College Station TX (SPX) Aug 11, 2004 - Suspected large lakebeds that once were scattered on the planet Mars have not yet been found, say the research team that operated the twin rovers Spirit and Opportunity. Their work appears in the current issue of Science magazine.
Pasadena CA (JPL) Aug 11, 2004 - Sol 188 was devoted to finishing an examination of a target patch called Tuktoyuktuk where the rover's rock abrasion tool had ground the surface coating off of a rock called Inuvik. Opportunity then drove partly up-slope and partly cross-slope as both a mobility test and the start of a traverse to the next target. It slipped down-slope about as much as expected, a good result.
Paris (ESA) Aug 11, 2004 - ESA's Mars Express has relayed pictures from one of NASA's Mars rovers for the first time, as part of a set of interplanetary networking demonstrations. The demonstrations pave the way for future Mars missions to draw on joint interplanetary networking capabilities. ESA and NASA planned these demonstrations as part of continuing efforts to co-operate in space exploration.
Paris (ESA) Aug 10, 2004 - These images from ESA's Mars Express show the western flank of the shield volcano Olympus Mons in the Tharsis region of the western Martian hemisphere.
Pasadena (JPL) Aug 10, 2004 - With one very busy year remaining before launch, the team preparing NASA's next mission to Mars has begun integrating and testing the spacecraft's versatile payload. Possible launch dates from Cape Canaveral, Fla., for NASA's Mars Reconnaissance Orbiter begin Aug. 10, 2005. The spacecraft will reach Mars seven months later to study the surface, subsurface and atmosphere with the most powerful instrument suite ever flown to the red planet.
Pasadena CA (JPL) Aug 09, 2004 - As NASA's Mars Exploration Rover Opportunity creeps farther into Endurance Crater, the dune field on the crater floor appears even more dramatic. This approximate true-color panoramic camera image highlights the reddish-colored dust present throughout the scene.
Pasadena CA (JPL) Aug 09, 2004 - The rock abrasion tool has been keeping busy at Opportunity's position about 22 meters (72 feet) inside of Endurance Crater while rover handlers are preparing for Opportunity's next traverse.
Moffett Field CA (SPX) Aug 09, 2004 - Scientific findings from the NASA rover Spirit's first three months on Mars will be published Friday, marking the start of a flood of peer-reviewed discoveries in scientific journals from the continuing two-rover adventure.
Pasadena CA (JPL) Aug 06, 2004 - Scientific findings from the NASA rover Spirit's first three months on Mars will be published Friday, marking the start of a flood of peer-reviewed discoveries in scientific journals from the continuing two-rover adventure.
Ithaca NY (SPX) Aug 06, 2004 - After more than six months of examining the photographic and spectral data from the rover, Mars mission scientists confirm that the albedo - which is the percentage of sunlight reflected on the red planet's dusty surface - indicates important variations in mineral and dust composition.
Paris (ESA) Aug 05, 2004 - This image of the southern part of Valles Marineris, called Melas Chasma, was obtained by the High Resolution Stereo Camera (HRSC) on board the ESA Mars Express spacecraft.
Pasadena CA (JPL) Aug 05, 2004 - NASA's Spirit rover has climbed higher into rocky hills on Mars, and its twin, Opportunity, has descended deeper into a crater, but both rovers, for the time being, are operating with some restrictions while team members diagnose unexpected behavior.
Pasadena CA (JPL) Aug 04, 2004 - Millions of people have viewed pictures from NASA's Spirit on the Mars rovers home page and other Internet sites. Beginning today, a more complete set of science data from Spirit's first 30 martian days is posted on a site primarily for scientists and technical researchers, but also available to anyone who's interested.
Pasadena CA (JPL) Aug 03, 2004 - Opportunity marked its 180th sol on Mars without pausing to celebrate. Originally slated for missions of 90 sols each, both Spirit and Opportunity have passed the double-mission milestone and are continuing their phenomenal journeys of discovery.
Moffett Field CA (SPX) Aug 03, 2004 - NASA scientists have modified a scientific Web site so the general public can inspect big regions and smaller details of Mars' surface, a planet whose alien terrain is about the same area as Earth's continents.
Pasadena CA (JPL) Jul 29, 2004 - On sol 198, Spirit completed a long overnight reading by the Moessbauer spectrometer on a rock target called Sabre, then ground a second rock abrasion tool hole on a target called Mastodon. The alpha particle X-ray spectrometer was placed in the fresh hole in preparation for a reading, which was started during the overnight Odyssey communication pass.
