Mars Exploration Rovers Update
As the Mars Exploration Rover (MER) team waited out solar conjunction, Opportunity spent most of April atop the western rim of Endeavour Crater, conducting a chemical analysis of an ancient waterborne vein on Matijevic Hill. It was by the book until the last week of the month when the robot field geologist suffered an electronic "hiccup" known as a warm re-boot, and went into auto mode, a kind of safe mode when something doesn't go right.
As the Mars Exploration Rover (MER) mission trekked further into its tenth year of exploring the Red Planet, Opportunity spent the month of March finishing up its science investigations on Matijevic Hill.
As February turned to March, Opportunity was conducting some of its final science investigations on Matijevic Hill, the MER team was making preparations for the robot field geologist's trek south for the next winter, and the Mars Exploration Rovers mission was checking off another month of exploration.
With its robot nose to the Martian grindstone, Opportunity completed its ninth year of working on Mars in January, making another significant science discovery in tiny white veins on Matijevic Hill as the Mars Exploration Rover (MER) mission rolled on into Year 10.
Despite the lull of the holidays, the Mars Exploration Rover (MER) mission recorded one of the expedition's best months ever in December as Opportunity and her team confirmed the location of the smectite clay minerals on Matijevic Hill, effectively grabbing the scientific brass ring they came hoping to find at Endeavour Crater.
The Mars Exploration Rovers (MER) Update have followed the twin rovers Spirit and Opportunity since the beginning of their mission in January of 2003. They are a treasure-trove of information, insight, and high-quality reporting detailing every step of the mission on a monthly basis written by experienced journalist A.J.S. Rayl.
