Liquid water has not been found on the Martian surface within the last decade after all, according to new research. The finding casts doubt on the 2006 report that the bright spots in some Martian gullies indicate that liquid water flowed down those gullies sometime since 1999. "It rules out pure liquid water," said lead author Jon D. Pelletier of The University of Arizona in Tucson. Pelletier and his colleagues used topographic data derived from images of Mars from the High Resolution...

Three Mars spacecraft are adjusting their orbits to be over the right place at the right time to listen to NASA's Phoenix Mars Lander as it enters the Martian atmosphere on May 25. Every landing on Mars is difficult. Having three orbiters track Phoenix as it streaks through Mars' atmosphere will set a new standard for coverage of critical events during a robotic landing. The data stream from Phoenix will be relayed to Earth throughout the spacecraft's entry, descent and landing events. If...

Mars has an ethereal, tenuous atmosphere at less than 1 percent the surface pressure of Earth, so scientists working on The University of Arizona's High Resolution Imaging Experiment, or HiRISE, are challenged to explain the complex, wind-sculpted landforms they're now seeing in unprecedented detail. The HiRISE camera on NASA's Mars Reconnaissance Orbiter, the most powerful camera to orbit another planet, can see 20-inch-diameter features while flying at about 7,500 mph between 155 and 196...

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...

Hi Mom! Spirit, the dusty Mars rover twin with the bad leg, shows up in a photo taken by the University of Arizona's orbiting HiRISE camera as the rover heads for a safe winter refuge. The long-lived twin NASA rovers Spirit and Opportunity are on opposite sides of Mars, sniffing around and taking pictures as they creep about the planet. They relay their findings through one of the Mars orbiting satellites that sends signals back to Earth, where they are picked up by the Deep Space Network...

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...

Two crucial tools for a successful landing of America's latest mission to Mars, the radar and UHF radio on NASA's Phoenix Mars Lander, have passed in-flight checkouts. The ultra-high-frequency radio won't be turned on again until landing day, May 25, 2008, when it will relay communications from Phoenix to orbiters already in service around Mars. Since launch on Aug. 4, 2007, and until the day it reaches Mars, Phoenix is communicating directly with Earth via even higher frequency X-band...

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...
