One great world fact is that that the Great Wall of China is NOT the only man made construction to be seen from space. This is another one of those world geography facts that is often misunderstood. From space, by using just their eyes, astronauts have seen plenty of man-made objects.

The Great Wall of China can be seen from space, but it is very difficult to pick out because it is a brown line nestled on a brown terrain.
