Perched atop a modified jumbo jet, the retired Space Shuttle Discovery will fly over Washington before arriving at its permanent resting place at the Smithsonian Air and Space Museum.
Cape Canaveral, Florida
Space shuttle Discovery has one last mission to complete.
At daybreak Tuesday, the oldest of NASA's retired shuttle fleet will leave its home at Kennedy Space Center for the final time, riding on top a modified jumbo jet.
Space center workers arrived by the busloads Monday at the old shuttle landing strip, where the jet was parked with Discovery bolted on top. Security officers, firefighters, former shuttle workers and even astronauts all posed for pictures in front of Discovery.
The six astronauts who flew Discovery's final space trip a year ago were on hand to bid Discovery goodbye.
