A growing bounty of images from NASA's Mars Reconnaissance Orbiter reveals that the timing of new activity in one type of the enigmatic gullies on Mars implicates carbon-dioxide frost, rather than water, as the agent causing fresh flows of sand. Researchers have tracked changes in gullies on faces of sand dunes in seven locations on southern Mars. The periods when changes occurred, as determined by comparisons of before-and-after images, overlapped in all cases with the known winter build-up...

PASADENA, Calif., Oct. 28 /PRNewswire-USNewswire/ -- The ground where NASA's Mars Exploration Rover Spirit became stuck last year holds evidence that water, perhaps as snow melt, trickled into the subsurface fairly recently and on a continuing basis.

The ground where NASA's Mars Exploration Rover Spirit became stuck last year holds evidence that water, perhaps as snow melt, trickled into the subsurface fairly recently and on a continuing basis. Stratified soil layers with different compositions close to the surface led the rover science team to propose that thin films of water may have entered the ground from frost or snow. The seepage could have happened during cyclical climate changes during periods when Mars tilted farther on its axis....

GREENBELT, Md., Oct. 5 /PRNewswire-USNewswire/ -- NASA's mission to investigate the mystery of how Mars lost much of its atmosphere passed a critical milestone on October 4, 2010. NASA has given approval for the development and 2013 launch of the Mars Atmosphere and Volatile Evolution (MAVEN) mission.

What will the Martian atmosphere be like when the next Mars rover descends through it for landing in August of 2012? An instrument studying the Martian atmosphere from orbit has begun a four-week campaign to characterize daily atmosphere changes, one Mars year before the arrival of the Mars Science Laboratory rover, Curiosity. A Mars year equals 687 Earth days. The planet's thin atmosphere of carbon dioxide is highly repeatable from year to year at the same time of day and seasonal date...

Mars Reconnaissance Orbiter Mission Status Report NASA's Mars Reconnaissance Orbiter resumed observing Mars with its science instruments on Sept. 18, recovering from an unplanned reboot of its computer three days earlier. The reboot put the orbiter into a precautionary standby called "safe mode" on Sept. 15. The event appears to have been similar to one the orbiter last experienced on Aug. 26, 2009. For 10 months prior to this latest reboot, the spacecraft operated normally, making science...

BOULDER, Colo., Sept. 22 /PRNewswire-FirstCall/ -- Ball Aerospace & Technologies Corp. will have a significant role on two of the five science instruments that will fly aboard the ExoMars Trace Gas Orbiter (TGO), a European-built spacecraft slated for launch to Mars in March 2016. The orbiter is a joint effort between NASA and the European Space Agency (ESA) to explore Mars in future decades. Ball Aerospace will provide the focal plane and electronics for the High Resolution Stereo...

NASA's Mars Reconnaissance Orbiter put itself into a precautionary standby mode after experiencing a spontaneous computer reboot on Sept. 15. The mission's ground team has begun restoring the spacecraft to full operations. Initial analysis of telemetry from the orbiter indicates the "safe mode" status was triggered by a reboot similar to one experienced Aug. 26, 2009. That was the most recent time that the Mars Reconnaissance Orbiter put itself into safe mode. For 10 months prior to this...

When NASA's Mars Exploration Rover Opportunity left Victoria Crater two years ago this month, the rover science team chose Endeavour Crater as the rover's next long-term destination. With a drive of 111 meters (364 feet) on Monday, Sept. 8, Opportunity reached the estimated halfway point of the approximately 19-kilometer (11.8-mile) journey from Victoria to the western rim of Endeavour. Opportunity completed its three-month prime mission on Mars in April 2004. During its bonus extended...

One of the instruments on a 2016 mission to orbit Mars will provide daily maps of global, pole-to-pole, vertical distributions of the temperature, dust, water vapor and ice clouds in the Martian atmosphere. The joint European-American mission, ExoMars Trace Gas Orbiter, will seek faint gaseous clues about possible life on Mars. This instrument, called the ExoMars Climate Sounder, will supply crucial context with its daily profiling of the atmosphere's changing structure. The European Space...
