Up on Mars, the rover Curiosity recently sent a self-portrait back to Earth. Perhaps for the benefit of its Facebook and twitter followers.
The self-portrait shows the clunky head of the rover, and a bit of its single robotic arm.
Dust on the lenses of the camera give the photo a distinct sepia tone. The picture was taken by one of the 17 cameras on the rover.
The camera, called the Mars Hand Lens Imager, or MAHLI is placed at the end of Curiosity's robotic arm.
Of the other images taken by MAHLI is a series of photos Curiosity's underbelly.
