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...

NASA's Mars Reconnaissance Orbiter has observed a new category of minerals spread across large regions of Mars. This discovery suggests that liquid water remained on the planet's surface a billion years later than scientists believed, and it played an important role in shaping the planet's surface and possibly hosting life. Researchers examining data from the orbiter's Compact Reconnaissance Imaging Spectrometer for Mars have found evidence of hydrated silica, commonly known as opal. The...

Clay deposits found in one of the oldest riverbed-like channels on Mars shows some unusual signatures that may shed light on the history of water -- and possibly life -- on the red planet. Observations made by an instrument onboard NASA's Mars Reconnaissance Orbiter (MRO), currently circling the planet, already have shown substantial clay deposits that formed about 4 billion years ago in two regions of Mars, Mawrth Vallis and Nili Fossae, that indicate that water was more...

New findings show diverse, wet environments on ancient Mars WASHINGTON, July 16 (Xinhua) -- Mars once hosted vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life, according to two new studies based on data from instruments on board NASA's Mars Reconnaissance Orbiter (MRO). By combining data from these high-tech instruments, scientists have identified three principal classes of water-related minerals dating to the early history of...

WASHINGTON -- Two studies based on data from NASA's Mars Reconnaissance Orbiter have revealed that the Red Planet once hosted vast lakes, flowing rivers and a variety of other wet environments that had the potential to support life. One study, published in the July 17 issue of Nature, shows that vast regions of the ancient highlands of Mars, which cover about half the planet, contain clay minerals, which can form only in the presence of water. Volcanic lavas buried the clay-rich regions...

SAN FRANCISCO - 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. One type of landscape near Mars' south pole is called "cryptic terrain" because it once defied explanation, but new observations bolster and refine recent interpretations of how springtime outbursts of carbon-dioxide gas there sculpt intricate patterns and paint seasonal splotches. "A lot of Mars...

Scientists scouting potential landing sites for NASA's next Mars rover mission are using new data from a powerful mineral-mapping camera to narrow the site selection. When NASA Mars Program officials and members of the Mars science community gather in California next week to pare down the list of candidate landing sites for the 2009 Mars Science Laboratory (MSL), they can refer to 125 new images from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). The images and accompanying...

PASADENA, CALIF. -- 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. The data-volume target of 26 terabytes, which was surpassed this week, is equivalent to about 5,000 CD-ROMs full and exceeds the total from all other current and past Mars missions combined. The biggest shares of the data come from two of the orbiter's six science instruments: the High Resolution...

PASADENA, Calif. -- NASA's Mars Reconnaissance Orbiter is examining several features on Mars that address the role of water at different times in Martian history. Features examined with the orbiter's advanced instruments include material deposited in two gullies within the past eight years, polar ice layers formed in the recent geologic past, and signs of water released by large impacts when Mars was older. Last year, discovery of the fresh gully deposits from before-and-after images taken...

Diagnostic tests and months of stable, successful operation have resolved concerns raised early this year about long-term prospects for the powerful telescopic camera on NASA's Mars Reconnaissance Orbiter. The High Resolution Imaging Science Experiment (HiRISE) camera on the orbiter has now taken more than 3,000 images of Mars, resolving features as small as a desk in targeted areas covering thousands of square miles of the Martian surface. Already, this is the largest Mars data set ever...
