This self-portrait by the NASA Curiosity rover on the surface of Mars is a mosaic made up of 8 images taken on August 8. Curiosity is using these first days after landing to check its systems.

The back of the rover can be seen at the top left of the image, and two of the rover’s right side wheels can be seen on the left. Part of the pointy rim of Gale Crater forms the lighter color strip in the background. Bits of gravel, about 0.4 inches (1 centimeter) in size, are visible on the deck of the rover.
