Asteroid-impact mystery unlocked by the first samples ever brought back from the Moon's far side

The Chang'e-6 mission

According to Radiotrek — Світ: China's Chang'e-6 spacecraft has achieved a historic first by bringing rocks from the far side of the Moon back to Earth. The material is between roughly 4.33 billion and 1.13 billion years old, and studying it has revealed a steady decline in asteroid collisions over billions of years. Instead of one overwhelming asteroid shower in the early solar system, the evidence suggests that leftover orbital debris was gradually cleared after planets formed.

By analyzing small fragments, researchers identified impact records stretching across more than three billion years. The sustained decrease in bombardment intensity gives scientists a more accurate view of the solar system's evolution. Earth is a poor archive for such ancient events because erosion, volcanoes, and tectonic plate movements have destroyed most traces. The Moon, by contrast, preserves this record, making it a crucial object for reconstructing geological history.

Why this mission matters

Chang'e-6 stands as the first mission to return samples from the lunar far side, giving researchers an unprecedented resource for investigation. The far side retains evidence that vanished from Earth billions of years ago, and these samples may reshape our understanding of planetary evolution and the early solar system. For scientists, the Moon acts like a time capsule, and these specimens finally let them read a part of that story.

The returned material does more than illuminate lunar history; it also helps explain the broader processes that shaped our solar system. This could guide future studies of other planetary bodies and offer clues about how planets form and change over time. The achievement also highlights the importance of global cooperation in space exploration and scientific discovery.

As scientists continue to analyze the groundbreaking samples from the Moon's far side, the release of an ultra-detailed lunar atlas by China provides an invaluable resource. This atlas complements the findings of the Chang'e-6 mission, offering insights into the Moon's geological features and enhancing our understanding of its history and the solar system's evolution.
