wind sensor fault
quote: "One possibility is that pebbles lofted during the landing hit the delicate circuit boards on one of the two REMS booms," said Curiosity deputy project scientist Ashwin Vasavada.
When I saw one of the first pics showing the top of Curiosity, my first thought was "There's a load of unprotected wires on the top there".....and other reports of the sensor fault claim it might be down to "cut wires"....
Given the method of landing meant a lot of surface material was going to be thrown up the the Sky Crane, you'd have thought that someone would have ensured that these wires were protected. I also wonder if these exposed wires have good enough "outdoor" properties to protect them against heat/cold etc.
