Large white centrifuge with blue base and logos

711 HPW centrifuge simulates spaceflight for astronauts. The only human-rated centrifuge within the Department of Defense is shown at Wright-Patterson Air Force Base, Ohio, June 20, 2025. Five astronauts from NASA, the European Space Agency and the Canadian Space Agency completed centrifuge training, which simulates gravitational forces, or g-forces, experienced during launch and return to Earth. The Air Force Research Laboratory’s 711th Human Performance Wing owns and operates the centrifuge. (U.S. Air Force photo / Richard Eldridge)
