The Chang’e-6 mission, however, marks the first time humanity has ever successfully collected samples from the Moon’s far side, returning 1,935.3 grams of precious material.
The landing site for this sampling mission was located in the South Pole-Aitken basin on the far side, specifically at the edge of the Apollo impact crater, an area where the lunar crust is extremely thin, potentially revealing primordial materials from the early impact basins. Particle analysis shows a bimodal distribution of grain sizes, indicating that the samples may have undergone mixing from different sources.
The study indicates that the Chang’e-6 samples contain not only basalt that records the history of volcanic activity on the Moon, but also non-basaltic materials from other regions.
