Pasadena CA (JPL) Dec 15, 2004 - Opportunity has finished its work inside Endurance Crater and climbed out. Before leaving, the rover examined a transition point between dark and light rock layers about 20 meters (about 66 feet) from the rim of the crater.
Pasadena (JPL) Dec 13, 2004 - Scientists have identified a water-signature mineral called goethite in bedrock that the NASA's Mars rover Spirit examined in the Columbia Hills, one of the mission's surest indicators yet for a wet history on Spirit's side of Mars.
Moffet Field CA (SPX) Dec 13, 2004 - On January 25, Opportunity landed on Mars. The landing site, Meridiani Planum, was the flattest location scouted in the history of Mars exploration.
Pasadena CA (JPL) Dec 09, 2004 - A digital elevation map, produced from satellite data overlain on an image taken by the Mars Orbital Camera on NASA's Mars Global Surveyor spacecraft, shows changes in elevation along the trek of NASA's Mars Exploration Rover Spirit as of the rover's 328th martian day, or sol (Dec. 4, 2004).
Washington DC (UPI) Dec 9, 2004 - Atmospheric scientists may continue to disagree about whether Earth's climate is warming and what it means, but the community of planetary scientists has formed a strong consensus - and quickly - that liquid water once flowed on Mars.
Paris (ESA) Dec 09, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows a region of Reull Vallis in the southern hemisphere of Mars.
Pasadena CA (JPL) Dec 08, 2004 - During the 19 sols ending on sol 325 (Dec. 1), Spirit continued to explore in the Columbia Hills. Spirit reached a position northeast of a ridge called Machu Picchu and began crossing a 200-meter-wide (656-foot-wide) flat saddle area.
Moffett Field CA (SPX) Dec 08, 2004 - One of the primary goals of the rover missions was to learn once and for all if liquid water ever existed on the red planet. That question has now been answered, indicates Mark Lemmon of Texas A&M University's College of Geosciences.
Pasadena CA (JPL) Dec 07, 2004 - Opportunity has completed its super-high-resolution imaging and other remote sensing operations from the base of Burns Cliff, collecting more than 985 megabits of telemetry. Due to the large number of observations, the data management team has been working hard to manage available memory. Opportunity has now begun its journey out of Endurance Crater.
Moffett Field CA (SPX) Dec 07, 2004 - At the recent Division of Planetary Sciences conference in Louisville, Kentucky, Michael Mumma, Director of the Center for Astrobiology at NASA's Goddard Space Flight Center, announced that relatively high levels of methane had been detected on Mars.
Tucson AZ (SPX) Dec 07, 2004 - The camera that will take thousands of the sharpest, most detailed pictures of Mars ever produced from an orbiting spacecraft, was delivered Monday for installation on NASA's Mars Reconnaissance Orbiter.
Sacramento CA (SPX) Dec 06, 2004 - Aerojet recently test-fired a Viking flight spare rocket engine assembly in order to help design a new engine which will deliver the next rover to the surface of Mars in 2009.
San Mateo CA (SPX) Dec 06, 2004 - Dr. Dobb's Journal of Software Tools has launched a contest designed to challenge the skills of master software builders and software architects to solve a Mars Rescue Mission, a hypothetical manned spacecraft that has crashed on Mars.
Ithaca NY (SPX) Dec 03, 2004 - Scientists have long been tantalized by the question of whether life once existed on Mars. Although present conditions on the planet would seem to be inhospitable to life, the data sent back over the past 10 months by NASA's two exploration rovers, Spirit and Opportunity, showed a world that might once have been warmer and wetter - perhaps friendly enough to support microbial organisms
Pasadena CA (JPL) Dec 03, 2004 - The most dramatic findings so far from NASA's twin Mars rovers - telltale evidence for a wet and possibly habitable environment in the arid planet's past - passed rigorous scientific scrutiny for publication in a major research journal.
Moffett Filed CA (SPX) Dec 03, 2004 - The rovers Spirit and Opportunity have been exploring the surface of Mars for nearly a year. Among their many discoveries, the rovers have found evidence that liquid water probably once existed on the surface of the red planet.
