LONDON, May 16 (Xinhua) – Measurements from the Chang & e-4 mission in China on the other side of the moon have revealed the presence of lunar mantle material at the landing site, according to a study online Wednesday in the journal is published Nature.
The Chang & e-4 probe reached the Von Karman crater in January 2019 and deployed the Yutu-2 rover to explore the South Pole Aitken basin on the other side of the moon.
Previous global remote sensing missions from an orbit have agreed with the idea that "the best candidate for excavating moon's mantle materials was the huge South Pole Aitken basin that, given its size, should have entered the mantle through the moon's bottom" , Patrick Pinet at the French research institute for astrophysics and planetology, Xinhua told by email.
The detailed structure of the moon's mantle has been avoided for years by researchers. Scientists have focused their efforts on the impact craters, because the events that led to their creation have invaded the crust into the moon's interior, dug out parts of the mantle and spread it on the surface.
Based on the first observations of Yutu-2 & Visible and Near Infrared Spectrometer, a team led by researchers from the Chinese Academy of Sciences led the presence of low calcium pyroxene and olivine minerals, which may arise from the upper mantle, to the surface.
They argued that this material was excavated from below the South Pole-Aitken basin bottom by the nearby Finnish impact crater.
The characterization of the mantle of the lunar mantle is "a very important step to take", because it allows researchers to present better models of the evolution of the lunar interior and "related questions about the moon of lunar magma and coagulation / cooling it, "Pinet said an accompanying article commenting on the latest findings from the Chinese team.
To further confirm the findings, it is still necessary to take a sample from the rocks to the earth for analysis, according to Pinet.
