Purported Great Wall Image Turns Out to be River
Purported Great Wall Image Turns Out to be River
By Peter B. de Selding Space News Staff Writer, SPACE.com PARIS -- An embarrassed European Space Agency (ESA) on May 19 retracted an earlier assertion that its small Proba Earth observation satellite took a remarkably clear image of China's Great Wall as it orbited 600 kilometers overhead. "The Great Wall's relative visibility or otherwise from orbit has inspired much recent debate," the agency said in a May 11 press release accompanying a satellite image purporting to show "a winding segment of the 7,240-kilometer-long Great Wall of China situated just northeast of Beijing." The image turns out to have been of a river feeding into the Miyun Reservoir. "Further acquisitions of the region are being planned with other ESA instruments to investigate the subject further," ESA said in a May 19 statement. The agency thanked professors from California State University and the Fudan University of Shanghai for helping correct the error. http://story.news.yahoo.com/news?tmp...nsouttoberiver |
