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.

據中科院物理研究所消息，我國科研人員在嫦娥五號月壤樣品中發現了多種類型的月球玻璃物質，其中包括首次發現的天然玻璃纖維，這可能為未來的月球基地建設提供重要支持。

此外，還發現了球狀、橢球狀、啞鈴狀等形狀的玻璃珠，以及氣孔構造的膠結質和流體形態的濺射物。

通過分析嫦娥五號月壤樣品中玻璃物質的形態、成分、微觀結構和形成機制，研究人員發現，玻璃材料的形成在月球表面有多種過渡方式。這些玻璃材料來源于頻繁的隕石撞擊造成的礦物熔化和快速冷卻。

隕石撞擊月球表面時，在較低的溫度和速度下形成了長徑比較高的天然玻璃纖維，與具有較低長徑比的玻璃珠的形成相比，這反映了月球表面較為溫和的微撞擊事件。
