Provenance

This claim has circulated since the early 20th century, appearing in textbooks and popular culture. It was definitively debunked by multiple astronauts, including Chinese astronaut Yang Liwei in 2003, who confirmed the Wall is not visible from low Earth orbit without aid. NASA has also confirmed this finding.
