Unveiling Angkor

The space shuttle Endeavour has used a new earth-imaging radar to photograph the area around the ancient Cambodian city of Angkor. Altho Ugh the main temple complex at Angkor has been restored, much of the'city is hidden in impenetrable Jungle'(Science, Vol 267, No 5200).

The radar, developed jointly by the Jet Propulsion Laboratory in Pasa6na, California and the German and Italian space agencies, is highly sensitive to variations in texture.
