Digging Deep For Martian Life

Moffett Field CA (ARC) Jul 24, 2007 - The European Space Agency (ESA), like NASA, has a plan to explore the solar system. ESA's Aurora Programme includes orbiters, landers, rovers, and ultimately, human exploration of the moon and Mars. ExoMars, a rover scheduled to launch in 2011 and to land on Mars in 2013, is one of Aurora's flagship missions. The ExoMars rover will be capable, for the first time since NASA's Viking missions in the 1970s, of searching for direct evidence of martian life.

Opportunity Calls Home After Some Solar Juice Cranks Up The Batteries

Los Angeles CA (JPL) Jul 24, 2007 - NASA's Mars Exploration Rover Opportunity sent signals Monday morning, July 23, indicating its power situation improved slightly during the days when it obeyed commands to refrain from communicating with Earth in order to conserve power. Dust storms on Mars in recent weeks have darkened skies over both Opportunity and its twin, Spirit. The rovers rely on electricity that their solar panels generate from sunlight. By last week, output from Opportunity's solar panels had dropped by about 80 percent from a month earlier.

HiRISE Catches A Dust Devil On Mars

Tucson AZ (SPX) Jul 21, 2007 - The University of Arizona-based High Resolution Imaging Experiment (HiRISE) group this week released a good look at a dust devil on Mars. This is not the storm bedeviling NASA's Mars Exploration Rovers, Spirit and Opportunity. The HiRISE camera captured the dust twister by chance in its photographic swath of a region in the southern hemisphere near Hellas Planitia during a Martian mid-afternoon early last month. The HiRISE camera is orbiting the Red Planet on NASA's Mars Reconnaissance Orbiter.

NASA Robots Practice Moon Survey In The Arctic Circle

Moffett Field CA (SPX) Jul 21, 2007 - Two NASA robots are surveying a rocky, isolated polar desert within a crater in the Arctic Circle. The study will help scientists learn how robots could evaluate potential outposts on the moon or Mars. The robots, K10 Black and K10 Red, carry 3-D laser scanners and ground-penetrating radar. The team arrived at Haughton Crater at Devon Island, Canada, on July 12 and will operate the machines until July 31.

Raytheon Celebrates Math And Science Education On MARS Day

Waltham, MA (SPX) Jul 21, 2007 - Did the Mars Exploration Rovers find evidence of life on the Red planet? How long is a Martian year? Today, nearly 100 Washington area YMCA summer campers, ages 11-13 years, learned the answers to these questions when they teamed with Raytheon for a celebration of the planet Mars. Raytheon, as part of its MathMovesU middle school initiative, is showing young people how engaging math and science can be with a series of Mars-related activities, including hosting the YMCA campers at the Smithsonian National Air and Space Museum's annual MARS Day and recognizing the winner of the national MathMovesU Mission to MARS online math challenge.

Mars Rovers Brave Dust Storms But Outcome Increasingly Grim

Pasadena CA (JPL) Jul 20, 2007 - Having explored Mars for three-and-a-half years in what were missions originally designed for three months, NASA's Mars rovers are facing perhaps their biggest challenge. For nearly a month, a series of severe Martian summer dust storms has affected the rover Opportunity and, to a lesser extent, its companion, Spirit. The dust in the Martian atmosphere over Opportunity has blocked 99 percent of direct sunlight to the rover, leaving only the limited diffuse sky light to power it.

Clay Studies Alter View Of Early Mars Environment

Fayetteville AR (SPX) Jul 19, 2007 - A study of the thermodynamics of clays found on Mars suggests that little carbon dioxide could have been present during their formation, which contradicts a popular theory of the early Martian atmosphere and will send researchers looking for other explanations for clay formation. Vincent Chevrier of the University of Arkansas and Francois Poulet and Jean-Pierre Bibring of the Universite Paris-Sud in Orsay, France, reported their findings in the journal Nature.

Layers Exposed In Crater Near Mawrth Vallis

Tempe AZ (SPX) Jul 19, 2007 - This image covers an impact crater roughly 4 kilometers (2.5 miles) in diameter. The subimage shows just a small segment of the crater rim (1336 x 889; 3 MB). The surface outside the crater (top) is relatively dark, while the interior wall of the crater has a lighter tone. A few dark patches on the crater wall have small dunes or ripples on their surfaces, and are likely pits filled with dark sand.

Hunt For Life On Mars Goes Underground In New NASA Mission

Washington (AFP) Jul 17, 2007 - The hunt for evidence of life on Mars will go underground next year when a NASA probe digs beneath the surface of the red planet's arctic northern plains, US scientists revealed Monday. In a departure from previous missions -- which have seen robotic vehicles explore the planet's hills and craters -- NASA's Phoenix Mars Lander will instead dig into Martian soil for conditions favorable to past or present life.

Opportunity Waiting For Dust To Settle

Pasadena CA (JPL) Jul 17, 2007 - Due to extensive dust storms in Mars' southern hemisphere causing record atmospheric opacity levels, Opportunity is currently experiencing its lowest power levels to date. The tau measurement as of sol 1225 is 4.12, resulting in a mere 280 watt-hours of array energy. A tau measurement of 5.0 would result in approximately 150 watt-hours. If tau begins to approach 5.0, the team will have to begin deleting communications windows in order to conserve energy and keep from draining the batteries.

The Origin Of Perennial Water-Ice At The South Pole Of Mars

Paris, France (ESA) Jul 16, 2007 - Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole. Early during the mission, the OMEGA instrument (Visible and Infrared Mineralogical Mapping Spectrometer) on board Mars Express had already found previously undetected perennial deposits of water-ice. They are sitting on top of million-year old layered terrains and provide strong evidence for a recent glacial activity.

Arizona State Scientists Keep An Eye On Martian Dust Storm

Tempe AZ (SPX) Jul 13, 2007 - Scientists at Arizona State University's Mars Space Flight Center are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a large dust storm on the Red Planet. The instrument, a multi-wavelength camera sensitive to five visible wavelengths and 10 infrared ones, is providing Mars scientists and spacecraft controllers with global maps that track how much atmospheric dust is obscuring the planet.

NASA Readies Mars Lander For August Launch To Icy Site

Washington DC (SPX) Jul 10, 2007 - NASA's next Mars mission will look beneath a frigid arctic landscape for conditions favorable to past or present life. Instead of roving to hills or craters, NASA's Phoenix Mars Lander will claw down into the icy soil of the Red Planet's northern plains. The robot will investigate whether frozen water near the Martian surface might periodically melt enough to sustain a livable environment for microbes. To accomplish that and other key goals, Phoenix will carry a set of advanced research tools never before used on Mars.

An Opportunity For A One-Way Trip To The Bottom Of Crater Victoria

Pasadena CA (JPL) Jul 06, 2007 - NASA's Mars rover Opportunity is scheduled to begin a descent down a rock-paved slope into the Red Planet's massive Victoria Crater. This latest trek carries real risk for the long-lived robotic explorer, but NASA and the Mars Rover science team expect it to provide valuable science. Opportunity already has been exploring layered rocks in cliffs around Victoria Crater. The team has planned the descent carefully to enable an eventual exit, but Opportunity could become trapped inside the crater or lose some capabilities. The rover has operated more than 12 times longer than its originally intended 90 days.

Spirit Independently Approaches And Studies A Rock

Pasadena CA (JPL) Jul 06, 2007 - Spirit remains healthy after attempting to wrap up scientific studies on an outcrop that contains several tantalizing, high-silica targets. High-silica targets are of interest to scientists because water might have been involved in forming them. Spirit still has some work to do on two targets, known as Eileen Dean and Innocent Bystander, before moving on to the elevated, circular plateau known as Home Plate.
