The research study is a collaborative effort in between Kyoto University and the Kajima Corporation (one of Japans earliest and largest building and construction companies). The statement was made during a press conference covered by Kansai television NEWS and shared via their Youtube channel. Here, Professor Yosuke Yamashiki of Kyoto University and Takuya Ohno– the head of the Architectural Design Department at Kajima Constructions Kansai Branch– shared a video of their proposed “synthetic gravity” center” for residing on the Moon and Mars.
Working and living in space for prolonged durations of time presents a number of difficulties. If mankinds future truly lies in area, we should devise services to this concern in advance.
A popular idea is to create rotating environments in area that replicate synthetic gravity, like the Pinwheel Station or the ONeill Cylinder. Another proposal by a group of Japanese scientists calls for something bolder: a rotating habitat on the Moon! On July 5th, representatives from Kyoto University and the Kajima Corporation (one of the oldest and largest building companies in Japan) announced that they would be partnering to conduct a study on this concept and how it might make humanitys strategies for surviving on the Moon and Mars a reality!

Thanks to numerous experiments including long-lasting stays aboard the ISS, which includes NASAs popular Twin Study, it is established that astronauts will experience a loss in muscle mass and bone density. Other noted results include changes in cardiovascular health, organ function, vision, psychological impacts, and gene expression.
This should be addressed if astronauts and regular folk hope to live on the Moon, where the surface area gravity is 16.5% (0.165 g) that of Earth. On Mars, where the surface gravity is approximately 38% (0.385 g) that of Earth, the scenario is a little much better– but by no methods ideal.
This is the idea behind the center understood as “Lunagrass,” which would allow astronaut crews to live and work in simulated Earth gravity. As Professor Yamashiki explained:
” Mars and the Moon are much smaller (surface gravity) than Earth. If human beings will eventually live in these places … It is not known if mammals can breed and grow typically in a space with low gravity such as the moon, I question. The gravity inside Lunagrass is the same as that of the earth, and it is possible to offer birth, and if you live here, you can preserve a body that can return to the Earth at any time.”

As the video reveals, the principle resembles an ONeill Cylinder, other than that it stands and turns on its side and is tapered towards the bottom (producing a funnel shape). The “funnel” is supported by a large lattice structure that expands at the base to disperse the centers weight over a bigger area. Winding around the base structure is a track showing a high-speed train responsible for transport from the funnel to the lunar surface or in between points inside.
Inside the funnel, we see bodies of water, landmasses with greenery and trees, what appear to be drifting structures (the brown squares), and a transportation network that allows individuals to take a trip throughout. The simulated individuals in the video are revealed strolling along the “walls” as if it were no various than walking on the Earths surface area (there are even motorboats driving on the water!) At the base of the funnel, which is less topic to centripetal force, there is a standing body of water with more boats cruising around.
Other ideas attended to in the presentation include an Earth-Moon transportation (and even an interstellar one) that would rely on the same concepts to mimic artificial gravity while in area. These are referred to as the “Luna Beagle” and “Space Express,” respectively. The animation shows what the former would appear like, a hexagonal-shaped vessel with modules extending from a main spoke that rotates to provide artificial gravity for all those inside. Said Professor Yamashiki:
” Also, research study on transportation techniques using “artificial gravity” has started. The idea is to produce a Luna Beagle that runs on the Moon and a Space Express that moves in between stars … Im attempting to ensure the exact same gravity (1G) environment as the Earth while moving.

Alas, one cant help however raise the apparent concern of expenses and the inevitable engineering difficulties of constructing this kind of structure on the Moon. During the presentation, the topic of in-situ resource utilization (ISRU) and how this structure would be built did not come up. Would it be assembled on Earth or in area, then sent to the Moon, or put together on-site using regolith and other lunar resources? Would the job be dealt with by autonomous robots, human crews remotely-operating equipment on the surface area, or a mix thereof?
As Ohno confessed, the Lunagrass idea is “a dream story” at this moment and not an actual objective architecture. However, he included, it is a serious idea and one that might effectively be feasible in the future. As humanity embarks on a renewed period of space exploration that consists of strategies for long-term habitats on the Moon and Mars, “dream story” ideas like this play a crucial role.
“If possible, I desire to go to the Moon. I want to realize the principle on the Moon in some way in 2050.”
