Curiosity Not So Curious

      Jet Propulsion Laboratory (JPL) Pasadena - Curiosity probably has an electrical problem. Curiosity has spent the previous several months driving toward its ultimate destination, Mount Sharp. Nasa restarted the rover's computer system earlier this month, but that is not suspected to be related to the current problem. Curiosity is now in a scheduled safe-mode. The six-wheel, nuclear powered rover halted work as a precaution. Nasa said, a voltage change was first discovered on Sunday, November 17. Engineers think it might be some kind of short circuit.
