How So Much Water? Some Ideas...A stream of charged hydrogen ions carried from the sun by the solar wind. One possible scenario to explain the new finding of water on the lunar surface is that during the daytime, when the moon is exposed to the solar wind, hydrogen ions liberate oxygen from lunar minerals to form OH and H2O, which are then weakly held to the surface. At high temperatures (red-yellow) more molecules are released than adsorbed. University of Maryland/F. Merlin/McREL
From Discovery News:
Shattering a long-held belief that Earth's moon is a dead and dry world, a trio of spacecraft uncovered clear evidence of water and hydrogen-oxygen molecules throughout the lunar surface.
"There's no question that there is OH [hydroxyl, which is made up of one hydrogen atom and one oxygen atom] and H2O on the moon," University of Maryland senior research scientist Jessica Sunshine told Discovery News.
