[First results from #DORN on the #Moon] The recovery of samples of #regolith and lunar rocks, coupled with the analysis of #surface gases by the #DORN instrument, has enabled the scientists involved in the #ChangE6 mission to identify the occurrence of two volcanic episodes on the far side of the Moon, 4.2 and 2.8 billion years ago. For the record, the samples brought back by the #Apollo and #Luna missions from the visible side of our satellite attest to a single volcanic event, dating back more than 3 billion years.
Further analyses are underway, which will “refine previous observations made by remote sensing, which have shown that the far side of the Moon is different, in terms of #geophysics (differences in crustal thickness, for example) and the chemical and mineralogical composition of the rocks, from that of the visible side”, explains Pierre-Yves Meslin, astronomer at IRAP.
[Premiers résultats de #DORN sur la #Lune] La récupération d'échantillons de #régolithe et de roches lunaires, couplée à l'analyse des #gaz en surface par l'instrument #DORN, a permis aux scientifiques impliqués dans la mission #ChangE6 d'identifier la survenue de deux épisodes volcaniques sur la face cachée de la Lune, voici 4,2 et 2,8 milliards d’années. Pour mémoire, les échantillons rapportés par les missions #Apollo et #Luna de la face visible de notre satellite attestent d'un seul événement volcanique, daté de plus de 3 milliards d'années.
D'autres analyses sont en cours, qui permettront « d’affiner des observations antérieures réalisées par #télédétection qui ont montré que la face cachée de la Lune est différente, en termes de #géophysique (différences d’épaisseur de la croûte, par exemple) et de composition chimique et minéralogique des roches, de celle de la face visible », explique Pierre-Yves Meslin, astronome à l'IRAP.

Weight of the lunar samples brought back by China‘s Chang'e-6 probe = 1935.3 grams. It is slightly less than the 2 kg goal, since Chang'e-6's drill could not penetrate beyond 1 m due to some rocks below the lunar surface.
Chang'e 6 chief designer Hu Hao revealed that the soil is stickier and has clumps compared to Chang’e-5’s sample.

The mission has significance for the #MoonRace between #China and the #UnitedStates
This was not China's first robotic mission to return a few pounds of dust and pebbles from the lunar surface—that came with the Chang'e 5 mission in December 2020. However, this was the first time any space program in the world returned material from the Moon's far side, and it looks like #Change6 mission succeeded.
