River Nile, Egypt, seen from the International Space Station (ISS). North is towards bottom left. Agricultural fields (green) are sustained by the waters of the Nile (dark blue) as it flows right to left through the desert (brown). The Nile has eroded into the desert, leaving a plateau (up to 500 metres high) and the many water-eroded valleys seen here. Irrigation has enabled the farmed area to expand (top right) from the narrow floodplain onto the plateau slopes. This 60-kilometre-long stretch of the river flows past the city of Luxor (grey, upper centre) and its Ancient Egyptian ruins. The ISS orbits around 380 kilometres above the Earth. Photographed on 14 February 2003.
