The process of sending a crew to the outer space starts in the Vehicle Assembly Building (VAB). There, the orbiter, external tank (ET) and solid rocket busters (SRB) are attached. The VAB is located at NASA’s Kennedy Space Center (KSC) and it is the largest one story building in the world. It covers 3.25 hectares (8 acres) and it is 160 meters (525 ft) tall, 218 meters (716 ft) long and 158 meters (518 ft) wide.
