For the first time since arriving on Mars engineers have allowed Curiosity to drive itself.

The 1-ton Curiosity rover used autonomous navigation for the first time on Tuesday (Aug. 27), driving itself onto a patch of ground that its handlers had not vetted in advance. The robot will likely employ this “autonav” capability more and more as it continues the long trek toward the base of Mars’ huge Mount Sharp, NASA officials said.

In autonav mode, Curiosity analyzes photos it takes during a drive to map out a safe route forward. The car-size rover used this ability on Tuesday to find its way across a small depression whose fine-scale features were hidden from Curiosity’s previous location.
