 There are three main parts of a Space Transportation System known as the "shuttle": 1) an orbiter with three main engines; 2) an external tank; and 3) a solid rocket booster (SRB). The purpose of the shuttle is to deliver payloads into orbit, conduct experiments, and to dock with satellites and space stations. The shuttle is launched in an upright position. Thrust to power the shuttle comes from the main engines and two SRBs. The orbiter and solid rocket booster are reusable. |
