Martian soil after touching down near the planet's north pole on May 25, revealing a white substance that scientists had said could be either salt or ice. Phoenix flexed ... more Frozen Water Confirmed On Mars 
Pasadena CA (SPX) Jun 23, 2008Scientists relishing confirmation of water ice near the surface beside NASA's Phoenix Mars Lander anticipate even bigger discoveries from the robotic mission in the weeks ahead. "It is with great pride and a lot of joy that I announce that we have found proof that this hard bright material is really water ice and not some other substance," said Phoenix Principal Investigator Peter Smith of ... more Mars Science Is A Sublime Affair For Phoenix Lander
Tucson AZ (JPL) Jun 23, 2008Dice-size crumbs of bright material have vanished from inside a trench where they were photographed by NASA's Phoenix Mars Lander four days ago, convincing scientists that the material was frozen water that vaporized after digging exposed it. "It must be ice," said Phoenix Principal Investigator Peter Smith of the University of Arizona, Tucson. "These little clumps completely disappearing ... more Harris Selected For Potential New NASA Space Suit Communications System 
Melbourne FL (SPX) Jun 23, 2008Harris has been selected for a potential seven-year, $58 million contract to provide the RF communications/navigation system for the next-generation space suit supporting NASA's Constellation program. Harris is a member of the Oceaneering International, Inc. team. The primary goals of NASA's Constellation Program are to maintain an American presence in low Earth orbit, to return to the ... more
