Whether the hydration is molecular water (H2O) or other hydroxyl (OH) compounds is unknown and there are no established methods to distinguish the two using the 3\u2009\u00b5m band4. However, a fundamental vibration of molecular water produces a spectral signature at 6\u2009\u00b5m that is not shared by other hydroxyl compounds5. Here, we present observations of the Moon at 6\u2009\u00b5m using the NASA\/DLR Stratospheric Observatory for Infrared Astronomy (SOFIA). Observations reveal a 6\u2009\u00b5m emission feature at high lunar latitudes due to the presence of molecular water on the lunar surface. On the basis of the strength of the 6\u2009\u00b5m band, we estimate abundances of about 100 to 400\u2009\u00b5g\u2009g\u22121 H2O. We find that the distribution of water over the small latitude range is a result of local geology and is probably not a global phenomenon. Lastly, we suggest that a majority of the water we detect must be stored within glasses or in voids between grains sheltered from the harsh lunar environment, allowing the water to remain on the lunar surface.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>C.
