text: After the discovery of the Face, NASA unveiled the image for the public to see. A caption noted a "huge rock formation... which resembles a human head... formed by shadows giving the illusion of eyes, nose, and a mouth." Authors who knew about it reasoned that it would be a good way to engage the public's attraction to Mars, which it successfully did. The pharaoh look-alike of the mesa was named "The Face on Mars" has since become a pop icon. It has starred in Hollywood film, appeared in books, magazines, radio talk shows, even haunted grocery store checkout lines for 25 years. Many conspiray theorists said that NASA was just hiding more from the public since they said it was only a natural landform. Aliens and ancient civilization became a wide belief, even scientists believed in this. But due to this, the Face became a priority for NASA when Mars Global Surveyor (MGS) arrived at the Red Planet in September 1997; 18 years after the Viking missions ended. The chief scientist for NASA's MArs Exploration Program, Jim Garvin said "We felt this was important to taxpayers."
