Vertical lava tunnels will help build long-term bases on the Moon and entire cities, Satoshi Kodaira, a scientist at the Japanese Institute of Radiological Research.
In the coming years, some states, including Japan, are planning to start coming to grips with the exploration of the moon. In this regard, questions arise about the possibility of creating settlements there for long-term residence.
The researchers took part in scientific work, the result of which was materials about the tunnels formed after the eruption of volcanoes in the bowels of the Moon. They will become reliable protection against radiation and meteorites.
According to recent observations, it became clear that the radiation level on the lunar surface is higher than on the ISS, and I think this creates a problem not only for humans, but also for equipment, interferes with long-term human activity, and in some cases makes it impossible.

According to him, radiation is pressing from all sides in open space, and this is even more dangerous, as is the case with the Gateway project.
Lava tunnels, according to research by the Japan Space Agency JAXA, are tubes that usually run almost vertically. Their width is at least 100 meters, and their depth can reach 50 kilometers.
At the same time, space radiation and meteorites pose a great danger to people on the lunar surface, while placement in lava channels provides protection from them. In addition, the temperature in volcanic tunnels practically does not change.
As reported recently by the Kyodo agency with reference to JAXA, Japan plans to build a fuel production plant on the moon by 2035 in order to use it in large-scale development of the Earth’s satellite. To reduce the cost of transporting fuel from Earth by about 2035 at the south pole of the moon, where ice deposits are supposed to be found, the Japanese want to build a plant where the water obtained there will be split into oxygen and hydrogen, and produce fuel.
