ISS022-E-008282 (9 Dec. 2009) --- One of the worlds leading copper mines, Escondida, in the Atacama Desert of Chile, is featured in this image photographed by an Expedition 22 crew member on the International Space Station. The copper mining industry is a major part of the Chilean economy. The mine is located 170 kilometers southeast of Chiles port city of Antofagasta, in the hyper arid northern Atacama Desert at an elevation of 3,050 meters (approximately 10,000 feet) above sea level.

The photograph features a large light tan and gray waste or spoil materials impoundment area (center) of the mine complex. The copper-bearing waste, which is a large proportion of the material excavated from open pits to the north (not in frame), is poured into the impoundment area as a liquid (gre
