Flash-Melted Glass from Chang'e-5 Reveals a High Levels of Iron on the Moon
Researchers analyzing lunar samples from the Chang'e-5 mission have discovered that meteorite impacts cause silicate liquid immiscibility. This process creates iron-rich nanodroplets within impact glass, providing new insights into space weathering on the Moon.
Why it matters
Understanding lunar surface chemistry helps scientists better interpret the history of the Moon and the impact of space weather on celestial bodies.
It might not seem like it, but the Moon is constantly being both sandblasted and baked. Its lack of a thick atmosphere allows micrometeorites to impact the surface at speed, and the solar wind isn’t held back either, baking the regolith with a constant flow of high-energy particles. These processes drive what is called “space weathering”, and it can drastically alter the physical and chemical properties of the lunar dirt over the course of billions of years. And we’re finally getting a better sense of what that means in practice thanks to two new papers from researchers at the Chinese Academy of Sciences and Peking University, which used advanced electron tomography and spectroscopic techniques to analyze samples returned from the Chang’e-5 mission to the near side of the Moon.
