Real or not, the astronauts can see the Great Wall of China from outer Space

It is extremely disappointing. When China's first astronaut Yang is Li Wei said in 2003 that he could not see the Great Wall of China from space length 6,350 km legend this happen since the 18th century and is written in textbooks as well. However, if Chinese walls painted in blue or pink, it could be seen. But the light faded and some were covered. As well as the dark brick. It camouflaged and can not be seen from space.

In theory, if it is higher in low-earth orbit approximately 160 kilometers above the Earth's surface, or we might see this wall. But with the proviso that it must be covered with snow. The snow will reflect the wall. The fact is that in this altitude. The road in the desert and cities It is easily visible over again. Not only that Some legends say that the stage is visible from the moon really. But the resolution of the eye indicates that it is impossible. If you want to find true legendary astronauts who have eyes to 17,000 times better than humans, so to see the Great Wall from the moon.
