The Space Shuttle was a manned orbital rocket and spacecraft system operated by NASA on 135 missions from 1981 to 2011. The system combined rocket launch, orbital spacecraft, and re-entry spaceplane with modular add-ons. Major missions included launching numerous satellites and interplanetary probes,[2] conducting space science experiments, and 37 missions constructing and servicing the International Space Station. A major international contribution was the Spacelab payload suite, from the ESA.
Major components included the orbiters, recoverable boosters, external tanks, payloads, and supporting infrastructure — orchestrated by thousands of people on the ground and crewed by an elite cadre of astronauts.
