text: First of all, the image did have characteristics of a face. The text stated "a few days later NASA unveiled the image for all to see. The caption noted a "huge rock formation..which resembles a human head....formed by shawdos giving the illusion of eyes, nose, and mouth. The authors reasoned it would be a good way to engage the public and attract attention to Mars." The Face could simply have been the shadow of something or the lighting that caused it to look that way. "Although few scientists believed the Face was an alien artifact, photographing Cydonia became a priority for NASA when Mars Global Surveyor (MGS) arrived at the Red Planet in September 1997, eighteen long years after the Viking missions ended." The photograph from the Viking could have been a worse quality than now.
