S95-10529 (3 May 1995) --- Inside the cavernous Vehicle Assembly Building (VAB), workers carry out the meticulous process of lifting the Orbiter Discovery from a horizontal to a vertical position. Once upright, Discovery will be transferred into a high bay for mating with the external tank and solid rocket booster assembly already mounted on the mobile launcher platform. Completing the assembly process takes about five working days. Discovery?s next destination is Launch Pad 39B, and final preparations for liftoff on mission STS-70 scheduled for June 1995.

S88-41541 (7 July 1988) --- STS-26 Discovery, Orbiter Vehicle (OV) 103, is suspended by overhead crane and large frame attached to vehicle at four points. A ground-level view shows OV-103 during operations to accomplish its mating to two solid rocket boosters (SRBs) and an external fuel tank (ET) in the vehicle assembly building (VAB) at the Kennedy Space Center (KSC). From this step OV-103 will be lifted vertically and hoisted high inside the VAB for mating with the already connected ET and SRBs. In less than two weeks, the combined components will be rolled to Pad 39B atop a mobile launch platform.

KENNEDY SPACE CENTER, FLA. - The Space Shuttle orbiter Atlantis approaches the Vehicle Assembly Building (VAB). It is being towed from the Orbiter Processing Facility (OPF) to allow work to be performed in the bay that can only be accomplished while it is empty. Work scheduled in the processing facility includes annual validation of the bay's cranes, work platforms, lifting mechanisms, and jack stands. Atlantis will remain in the VAB for about 10 days, then return to the OPF as work resumes to prepare it for launch in September 2004 on the first return-to-flight mission, STS-114.

The shuttle assembly rests on the mobile launcher platform, which will be lifted by the crawler-transporter for the slow journey to the pad. Rollout was originally planned for just after midnight on July 10 but the move was canceled by NASA managers because unfavorable weather was predicted to arrive in the launch area before the vehicle would be secured at the pad.

The walls of the Butler Building at Kennedy Space Center come tumbling down, with the help of the crane in the background. The building, which is near the Orbiter Processing Facility, is being demolished in order to extend the crawlerway leading to the high bay of the Vehicle Assembly Building (VAB), part of KSC's Safe Haven project. The goal of Safe Haven is to strengthen readiness for Florida's hurricane season by expanding the VAB's storage capacity. Construction includes outfitting the VAB with a third stacking area, in high bay 2, that will allow NASA to preassemble stacks and still have room in the VAB to pull a Shuttle back from the pad into the safety of the VAB if severe weather threatens. The VAB can withstand winds up to 125 mph

S79-35236 (23 July 1979) --- The space shuttle orbiter 101 Enterprise is seen in this high angle view as it is being moved from Pad A, Launch Complex 39 at the Kennedy Space Center (KSC) to the Vehicle Assembly Building (VAB). Though only 3.5 miles separate the launch pad and the VAB, the journey of the orbiter, its solid rocket boosters and external tank takes more than 11 hours. The move back to the VAB represents the end of several weeks of fit and function checks performed on the vehicle, prepatory to eventual launch readiness of the first actual flight vehicle in the orbiter flight test (OFT) series -- the Columbia. The SRB/ET/Enterprise cluster will soon be taken apart inside the VAB and the orbiter will be taxied back to the Palmdale, California manufacturing facility of Rockwell International.

S88-42092 (15 July 1988) --- STS-26 Discovery, Orbiter Vehicle (OV) 103, rollover at Kennedy Space Center (KSC) is closely monitored by engineers and technicians in the late stages of the move from the orbiter processing facility (OPF) to the vehicle assembly building (VAB) as preflight preparations continue. A large crowd of KSC employees and other spectators watches in the background as OV-103, supported by its landing gear, is pulled toward VAB (background). While in the VAB, OV-103 will be mated to two solid rocket boosters (SRBs) and an external fuel tank.

KENNEDY SPACE CENTER, FLA. -- In Vehicle Assembly Building (VAB) high bay 4, installation of a Payload Bay Door Drying Enclosure is in progress. The enclosure will keep moisture from being absorbed into the graphite epoxy used on the payload bay doors of the Shuttle orbiters with the assistance of mini-Portable Purge Units (PPUs). Once in operation, the enclosure will allow NASA the option to store an orbiter in the VAB bay up to 180 days in a "standby-to-stack" mode.

KENNEDY SPACE CENTER, FLA. -- A crawler-transporter with mobile launcher platform on top makes its way from the Orbiter Processing Facility along the once-buried portion of the Apollo-era crawlerway leading to the Vehicle Assembly Building (VAB) high bay. The road was restored as part of KSC’s Safe Haven project. High bay 2 provides a third stacking area.. The primary goal of the Safe Haven construction project was to strengthen readiness for hurricane season by expanding the VAB’s storage capacity. The new area, in high bay 2, will allow NASA to preassemble stacks and still have room in the VAB to pull a Shuttle back from the pad if severe weather threatens. Potential rollouts of the Space Shuttle to the launch pad from high bay 2 will involve making a turn around the north side of the VAB in contrast to the straight rollouts from high bays 1 and 3, on the east side of the VAB facing the launch pads

KENNEDY SPACE CENTER, FLA. -- Looking eastward, the Vehicle Assembly Building (VAB) in the Launch Complex 39 area can be seen with its new coat of paint, along with newly painted American flag and NASA logo. The improved look was finished in time to honor NASA's 40th anniversary on Oct. 1. In order to do the job, workers were suspended on platforms from the top of the 525-foot-high VAB. One of the world's largest buildings by volume, the VAB is the last stop for the Shuttle before rollout to the launch pad. Integration and stacking of the complete Space Shuttle vehicle (orbiter, two solid rocket boosters and the external tank) takes place in High Bays 1 or 3. Stretching from the side of the VAB, on the right, is the crawlerway, used to transport the Space Shuttle to the launch pad. Beyond the VAB is Banana Creek

The orbiter Atlantis, being towed from the Shuttle Landing Facility toward the Vehicle Assembly Building (VAB) , intersects the morning sun's rays. In the background, to the right of the VAB, are the Orbiter Processing Facility 1 and 2. Atlantis spent 10 months in Palmdale, CA, undergoing extensive inspections and modifications in the orbiter processing facility there. The modifications included several upgrades enabling it to support International Space Station missions, such as adding an external airlock for ISS docking missions and installing thinner, lighter thermal protection blankets for weight reduction which will allow it to haul heavier cargo. Atlantis will undergo preparations at KSC in Orbiter Processing Facility 2 for its planned flight in June 1999

KENNEDY SPACE CENTER, FLA. - The orbiter Discovery rests in the transfer aisle of the Vehicle Assembly Building (VAB) after rollover from the Orbiter Processing Facility (OPF) bay 3. This marks a major milestone in the march to Return to Flight. First motion in the OPF was at 1:29 a.m. EST. Inside the VAB, Discovery will be mated to the External Tank_Solid Rocket Booster assembly for Return to Flight mission STS-114. After all umbilicals have been connected, workers will perform an electrical and mechanical verification of the mated interfaces to verify all critical vehicle connections. A Space Shuttle interface test is performed to verify vehicle interfaces and vehicle-to-ground interfaces. The launch processing system is used to control and monitor orbiter systems as required. Space Shuttle Discovery will roll out to Launch Pad 39B approximately one week after the rollover to the VAB. The launch window for mission STS-114 is May 15 to June 3.

KENNEDY SPACE CENTER, FLA. - The orbiter Atlantis, on top of the orbiter transporter, begins its turn after rolling out of the Orbiter Processing Facility, heading for the Vehicle Assembly Building (VAB). In the VAB it will be mated with the twin Solid Rocket Boosters and External Tank already stacked on the Mobile Launcher Platform. Atlantis is being readied for mission STS-121, the second Return to Flight mission to the International Space Station. This is Atlantis’ 27th space flight and the mission is the 18th flight to the Space Station. It is a Utilization and Logistics Flight. Launch is scheduled during a planning window between Sept. 9 and Sept. 24.
