Japan projects artificial gravity facilities to house humans on the Moon and Mars


The designers warn that the complete construction of the facility will take about 100 years, although they hope to build a simplified version on the Moon by 2050 .

Kyoto University and Kajima corporation in Japan will design, in a joint, facilities with artificial gravity that allow life on the Moon and Mars. The huge rotating structures, which would recreate an Earth-like gravitational effect through centrifugal force, will help reduce health risks to humans in space. The plans were revealed by Yosuke Yamashiki, director of the Center for Human Spaceology at Kyoto University, at a conference press release on July 5 at the same university, The Asahi Shimbun reports.

Designers plan to build a facility compatible with human life on the Moon called Lunar Glass in the form of an inverted cone that will be about 400 m high and that, in addition, will complete a rotation every 20 seconds, according to describes Sky News. They have also devised a similar facility called Mars Glass for Mars. Simulated rotational gravity is already used in high-gravity centrifuges to train astronauts and aviators.

In conjunction with these facilities, the researchers proposed an interplanetary transport system that maintains a gravitational force similar to that of the Earth during the journey. This is the “Hexatrack” system. The cars of the futuristic train, based on Earth, would be separated at injector stations and then inserted into a rotating hexagonal capsule which also generates centripetal force while traveling through space.

Researchers have presented all these systems and have also announced a joint study to achieve the objectives, although they do not expect that There are results immediately. In fact, they warn that the complete construction of the facilities will take around 100 years, although they hope to build a simplified version on the Moon by 2050. “There is no such plan in space development plans of other countries”, said Yamashiki.

The gravity on the Moon and Mars is one sixth and a third of that of the Earth, respectively. The proposal directly addresses a problem revealed by a study published earlier this month that found astronauts suffered significant bone loss in low-gravity environments. Astronauts had only regained about half of this bone loss a year after they returned to Earth, raising concerns about future missions to Mars and the Moon.

“As the idea of ​​living in space becomes more realistic, the problem of low gravity, which I intuitively realized when I was a child, is a challenge we must overcome,” said Takuya Ono, project associate professor and researcher principal in the Kajima corporation, to The Asahi Shimbun.
