Earth Observations taken by the Expedition 10 crew

ISS010-E-23451 (7 April 2005) --- Khartoum, Sudan is featured in this image photographed by an Expedition 10 crewmember on the International Space Station (ISS). Sudan’s capital city Khartoum, which means Elephant’s Trunk, describes the shape of the Nile River where the Blue and the White Nile Rivers meet to form the united Nile that flows northward into Egypt. This image shows the rivers near the end of the dry season. The White Nile (western branch) runs through Sudan from Uganda. The White Nile’s equatorial source produces a flow that runs at a nearly constant rate throughout the year. The nearly dry Blue Nile from the highlands of Ethiopia swells in the late summer and early fall with rains from the summer monsoons. The flow can be so great the Nile flows backward at the junction. In recent years, floods in Khartoum have occurred in August with heavy monsoon rainfall. Khartoum is one of the largest Muslim cities in North Africa, but has a fairly short history.
