Chang'e 6 Finds Moon's Far Side Surprisingly Dry

Analysis of lunar samples returned by China's Chang'e 6 mission suggests the far side of the moon may be drier than the near side. Scientists examined 578 particles from the South Pole-Aitken basin, estimating water abundance at less than 1.5 micrograms per gram—lower than previous near-side findings. While more samples are needed for conclusive evidence, the dryness could be linked to the basin's formation or variations in water distribution. This finding is unlikely to significantly alter NASA's plans to land astronauts near the lunar south pole, where abundant water ice is expected to support future missions.
