Spirit problems still baffle scientists
Washington, April 27, 2009 U.S. space agency scientists say they have not yet solved the mysterious cause of several glitches in the Mars exploration rover Spirit. National Aeronautics and Space Administration engineers remotely drove Spirit Thursday for the first time since April 8 while investigating bouts of amnesia and other unusual behavior exhibited by the rover this month. Spirit has already operate ... more Spirit Resumes Driving While Analysis Of Problem Behaviors Continues 
Pasadena CA (JPL) Apr 27, 2009NASA's Mars Exploration Rover Spirit drove on Thursday for the first time since April 8, acting on commands from engineers who are still investigating bouts of amnesia and other unusual behavior exhibited by Spirit in the past two weeks. The drive took Spirit about 1.7 meters (5.6 feet) toward destinations about 150 meters (about 500 feet) away. The rover has already operated more than 20 ... more Bone-Density Monitor Would Let Astronauts Test While In Space 
Houston TX (SPX) Apr 24, 2009It would be terrible if the first humans to reach Mars stepped onto the surface to discover their legs could no longer hold them. A team of Rice University students is working to make sure that doesn't happen. Five senior bioengineering students have designed a device to help astronauts keep their skeletons strong and healthy by measuring bone mineral density loss, literally on the fly. ... more Early Martian Environment And Water Drive Search For Life Forms 
New Rochelle (SPX) Apr 17, 2009Solar energy and winds, collisions with asteroids and comets, and changing magnetic fields have all altered the environment of Mars, a planet that may have been able to support life during its history, as documented in a special collection of papers published in the current issue of Astrobiology, a peer-reviewed journal published by Mary Ann Liebert, Inc. Compiled by Helmut Lammer, PhD, Se ... more Mars Science Laboratory Parachute Qualification Testing 
Moffett Field CA (SPX) Apr 17, 2009The parachute for NASA's Mars Science Laboratory passed flight-qualification testing in March and April 2009 inside the world's largest wind tunnel, at NASA Ames Research Center, Moffett Field, Calif. In this image, an engineer is dwarfed by the parachute, the largest ever built to fly on an extraterrestrial flight. It is designed to survive deployment at Mach 2.2 in the Martian atmosphere ... more |

Canoga Park CA (SPX) Apr 08, 2009Pratt and Whitney Rocketdyne completed a series of successful hot-fire tests for a propulsion system that could lead to increased mission capability and flexibility in sending humans to the moon, Mars and beyond. During the tests at NASA's Glenn Research Center in Cleveland, Ohio, a 25 pound-force thruster testbed successfully demonstrated cooling with gaseous methane and gaseous oxygen, a ... more Spirit Sets Distance Record For Five-Wheel Driving 
Pasadena CA (SPX) Apr 04, 2009Spirit is making good progress around Home Plate to the west. After getting clear of troublesome rocks, Spirit drove 13.8 meters (45.3 feet) on Sol 1854 (March 21, 2009). The next drive, on Sol 1856 (March 23, 2009) , achieved a new distance record for five-wheel driving. Spirit drove 25.82 meters (84.7 feet), beating the old record by about a meter. Spirit completed another drive of ... more Opportunity Brushing and Examining an Outcrop 
Pasadena CA (SPX) Apr 04, 2009Opportunity remains positioned on an exposed rock outcrop, continuing an "in situ" (contact) science campaign with the robotic arm (IDD). On Sol 1832 (March 20, 2009), the first part of a rock abrasion tool (RAT) brushing activity was performed. Using a new work-around for the failed RAT Z-encoder, the RAT successfully performed a seek-scan to locate the rock surface. On the next sol ... more Bright Soil Churned By Spirit's Sol 1861 Drive 
Pasadena CA (SPX) Apr 02, 2009NASA's Mars Exploration Rover Spirit drove 22.7 meters (74 feet) toward the southwest on the 1,861st Martian day, or sol, of Spirit's mission on Mars (March 28, 2009). After the drive, the rover took this image with its front hazard-avoidance camera, looking back at the tracks from the drive. As usual since losing the use of its right-front wheel in 2006, Spirit drove backwards. The ... more |

Huntsville AL (SPX) Mar 27, 2009In January 2004, NASA landed two identical robotic rovers named Spirit and Opportunity on the surface of Mars. The twins were primed for a brief 3-month mission to tell us a story of water and possibly life itself in the planet's past. More than five years later, the dynamic duo are still roving the Red Planet, engaged in a saga of overachievement that has transformed Mars exploration. ... more Welcome To The Red Planet 
Moffett Field CA (SPX) Mar 27, 2009Did you ever wish you could stroll through the caldera of Olympus Mons, the largest volcano in the solar system? Study the rock formations in Valles Marineris, a martian canyon as wide as the United States? Or retrace the tracks of NASA's Spirit and Opportunity rovers? Then you'll want to check out Google Mars. Tucked away inside the recently released Google Earth 5.0, Google Mars is the i ... more Opportunity At Outcrop - Endeavour In Sight - Sol 1824-1831 
Pasadena CA (SPX) Mar 26, 2009Opportunity has positioned itself at an exposed rock outcrop and is in the middle of an "in situ" (contact) science campaign with the robotic arm (IDD). Because of the project team's desire to rest the right-front wheel actuator and to limit driving while an earlier drive sequence error is remedied, Opportunity took advantage of the nearby rock outcrop. This fits with the strategic science ... more Discovery astronauts complete final spacewalk 
Washington (AFP) March 23, 2009Discovery astronauts ended their third and final spacewalk on Monday on a slight down note, unable to fix a jammed cargo carrier system, NASA said. Richard Arnold and Joseph Acaba, two former science teachers turned astronauts, carried out a six-and-a-half hour walk in space, which included attempts to unblock the external cargo carrier. The carrier became stuck after Acaba and another ... more
