STS040-614-066 (5-14 June 1991) --- St. Louis, Missouri-East St. Louis, Illinois and surrounding area were photographed by the STS 40 crewmembers aboard the Space Shuttle Columbia. The winding Mississippi River serves as a reference point for finding features of the area. Busch Stadium is clearly seen. NASA photo experts studying the STS 40 imagery claim photographs of this type aid in following demographic changes and in planning for development. The ground track of STS-40 and the existence of exceptionally clear skies during much of the nine-day flight permitted photographic acquisition of several cities not generally seen from the space flights flying at 28-degree inclinations to the Equator.
