Chang'e-5 mission samples reveal high iron content in lunar glass

Flash-melted lunar glass from China's Chang'e-5 mission reveals high concentrations of pure metallic iron. Analysis of impact glass beads showed silicate liquid immiscibility, separating molten iron-rich nanodroplets. These droplets, frozen in place, can comprise up to 30% of some layers. This discovery could significantly impact lunar resource utilization, with estimates suggesting up to 7.1% pure iron in mature impact-glass regions.
