The presence of water in its mantle is a remnant of its original formation accretion.

The issue of water formation in the oceans then became a bit more complicated because we asked ourselves the question of the exact initial amount of water brought in by accretion, for example in the form of comet and finally how this water was finally stored in the bowels of the earth. In this regard, an interesting theory was recently proposed by the great Russian physicist and crystallographer Artem Oganov and his colleagues.

Volcanoes and the lunar atmosphere

The earth is not the only rocky body in the world solar system where significant volcanic activity has taken place. This is unmistakably the case. A moon with a small “L” is a planet’s satellite. For example, Phobos and Deimos are the two moons of the planet Mars.

We can therefore question the existence of an initial lunar atmosphere, which would have been created by outgassing and containing some water vapor even during the first hundred million years of the moon.

One can also ask the question of the moon’s initial water content. It is problematic in the framework of the model with a huge impact that gives birth to our satellite after a violent collision between the young Earth and a planet the size of Mars, the famous one Theia. The moon would then have actually been formed by accretion of debris from the collision at high temperatures. So we could expect a priori to a moon without water because it results from a massive evaporation of a very hot matter. But it appears, according to the study of lunar rocks, that the water content of the lunar mantle is not as low as one might think.

Out of numerical simulations conducted by a group of researchers from the Department of Science astrophysics and planetary systems (APS) and the laboratory for The theories established by physics apply within a well-defined framework.

The results obtained were published in an article by The Planetary Science Journal and they suggest that there are significant ice deposits resulting from condensation of the vapor produced by the large lunar flares found at the lunar poles 2 to 4 billion years ago.

Transient atmospheres created by large eruptions

A few years ago, planetary scientists got out Lunar and Planetary Institute von Houston had shown that each time these eruptions could have created a transient atmosphere of carbon monoxide poisoning

The Boulder researchers refined this scenario by showing that the eruptions of tens of thousands of volcanoes create huge rivers and lakes wash between 2 and 4 billion years would have allowed for the repeated formation of atmospheres that could last about 2,500 years before disappearing into space through evaporation.

The simulations then show that about 41% of the water vapor emitted by the eruptions in the Moon’s famous polar regions could have condensed at the level of certain craters, in part in the eternal shadow for billions of years. The amount of water trapped could then reach 8.2×1015 kg.

Their existence has been speculated for decades insoles of ice, which may also have formed, as originally thought, from the condensation of water vapor released by cometary impacts on the Moon during its first billion years, since bombardment of small celestial bodies was more important than it is today.

The ice reserves of volcanic origin could be less than 5 to 10 meters regolithwhich should not pose a serious problem for future lunar settlers who could then also use this water to grow plants or build up reserves of fuel and fuel, fuel and combustion

Future colonists could then drink water from lunar volcanoes, provided that it is not also or mainly comet water.
