text: There is the arguement that the Face is evidence of an ancient civilization. At the time the picture of the Face was taken, it was winter. Perhaps the alien markings were hidden by the cloudy haze. Mission controllers even looked again. On a cloudless, summer day, the Mars Global Surveyor drew close enough to take the another picture, in hope there was something that they didn't see. Even so, the scientists were proven right again. The Face was really a mesa, a landform common in Cydonia.
