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.
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).
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 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.
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.
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.
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.
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.
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.
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.
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 02, 2004 - Cloud watching has been one duty of NASA's Opportunity Mars Exploration Rover within the red planet's Meridiani Planum region. The robot is now wrapping up its exploration of Burns Cliff inside the stadium-sized Endurance Crater.
Paris, France (ESA) Nov 25, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows Crater Hale in the Argyre basin of the southern hemisphere of Mars.
Pasadena CA (JPL) Nov 25, 2004 - Opportunity has now reached the furthest point east in its travels inside Endurance Crater. Rover drivers have determined that there is no safe path beyond the current position.
Moffett Field CA (SPX) Nov 25, 2004 - As the rovers try to survive the dead of martian winter, what do readers want to know about their first nine-months on the red planet? Questions and answers range from how long the rovers may last to what it's like to live four months on martian time.
