As the sun rises over the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, tugboats tow the Pegasus Barge from the dock in the Turn Basin to a more secure mooring area. The barge is 266 ft long and 50 ft wide and has been used by the Space Shuttle Program to transport external fuel tanks over 900 miles of inland and open ocean waterways from the Michoud Assembly Facility in Louisiana to Kennedy.
