STS058-081-008 Washington, D. C., Potomac River, Virginia, U.S.A. October 1993 The Potomac River can be seen entering the scene from the northwest midway between the left center and upper left, going through Washington, D.C., and exiting the scene to the south near the center bottom, of this mostly north-looking low-oblique view. The Potomac passes over the Great Falls (not discernible) just to the northwest of Washington, D.C., and enters a tidal estuary just to the south of the city. The city of Washington, D.C., visible to the right of the center of the image, is the capital of the United States. The runways of Dulles International Airport can be seen near the left center of the image. The north-south runways of Andrews Air Force Base are visible near the right center of the image.
