Mars Exploration Rovers Update

Opportunity drove farther into Marathon Valley in August, dug into what appears to be a water-altered rock, and took a lot of picture postcards in what is turning out to be a distinctively different site from any that the mission has found since the robot field geologist landed in 2004.
Nearly seven Earth years after Opportunity set its sites on Endeavour Crater, the rover cruised into Marathon Valley, the once-but-a-dream destination.
After three weeks of being in a communications blackout on the other side of the Sun during the Earth-Mars solar conjunction, Opportunity phoned home, reporting that she is healthy and ready to continue her mission.
Opportunity spent a mostly merry month of May on Mars touring Spirit of St. Louis Crater, stopping at science targets named in honor of Charles Lindbergh and the incredible flight he took 88 years ago.
After investigating some flat, light and dark toned rocks around Spirit of St. Louis Crater in April, Opportunity chalked up another milestone achievement – the 4000th sol or Martian day of surface operations.
The Mars Exploration Rovers (MER) Update has recorded the journeys of the twin rovers Spirit and Opportunity on the surface of Mars since their arrival in January of 2004. It is a treasure-trove of information, insight, and high-quality reporting detailing every step of this unprecedented voyage of discovery.
