3. Scientists estimate that the eight largest craters on the Moon contain approximately 34 million tons of water, located primarily in permanently shadowed regions near the lunar poles. (Plus JEDEN DEŇ, News)
4. Researchers state that water on the Moon is likely mixed with lunar material and toxic chemicals rather than existing as pure ice cubes that can simply be melted and drunk. (Plus JEDEN DEŇ, News)
