Neutral Buoyancy Simulator
Backstory and Context
According to National Park Service, having capability to support research and testing of operational technique and materials needed to successfully perform space-manned missions, the Neutral Buoyancy Simulator contributed significantly to the American manned space program(1).
"Projects Gemini, Apollo, Skylab and the Space Shuttle have all benefited from the Neutral Buoyancy Simulator"(1). "Until the mid-1970s, when an additional facility was constructed at the Johnson Space Flight Center to support the Space Shuttle Program, this facility was the only test facility that allowed astronauts to become familiar with the dynamics of body motion under weightless conditions" (1).
In 1985, The Neutral Buoyancy Simulator was declared a National Historic Landmark (1).
