The MBS consisted of the forward part of the flight deck of the Space Shuttle.
While the MBS provided crews with computer generated visual scenes out of the forward windows only, the FBS and the GNS were capable of supplying forward, aft, and overhead window views.
A central simulation control office monitored the health of the facility, scheduled its use, and responded to maintenance requests.
Depending on training requirements, simulations were conducted with varying levels of interconnection with other simulators or control centers, each of which had a unique identifier used internally within the training and flight control divisions.
As the Space Shuttle Program ended in July 2011, all the simulators in JSC's SMS complex were mothballed and prepared for removal and transport as excess NASA inventory throughout 2012.
