Moffett Field CA (SPX) Oct 08, 2004 - NASA's Spirit and Opportunity have been exploring Mars about three times as long as originally scheduled. The more they look, the more evidence of past liquid water on Mars these robots discover. Team members reported the new findings at a news briefing today.
Bloomington IN (SPX) Oct 07, 2004 - Epsom-like salts believed to be common on Mars may be a major source of water there, say geologists at Indiana University Bloomington and Los Alamos National Laboratory. In their report in this week's Nature, the scientists also speculate that the salts will provide a chemical record of water on the Red Planet.
Paris, France (ESA) Oct 06, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the Ophir Chasma, a northern part of the Valles Marineris canyon.
Paris, France (ESA) Oct 06, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the Claritas Fossae tectonic grabens and part of the Solis Planum plains.
Pasadena CA (SPX) Oct 05, 2004 - Engineers on NASA's Mars Exploration Rover team are investigating possible causes and remedies for a problem affecting the steering on Spirit.
Pasadena CA (JPL) Oct 01, 2004 - Spirit has successfully transitioned back to normal operations from conjunction operations, when Mars and Earth were on opposite sides of the Sun. During conjunction (sols 244 through 255), engineers and scientists did not attempt normal operations due to the low probability of successful communications.
Houston (SPX) Sep 30, 2004 - It will be drilling for information first, then for resources, though oil is not likely to be among exploration targets.
Pasadena CA (JPL) Sep 28, 2004 - NASA's Mars Global Surveyor, starting its third mission extension this week after seven years of orbiting Mars, is using an innovative technique to capture pictures even sharper than most of the more than 170,000 it has already produced.
Paris, France (ESA) Sep 28, 2004 - Recent results from the ASPERA-3 instrument on board Mars Express confirm that a very efficient process is at work in the Martian atmosphere, which could explain the loss of water. Water is believed to have once been abundant on the Red Planet. Professor Rickard Lundin, leader of the ASPERA-3 team, describes these findings in a paper published in the latest issue of 'Science'.
Moffett Field CA (SPX) Sep 27, 2004 - If the martian canyon, Valles Marineris, were on Earth, it would stretch from New York to Los Angeles. It is the largest canyon in the solar system (more than 4,000 kilometers (2,500 miles) long with 5 to 10 kilometers (3 to 6 miles) relief from floors to tops of surrounding plateaus).
Moffett Field CA (SPX) Sep 23, 2004 - Carol Stoker is the principal investigator for the Mars Analog Research and Technology Experiment (MARTE). MARTE has just begun its second field season drilling into the subsurface near the headwaters of the Rio Tinto in Spain, searching for novel forms of microbial life.
Pasadena CA (JPL) Sep 22, 2004 - As NASA's Spirit and Opportunity resumed reliable contact with Earth, after a period when Mars passed nearly behind the sun, the space agency extended funding for an additional six months of rover operations, as long as they keep working.
Moffett Field CA (SPX) Sep 21, 2004 - Carol Stoker is the principal investigator for the Mars Analog Research and Technology Experiment (MARTE). MARTE has just begun its second field season drilling into the subsurface near the headwaters of the Rio Tinto in Spain, searching for novel forms of microbial life.
Paris, France (ESA) Sep 21, 2004 - Recent analyses of ESA's Mars Express data reveal that concentrations of water vapour and methane in the atmosphere of Mars significantly overlap.
Washington (UPI) Sep 21, 2004 - The old saying that big things can come in small packages might be exactly appropriate for a tiny but explosive amount of data that researchers have produced concerning Mars.
Pasadena CA (JPL) Sep 20, 2004 - The Spirit rover is now in a safe place to continue daily science observations automatically throughout its solar conjunction period when engineers and scientists will be unable to send commands reliably to the rover.
