Artificial Gravity

Deep Space Exploration Will Demand Artificial Gravity


Long stays in space have a major hitch. Medical studies on the effects of microgravity on astronauts after many months in low-Earth orbit (LEO) can’t get around one hard truth — humans aren’t cut out for life without gravity. Thus, artificial gravity habitats are now being discussed as a crucial component of long-duration near-Earth asteroid (NEA) mining missions.
Artificial gravity will be particularly important for years-long commercial missions where real-time telerobotics will need to be performed by crews housed in close proximity to the asteroid itself. Such gravity habitats would also be useful for years-long exploration of low-gravity bodies such as the Moon, Mars , or eventually even the moons of the outer planets.
