Johnsville Centrifuge & Science Museum
Johnsville Centrifuge & Science Museum is located on the former Naval Air Development (NADC) site in Warminster PA. The centrifuge is the largest human centrifuge ever built and where the Mercury, Gemini and Apollo astronauts trained to understand the effects of high G-forces on the human body.
Our goal is to establish a world class educational facility that will inspire local students to pursue engineering and science careers to ensure America’s future technological leadership.
Visit us to be inspired and learn about the technological innovations made by the dedicated NADC employees and see where America’s space heroes trained.
