Chinese Mission Provides Evidence Suggesting Global ‘Magma Ocean’ on Early Moon
The Discovery that’s Changing the Way We Think about the Moon’s Origin and Evolution
The latest findings from China’s Chang’e-6 mission are sending shockwaves throughout the scientific community, providing conclusive evidence that the moon was once covered in a "magma ocean" during its early stages. This groundbreaking discovery is set to revolutionize our understanding of the moon’s origin and evolution, and has significant implications for Earth’s own history.
A Global Magma Ocean: The Hypothesis Confirmed
For decades, scientists have theorized that the young moon was once covered in a vast, global magma ocean. This molten ocean, formed around 4.5 billion years ago, is thought to have played a crucial role in the moon’s early development. The new study, led by a joint research team from the China National Space Administration (CNSA), has now confirmed this hypothesis using samples collected by the Chang’e-6 mission.
The Chang’e-6 Mission: A Vehicle for Discovery
The Chang’e-6 mission, launched in 2024, successfully retrieved 1,935.3 grams of lunar samples from the Apollo Basin within the South Pole-Aitken (SPA) Basin. Two grams of these precious samples were allocated to a research team at the Institute of Geology, Chinese Academy of Geological Sciences, for further analysis.
The Findings: A Global Magma Ocean
The research team has discovered that the composition of basalt, a type of volcanic rock, from both the far and near sides of the moon is similar. The basalt in the Chang’e-6 samples is approximately 2.823 billion years old, and its characteristics support the lunar magma ocean model. The study suggests that the impact event that created the SPA Basin may have altered the moon’s early mantle, as explained by Liu Dunyi, a senior researcher at the institute.
Unlocking the Moon’s Secrets
The lunar magma ocean model proposes that the newborn moon underwent a global melting event, creating a vast magma ocean. As this ocean cooled and crystallized, less dense minerals floated to the surface to form the lunar crust, while denser minerals sank to form the mantle. The remaining melt, enriched with incompatible elements, formed the KREEP layer, a crucial component of the moon’s early development.
The Far-Side Samples: A Game-Changer
However, until the Chang’e-6 mission, all lunar samples came from the moon’s near side, leaving the model incomplete. The far-side samples have now filled in this gap, providing a more comprehensive understanding of the moon’s early evolution.
Implications for Earth’s History
The discovery of a global magma ocean on the early moon has significant implications for Earth’s own history. It suggests that the early solar system was a chaotic, violent place, with massive impacts shaping the fate of the moon and other planets. Further research into the moon’s impact history will shed light on Earth’s own past, which has been obscured by tectonic activities.
A Commitment to Lunar Research and International Cooperation
The CNSA has emphasized its commitment to advancing lunar research and sharing scientific findings with the international community. The Chang’e-6 mission marks a new era in lunar exploration, with China playing a leading role in unraveling the mysteries of the moon.
The Implications are Far-Reaching
The discovery of a global magma ocean on the early moon opens the door to a deeper understanding of the moon’s origin and evolution. It also highlights the importance of international cooperation in space exploration, as scientists around the world continue to unravel the secrets of the moon and our solar system.
What’s Next?
The research team plans to delve deeper into the moon’s early impact history, with a focus on the Chang’e-6 sampling site, which may contain records of early solar system impacts. The discovery of a global magma ocean is a watershed moment in lunar research, and we can expect significant breakthroughs in our understanding of the moon and our place in the universe.
