The Centrifuge Accommodations Module (CAM) is a cancelled element of the International Space Station. Although the module was planned to contain more than a centrifuge, the 2.5 m (8.2 ft) centrifuge still was considered the most important capability of the module. The centrifuge would have provided controlled acceleration rates (artificial gravity) for experiments and the capability to:
Expose a variety of biological specimens that are less than 24.5 in (0.62 m) tall to artificial gravity levels between 0.01g and 2g.
Simultaneously provide two different artificial gravity levels.
Provide partial...
