06.09.09 - NASA's Mars Reconnaissance Orbiter is examining Mars again with its scientific instruments after successfully transitioning out of a precautionary standby mode triggered by an unexpected June 3 rebooting of its computer.
06.04.09 - NASA's Mars Reconnaissance Orbiter is in safe mode and in communications with Earth after an unexpected rebooting of its computer.
03.03.09 - NASA's Mars Reconnaissance Orbiter has fully recovered from an unexpected computer re-set last week and resumed its scientific investigation of Mars.
02.25.09 - NASA's Mars Reconnaissance Orbiter unexpectedly rebooted its computer Monday morning, Feb. 23, and put itself into a limited-activity mode that is an automated safety response.
12.18.08 - Researchers using a powerful instrument aboard NASA's Mars Reconnaissance Orbiter have found a long-sought-after mineral on the Martian surface and, with it, unexpected clues to the Red Planet's watery past.
12.11.08 - NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase.
12.04.08 - Climate cycles persisting for millions of years on ancient Mars left a record of rhythmic patterns in thick stacks of sedimentary rock layers.
11.20.08 - NASA's Mars Reconnaissance Orbiter has revealed vast Martian glaciers of water ice under protective blankets of rocky debris at much lower latitudes than any ice previously identified on the Red Planet.
10.28.08 - NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars.
09.25.08 - NASA's Mars Reconnaissance Orbiter has revealed hundreds of small fractures exposed on the Martian surface that billions of years ago directed flows of water through underground Martian sandstone.
07.16.08 - Two studies based on data from NASA's Mars Reconnaissance Orbiter have revealed that the Red Planet once hosted vast lakes and a variety of other wet environments that had the potential to support life.
06.25.08 - New analysis of Mars' terrain using NASA spacecraft observations reveals what appears to be by far the largest impact crater ever found in the solar system.
05.15.08 - New observations from NASA's Mars Reconnaissance Orbiter indicate that the crust and upper mantle of Mars are stiffer and colder than previously thought.
04.09.08 - A new stereo view of Phobos, the larger and inner of Mars' two tiny moons, has been captured by a NASA spacecraft orbiting Mars.
03.03.08 - A NASA spacecraft in orbit around Mars has taken the first ever image of active avalanches near the Red Planet's north pole.
01.23.08 - Mars has an ethereal, tenuous atmosphere with less than one-percent the surface pressure of Earth, which challenges scientists to explain complex, wind-sculpted landforms seen with unprecedented detail in images from NASA's Mars Reconnaissance Orbiter.
12.11.07 - Scrutiny by NASA's newest Mars orbiter is helping scientists learn the stories of some of the weirdest landscapes on Mars, as well as more familiar-looking parts of the Red Planet.
11.13.07 - The flight team for NASA's Mars Reconnaissance Orbiter has put the spacecraft back into operations. Science instruments have been powered up, and observations of Mars have resumed.
10.10.07 - Less than a year since beginning the prime science phase of its mission, NASA's Mars Reconnaissance Orbiter has passed a mission-success milestone for the amount of data returned.
