NASA's Curiosity Mars Rover Approaches 'Cooperstown'
When it drives autonomously, the rover chooses a safe route to designated waypoints by using its onboard computer to analyze stereo images that it takes during pauses in the drive. Prior to Monday, each day’s autonomous drive came after a segment earlier that day that was exactly charted by rover team members using images sent to Earth. The Sunday-Monday drive was the first time Curiosity ended an autonomous driving segment, then continued autonomously from that same point the next day.
The drives brought Curiosity to about 262 feet (about 80 meters) from "Cooperstown," an outcrop bearing candidate targets for examination with instruments on the rover's arm.
