text: Spacecrafts flying around Mars could have cause the face to appear. The air that is blowing out of the spacecraft could of blown the dirt into piles. Piles of dirts can form since the scapecraft is big. When the scapecraft takes off it could form the face because when air is blown out it leaves a mark. A spacecraft couldn't have left a mark by the face. The fuel on the spacecraft could of left a mark after blasting off Mars.
