  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's Mars Exploration Rover Opportunity has driven over 20 miles in seven years, which is over 50 times the mission's original distance goal. NASA said the rover completed a 407-foot drive on July 17 that took Opportunity past the 20-mile mark.  The drive brought Opportunity to within a few drives of reaching the rim of Endeavour crater, which is the rover team's long-term destination since mid-2008. The crater is about 14-miles in diameter, and its western rim exposes outcrops that...

When NASA's Opportunity Mars rover uses an onboard navigation capability during backward drives, it leaves a distinctive pattern in the wheel tracks visible on the Martian ground. The rover team routinely commands Opportunity to drive backward as a precaution for extending the life of the rover's right-front wheel, which has been drawing more electrical current than the other five wheels. Rover drivers can command the rover to check for potential hazards in the drive direction, whether the...

When NASA's Mars Exploration Rover Opportunity left Victoria Crater two years ago this month, the rover science team chose Endeavour Crater as the rover's next long-term destination. With a drive of 111 meters (364 feet) on Monday, Sept. 8, Opportunity reached the estimated halfway point of the approximately 19-kilometer (11.8-mile) journey from Victoria to the western rim of Endeavour. Opportunity completed its three-month prime mission on Mars in April 2004. During its bonus extended...

NASA's Mars Exploration Rover Opportunity today surpassed 20 kilometers (12.43 miles) of total driving since it landed on Mars 74 months ago. The drive taking the rover past that total covered 67 meters (220 feet) southward as part of the rover's long-term trek toward Endeavour Crater to the southeast. It was on the 2,191st Martian day, or sol, of the mission and brought Opportunity's total odometry to 20.0433 kilometers. To reach Endeavour, the healthy but aging rover will need to drive...

NASA's Mars Exploration Rover Opportunity, now in its seventh year on Mars, has a new capability to make its own choices about whether to make additional observations of rocks that it spots on arrival at a new location. Software uploaded this winter is the latest example of NASA taking advantage of the twin Mars rovers' unanticipated longevity for real Martian test drives of advances made in robotic autonomy for future missions. Now, Opportunity's computer can examine images that the rover...

Because the first extrication drive for Spirit, on Sol 2088 (Nov. 17), stopped as soon as it began due to an exceeded tilt limit, the plan for an extrication drive on Sol 2090 (Nov. 19) will essentially be a repeat of the first drive plan, but with improved rover attitude knowledge. The updated attitude knowledge comes from the rover's measurement of its tilt on Sol 2088. In the Sol 2090 plan, the rover will be instructed to drive straight ahead in two steps. Each step will be a commanded...

NASA will begin transmitting commands to its Mars exploration rover Spirit on Monday as part of an escape plan to free the venerable robot from its Martian sand trap. Spirit has been lodged at a site scientists call "Troy" since April 23. Researchers expect the extraction process to be long and the outcome uncertain based on tests here on Earth this spring that simulated conditions at the Martian site. "This is going to be a lengthy process, and there's a high probability attempts to free...

A second, lighter-weight test rover has entered the testing setup at JPL where rover team members are assessing strategy for getting Spirit out of soft soil where it is embedded on Mars. The rover team has begun using a test rover that does not carry a science payload or robotic arm, as do Spirit and Opportunity on Mars, and the primary engineering test rover at JPL. While the primary test rover's weight on Earth is greater than Spirit's weight on Mars, the second rover is even lighter on...

After three days of completing Earth-commanded activities without incident last week, NASA's Mars Exploration Rover Spirit had a bout of temporary amnesia Friday, April 17, and rebooted its computer Saturday, April 18, behavior similar to events about a week earlier. Engineers operating Spirit are investigating the reboots and the possibly unrelated amnesia events, in which Spirit unexpectedly fails to record data into the type of memory, called flash, where information is preserved even when...
