Great Wall - NASA

The Great Wall of China and Inner Mongolia are featured in this image photographed by Expedition 10 Commander Leroy Chiao on the International Space Station. Despite myths to the contrary, the wall isn't visible from the moon, and is difficult or impossible to see from Earth orbit without the high-powered lenses used for this photo.
