text: This shadowy face was discovered in 1976 when a NASA spacecraft was circling around the Red Planet. The photos that were taken of the shadows looked like an Egyptian Pharaoh. The text states, "Scientists figured it was just another Martian mesa, common enough around Cydonia, only this one had unusual shadows that made it look like an Egyptian Pharaoh." Some scientists started to believe that the Face was an alien artifact. The text states, "Although dew scientists believe the face was an alien artifact, photographing Cydonia became a priority for NASA when Mars Global Surveyor (MGS) arrived at the Red Planet in Sept. 1997, eighteen long years after the Viking missions end."
