the space shuttle is a transpot vehicle that transports space station parts and satlits into space wich orbot the earth. there has been four launches to make the international space station and they have all landed safely back on earth. Since 1981 there has been over 134 space shuttle lurnches into space or the atmosshere some have crashed but most of them have made it home

On the space shuttle there two main rockets. the big orange one has all the fuel that helps the white ones to add thrust to leave the atmosphere. and the two white ones on the side give all the boost they add thrust. two minutes later the rockets fall off and they plunge back to the earth with parachutes and the rest of the time the rockets on the back of the shuttle push it toward the destination. it takes two days to get to the international space station and they stay thier for a month or two

On April 12, 1981,the space shuttle Columbia became the first shuttle to orbit the Earth. it was lunched at the kenndey space station**.**The Space Shuttle did 27 succesful missons until February 1, 2003, when the space shuttle disintegrated over Texas during re entry into the atmoshere, with the loss of all seven crew members.

The shuttle stack launches vertically like a conventional rocket from a mobile launch platform. It lifts off under the power of its two solid rocket boosters and its three main engines, it is fueled by liquid hydrogen and liquid oxygen from the external tank. The space shuttle has a two main engins the boosters are used only for the first stage, while the main engines burn for both stages. About two minutes after liftoff, staging occurs: the rockets are released, and shortly begin falling into the ocean to be retrieved for reuse. The shuttle orbiter and external tank continue to ascend under power from the three main engines and their inertia. Upon reaching orbit, the main engines are shut down, and the external tank is jettisoned downward and falls to burn up in the atmosphere. However, it is possible for it be re-used in orbit for various applications.[3] At this point, the orbital maneuvering system (OMS) engines may be used to adjust or circularize the achieved orbit.

The Space Shuttle has a large cargo bay. It is capable of carrying a large payload, such as a satellite, into space. The doors open to allow a satellite to be launched into orbit. The cargo bay can also be used to carry laboratory equipment to perform experiments in space. The shuttle also has a remote manipulator arm, built by Canada. This arm is used to lift a payload, such as a satellite out of the cargo bay. The remote manipulator arm can also be used to retreive a broken satellite from space. It can put the satellite back into the cargo bay allowing it to be returned to Earth for repair.

To do this, the shuttle is carried piggyback on a converted Boeing 747 jet.
