Recently, the world's first mineralogical analysis report on samples from a magnesium ring on the Moon's far side was released by Shandong University. This research focuses on a special area within the Moon's South Pole-Aitken (SPA) Basin known as the "magnesium-rich pyroxene ring." With the Chang'e-6 mission returning lunar soil samples from near this region to Earth, researchers have for the first time unveiled the true nature of this enigmatic location. This report is not only the world's first research on the mineral composition of a lunar magnesium ring based on samples from the Moon's far side, but also provides crucial support for understanding the Moon's internal structure and composition, impact and thermal evolution history, and calibrating lunar orbital remote sensing data.
