Moffett Field CA (SPX) Nov 01, 2004 - On Earth, gravity-driven south polar cap winds are termed catabatic winds. They are caused by the downward motion of cold air. Catabatic winds begin over the smooth expanse of the cap interior due to temperature differences between the atmosphere and the surface.
Moffett Field CA (SPX) Nov 01, 2004 - Strings of depressions dotting the Martian landscape indicate that seismic activity - marsquakes - may still be reshaping the surface of the planet, according to Dr. David Ferrill of Southwest Research Institute in a paper published in the October 10 issue of GSA Today. These pit chains occur along dilational faults, partially filled or open cavities that served as conduits for past groundwater flow.
Pasadena CA (SPX) Nov 01, 2004 - A view of the sundial-like calibration target on NASA's Mars Exploration Rover Spirit, with a bit of martian terrain in the background, is the 50,000th image from the twin rovers that have been exploring Mars since January.
Montreal QC (SPX) Oct 29, 2004 - Mars Society Canada (MSC), in conjunction with CASI - Concordia University, held a successful night of Mars related presentations in Montreal on October 28, 2004.
Ann Arbor MI (SPX) Oct 29, 2004 - A University of Michigan scientist is part of a European Space Agency team that has detected methane gas on Mars, the clearest indicator yet that there could be life there, said Sushil Atreya, professor and director of the Planetary Science Laboratory in the College of Engineering.
Paris, France (SPX) Oct 28, 2004 - Since the arrival of Mars Global Surveyor and more recently Mars Odyssey spacecrafts, a range of facts has revealed the existence of frozen water ice in the top meters of high latitudes near-surface (~60 deg - 90 deg) of both martian hemispheres. However, its origin was still unexplained.
New Haven CT (SPX) Oct 26, 2004 - Scientists in the department of Geology and Geophysics at Yale University have devised a method to precisely date the timing and temperature of a meteorite impact on Mars that led to ejection of a piece of the planet into space and its eventual impact on Earth.
Pasadena CA (JPL) Oct 26, 2004 - Spirit is healthy and currently investigating a layered rock called Uchben. Spirit is farther from the equator than its twin, Opportunity is, and it has much less available solar energy. Spirit's solar panels are pointed to the northern Sun, but Spirit is still only getting about 400 watt-hours of energy per day - enough to run a 100-watt bulb for four hours.
NASA's Opportunity rover continues to operate without any major issues after spending 130 sols inside "Endurance Crater". To date, the rover has…
Pasadena CA (JPL) Oct 21, 2004 - A problem that affects the steering on NASA's Mars Exploration Rover Spirit has recurred after disappearing for nearly two weeks. Engineers at NASA's Jet Propulsion Laboratory, Pasadena, Calif., are working to fully understand the intermittent problem and then implement operational work-arounds.
Pasadena CA (JPL) Oct 21, 2004 - Spirit had a productive week investigating the rock Tetl. On sol 277, Spirit attempted a drive to the next rock target, Uchben, which means ancient in the old Mayan language.
Paris (ESA) Oct 20, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the eastern rim of the Martian impact crater Huygens.
Moffett Field CA (SPX) Oct 19, 2004 - The Mars Exploration Rover (MER) mission has sent back groundbreaking information about the history of Mars. The most important result is the discovery of salt deposits that indicate that some regions of the planet were once drenched in water.
Washington (UPI) Oct 15, 2004 - It was the best of times, it was the worst of times, as the storyline begins. Shifted to a planetary context, the classic Dickens phrase also can be applied to Earth and Mars.
Las Cruces NM (SPX) Oct 15, 2004 - Two Mars Exploration Rovers are currently giving the public a taste of the information that can be sent back from the surface of Mars. Future expeditions to Mars are expected to gather even more information - and require more sophisticated technology to send this information back to Earth.
Pasadena CA (DSPX) Oct 14, 2004 - Opportunity is in excellent health. The current pattern is to use the deep-sleep mode every second night, and to support an early morning Odyssey communications pass on the non-deep-sleep nights.
