Rear Wheel Trouble Continues For Mars Rover SpiritPasadena CA (JPL) Dec 11, 2009 Results of diagnostic tests on Spirit's right-rear wheel on Sol 2109 (Dec. 8, 2009) continue to indicate a troubled wheel, which may leave the rover with only four operable wheels. The Sol 2109 plan included a check of the grind motor of Spirit's rock abrasion tool (RAT) because it shares the same motor controller as the right-rear wheel. It also included rotor resistance tests on th ... read more |

Pasadena CA (SPX) Dec 08, 2009Opportunity Status for sol 2076-2079: Opportunity has been investigating the rock known as "Marquette Island." On Sol 2076 (Nov. 25, 2009), the robotic arm (IDD) placed the Moessbauer (MB) spectrometer on a rock target called "Islington Bay" for a long, multi-sol integration. With the temporary loss of relay operations for a few sols because of the Odyssey spacecraft safe-mode, Opportunity ... more 
Spirit Status for sol 2096-2099: Spirit's extrication from her embedded location at Troy on the west side of Home Plate has been complicated by a recurring stall condition with the right rear wheel. After diagnostic tests on Sol 2095 (Nov. 24, 2009), indicated a freely moving wheel, another two-step drive with 5 meters (16 feet) of wheel spin was commanded on Sol 2099 (Nov. 28, 2009). ... more  
Bangalore, India (PTI) Dec 07, 2009India's first science satellite Astrosat is all set to be launched next year, former chairman of Indian Space Research Organisation (ISRO) Madhavan Nair said. One more satellite 'Aditya' to study Sun's coronal mass ejection (CME) would be launched in two years while the science mission to planet Mars by 2013, Nair said, addressing a galaxy of scientists from India and abroad and the ... more |

Pasadena CA (SPX) Dec 01, 2009Opportunity has been investigating the rock known as "Marquette Island" over the last couple of weeks. This target is proving to be something unique that Opportunity has not encountered in more than 2000 Sols of exploring Mars. The science team is theorizing this rock could be either be a type of meteorite that Opportunity has never seen before or it could be ejecta from deep within the ... more 
Pasadena CA (SPX) Nov 26, 2009This image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter shows a sample of the variety and complexity of processes that may occur on the walls of Martian craters, well after the impact crater formed. At the very top of the image is the high crater rim. At the bottom of the image is the crater's central peak, a dome of material ... 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 |
