Curiosity update: One Mars Year! Sols 662-670

Emily Lakdawalla • June 25, 2014

On Monday JPL put out a press release marking one year since Curiosity landed -- one Mars year, that is! There was a new version of the Kimberley self-portrait, and a video update on wheel wear testing. While we've been celebrating on Earth, Curiosity has been driving, driving, driving, on a new "safe transit route" taking her southward toward the black sand dunes ringing Mount Sharp.

Curiosity update, sols 645-661: Driving, driving, driving

Eight of the last 14 sols have seen drives ranging in length from 30 to 104 meters, racking up a total of more than half a kilometer. They are now occasionally working a shortened planning timeline that allows them to squeeze more drive sols into Curiosity's schedule.
