Natural Glass Discovered In Lunar Samples

Chinese scientists have discovered multi-ple types of glass material in lunar samples re-trieved by the Chang ’e-5 mission， includingnatural fiberglass which has been found for thefirst time and could provide important supportfor future lunar base construction， according tothe Institute of Physics under the Chinese Acad-emy of Sciences.

The material， which includes spherical， el-lipsoidal and dumbbell- shaped glass beads aswell as colloidal items with a porous structureand sputtering material in fluid form， have alsobeen found.

By analyzing the morphology， composi-tion， microstructure and formation of the mate-rial， which originated from mineral melting andrapid cooling caused by meteorite impacts onthe lunar surface， researchers found there weremultiple ways the material was formed.

The glass with a higher length-to-diameterratio was formed under lower temperatures andspeed when a meteorite impacted the lunar sur-face， reflecting milder impact events comparedwith the formation of glass beads which have alower length-to-diameter ratio.

据中科院物理研究所消息，我国科研人员在嫦娥五号月壤样品中发现了多种类型的月球玻璃物质，其中包括首次发现的天然玻璃纤维，这可能为未来的月球基地建设提供重要支持。（剩余208字）
