Mars Exploration Rovers Update
On January 24th, the veteran Mars Exploration Rover (MER) wrapped the last day of her 12th year of surface operations on Mars, marking an extraordinary, historic achievement for the Mars Exploration Rovers (MER) mission.
Perched on the southern wall of Marathon Valley at Endeavour Crater, Opportunity braved temperatures descending well below -100° F in December to work the winter science campaign and home in on the remnants of ancient clays.

Opportunity faced the challenges of winter as well as technological issues in November, but pressed on, hiking up hill and into a geological treasure trove that may well present the scientists with the evidence they need to solve the clay mineral mystery of Marathon Valley.

Opportunity hit the slopes of her seventh winter haven on the south side of Marathon Valley in October as the mission entered the 130th month of what was initially slated to be a 90-day tour.
Opportunity continued her walkabout around Marathon Valley in September and sent home more evidence of significant water alteration and, perhaps, an ancient environment inviting enough for the emergence of life.
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.
