NASA’s Vehicle Assembly Building (VAB)

Vehicle Assembly Building at NASA

NASA’s Vehicle Assembly Building (VAB) at Kennedy Space Center is one of the largest buildings in the world by volume. Four Empire State Buildings could fit inside the VAB, with enough room leftover for Yankee Stadium on top. The interior volume is so great that rain clouds sometimes form at the ceiling!  The VAB was used to prepare moon rockets for launch, and space shuttles for orbit. On the outside of the building are the U.S. flag and NASA logo. For scale, the flag’s stars are 6 feet wide, and the stripes are the width of a bus.
