In June 2015, Mars will swing almost directly behind the sun from Earth’s perspective, and this celestial geometry will lead to diminished communications with spacecraft at Mars. The arrangement of […]
There was no tape draped across a finish line, but NASA is celebrating a win. The agency’s Mars Exploration Rover Opportunity completed its first Red Planet marathon Tuesday — 26.219 […]
NASA’s Mars Exploration Rover Opportunity is nearing a location on Mars at which its driving distance will surpass the length of a marathon race. A drive on Feb. 8, 2015, […]
With its solar panels their cleanest in years, NASA’s decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of […]
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 […]
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. The shadow falls across a slope […]
A new image from a telescopic camera orbiting Mars shows NASA’s Mars Exploration Rover Opportunity at work on “Murray Ridge,” without any new impact craters nearby. The Feb. 14 view […]
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 […]
New findings from rock samples collected and examined by NASA’s Mars Exploration Rover Opportunity have confirmed an ancient wet environment that was milder and older than the acidic and oxidizing […]
Ten years ago, the Mars Exploration Rovers Spirit and Opportunity landed on Mars. What an adventure it’s been. Though Spirit and Opportunity were built as nearly identical twins, and both […]
Features on Mars important to the missions of NASA’s two active Mars rovers are now called “Murray Ridge” and “Murray Buttes,” in honor of influential planetary scientist Bruce Murray (1931-2013). […]
NASA’s Mars Exploration Rover has begun climbing “Solander Point,” the northern tip of the tallest hill it has encountered in the mission’s nearly 10 Earth years on Mars. Guided by […]
NASA’s Mars rover Opportunity is studying the area of contact between a rock layer formed in acidic wet conditions long ago and an even older one that may be from […]
NASA’s senior Mars rover, Opportunity, is driving to a new study area after a dramatic finish to 20 months on “Cape York” with examination of a rock intensely altered by water. […]
