Fig. 1. Curiosity used its arm-mounted camera to take dozens of images at a sandstone drill target called Windjana that were combined into this “selfie.” The view does not include the rover’s arm. Most of the frames of this mosaic view were taken during the 613th Martian day, or sol, after landing (27 April 2014). Frames showing Windjana after completion of the drilling were taken on sol 627 (12 May 2014). Aeolis Mons can be seen in the background. Credit: NASA/JPL-Caltech/MSSS.
