NASA Update Will Deal With Opportunity Flash Memory "Amnesia" 52

BarbaraHudson writes Computerworld has some details on NASA's latest fix to allow the Opportunity Mars Rover to store data while in overnight "sleep mode." Opportunity has been suffering from a glitch that's causing what NASA scientists describe as memory and data loss — or robotic "amnesia" — caused by flash memory deterioration since early December. Currently any information gathered is stored temporarily in RAM and must be sent to Earth so it's not lost when Opportunity powers down.

ESA Shows Off Quadcopter Landing Concept For Mars Rovers 104

coondoggie writes Taking a page from NASA's rocket powered landing craft from its most recent Mars landing mission, the European Space Agency is showing off a quadcopter that the organization says can steer itself to smoothly lower a rover onto a safe patch of the rocky Martian surface. The ESA said its dropship, known as the StarTiger's Dropter is indeed a customized quadcopter drone that uses a GPS, camera and inertial systems to fly into position, where it then switches to vision-based navigation supplemented by a laser range-finder and barometer to lower and land a rover autonomously.

Mars Rover Finds Complex Chemicals But No Organic Compounds 137

techtech writes in with the results from the first soil samples tested by the Curiosity rover. "Although NASA's Curiosity rover hasn't yet confirmed the detection of organic compounds on Mars, it's already seeing that the Red Planet's soil contains complex chemicals — including signs of an intriguing compound called perchlorate. The first soil sample analysis from Curiosity's Sample Analysis at Mars lab, or SAM, was the leadoff topic today at the American Geophysical Union's fall meeting in San Francisco. The findings were eagerly awaited because of rumors that the Curiosity team was on the verge of announcing major findings — and although NASA tamped down expectations, the scientists said they were overjoyed with the first round of analysis."
