Can astronauts actually see the great wall from space?

Generally, no. And certainly not from the moon

Elaborate:

The Great Wall is generally only visible under very ideal atmospheric conditions and at a very low altitude. The issue with it is that it too closely follows the terrain and its color is too close to that of its surroundings to pop out at our orbiting brethren. Ironically, much lesser things can be seen, such as roads across deserts, because of their contrast with their environment. The myth that astronauts can see the Great Wall from space was supposedly perpetuated by a “A 1932 Ripley’s Believe It or Not! cartoon [claiming] that the wall is ‘the mightiest work of man, the only one that would be visible to the human eye from the moon.'”
