The team operating NASA's Mars Exploration Rover Spirit plans diagnostic tests this week after Spirit did not report some of its weekend activities, including a request to determine its orientation after an incomplete drive. On Sunday, during the 1,800th Martian day, or sol, of what was initially planned as a 90-sol mission on Mars, information radioed from Spirit indicated the rover had received its driving commands for the day but had not moved. That can happen for many reasons, including...

PASADENA, Calif. -- Two weeks after rover Opportunity's robotic arm failed to extend, engineers traced the problem to a stalled motor and fixed it. The mishap happened Nov. 25 when Opportunity tried to unstow its arm to examine a layered outcrop in the Martian plains. But the arm, which carries four tools to chip at rocks and soil, failed to deploy because of a jammed shoulder-joint motor. Engineers zapped current to the motor and it finally moved this week, Jim Erickson, project manager at...

PASADENA, Calif. (AP) -- NASA's Mars rover Opportunity is making progress getting itself unstuck from a sand dune that has left it immobilized the past two weeks, engineers said Monday. Opportunity moved 4.6 centimeters over the weekend after scientists sent the first new driving directions last week, said Mark Maimone, a mobility software engineer at NASA's Jet Propulsion Laboratory. "This is good progress," Maimone said. Opportunity's six wheels starting slipping on April 26 during...

LOS ANGELES (AP) -- The Mars rover Opportunity is facing its biggest challenge since it landed on the Red Planet last year: how to get out of a sand dune where it's been stuck for two weeks. Engineers spent this week simulating the Martian terrain at NASA's Jet Propulsion Laboratory in Pasadena to try to figure out why the robot got bogged down and how to get it moving again. Engineers performed several tests driving a dummy rover over a man-made sand dune. Scientists sent the first new...

JPL -- Mars rover engineers are using a testing laboratory to simulate specific Mars surface conditions where NASA's rover Opportunity has spun its wheels in a small dune. Careful testing is preceding any commands for Opportunity to resume moving to get out of the dune and continue exploring. The rover team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., has cooked up recipes combining various sandy and powdery materials for the best simulation on Earth of the dune where Opportunity...

Word of the Day
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
