The document summarizes the process of assembling the space shuttle at NASA's Kennedy Space Center in Florida. Key steps include the external tank arriving by barge and being lifted vertically in the Vehicle Assembly Building. The solid rocket boosters are attached to the external tank, followed by the shuttle engines. Meanwhile, the payload is prepared and then lifted into position on the launch pad. Finally, the fully assembled shuttle and external tank are moved to the launch pad on a crawler transporter, where it is ready for launch.
