NASA's Mars Curiosity Rover Martian Solar Day 177: Curiosity Rover's Self Portrait at “John Klein“ Drilling Site This panorama combines 66 exposures taken by the rover's Mars Hand Lens Imager (MAHLI) during the Sol 177 of Curiosity's work on Mars (February 3, 2013) The rover is positioned at a patch of flat outcrop called “John Klein“, which was selected as the site for the first rock-drilling activities by Curiosity. The self-portrait was acquired to document the drilling site. The rover's robotic arm is not visible in the mosaic. MAHLI, which took the component images for this mosaic, is mounted on a turret at the end of the arm.
