While many welcome the opportunity to experience the reduced gravity effects of an environment like the Moon or Mars, research has shown that this can harm things like bone strength. We also don’t know what effect gravity will have on giving birth in space or how a child growing up in a low-gravity environment will manage to come to Earth.
The Moon’s gravitational force is about 16.6 percent of the Earth’s; On Mars, it’s 38 percent closer to what you’ve experienced here on Earth.
To account for the differences, researchers and engineers from Kyoto University and Kajima Construction Co. have proposed an artificial gravity system to support humanity’s space life. The residential facility will generate gravity using centrifugal forces.
The cylindrical architecture will be 100 meters wide and 400 meters high (328 feet wide and 1,312 feet wide). It will complete a full rotation every 20 seconds and produce 1G of gravity where the radius is most incredible, equivalent to what is experienced on Earth.
The team is also considering creating core biomes and a high-speed, interplanetary transportation system that would allow passengers to move between Earth, Moon, and Mars.
Considering that the researchers don’t expect colonization efforts to become a reality until the second half of the 21st century, they still have plenty of time to work out the details and work on the funding.
