Artificial gravity is the creation of an inertial force that mimics the effects of a gravitational force, usually by rotation. Artificial gravity, or rotational gravity, is thus the appearance of a ce

…these risks. The environment of space is still largely unknown, and there will likely be as-yet-unknown hazards. Meanwhile, future technologies such as artificial gravity and more complex bioregenerative life support systems may someday be capable of mitigating some risks. Fatigue and sleep loss during spaceflight – Sleep…
Gemini 11 tethered in 1966 the GATV-5006 Agena target vehicle performing various tests including a first artificial gravity test in a microgravity environment.
Artificial gravity space station. 1969 NASA concept. A drawback is that the astronauts would be moving between higher gravity near the ends and lower gravity near the center.
Artificial gravity has been suggested for interplanetary journeys to Mars
