The space shuttle is the world's first reusable spacecraft. Before the shuttle was developed, al spacecraft could only be used once before being destroyed after tokeoff. The shuttle is launched into space with the help of two giant boosfer rockets. These boosters detach and fall back into the sea to be used again. The only part of the shuttle that cannot be reused is the giant fuel tank that separates from the shuttle after eight minutes and burns up in the atmosphere.
