Northern Saudi Arabia as seen from STS-62

STS062-151-220 (4-18 March 1994) --- Great numbers of circular, center-pivot irrigation plots appear in this west-looking view of the northern Saudi Arabia (center to lower left). So many plots now exist that the face of Saudi Arabia as seen from low earth orbit has changed. Until a few years ago, there were only a few scattered center-pivots. Now the entire swath of country between the shifting sands of the Ad Dahna Sand Sea (light colors center and right) and the almost soilless Nejd Plateau (left) has been darkened by thousands of these agricultural fields. The Nejd Plateau is a mass of dark rocks, some volcanic, in NW Saudi Arabia. Water from this higher country flows east towards the agricultural region where it is pumped up from underground aquifers. The weep of the Ad Dahna Sand Sea is one of the major features of Saudi Arabia (center and right) as seen from the orbiter. The dunes follow the trend of regional winds (northwesterly in the center of the view) which circulate around the Nejd plateau. The north end of the Red Sea can be seen top left with the Sinai Peninsula and Mediterranean are just visible center top. Iraq is under cloud top right.
