Face on Mars explained: on July 25, 1976, NASA's Viking 1 orbiter photographed a mesa in the Cydonia region of Mars that looked like a human face. It is about two kilometers (1.2 miles) long, and the low Sun made its shadows look like eyes, a nose and a mouth.
In 1998, Mars Global Surveyor photographed it again with about ten times the detail and different lighting: the face was gone, just an eroded mesa. A sharper image in 2001 and the HiRISE camera in 2007 (25 centimeters per pixel) confirmed it. Your brain is wired to see faces, a phenomenon called pareidolia. The mesa is real. The face is in your brain.
