Mission: SPACE

A genuine NASA-grade centrifuge dressed as a four-passenger space capsule. Riders pick Orange (Mars) or Green (Earth orbit). Orange spins the centrifuge fast enough to simulate launch g-forces — there's a famously assertive 'press your head back' instruction — while Green delivers the same visuals at a flat speed, making it a moving picture without the body force. The visuals (a journey to Mars, a stop at the ISS) are good; the ride sensation on Orange is unique among Disney attractions.
