Furthermore,
Moon undergone greatest shock solar:
The samples of the Chinese lunar mission Chang’e 6 show that the moon experienced considerable. Similarly, impacts during its training. Furthermore, The comparisons of the rocks collected by the Apollo missions with those of the hidden face of our satellite. Consequently, reveal how cataclysmic shocks were.

On the one hand, large plains. Nevertheless, On the other, a soil strewn with thousands of craters. Consequently, The two sides of the moon are extremely distinct. Furthermore, the part that is invisible to us is much less known than that which we see at night.
But everything has been changing since 2024 with the Chang’e 6 mission which brought back samples from this famous “hidden. Furthermore, face of the moon”. However, The rocks came from the lunar south pole. it was a question of basaltbasalt resulting from the cooling of the makemake.
A team of researchers from the University of Beijing analyzed these samples. has made an interesting discovery: the rocks recovered on the surface have some common characteristics with the coatcoat Lunar, but also with the visible side of the moon.

The memory of a monumental shock – Moon undergone greatest shock solar
The rocks were taken from the basin Stubborn And date from 2.8 billion years ago. This area is known to be the largest impact pool of the entire solar system. About 2,500 kilometers in diameter, it is even larger than Hellas Planitiaon Mars. The shock. at the time, was so important that the impactor could have crossed the crustcrust and cause a surge of magmamagma from the depths of the moon. It is still not known what the nature of the impact of the body is thus struck by the moon. we know neither his size, nor the angle with which the shock took place.
Be that as it may. the chemical composition on the visible side of the moon is different from that of the hidden side. There are in particular radioactive isotopes of potassium, uranium and thoriumthoriumwhich maintain this warmer side than the other, even today. This partly explains the differences between the two faces and that is why the basin Stubborn is so important.
After the Moon, Mars? Mercury?
The shock that produced it was so violent that the underground magma was ejected over hundreds of kilometers. and this materialmaterial found itself on the surface, at the mercy of the space vacuum, which considerably changed its composition. In these dark side samples, the typical elements on the lit side were found.
Clearly: the rocks are very similar to those that were harvested during the Apollo 12 mission. on the other side of the moon. Which can mean two things:
- Either the magma contained in the lunar coat was identical on both sides when it was crystallized when leaving the ground during the shock.
- Either the impact caused a heatheat such that these elements were torn off from the rocks and found themselves on the surface. This would mean that the impact which caused the creation of the basin considerably turned the internal composition of. the Moon.
Study authors. published in Natureadd: ” These discoveries around impacts could mean that similar events may have taken place moon undergone greatest shock solar on impact basins of more than 1,000 kilometers discovered elsewhere in the Solar systemSolar system. So. Mars, but also MercureMercure et VenusVenus could be studied more closely thanks to the samples of the Chinese probe Chang’e 6.
