July 22, 1995 The Face on Mars Picture Credit: NASA,Viking Project, Explanation: This image, showing what looks to be a human face sculpted on the martian surface, was produced using data from NASA's Viking 1 orbiter in 1976. Described in a press release as a "face-like hill" it caused some to offer the sensational speculation that it was an artificial construct built by an intelligent civilization on Mars! As a result, this image was splashed across the covers of many grocery store tabloids at the time. A detailed analysis of multiple images of this feature reveals a natural looking martian hill whose illusory face-like appearance depends on viewing angle and angle of illumination. For more information about the picture see the NSSDC Photo Gallery of Mars. For a detailed discussion of the "Face on Mars" see Calvin J. Hamilton's Face on Mars page.
