Scientists from China, Germany and the United States have found in the samples of the lunar soil delivered by the Chang’e 5 apparatus, fragments with an “exotic” chemical composition. The results of the preliminary analysis of the soil scholars submitted on the European Congress on the Sciences of Planets.
Delivered in December 2020 samples are the youngest of ever delivered from the moon for laboratory analysis: the age of a geological area where the device lifted, does not exceed two billion years. 90 percent of the apparatus assembled 1.7 kilogram of the soil is most likely occurring from the place of its landing on the Earth’s satellite – the peak of the Ryumker – and represent the lunar marine basalt – visible from our planet “dark” surface sections. Among the remaining ten percent are the remnants of meteorites and vulcanic glass balls, scientists from the Chinese Geological University are noted.
together with colleagues from Brown and Westphalian universities, they studied granular inclusions and found that in their composition they are identical to the materials from Maran canyons and Sharpe – located at 230 and 160 kilometers from the place of gravestonia. The young age of breeds also allowed to narrow the search for shock crater, of which the fragments of meteorites occur – it turned out that most of them come from Crater Garpal. Some of the fragments could be brought to the place of landing of the module from a distance of 1300 kilometers.
The Chang’e 5 mission became the first returned lunar Chinese mission and the first in 44 years old – with the Soviet “Luna-24” in 1976 – the samples of the lunar soil on Earth. China has become the third country who managed to do it – after the USSR and the USA
