Curiosity (rover)

A self-portrait by the Mars rover Curiosity on October 31, 2012. The mosaic is stitched from a set of 55 images taken by the Mars Hand Lens Imager at "Rocknest," the spot in Gale Crater where the mission's first scoop sampling took place. Self-portraits such as this help NASA document the state of the rover and track changes, such as dust accumulation and wheel wear.
