There moon it would ‘steal’ water from the Earth for billions of years, removing hydrogen and oxygen ions from its atmosphere which, when combined, would form permafrost and liquid water (hidden under the surface) for a total volume of about 3,500 cubic kilometers, equal to that of eighth largest lake in the world, Lake Huron in North America. To suggest this hypothesis, interesting for the sustenance of future human missions on the moonis a study published in Scientific Reports by researchers at the University of Alaska Fairbanks Institute of Geophysics.
According to the most accredited current models, most of the water moonre would have been brought by the impact of asteroids and comets and by the solar wind that carries hydrogen and oxygen ions. But the data collected by the main missions moonre of the space agencies of the United States, Europe, India and Japan, also seem to indicate a third possible source: the Earth’s atmosphere. The data shows the presence on the moon significant quantities of oxygen and hydrogen ions over the five days of the month moonre in which our satellite crosses the ‘tail’ of the Earth’s magnetosphere (that teardrop-shaped bubble that is created by the Earth’s magnetic field and which shields our planet from the flow of charged particles from the Sun).

The presence of the moon in the ‘magnetic tail’ of the Earth, temporarily alters some lines of the Earth’s magnetic field: those interrupted that are lost in space end up reuniting with their counterparts and in this way the ions that escaped losing themselves in space return to the Earth, hitting in their path there moon (which is not equipped with a protective magnetosphere). “It’s as if there moon was in the shower, with a shower of ions returning to the Earth that end up falling on the surface of the moon“explains study coordinator Gunther Kletetschka.
