Virtually alone in the Martian landscape, NASA’s Mars rover Curiosity has no one to turn to if it gets into trouble. As NASA puts it: “There are no mechanics on Mars, so the next best thing for [a] rover is careful driving.” So in June 2017, NASA engineers deployed a traction-control algorithm they uploaded to Curiosity. The software uses real-time data to adjust each wheel’s speed and reduce pressure from the rocky ground.Mar.08.2018
