Water shortage endangers lunar city plans
The article discusses the challenges of water resources in establishing permanent human colonies on the Moon. Studies indicate that the amount of water available in the polar craters—potentially up to a billion tons of ice—is insufficient to sustain massive cities for more than a century at best. Despite the availability of large-scale solar energy generation, water scarcity remains the biggest obstacle, as a city of a million inhabitants could deplete its resources quickly, even with highly efficient recycling systems. The studies suggest that solutions include improving recycling technologies, reducing consumption, and importing water from nearby asteroids. Additionally, ongoing exploration is crucial to search for additional water resources beneath the Moon's surface, as the deep layers may contain undiscovered quantities of ice that could support long-term settlement prospects.
