STS102-303-017 (8-21 March 2001)--- The STS-102 crew members used a 35mm camera on the flight deck of the Space Shuttle Discovery to record this image of the Aswan High Dam. The structure was completed in 1970 and is one of the largest earthen embankment dams in the world. It is 364 feet (111 meters) tall, 12,565 feet (3,830 meters) long and nearly 3,281 feet (1,000 meters) wide. When it was built the new reservoir required relocation of nearly 100,000 residents and some archaeological sites. Although the reservoir has benefited Egypt by providing power and controlling floods, according to NASA scientists, it has also had detrimental effects on the Nile system. Before the dam, an estimated 110 million tons of silt was deposited by the annual flood of the Nile, enriching agricultural lands and maintaining the land of the Nile delta. Now this sediment is trapped behind the dam, requiring artificial fertilization of agricultural lands and leading to erosion and saltwater intrusion where the Nile river meets the Mediterranean Sea.
