Researchers from Kyoto University and Kajima Corporation have proposed constructing artificial-gravity buildings to enable human settlements on Mars and the Moon.
The design of the facilities features huge rotating structures that would create the effect of Earth-like gravity through centripetal force.
The proposals follow a study published earlier this month which found astronauts suffered significant bone loss, while in low-gravity environments. A year after returning to Earth, the astronauts in the study had only recovered half of the bone loss, raising concerns about the health risks humans would face when travelling to other planets.
To solve this problem, the researchers have proposed building a living facility on the Moon called Lunar Glass. The cylindrical architecture is 100 metres wide and up to 400 metres high. It completes a full rotation once every 20 seconds, generating 1G of gravity where the radius is the largest, which is equivalent...
