Caption: Schematic showing the daytime cycle of hydration and rehydration on the lunar surface. In the morning, when the Moon is cold, it contains adsorbed water. By local noon, when the Moon is at its warmest, OH/H2O is lost. By evening, the surface cools again, and returns to a steady-state of hydration equal to that seen in the morning. Thus regardless of location or terrain type, the entire surface of the Moon is hydrated during some part of the lunar day.
