"Nasa has reported its first setback in the Curiosity rover mission to Mars." A sensor on the robot's weather station that takes wind readings has sustained damage. The mission team stresses this is not a major problem and will merely degrade some measurements - not prevent them. It is not certain how the damage occurred but engineers suspect surface stones thrown up during Curiosity's rocket-powered landing may have struck sensor circuits and broken the wiring." ???
