Scientists Discover Molecular Water in Lunar Soil for the First TimeChinese scientists have identified a new water-bearing mineral, ULM-1, in lunar soil samples brought back by the Chang'e-5 mission, marking the first confirmation of crystalline molecular water in lunar soil. This mineral, characterized by high water content and stable properties, suggests that persistent water sources may exist in sunlight-exposed regions of the Moon.

Scientists Discover Molecular Water in Lunar Soil for the First Time

 

Chinese scientists have identified a new water-bearing mineral, ULM-1, in lunar soil samples brought back by the Chang'e-5 mission, marking the first confirmation of crystalline molecular water in lunar soil. This mineral, characterized by high water content and stable properties, suggests that persistent water sources may exist in sunlight-exposed regions of the Moon.

The discovery holds significant implications for lunar water resource development and the establishment of sustainable lunar bases. It challenges previous notions about water distribution on the Moon, indicating that usable water might be more accessible than once thought—potentially reducing reliance on Earth-supplied resources for future lunar exploration and habitation.

 

Researchers note that ULM-1’s stability under lunar conditions opens new avenues for studying the Moon’s hydrological history and developing technologies to extract water for human activities, from life support to fuel production. This breakthrough reinforces China’s growing role in advancing lunar science and paves the way for more ambitious space exploration endeavors.
