Sandtrapped Rover Makes A Big DiscoveryHuntsville AL (SPX) Dec 04, 2009 Homer's Iliad tells the story of Troy, a city besieged by the Greeks in the Trojan War. Today, a lone robot sits besieged in the sands of Troy while engineers and scientists plot its escape. Welcome to "Troy" - Mars style. NASA's robotic rover Spirit is bogged down on the Red Planet in a place the rover team named after the ancient city. So why aren't scientists lamenting? "The rover's spinning wheels have broken through a crust, and we've found something supremely interesting in the disturbed soil," says Ray Arvidson of the Washington University in St. Louis. ... read more |

Pasadena CA (SPX) Nov 26, 2009On Sol 2095 (Tuesday, Nov. 24), Spirit performed a set of diagnostic actions related to a stall of the right-rear wheel on the previous drive, three days earlier. The diagnostics showed a fully functioning wheel free of obstruction. The rover was commanded forward with 1.5 meters (4.9 feet) of wheel spin. The rover moved 2.1 millimeters (0.08 inch) forward, 1.1 millimeters (0.04 inch) to ... more 
Pasadena CA (SPX) Nov 26, 2009The team operating NASA's Mars Reconnaissance Orbiter plans to uplink protective files to the spacecraft next week as one step toward resuming the orbiter's research and relay activities. Since the orbiter spontaneously rebooted its computer on Aug. 26, flight team engineers have been examining possible root causes and repercussions of that incident and three similar events this year on ... more 
Washington (AFP) Nov 23, 2009A network of valleys discovered on Mars show that the red planet was likely once covered by a vast ocean that fed a humid, rainy climate, according to research published Monday. Debate has raged for decades over whether Martian valleys resulted from water erosion - caused by humidity and rainfall - or through groundwater-sapping erosion, which can happen in cold and dry conditions. ... more |

Pasadena CA (SPX) Nov 18, 2009Driving commands are being prepared to instruct Spirit to attempt to drive forward. These are the first driving commands since Spirit became embedded in a Martian sandtrap approximately six months ago. These commands will be transmitted to Spirit at 1 a.m. PST (4 a.m. EST) Tuesday, Nov. 17. The rover will be instructed to drive straight ahead (north) in two steps. Each step will be a comma ... more 
Pasadena CA (SPX) Nov 18, 2009NASA and Microsoft Corp. of Redmond, Wash., have collaborated to create a Web site where Internet users can have fun while advancing their knowledge of Mars. Drawing on observations from NASA's Mars missions, the "Be a Martian" Web site will enable the public to participate as citizen scientists to improve Martian maps, take part in research tasks, and assist Mars science teams studying da ... more 
Pasadena CA (SPX) Nov 17, 2009Opportunity is still heading south before the turn east to head toward Endeavour Crater. The right front wheel is exhibiting elevated motor currents. So, the plan is to find a place to stop and rest the actuator while conducting some some contact science. On Sol 2058 (Nov. 7, 2009), the rover began a 15-meter (49-foot) approach to a candidate rock target called "Marquette Island." On ... more |
