CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, space shuttle Discovery, at right, approaches shuttle Endeavour outside Orbiter Processing Facility-3 (OPF-3). Discovery, which temporarily was being stored in the Vehicle Assembly Building (VAB), is switching places with Endeavour, which has been undergoing decommissioning in Orbiter Processing Facility-1 (OPF-1). Both shuttles will stop briefly outside OPF-3 for a "nose-to-nose" photo opportunity. Discovery then will be rolled into OPF-1 and Endeavour into the VAB. The image was taken from the top of the VAB. In OPF-1, Discovery will undergo further preparations for public display at the Smithsonian's National Air and Space Museum Steven F. Udvar-Hazy Center in Virginia. Endeavour will be stored in the VAB until October when it will be moved into OPF-2 for further work to get it ready for public display at the California Science Center in Los Angeles.
