Discovery and Endeavour
Shuttles Endeavour and Discovery switched locations at Kennedy Space Center. Endeavour was moved out of Orbiter Processing Facility-1 (or OPF-1). Discovery was moved out of the Vehicle Assembly Building (VAB) and both shuttles were posed briefly near OPF-3 for a "nose-to-nose" photo opportunity.
Discovery then will be rolled into OPF-1 and Endeavour into the VAB.
