Description
STS108-705-008 (5-17 December 2001) --- The "bulls eye" of the Richat Structure, photographed with a 70mm camera by one of the STS-108 astronauts aboard the Space Shuttle Endeavour, adds interest to the barren Gres de Chinguetti Plateau in central Mauritania, northwest Africa. The shuttle was flying at an altitude of 207 nautical miles. NASA scientists studying the STS-108 photo collection pointed out the structure represents domally uplifted, layered (sedimentary) rocks that have been eroded by water and wind into the present shape. Desert sands have invaded the feature from the south.
