Opportunity Tops Martian Mountain! Milestone Achievement 11 Years After Touchdown Reveals Stunning Vista

Stunning new mountain top vista from NASA’s Opportunity rover after reaching summit of Cape Tribulation in January 2015 nearly 11 years after Martian touchdown. Panoramic scene shows vast expanse of Endeavour Crater from highest mountain rover will ever climb. See crater rim expanding out from center and rover solar panels at right and wheel tracks […]

Opportunity Nears Highest Ever Mountain Peak of Astounding 11-Year Martian Trek

NASA’s Opportunity Mars rover scans to the summit of Cape Tribulation less than 100 meters distant in mid-December 2014. Beyond lie caches of clay minerals. The scene shows impact breccias and thin soil cover with cobbles over bedrock. This navcam camera photo mosaic was assembled from images taken on Sol 3871, Dec. 13, 2014, […]

NASA Curiosity Rover Discovers Methane and Organics on Mars

This image illustrates possible ways methane might be added to Mars’ atmosphere (sources) and removed from the atmosphere (sinks). NASA’s Curiosity Mars rover has detected fluctuations in methane concentration in the atmosphere, implying both types of activity occur on modern Mars.
