Shuttle Detects Buried Great Wall

Radar aboard the shuttle Endeavour has revealed segments of the Great Wall of China lost in centuries of desert sand, a NASA scientist said.

The images from an April 1994 mission in some cases show two parallel sections of wall built centuries apart, said Diane Evans, the spaceborne imaging project scientist at NASA’s Jet Propulsion Laboratory in Pasadena.

The Great Wall findings and the wider archaeological potential of space-based radar were presented at a University of Florida symposium Thursday in Gainesville.
