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

A.J.S. Rayl • October 04, 2014

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.
