Mystery Phenomenon Cleans Mars Opportunity Rover

vg30e writes "It seems that some unexplained phenomenon has cleaned the dirt off the Mars Opportunity Rover. While the Spirit rover is down to 400 watt-hours per day due to the dirt obscuring its solar panels, Opportunity has gone from 500 watt-hours to 900 per day. I wish this phenomenon would clean the snow off my car."

    Why don't you fucking google it? Your question has been asked dozens of times in the comments to EVERY fucking slashdot article about the Mars rovers, and there's been a lot of them. Did you really imagine you were the first person to ask this question?
