Vehicle Assembly Building (VAB)

The Vehicle Assembly Building (VAB) is a large structure at NASA’s Kennedy Space Center used for assembling and integrating spacecraft and launch vehicles. It provides a controlled environment where engineers and technicians connect rocket components, such as the core stage, boosters, and payloads, into a complete launch vehicle. Its spacious design allows for horizontal or vertical assembly, depending on the vehicle. The VAB also protects sensitive equipment from weather and environmental factors, ensuring the safe construction of spacecraft before they are transported to the launch pad for takeoff.
