Water Ideas Are All Wet
Moffett Field CA (SPX) Aug 14, 2008According to new research, old ideas about water behavior are all wet. Ubiquitous on Earth, water also has been found in comets, on Mars and in molecular clouds in interstellar space. Now, scientists say this common fluid is not as well understood as we thought. "Water, as we know it, does not exist within our bodies," said Martin Gruebele, a William H. and Janet Lycan Professor of Chemist ... more PSI Director Promotes 13-Planet Solar System 
Columbia, Maryland (SPX) Aug 13, 2008Mark Sykes says that if a non-stellar object is massive enough to be round and orbits a star, it ought to be a planet. The key here is that once an object gets that big, important geophysical processes begin. Under this scenario, the smallest known planet in the solar system would be Ceres, the largest and most massive object in the asteroid belt between Mars and Jupiter. Ceres is less ... more Soil Studies Continue At Phoenix Mars Lander Site 
Pasadena CA (SPX) Aug 13, 2008Vibration of the screen above a laboratory oven on NASA's Phoenix Mars Lander on Saturday, Aug. 9, succeeded in getting enough soil into the oven to begin analysis. Commands were sent for the lander's Thermal and Evolved-Gas Analyzer (TEGA) to begin analysis Sunday of the soil sample from a trench called "Rosy Red." Phoenix's robotic arm delivered soil Thursday from the Rosy Red trench ... more Preparation Begins For New European Space Mission To Mars 
Paris, France (ESA) Aug 12, 2008Scientists searching for life on Mars are now preparing for the most in-depth probe of the Red Planet ever undertaken. The European Space Agency's ExoMars mission will search for evidence that life may exist, investigate the Martian upper atmosphere, and analyse the physical characteristics and properties of the planet's surface and interior. With a scheduled launch date of 2013 ... more Soil Studies Continue At Site Of Phoenix Mars Lander 
Tucson AZ (SPX) Aug 11, 2008NASA's Phoenix Mars Lander has continued studies of its landing site by widening a trench, making overnight measurements of conductivity in the Martian soil and depositing a sample of surface soil into a gap between partially opened doors to an analytical oven on the lander. Phoenix's robotic arm delivered soil Thursday from a trench informally named "Rosy Red" through a narrow opening to ... more |

Pasadena CA (SPX) Aug 11, 2008"Victoria Crater" continues to challenge Mars rover drivers as they try to find a location where Opportunity can do scientific studies of rocks near the "Cape Verde" cliff face. They have been trying to drive the rover to a location nicknamed "Nevada" after a rock shaped somewhat like the state of Nevada. Getting there, however, has been challenging. After attempting unsuccessfully to ... more With Batteries Charged, Spirit Is Ready For More Science 
Pasadena CA (SPX) Aug 08, 2008Spirit has fully recovered from a recent rundown in battery power. Energy has improved to levels not seen since sol (Martian day) 1604 (July 7, 2008). The hit in battery energy was primarily the result of data transmissions taking place later in the day, when less solar energy was available. During the past week, rover planners eliminated the late communications sessions. Spirit is not ... more Martian Clays Tell Story Of A Wet Past 
Mountain View CA (SPX) Aug 08, 2008Layers of clay-rich rock have been found in Mars' Mawrth Vallis, a potential landing site for future rovers. This work, published in the August 8 issue of Science, suggests that abundant water was once present on Mars and that hydrothermal activity may have occurred. The Mawrth Vallis outflow channel is a feature in Mars' northern highland region, a heavily cratered, ancient area of the ... more Perchlorate salts: a major find on Mars 
Tucson (UPI) Aug 6, 2008 U.S. space agency scientists say the discovery of perchlorate salts on Mars makes them reassess how they think about possible Martian life. Scientists involved with the Phoenix Mars Lander mission met Tuesday in an ongoing investigation of perchlorate salts detected in soil analyzed by the spacecraft's wet chemistry laboratory. The discovery of Martian perchlorates is exciting ... more |

Moscow (RIA Novosti) Aug 06, 2008Data gathered by NASA's Phoenix lander on Mars have revealed the red planet's soil could contain a toxic substance that would make it less likely that life formed there. Earlier NASA said Phoenix analyzers detected water in the soil, which suggested that Mars could have the conditions for life. However, if the presence of perchlorate were confirmed, the probability of detecting living ... more NASA Spacecraft Analyzing Martian Soil Data 
Pasadena CA (SPX) Aug 05, 2008Scientists are analyzing results from soil samples delivered several weeks ago to science instruments on NASA's Phoenix Mars Lander to understand the landing site's soil chemistry and mineralogy. Within the last month, two samples have been analyzed by the Wet Chemistry Lab of the spacecraft's Microscopy, Electrochemistry, and Conductivity Analyzer, or MECA, suggesting one of the soil ... more NASA extends 'successful' Phoenix lander mission
Los Angeles (AFP) July 31, 2008NASA scientists said Thursday the agency was extending the Mars mission of its Phoenix lander until the end of September, describing its progress so far as "very successful." Michael Meyer, chief scientist of NASA's Mars Exploration Program, told reporters at a briefing that the minimum objectives of the lander's mission had been achieved and that "full mission success" was expected. ... more Mission Extended As Phoenix Confirms Martian Water 
Tucson AZ (SPX) Aug 01, 2008Laboratory tests aboard NASA's Phoenix Mars Lander have identified water in a soil sample. The lander's robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples. "We have water," said William Boynton of the University of Arizona, lead scientist for the Thermal and Evolved-Gas Analyzer, or TEGA. "We've seen evidence for this ... more
