UAF: tons of water hit the moon from the Earth's atmosphere

A new study estimates that the Moon's polar regions may contain up to 3,500 km³ of surface eternal

permafrost or underground liquid water. It came from ions that were part of the Earth's atmosphere. This is a volume comparable to Lake Huron in North America, the eighth largest lake in the world.

According to the researchers, they calculated this volume of water, assuming that only 1% of emissions from the Earth's atmosphere reach the Moon.

It is generally believed that most of the lunar watergot there from asteroids and comets that collided with the moon. Most of these celestial bodies crashed into the moon about 3.5 billion years ago, when the solar system was about 1 billion years old.

Scientists also hypothesize that the source of the ions is the solar wind. It carries oxygen and hydrogen ions, which may have combined and settled on the moon in the form of water molecules.

The authors of the new work suggest that the ionsHydrogen and oxygen enter the Moon as it passes through the Earth's magnetotail. This happens about five days a month. The magnetosphere is a teardrop-shaped bubble of the Earth's magnetic field that shields the planet from a continuous stream of charged solar particles.

The research team usedgravity data from NASA's Lunar Reconnaissance Orbiter to study the polar regions, as well as several large lunar craters. They noted that there are anomalies in the underground measurements of impact craters - this indicates that there is liquid water or ice inside.
