article_snippet: A short circuit has temporarily rendered Nasa's Curiosity rover  inactive as engineers investigate an electrical problem.
article_snippet: the rover stopped work when an electrical problem was discovered while the rover was using the rover arm to move powder into the rover sample container.
article_snippet: The severity of an electrical problem is not yet known, but Nasa said Nasa expected to resume operations in several days if it can be resolved.
article_snippet: A short circuit occurred in the rover's arm as the rover's arm was moving.
article_snippet: The short circuit occurred while the rover was moving the rover's arm on 27 February.
article_snippet: When the rover detected the anomaly, the rover stopped the movement of the rover's arm.
article_snippet: Nasa said that such a brief short could have little effect on rover operations, or it 'could prompt the rover team to restrict use of a mechanism'.
article_snippet: The fault occurred while the rover had been transferring rock powder collected by the rover drill on the rover's arm to laboratory instruments on the rover.
article_snippet: The fault occurred while the rover had been transferring rock powder collected by its drill on the arm to laboratory instruments on the roverits drill on the arm .
article_snippet: Three days later, a fault-protection action by the rover halted a process of transferring sample powder that was collected during this drilling .
article_snippet: the rover has successfully analysed four drill samples before, but has not yet experienced this short circuit failure .
