China’s Chang’e-6 mission has provided groundbreaking insights into the Moon’s far side, unveiling its volcanic history and key differences from the near side, according to a study published on Friday. The findings highlight two significant volcanic events that occurred 2.8 billion and 4.2 billion years ago on the far side, shedding new light on its geological activity.
The study, conducted by researchers from the Chinese Academy of Sciences, analyzed 108 basalt fragments collected by Chang’e-6. Most samples were dated to about 2.8 billion years ago, revealing volcanic activity that was previously undetected on the far side of the Moon. One fragment, dating back to 4.2 billion years, is the oldest lunar sample ever returned with a precisely known age.
A separate study in Science explores the differences between the Moon’s two hemispheres, particularly the far side’s volcanic activity. Researchers discovered that low-titanium rock samples, which are about 2.83 billion years old, point to ongoing volcanic eruptions during that time. This finding challenges the long-held belief that the far side’s thicker crust prevents volcanic eruptions.
These studies enhance our understanding of the Moon’s diverse geological history and raise new questions about the factors influencing volcanic activity on the far side, where lava has not flooded the surface as extensively as it has on the near side. The Chang’e-6 mission continues to play a crucial role in unlocking the Moon’s mysteries.
