Built from millenniums ago, some sections of the Great Wall of China were believed visible, seen from space. Actually, you are able to trace the Great Wall by zooming in some certain pictures taken by the satellite, which seems like a confirmation that the Walls of China do deserve the "Great". Show
However, the answer for the rational doubt above about the Great Wall is a capital No, and it's more like a popular urban myth that the Great Wall can be seen with the unaided naked eye from Space. Answers from AstronautsBuzz Aldrin, the second person landed on the moon in 1969, said he didn't see the Great Wall from the moon when asked about it. Even the first astronaut of China, Yang Liwei said that he couldn't tell the great wall from the capsule window during his stay in space in 2003. Later, Chris Hadfield, a Canadian astronaut who has spent about 5 months at the International Space in 2012-2013, also confirmed that via Twitter, "The Great Wall of China is not visible from orbit with the naked eye. It's too narrow, and it follows the natural contours and colours of the landscape."  Why can't We See the Great Wall from Space?The Great Wall of China officially is a maximum 9.1 m (30 ft) wide, and for most of its length is about the same color as the soil surrounding it (made mostly of soil or stones from nearby regions), which makes it tricky to find even in a high-resolution satellite photo from Low Earth Orbit. If you are not familiar with the location of different Great Wall sections, it is even harder to find them. Seen from the Space, our mother planet is just like a white-and-blue little ball, let alone a 9.1m wide wall, and it will be invisible if over 30km height due to the incapability of human eyes. Even you may think the length of the wall affects your visibility, the thickness of the Great Wall is so small that is pretty bad for a large stretch, and to look for the Great Wall from space is like to ask a person to find a worm in a vast forest from over 1 km away. Pictures of the Great Wall of China from SpaceAlthough the Great Wall couldn't be seen by the unaided eyes, if patient, you can still pick out the Great Wall from some high-resolution space-based photographs which were taken from a satellite, and these pictures are able to show the detailed man-made features quite distinctly. In fact, NASA says astronauts can indeed see cities, highways, bridges, dams and airports, as well as city lights at night — all from in orbit. In 2004, the US astronaut Leroy Chiao took the first verifiable picture of the Great Wall on the International Space Station. This photo show several sections of the Great Wall in a region of Inner Mongolia, northern China, though he could not really see the wall with his unaided eyes at that time.

Alan Bean, of the Apollo 12 mission, recounts that all you can really make out on the Earth are lots of white clouds and snow, some blue patches, a little bit of yellow, and—every once in a while—a patch of green.
A Closer LookThe Chinese space program was shaken to learn that their own astronaut, Yang Liwei couldn’t see the wall from space. This at least confirmed the invisibility wasn’t a political conspiracy. After numerous missions to space, by astronauts from countries all over the world, nobody could see the wall. The International Space Station, which is 238,601 miles closer to the Earth than the Moon, or only 0.1% as far away, still offers no view of the Wall with the naked eye. The Great Wall of China from space. Can you see it? From: NASA Finally PhotographedIt was Chinese-American astronaut Leroy Chiao who would eventually spot the wall using a camera and 180 mm lens. Even then, he could only identify a small portion of it. The human eye is often compared to having a roughly 50 mm field of view, meaning that the 180 mm lens far surpassed human capability. Yeah, that’s obviously it, right? From: NASA Chiao took another photograph using a 400 mm lens, and experts were even less sure that he had taken a photo of the actual wall. Favorable snowfall and sunlight had seemed to be largely responsible for photographing the wall the first time. NASA also confirms the Great Wall is nearly impossible to photograph using conventional means, but says low-orbit satellites can capture it using radar.
