Past observations suggest that there is water on the moon. New telescope observations conclude that those findings hold water.
The spacecraft has found evidence of water ice in permanently shaded pits at the lunar poles (SN: 5/9/16) and traces of water molecules on the surface of sunlight (SN: 9/23/09). But water visions in sunlight areas rely on the detection of infrared light at a wavelength that can be emitted by other hydroxyl compounds that contain hydrogen and oxygen.
Now, the Stratospheric Observatory for Infrared Astronomy, or Sophia, has detected a unique infrared signal to the water near the lunar south pole, researchers report online on October 26 in Nature Astronomy. "This is the first time that molecular water has been detected in sunlight on the moon," said Casey Honniball, a lunar scientist at NASA's Goddard Space Flight Center in MD's Green Belt. “It shows that water is not just permanently shaded - there are other places on the moon where we can find it. "
These observations may indicate future travel to the moon, which will emit lunar water as a potential resource for human observers.
