Description 

Essentially a large water tank 75' in diameter and 40' deep, this facility was designed to provide a simulated zero-gravity environment in which engineers, designers, and astronauts could perform, for extended periods of time, the various phases of research needed to gain firsthand knowledge concerning design and operation problems associated with working in the space. Constructed in 1955, the Neutral Buoyancy Simulator has contributed significantly to the American manned space program, especially Projects Gemini, Apollo, Skylab, and the Space Shuttle. -- National Historic Landmark statement of significance, October 3, 1985
