Today we have a picture of the rover Curiosity on Mars.
This picture was taken by a camera on the end of Curiosity's robotic arm, the camera is designed to take close-up images of details on rocks, but it can also rotate to image the rover itself. It took many pictures, which were stitched back together after they were transmitted back to earth. Only the shadow of the robotic arm is visible because it can rotate out of the image area.
