Workers secure the high-fidelity space shuttle model to the structure that will cradle the model on its journey from NASA’s Kennedy Space Center in Florida to Johnson Space Center's visitor center in Houston atop a barge.

The model was built in Apopka, Fla., by Guard-Lee and installed at Kennedy Space Center Visitor Complex in 1993.The model has been parked at the turn basin the past five months to allow the Kennedy Space Center Visitor Complex to begin building a new facility next year to display space shuttle Atlantis in 2013.
