China’s Chang’e-6 mission returned the first samples collected from the Moon’s far side. Analysis dates basalt from the South Pole–Aitken basin to about 2.8 billion years ago and reveals a chemical composition that may help explain differences between the lunar hemispheres.
TLDR: Chang’e-6 brought back the first samples collected from the Moon’s far side in June 2024. Researchers dated basalt fragments to about 2.8 billion years old and found a composition low in several heat-producing elements. The results offer new evidence about lunar volcanism and the Moon’s contrasting hemispheres.
For the first time, scientists have analyzed rocks collected directly from the Moon’s far side. China’s Chang’e-6 mission brought 1,935.3 grams of lunar material back to Earth in June 2024, after landing in the South Pole–Aitken basin, an enormous impact crater. Laboratory dating of basalt fragments from the samples places a major episode of volcanic activity in the region at about 2.8 billion years ago. The result gives researchers a rare, physical record from a hemisphere that had previously been studied only from orbit or through meteorites whose original locations were uncertain. Returned rocks also allow direct mineral and isotope tests unavailable from orbit.
The landing site lies within a vast basin more than 2,400 kilometers across, formed by an ancient collision. The spacecraft collected soil and rock near the crater Apollo, using a robotic arm and a drill before an ascent vehicle carried the material to orbit and a return capsule delivered it to Earth. Researchers separated tiny fragments from the returned samples and used radiometric methods to estimate their ages. A study published in the journal Science reported an age of roughly 2.83 billion years for the basalt, evidence that lava flowed across this part of the lunar surface long after the basin itself formed. The basin’s scale makes it a key target for investigating the Moon’s earliest impacts and crust.
The date matters because most lunar samples collected during the Apollo and Luna missions came from the near side. Those rocks showed extensive volcanism, but their distribution left scientists unsure whether the far side followed the same timeline. Chang’e-6 provides the first direct test from the far side and reveals that volcanic activity continued there into the Moon’s middle history. The finding does not mean the entire far side was active at that time: the samples represent a small collection from one landing area, and the Moon’s volcanic history varied between regions.
Chemical measurements also point to a distinctive source for the lava. The basalt is low in certain heat-producing elements, including potassium, rare-earth elements and phosphorus, often grouped together by researchers as KREEP. That composition suggests the magma came from mantle material with less of these elements than sources associated with many near-side basalts. The difference offers a clue to why the near side has broad dark volcanic plains while much of the far side is more heavily cratered and has a thicker crust. These elements can generate heat through radioactive decay and influence mantle melting.
One proposed explanation is that the South Pole–Aitken impact altered the Moon’s deep interior. The collision may have heated or mixed mantle material, affecting where later melting could occur. But the Chang’e-6 samples alone cannot establish that the impact caused the observed chemistry or explain all the differences between the hemispheres. Scientists will compare the returned fragments with lunar meteorites, orbital measurements and samples from other missions, while checking how much the collection site represents the wider basin. Impact effects remain difficult to isolate.
The material’s scientific value extends beyond its age. Researchers can examine minerals, isotopes and traces of impact history in a controlled laboratory, with more precise instruments than can be carried on a lander. The samples may help refine models of lunar formation and the evolution of rocky worlds, while providing ground truth for remote sensing of the far side. Further studies and future sample-return missions will be needed to determine how widespread this volcanism was and what processes shaped the Moon’s two contrasting hemispheres.
