The Vehicle Assembly Building (VAB) is a large structure located at the Kennedy Space Center in Florida. It is primarily used for assembling and preparing spacecraft and rockets for launch. The VAB is notable for its height, making it one of the tallest buildings in the United States, and it plays a crucial role in the operations of the NASA space program. Inside the VAB, various components of rockets, such as the Space Launch System and the Space Shuttle, are brought together. The building is equipped with massive cranes and specialized equipment to facilitate the assembly process. Once assembled, the vehicles are transported to the launch pad for their missions.
