The U.S. space agency says its Mars Reconnaissance Orbiter is working once again after an unexpected computer reboot last week. National Aeronautics and Space Administration engineers at the Jet Propulsion Laboratory in Pasadena, Calif., sent commands Monday to power up the spacecraft's science instruments. The scientists said Tuesday monitoring confirmed all instruments were working properly. The Mars Reconnaissance Orbiter unexpectedly rebooted its computer Feb. 23 and put itself into a...

HiRISE finds fractured lavas before now seen only on Earth. Unique fractures in lavas on ancient Mars suggest water occasionally flooded portions of the planet's surface. The fractures, known as "columnar joints," are the first that have been observed on a planet other than Earth. "Columnar joints form as cooling lava contracts," said Moses Milazzo, a geophysicist with the U. S. Geological Survey Astrogeology Team in Flagstaff. The characteristics of the column-like fractures can help...

Data from the Mars Reconnaissance Orbiter (MRO) suggest the discovery of ancient springs in the Vernal Crater, sites where life forms may have evolved on Mars, according to a report in Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. Hot springs have great astrobiological significance, as the closest relatives of many of the most ancient organisms on Earth can thrive in and around hydrothermal springs. If life forms have ever been present on Mars, hot spring deposits...

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. Surveying intact bedrock layers with the Compact Reconnaissance Imaging Spectrometer for Mars, or CRISM, scientists found carbonate minerals, indicating that Mars had neutral to alkaline water when the minerals formed at these locations more than 3.6 billion years ago. Carbonates, which...

The U.S. space agency says its Mars Reconnaissance Orbiter has completed its primary, two-year science mission. National Aeronautics and Space Administration scientists said the spacecraft has returned 73 terabits of data -- more than all earlier Mars missions combined. The orbiter initially moved into position 186 miles above the surface of Mars in October 2006, subsequently conducting approximately 10,000 targeted observation sequences of high-priority areas. NASA scientists said the...

The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments. The orbiter has returned 73 terabits of science data, more than all earlier Mars missions combined. The spacecraft will build on this record as it continues to examine Mars in unprecedented detail during its next two-year phase of science operations. Among the major findings...

A $2 pair of cardboard 3-D glasses is a must-have on holiday gift lists. The High Resolution Imaging Science Experiment, or HiRISE, team based at The University of Arizona today released 362 three-dimensional images of Mars taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter. Other Mars-orbiting cameras have taken 3-D views of Mars, but the HiRISE camera "“ the most powerful camera ever to orbit another planet "“ can resolve features as small as one meter, or 40...

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. Scientists analyzed data from the spacecraft's ground-penetrating radar and report in the Nov. 21 issue of the journal Science that buried glaciers extend for dozens of miles from the edges of mountains or cliffs. A layer of rocky debris blanketing the ice may have preserved the underground...
