New lunar samples confirm the Moon was once entirely covered by a molten "magma ocean."
A new study based on lunar samples collected by China's Chang'e-6 mission confirms the hypothesis that the Moon was once entirely covered by a molten "magma ocean" shortly after its formation.
The mission, conducted in 2024, was the first to sample the Moon's far side, retrieving materials from the South Pole-Aitken Basin.
The research, published in Science, reveals similar basalt compositions on both sides of the Moon, supporting the magma ocean model.
This model suggests that the Moon experienced a global melting event, forming a vast magma ocean that cooled and crystallized to form the lunar crust and mantle.
The study also indicates that the impact event creating the South Pole-Aitken Basin may have altered the Moon's early mantle.
