STS-27 Atlantis, Orbiter Vehicle (OV) 104, is suspended via overhead crane, attached at four points, in the Kennedy Space Center (KSC) Vehicle Assembly Building (VAB). Below OV-104 on the mobile launcher platform are the external tank (ET) and solid rocket boosters (SRBs). During ET/SRB mating operations, OV-104 will be mounted atop the ET.

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.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, the Space Shuttle Program's final solid rocket booster assembly is stationed in the transfer aisle of the Vehicle Assembly Building. The right and left forward assemblies, which were refurbished and processed at Kennedy, are comprised of three components -- nose cap, frustum and forward skirt. Inside the Vehicle Assembly Building, the boosters will be stacked and then joined to an external fuel tank and space shuttle Atlantis for the STS-135 mission to the International Space Station. STS-135 is targeted to launch June 28, and will be the last spaceflight for the Space Shuttle Program. Photo credit: NASA/Frank Michaux

CAPE CANAVERAL, Fla. -- Repair work to space shuttle Discovery's external fuel tank continues in the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida. Technicians are modifying 94 support beams, called stringers, on the tank's intertank region by fitting pieces of metal, called radius blocks, over the stringers' edges. After modifications to the stringers are complete, foam insulation will be re-applied to the tank. Discovery's next launch opportunity to the International Space Station on the STS-133 mission is targeted for Feb. 24.

STS-26 Discovery, Orbiter Vehicle (OV) 103, mated with the external tank (ET) and solid rocket boosters (SRBs), is framed by Kennedy Space Center's (KSC's) vehicle assembly building (VAB) doorway as it rolled out. This high angle view shows OV-103 atop the mobile launch pad and crawler transporter as it begins its slow exit from VAB en route to launch complex (LC) pad 39B. The move began shortly after midnight on the nation's 212th birthday. Ceremonies marking the event were held later during daylight hours.

S84-25872 (6 Jan 1984) --- Progress continues at the Kennedy Space Center (KSC) as the Space Shuttle Challenger is moved into the Vehicle Assembly Building (VAB) for mating to its two Solid Rocket Boosters (SRB) and External Fuel Tank (ET). The flight of STS-41B will carry five astronaut crew members into space for the performance of a variety of duties. Launch is scheduled for February 3, 1984.

S84-35097 (May 1984) --- The Space Shuttle Orbiter 103 is about to be hoisted into a tail-toward-ground mode for mating to its two solid rocket boosters (SRB) and an external tank (ET) (awaiting the maneuver high out of frame) in the Kennedy Space Center's (KSC) huge vehicle assembly building (VAB). After its arrival here from the manufacturer in Palmdale, California, Discovery underwent extensive pre-launch preparations in the nearby processing facility (OPF).

S83-39238 (1 Aug. 1983) --- The giant cluster of spaceflight hardware for NASA's eighth Space Transportation System (STS) mission begins its slow move to the launch pad at launch complex 39 at NASA's Kennedy Space Center (KSC). Following its mating to the two solid rocket boosters (SRB) and the external fuel tank (ET) in the huge vehicle assembly building (VAB), the space shuttle Challenger is slowly moved to the launch pad atop the mobile launch platform.

S90-42289 ( 3 July 1990) --- Kennedy Space Center (KSC) workers watch as Columbia, Orbiter Vehicle (OV) 102, along with its external tank (ET) and two solid rocket boosters (SRBs) atop the giant crawler transporter, rolls back to KSC's Vehicle Assembly Building (VAB). The rollback was caused by a hydrogen leak that stopped the STS-35 countdown during ET fueling, 05-29-90. Once in the VAB, OV-102 and its stack will be demated, and OV-102, with its Astronomy Laboratory 1 (ASTRO-1) payload aboard, will be moved to the Orbiter Processing Facility (OPF) to await return to KSC Launch Complex (LC) Pad 39A. View provided by KSC with alternate number KSC-90PC-901.

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.

KENNEDY SPACE CENTER, FLA. - Space Shuttle Discovery, atop the Mobile Launcher Platform, slowly rolls out of the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center. First motion was at 2:04 p.m. EDT. The Shuttle comprises the orbiter, External Tank (ET) and twin Solid Rocket Boosters (SRBs). The Mobile Launcher Platform moved by the Crawler-Transporter underneath. The Crawler is 20 feet high, 131 feet long and 114 feet wide. It moves on eight tracks, each containing 57 shoes, or cleats, weighing one ton each. Loaded with the Space Shuttle, the Crawler can move at a maximum speed of approximately 1 mile an hour. A leveling system in the Crawler keeps the Shuttle vertical while negotiating the 5 percent grade leading to the top of the launch pad. Launch of Discovery on its Return to Flight mission, STS-114, is targeted for May 15 with a launch window that extends to June 3. During its 12-day mission, Discovery’s seven-person crew will test new hardware and techniques to improve Shuttle safety, as well as deliver supplies to the International Space Station. Discovery was moved on March 29 from the Orbiter Processing Facility to the VAB and attached to its propulsion elements, a redesigned ET and twin SRBs.

STS-28 is a Department of Defense dedicated mission. Crew members for the mission are: Commander Brewster H. Shaw, Pilot Richard N. Richards, and Mission Specialists Mark N. Brown, James C. Adamson, and David C. Leestma.

STS-32 Columbia, Orbiter Vehicle (OV) 102, rolls through the morning's foggy mist atop the mobile launcher platform and crawler transporter to Kennedy Space Center (KSC) Launch Complex (LC) Pad 39A. OV-102's wings appear on either side of the two solid rocket boosters (SRBs) and external tank (ET). Rollout from the Vehicle Assembly Building (VAB) began at 2:32 am Eastern Standard Time (EST), and OV-102 was on the pad pedestals about 8 hours later. This marks the first time a Space Shuttle has been at LC Pad 39A since 01-12-85 when OV-102 was launched on mission 61C. View provided by KSC with alternate number KSC-89PC-1259.

First motion of the Shuttle out of the Vehicle Assembly Building (VAB) was at 2:04 p.m. EDT. The Mobile Launcher Platform is moved by the Crawler-Transporter underneath. The Crawler is 20 feet high, 131 feet long and 114 feet wide. It moves on eight tracks, each containing 57 shoes, or cleats, weighing one ton each. Loaded with the Space Shuttle, the Crawler can move at a maximum speed of approximately 1 mile an hour. A leveling system in the Crawler keeps the Shuttle vertical while negotiating the 5 percent grade leading to the top of the launch pad. Launch of Discovery on its Return to Flight mission, STS-114, is targeted for May 15 with a launch window that extends to June 3. During its 12-day mission, Discovery’s seven-person crew will test new hardware and techniques to improve Shuttle safety, as well as deliver supplies to the International Space Station. Discovery was moved on March 29 from the Orbiter Processing Facility to the VAB and attached to its propulsion elements, a redesigned ET and twin SRBs.
