Lake Eyre, Australia

April 20, 2011
This view of Australia's Lake Eyre was taken by the space shuttle in 1990. The lake covers about 3,600 square miles and is the lowest point in Australia at about 50 feet below sea level.It also is an ephemeral salt lake that receives less than 5 inches of annual average precipitation. Records indicate that the lake has only been completely filled with water three times in the 20th century--in 1950, 1974 and 1984. Part of the space Shuttle cargo bay is visible along the right edge of the image.
