On May 8, the Institute of Physics of the Chinese Academy of Sciences said the new research results demonstrate the feasibility of producing the building materials needed for a future lunar base.
According to a report by Chinese state media CGTN, research work by scientists from Institute of Physics (IOP) of the Chinese Academy of Sciences prove it materials on the surface of the Moon are feasible to produce materials, needed to build bases for humans in the process of conquering Earth’s satellites. By conducting systematic studies on lunar soil samples brought back by the Chinese Hang ga 5 mission, researchers have for the first time identified native fiberglass in soil samples on the planet’s surface.

Scientists have discovered the super long fiberglass, Formed from thermoplasticthe result of viscous fluids of molten material during meteorite impacts.
The IOP press release notes, studies using lunar simulation materials to make artificial glass fibers in the lab, materials to build human habitation facilities on the Moon in the near future. the future has already been made, so in this study, scientists eliminated the need to search for such materials.
The research team said: “Our results directly demonstrate that, Fiberglass can be produced in situ on the Moonas a basic basis for development technology for making fiberglass in space such as homogeneous optical fiber and reinforced structural fiberglass according to the construction requirements of future lunar habitation facilities. Various types of glass, discovered from moon rock carried by the Hang Bang 5 spacecraft to Earth, have been published in the National Science Journal. “National Scientific Journal” March 2023 issue.
This work provides a scientific basis for efforts to develop in situ manufacturing processes for glass materials and building structures based on the extraction and processing of lunar soil resources, the OP noted.
Besides fiberglass, the research team also discovered many types moon glass with different textures, types and origins.

On the barren surface of the moon, there are many types of lunar glass, created by various thermodynamically unbalanced processes such as volcanic eruptions, geological movements and meteorites that bombard the surface, can maintain material stability for billions of years. years.
Lunar telescopes played an important role in the exploration of the Moon by recording the “Important information on the formation of materials over geological time”the researchers said.
The team of scientists classified the glass into five categories based on the origin of the material: “volcanic glass, impact glass, adhesive glass, amorphous rim, formed by deposition and solar radiation“record the corresponding geological activities of the Moon.
The research team said: “Micro-impact products are as abundant as glass droplets or micron-to-nanometer-scale craters, clearly showing that the lunar topographic surface crust is continuously forming and changing through activity. frequent bombardments of micron-sized meteorites”.
The study sheds new light on the space-environment characteristics and the impact of the surface environment on the sampled lunar rocks, creating a basis for understanding the composition of the Moon’s material and the evolution of lunar rock. , said OP. topographic surface in space and time.
