NASA Actively Working to ‘Save Opportunity and LRO’ From Budget Cutters' Axe

Opportunity at Spirit of Saint Louis crater scanning into Marathon Valley and Endeavour crater from current location on Mars in April 2015 in this photo mosaic. The crater, featuring an odd mound of rocks, is the gateway to Marathon Valley and exposures of water altered clay minerals. This pancam camera photo mosaic was assembled […]

Curiosity Discovers Biochemically Accessible Nitrogen, Key Ingredient Needed for Martian Life

Curiosity detected biochemically accessible nitrogen here at John Klein drill site! Curiosity accomplished historic first drilling into Martian rock at John Klein outcrop on Feb 8, 2013 (Sol 182), and discovered a habitable zone, shown in this context mosaic view of the Yellowknife Bay basin taken on Jan. 26 (Sol 169). The robotic arm […]

Opportunity Achieves Marathon Distance Feat at Majestic Mars Mountain Overlook

View from Opportunity on Mars today! Opportunity’s view on the day the NASA rover exceeded the distance of a marathon on the surface of Mars on March 24, 2015, Sol 3968. Rover stands at Spirit of Saint Louis crater near mountaintop at Marathon Valley overlook and Martian cliffs at Endeavour crater holding deposits of […]

Whoa! Opportunity Discovers Matchless Purplish Rocks at Spectacular Mars Overlook

NASA’s Opportunity Rover scans along a spectacular overlook towards Marathon Valley on March 3, 2015, showing flat-faced rocks exhibiting a completely new composition from others examined earlier. Marathon Valley and Martian cliffs on Endeavour crater hold deposits of water altered clay minerals. This navcam camera photo mosaic was assembled from images taken on Sol […]

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.
