Water Found on Moon

Scientists analyzing data from three separate space craft on missions to the Moon have concluded that water molecules are formed each day on the surface of the moon. While the water exists in tiny amounts in the soil, it is more than previously expected. A USGS scientist familiar with the findings estimated that if a ton of lunar soil was collected, as much as 32 ounces of water could be extracted. The hypothetical lunar hydrology cycle takes place during daylight when hydrogen ions arrive from the Sun and react with oxygen rich minerals in the soil to produce H2O and OH hydroxyl molecules. The molecular water is substantially evaporated by mid-day and re-formed in the evening as the lunar surface cools. But spectral analysis shows unequivocally that water is there. The implications for human colonization of the moon are immense. Scientist know now that there are valuable minerals on the moon, and the potential of water in usable amounts greatly simplifies lunar logistics and space flight to other planets in the system.
