In its sixth Martian winter, NASA's Mars Exploration Rover Opportunity now has cleaner solar arrays than in any Martian winter since its first on the Red Planet, in 2005. Cleaning effects of wind events in March boosted the amount of electricity available for the rover's work.
Late afternoon lighting produced a dramatic shadow of NASA's Mars Exploration Rover Opportunity photographed by the rover's rear hazard-avoidance camera on March 20, 2014.
Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA's Curiosity Mars rover and could be a study topic at the mission's next science waypoint.
Researchers have determined the now-infamous Martian rock resembling a jelly doughnut, dubbed Pinnacle Island, is a piece of a larger rock broken and moved by the wheel of NASA's Mars Exploration Rover Opportunity in early January.
NASA's Curiosity Mars rover reached the edge of a dune on Jan. 30 and photographed the valley on the other side, to aid assessment of whether to cross the dune.
The team operating NASA's Mars rover Curiosity is considering a path across a small sand dune to reach a favorable route to science destinations. A favorable route would skirt some terrain with sharp rocks considered more likely to poke holes in the rover's aluminum wheels.
NASA has received 58 proposals for science and exploration technology instruments to fly aboard the agency's next Mars rover in 2020, twice the usual number submitted for instrument competitions in the recent past, and an indicator of the extraordinary interest in exploration of the Red Planet.
NASA's Curiosity Mars rover and its recent tracks from driving in Gale Crater appear in an image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Dec. 11, 2013.
Eighth graders didn't have Facebook or Twitter to share news back then, in January 2004. Bekah Sosland, 14 at the time, learned about a NASA rover landing on Mars when the bouncing-ball video on the next morning's Channel One news in her Fredericksburg, Texas, classroom caught her eye.
Science observations by NASA's Mars rover Curiosity have been suspended for a few days while engineers run tests to check possible causes of a voltage change detected on Nov. 17.
Earlier this week, NASA's Mars Exploration Rover began climbing "Solander Point," the northern tip of the tallest hill it has encountered in the mission's nearly 10 Earth years on Mars.
NASA's Mars rover Curiosity has resumed a trek of many months toward its mountain-slope destination, Mount Sharp. The rover used instruments on its arm last week to inspect rocks at its first waypoint along the route inside Gale Crater.
The location, originally chosen on the basis of images taken from NASA's Mars Reconnaissance Orbiter, paid off with investigation of targets that bear evidence of ancient wet environments.
Smart as the Mars Curiosity mission has been about landing and finding its own way on a distant world, the rover is pretty brainless when it comes to doing the science that it was sent 567 million kilometers to carry out. That has to change if future rover missions are to make discoveries further out in the solar system, scientists say.
The latest drive by NASA's Curiosity Mars rover brought the total distance that the rover has driven on Mars to more than 1 kilometer. One kilometer is about 0.62 miles.
NASA's Mars Exploration Rover Opportunity has driven more than half of the distance needed to get from a site where it spent 22 months to its next destination.
Approaching its 10th anniversary of leaving Earth, NASA's Mars Exploration Rover Opportunity is on the move again, trekking to a new study area still many weeks away.
Mars may have lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate.
NASA's released a new, stunning self-portrait of the Curiosity Mars rover, stitched together from dozens of high-resolution images.
NASA is making ambitious plans to land a second rover on Mars in 2020 and send astronauts there in the 2030s.
NASA's confirmed rumors that the Curiosity rover has found organic compounds on Mars - but says they're probably not a sign of life, and likely came from Earth.
