The Curiosity rover has taken its own picture – a high-resolution self-portrait using its Mastcam cameras, which look down on the rover from the rover’s “head.” The hilly rim of Gale crater is in the background. The AR or “augmented reality” tag can be seen on the rover’s deck near the centre of the image. It is similar to other AR and QR code tags which are now becoming commonplace; by taking a photo of an image of it with a smartphone, a person will be able to obtain more information about the mission even though the tag itself is millions of kilometres away. Cool high-tech geekiness!
