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 - 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.
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.
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.
Blacksburg VA (SPX) Oct 14, 2004 - A Ph.D. student at Virginia Tech has research published this week in Nature that shows Mars probably had liquid water at some point, but likely for only a short time, geologically speaking.
Paris (ESA) Oct 12, 2004 - This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows a part of the southern highlands of Mars, called Promethei Terra.
Pasadena CA (JPL) Oct 12, 2004 - After working on Mars for three times as long as its primary three-month mission, Spirit is healthy and currently investigating the rock called Tetl in the Columbia Hills. In the language of the ancient Mayans, tetl means stone.
Moffett Field CA (SPX) Oct 11, 2004 - Opportunity may attempt to leave Endurance crater via a route marked as the Escape Hatch, if scientists and engineers consider it safe after taking a closer look.
Los Alamos NM (SPX) Oct 11, 2004 - University of California scientists working at Los Alamos National Laboratory, along with a scientist from Indiana University have devised a method for determining whether sulfate salts can account for evidence of water on Mars. The work could pave the way to a better understanding of the martian environment and the history of water on Mars.
Paris, France (ESA) Oct 08, 2004 - Most Mars Express scientific payload operations were suspended between 22 August and 27 September, due to a period of solar conjunction. During this time, however, radio science (MaRS) experiments of the solar corona were carried out. On the egress from conjunction all spacecraft systems were nominal.
Pasadena CA (JPL) 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.
