null-g n.

(as adjective) relating to, producing, or designed for a condition of zero gravity; (as noun) zero gravity: the state or condition in which there is no apparent force of gravity acting on a body, either because the force is locally weak, or because both the body and its surroundings are freely and equally accelerating under gravity; (also) a device or system that negates the force of gravity; cf. slightly earlier null-grav n.

Also null-gee.

    ‘Speaking of rotation—how are you handling null-g deconditioning in your people? I don’t—’ his eyes inventoried the enormous structure, ‘I don’t even see an exercise wheel. No spinning gym?’ ‘There’s a null-g gym. The rotating personnel get a month downside after every three-month shift.’
