Sols 3800 - 3829

As winds whirled and converged to the west of Endeavour Crater, Opportunity's power dropped dramatically in October, but the Mars Exploration Rover (MER) pressed on. By month's end, the robot field geologist had completed her assignments – including capturing the first close-in shot of a comet from the surface of the Red Planet – and was roving onward through the darkness, driving the mission into the 130th month of what started out more than 10-and-a-half years ago to be a 3-month tour.

Mars Exploration Rovers Update: Opportunity Gets Extension, Returns Killer Panoramas, and Roves onto Mystery Rocks
Sols 3770 - 3799

Posted by A.J.S. Rayl on 2014/10/04 10:15 CDT | 1 comments

While the winds of Martian spring blew through Meridiani Planum in September, Opportunity reformatted its Flash memory then continued exploring Wdowiak Ridge on the western rim of Endeavour Crater. Even though the Flash-related issues soon returned, the robot field geologist hardly seemed to notice as it sent home two spectacular panoramas, presented the scientists with a rocky Martian mystery, and delivered yet another September to remember for the mission. And that's not all.
