The analysis of lunar samples of 2.8 billion years collected in 2024 by the Chinese mission of Chang’e-6 gives new knowledge about the formation of the moon and the origin of asymmetry between two persons. The results published on Wednesday in the journal NatureThey indicate that the rocks selected by the Chinese mission were very impoverished in such elements as strontium and neo -in -and -in -and -and -dime, if we compare them with the compositions that, as we hope, you have a moon mantle, and indicate a possible influence on the evolution of the satellite of the effects of giant objects on its surface.
Observations of the moon revealed differences in the thickness of the bark, volcanic activity and the chemical composition of breeds between the visible face and the hidden face of the moon. However, the origin of these differences was the subject of the debate.
In 2024, the Chinese Chang’e-6 probe brought basalt samples (rocks formed from the cooling of lava) of the Eitken basin, on the south pole and on the hidden face of the moon, which, together with the samples brought by the missions of Apollo, allowed researchers to study the differences between both hem.
Differences with Apollo Stones
The team led by Wei Yang, from the Academy of Sciences of China, analyzed the isotopic composition of the samples of volcanic breeds of the Chang’e-6 mission and compared them with the samples obtained during the missions of Apollo of the visible person.
The authors found that the cliffs of the southern pool of the pole pole shared some characteristics with the mantle of the visible face, but they seemed to take away the part of the lunar internal interior, which was already devoid of molten material. These properties suggest that the basalt could be formed from deep rocks (from the mantle), already poor in some elements that would be removed from the mantle with the geological processes that occurred during the magma phase de la Moon Ocean, or on the influence that gave rise to the Aiten pool.
The authors conclude that the samples caused by the Chang’e-6 mission provide means to study the early formation of the lunar mantle, and that subsequent studies can provide more information about the processes that underlie the differences between the visible person and the hidden face.
China, a full car
“For the first time, we have new accurate data that allow us to deepen the composition of the lunar mantle and help us understand the asymmetry of our satellite,” says Hesus Martinez Frias, an expert on planetary geology and astrobiology of the CSIC at the Institute of Geosinty. In his opinion, this is one of the most interesting studies from the petrological and geochemical point of view (mainly isotopic) conducted on the moon in recent years. “It should be recognized that China goes to the full car in the field of space research, especially from space near the ground, and its initiative and mission to the moon are evidence of this.”

“What this work puts for us is the question: do we have an impoverished lunar mantle from its most initial states with similar characteristics on the entire moon or that impoverishment is associated with subsequent processes, such as great influences?” Summies Sundom Martinez Frias. The expert believes that this result opens the second opportunity and very well complements the geophysical data obtained recently with the help of the Grail probes, always very careful, because they have analyzed only 16 samples.
Naum Mendes Chazarra, a geologist and a disseminator, believes that this study gives us a new vision of the history of the moon, which should be taken into account when it comes to understanding how the asymmetry was formed, which we see even in the naked eye between his visible face and his hidden face. This difference should not have arisen during the cooling of the magician -ocean, but it may be the result of subsequent processes, he notes. “The authors suggested that great influences have the ability to change various geodynamic and geochemical processes that occur inside planetary bodies, contributing to us a new vision of how the planets develop and how they have become what we see today.”
