Self Portrait

Curiosity sends back its Facebook profile photo with this self-portrait, using a camera located on its arm to obtain the vanity pic. He's not quite Wall-E, but good enough for government work.

Robot Arms

This engineering drawing shows the location of the arm on Curiosity, which has five degrees of freedom of movement, thanks to rotary actuators known as the shoulder azimuth joint, shoulder elevation joint, elbow joint, wrist joint and turret joint.

Calibration Target

This view of the calibration target for the Mars Hand Lens Imager (MAHLI) aboard Curiosity shows the penny, a nod to geologists' tradition of placing a coin or other object of known scale as a size reference in close-up photographs of rocks.
