Caption: Schematic showing the stream of charged hydrogen ions carried from the Sun by the solar wind. One possible scenario is that during the daytime, when the lunar surface is exposed to the solar wind, hydrogen ions liberate oxygen from lunar minerals to form OH and H2O, which are then adsorbed and weakly held to the surface. At high temperatures (red-yellow) more molecules are released than adsorbed. When the temperature decreases (green-blue) OH and H2O accumulate.
