Mari Mountains in the review of the Japanese SELENE team
The new analysis confirms the presence of a large open lava tube in the lunar region of the Mariysk Gore, which can be used to protect colonists from dangerous conditions on the satellite surface.
Nobody spent more than 3 days on the moon, because space suits are not able to guarantee protection from extreme temperature fluctuations, radiation and meteorite attacks. The satellite does not have an atmospheric layer or a magnetic field, so there is no natural protection.
All data suggests that the safest habitat is internal, intact lava tubes. These are channels created by the passage of lava through a hard bark with the formation of the top cover. When the flow stops, the tunnel is exhausted and emptiness is created. It is important to understand how much we have and how strong they are to talk about building a lunar base in them.
JAXA analyzed radar data from the SELENE lava tube search engine. Near the territory of the Mari Mountains, we managed to find a decrease in the echo power, followed by a second echo peak, which hints at the presence of the tube. Two echoes correspond to radar reflections from the lunar surface and the ceiling of an open tube. And there may be several pieces. The SELENE radar system was not originally intended to search for lava tubes. Her task is to study the lunar origin and geological evolution. But the JAXA team decided to review the accumulated data in order to find the locations of the potential pipes. They knew that there are voids in the Mari Hills, but they did not know how far they were.
On Earth, there are also similar formations, but the lunar ones surpass them in size. To be fixed by a radar, the tube must be pulled out a few kilometers in length and 1 km in height. Everything suggests that a lava tube in the Mari Mountains can accommodate one of the American states.
