Short Circuit Sidelines Curiosity’s Movements After Drilling at Telegraph Peak

This March 6, 2015 (Sol 917), mosaic of images from the Navcam camera on NASA’s Curiosity Mars rover shows the position in which the rover held its arm for several days after a transient short circuit triggered onboard fault-protection programming to halt arm activities on Feb. 27, 2015, Sol 911. The rover team chose […]
