Mars rovers begin to stir as dust storms recede
Lofting dust high in the atmosphere, the storms blocked precious sunlight needed for the rover solar panels to generate power. Both rovers had to stop driving, and Opportunity was so starved of power that its handlers worried it might freeze to death during the cold Martian night. Now, the storms have finally receded and both rovers are about to start driving towards much-anticipated targets.
…
Opportunity is getting about 300 watt-hours of energy per day, more than twice the level it was getting during the worst part of the storms. But it is still not enough to start the descent into the crater, Arvidson says: “We want to make sure if we have some mobility problems that there’s energy to spare to get out of the problem areas.”
These rovers just keep going. From a NASA press release last October: “NASA’s long-lived Mars Exploration Rover Spirit will finish its 1,000th Martian day Thursday, continuing a successful mission originally planned for 90 Martian days.”
