Shuttle Mission Simulator
From Wikipedia, the free encyclopedia
The Shuttle Mission Simulator (SMS) consists of two simulators in Building 5 of Johnson Space Center. One simulator, the fixed-base, includes a high-fidelity mockup of the flight deck of a Space Shuttle, as well as a low-fidelity mockup of the middeck. The motion-base simulator consists of front flight deck of the Space Shuttle. It can be tilted and shaken for increased realism, as well as tilted 90 degrees on its back for launch simulations. Before a flight, astronauts will log many hours in these two simulators. In both simulators, computer screens simulate the views out the windows, and every switch and key is modeled realistically. Simulator technicians can input numerous failures and problems to verify that astronauts can cope before a flight.
