Since 2004, original interviews, original reporting, and the only regularly published news feature documenting NASA’s first overland expedition of the Red Planet through the adventures and discoveries of Opportunity, Spirit, and the MER team, by A.J.S. Rayl.
The autumn skies over Endeavour Crater remained hazy as dust from the summer storms continued to rain down, but Opportunity encountered some unexpected and serious June gloom when her right front steering wheel jammed during the walkabout atop Perseverance Valley.
In another dynamic demonstration of what can be achieved when a team works together, Opportunity cruised to the top of Perseverance Valley, shot the moon, and drove into her 160th month of surface operations in May.
After wrapping the final science investigations on the slopes of Cape Tribulation, Opportunity climbed up and over the rim of Endeavour Crater in March and embarked on the journey south toward its next science target: Perseverance Valley.
Driving the Mars Exploration Rovers (MER) mission further into its fourteenth year of surface operations, Opportunity continued hiking the slopes of Cape Tribulation in February and finally reached the crest of Endeavour Crater’s western rim.
Our 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.
