Image 1 - Researchers Take Temperature Of Mars's Past
2011-10-13 04:19:02

Researchers at the California Institute of Technology (Caltech) have directly determined the surface temperature of early Mars for the first time, providing evidence that's consistent with a warmer and wetter Martian past. By analyzing carbonate minerals in a four-billion-year-old meteorite that originated near the surface of Mars, the scientists determined that the minerals formed at about 18 degrees Celsius (64 degrees Fahrenheit). "The thing that's really cool is that 18 degrees is not...

Video Documents Mars Rover's Three-Year Trek
2011-10-11 04:04:12

[ Watch the Video ] While NASA's Mars Exploration Rover Opportunity was traveling from Victoria crater to Endeavour crater, between September 2008 and August 2011, the rover team took an end-of-drive image on each Martian day that included a drive. A new video compiles these 309 images, providing an historic record of the three-year trek that totaled about 13 miles (21 kilometers) across a Martian plain pocked with smaller craters. The video shows the rim of Endeavour becoming visible...

Mars Rovers Named A Popular Mechanics 'Breakthrough'
2011-10-03 14:54:13

More than seven years after completing their three-month prime missions on opposite sides of Mars, NASA rovers Spirit and Opportunity have been selected for lifetime achievement award honors as part of the Breakthrough Awards presented by Popular Mechanics magazine. The magazine today announced recipients of awards to be presented Oct. 10 in New York. The announcement cites the Mars rovers' engineers, as well as the robots themselves, "for overcoming great challenges in their dogged...

  Mars rover poised on rock that may yield yet more evidence of a wet Mars Shortly after Labor Day 2011, the Mars rover Opportunity was poised on the rim of the 22,000 meter-wide Endeavour Crater, preparing to sample a novel rock type. Much older than the sedimentary samples the rover´s “tasted” so far, this new sample is flush with the promise of revealing clues to the planet´s environment when running rivers coursed the surface. What was supposed to have...

Mars Memorial Image Taken September 11, 2011

  A view of a memorial to victims of the Sept. 11, 2001, attacks on the World Trade Center towers was taken on Mars yesterday, on the 10th anniversary of the attacks. The memorial, made from aluminum recovered from the site of the twin towers in weeks following the attacks, serves as a cable guard on a tool on NASA's Mars Exploration Rover Opportunity and bears an image of the American flag. The memorial is on the rover's rock abrasion tool, which was being made in September...

Mars Rovers Carry 9/11 Tributes
2011-09-09 06:25:16

  In September 2001, Honeybee Robotics employees in lower Manhattan were building a pair of tools for grinding weathered rinds off rocks on Mars, so that scientific instruments on NASA's Mars Exploration Rovers Spirit and Opportunity could inspect the rocks' interiors. That month's attack on the twin towers of the World Trade Center, less than a mile away, shook the lives of the employees and millions of others. Work on the rock abrasion tools needed to meet a tight schedule to...

Image 1 - Mars Rover Studying New Areas Of Martian Surface
2011-09-01 14:45:22

  NASA said on Thursday that its Opportunity rover has started to study Martian surface composition from its new location. Opportunity arrived earlier in August at the rim of a 14-mile-wide crater named Endeavour.  The first rock examined by the rover was flat-topped and about the size of a footstool, according to NASA. "This is different from any rock ever seen on Mars," Steve Squyres, principal investigator for Opportunity at Cornell University in Ithaca, N.Y., said in a...

NASA will host a media teleconference on Thursday, Sept. 1, at 12:30 p.m. PDT to discuss progress of NASA's Mars Exploration Rover Opportunity. Opportunity reached the Martian Endeavour crater earlier this month after years of driving. The teleconference participants are: -- Dave Lavery, program executive, Mars Exploration Rovers, NASA Headquarters, Washington -- Steve Squyres, principal investigator, Mars Exploration Rovers, Cornell University, Ithaca, N.Y. -- Ray Arvidson,...

Mars' Moon Deimos -- outermost of two small moons orbiting the planet Mars. Deimos orbits Mars at a distance of about 23,500 km (about 14,100 mi), completing an orbit once every 1.26 Earth days. The moon's orbit is almost circular and is only slightly tilted relative to the Martian equator. Deimos is irregular in shape, measuring about 15 km (about 9 mi) along its longest side and about 11 km (about 6.6 mi) along its shortest side. It is the smallest known moon in the solar system. If...

Mars' Moon Phobos -- in astronomy, innermost moon, or natural satellite, of Mars. Phobos orbits Mars at a distance of only 9,378 km (5,627 mi), closer to its planet than any other moon in the solar system. In fact, it is so close that the force of Mars's gravity is stronger than the force keeping the moon in its orbit, so the radius of Phobos's orbit is decreasing at the rate of about 1.8 m (about 6 ft) per century. In 40 million years, Phobos will either break apart into a ring...
