Good News from Mars

Filed under: — Different River @ 1:53 am

The Mars Exploration Rovers Spirit and Opportunity landed on Mars over a year ago, on January 3 and January 24, 2004, respectively. They were designed to last through 90 days of taking scientific measurements, but it’s been 436 days and 457 days now, and they’re both going strong.

Or were — until Spirit’s solar panels started to get covered with dust and the power output declined. But now, as Bird’s Eye View explains, things are going fine again. Amazing. (And no, they didn’t put windshield wipers on the solar panels. They probably should next time, though!)
