In 1976, a mesa was discovered on Mars that resembled a face, calling it the "Face on Mars," or just the "Face." The face was located in a region on Mars called Cydonia. The Face is just a mesa on Mars. A few scientists believed the Face was an alien artifact, and some conspiracy theorists believe the Face was evidence of life on Mars that NASA would rather hide. The article says, "And so on April 5, 1998, when Mars Global Sruveyor flew over Cydonia for the first time, Michael Malin and his Mars Orbiter Camera (MOC) team snapped a picture ten times sharper than the original Viking Photos. Thousands of anxious web surfers were waiting when the image first appeared on a JPL web site, revealing ... a natural landform. There was no alien monument after all." This quate proves with the image that the Face on Mars isn't a face, it's a natural landform. The text also says, "Nevertheless, on April 8, 2001-a cloudless summer day in Cydonia-Mars Global Surveyor drew close enough for a second look." "'As a rule of thumb, you can discern things in a image 3 times bigger than the pixel size,' he added. 'So if there were any objects in the picture like airplanes on the ground or Egyptian style pyramids or even small shacks, you could see what they were!'" These quotes are telling how good the picture is so if there were any alien structures, we would be able to see them. The article also states, "What the picture actually shows is the Martian equivalent of a butte or mesa-landforms common around the American West." What this quote is saying is the face was confirmed to be a Martian mesa, not an alien artifact or proof of life on Mars.
