The most flown spacecraft in history, Discovery is heading from its old home base at NASA's Kennedy Space Center to its new home base at the Smithsonian National Air and Space Museum's Udvar-Hazy Center in Virginia.
First stop was Dulles International Airport, where the shuttle and its carrier plane touched down this morning. Over the next day or so, Discovery will be lifted off the jet and brought over to the adjacent Udvar-Hazy Center for display on Thursday alongside the prototype shuttle Enterprise, which has been at the museum since 1985. Next week, Enterprise will be flown from Dulles to New York, where it will go on exhibit at the Intrepid Sea, Air and Space Museum.
