The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC) in Florida, designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V, the Space Shuttle and the Space Launch System, and stack them vertically onto one of three mobile launcher platforms used by NASA.
Months before a launch, the three stages of the Saturn V launch vehicle and the components of the Apollo spacecraft were brought inside the Vehicle Assembly Building (VAB) and assembled, in one of four bays, into a 363-foot (111 m)-tall space vehicle on one of three Mobile Launchers (ML).
LC-39 pads A and B were completed by October 1965 (planned Pads C, D and E were canceled), the VAB was completed in June 1965, and the infrastructure by late 1966. The complex includes: the Vehicle Assembly Building (VAB), a 130,000,000 cubic feet (3,700,000 m 3) hangar capable of holding four Saturn Vs. The VAB was the largest structure in the ...
NASA currently uses crawler-transporter 2 to transport the Space Launch System with the Orion spacecraft atop it from the Vehicle Assembly Building to Launch Pad 39B for the Artemis missions. Early in 2016, NASA finished upgrading crawler-transporter 2 (CT-2) to a "Super Crawler" for use in the Artemis program. [10]
The reigning title holder for world’s most powerful rocket saw action on both its center core and its two solid rocket boosters this month, with pieces for the Artemis II launch coming together ...
Launch Complex 39A (LC-39A) is the first of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida.The pad, along with Launch Complex 39B, was first constructed in the 1960s to accommodate the Saturn V launch vehicle, and has been used to support NASA crewed space flight missions, including the historic Apollo 11 moon landing and the Space Shuttle.
It runs between the Vehicle Assembly Building and the two launch pads at Launch Complex 39. It has a length of 3.4 and 4.2 miles (5.5 and 6.8 km) to Pad 39A and Pad 39B , respectively. A seven-foot (2 m) bed of stones lies beneath a layer of asphalt and a surface made of Alabama river rocks.
With the advent of the Space Shuttle program in the early 1980s, the original structure of the launch pads were remodeled for the needs of the Space Shuttle.Pad 39A hosted all Space Shuttle launches until January 1986, when Space Shuttle Challenger would become the first to launch from pad 39B during the ill-fated STS-51-L mission, which ended with the destruction of Challenger and the death ...
