Are there any man-made objects that astronauts can see from orbit?


There was once a claim that, with the naked eye, astronauts could see the Great Wall of China, but to my knowledge this has been retracted leaving no other contender that I know about off hand. At night, however, you can see cities and roadways as lines and splotches of light.
