Twenty five years ago a weird picture showed up in the Jet Propulsion Lab by a NASA's Viking 2 spacecraft. It took a picture of what seemed to be a human head on planet Cydonia. People in the Jet Propulsion Lab were surprised at what they saw. Though many thought it was something formed by aliens, scientists figured it was only another Martian mesa. They said the shadows is what made it look like a face. The shadows gave the illusion of eyes, nose, and mouth, which made the Martian mesa look like an Egyptian Pharaoh. Though it was said to be only a landscape on Cydonia, the news of the face went crazy. It starred in Hollywood films, appeared in books, magazines, and so on. Others thought that NASA would rather hide the true information of the face and just say it was the shadows which made us think it was a face. Though, NASA defenders wish there was ancient civilization on Mars. On April 5, 1998, Michael Malin and his Mars Orbiter Camera team snapped a picture of the face, which came out ten times sharper than the original Viking photos. The picture revealed a natural landform; no alien monument. It's not easy to reach Cydonia and therefore makes it difficult to get a picture of the so called face. Garvin said that you could see if there were small objects on Mars, therefore no alien civilization is on Mars. This shows how the face on Cydonia is not a face, but a landscape. The shadows in the picture made the landscape appear to have a face that look human. Therefore, there are no alien artifacts on Mars.
