Researchers found water molecules in the moon


IllustrationIllustration -  The moon seems to have never dried up in total, it’s different from the predictions of scientists long ago. Reporting from BGR, the conclusion was obtained by scientists from NASA's Lunar Reconnaissance Orbiter (LRO) data to detect water molecules and water vapor for one day on the moon.

Before the data is available, the Moon is always considered a dry and dusty place. But over time, the picture has changed. Scientists found ice near its poles, and it was recently discovered that water did exist in the surface material of the moon, called regolith.

Now, LRO has revealed that the water on the surface of the Moon moves during the day time of the month. A study of the Moon's humidity which will be published in Geophysical Research Letters provides a clear picture of living water molecules on the surface.

"Water molecules remain tightly bound to regolith until surface temperatures peak near the daylight. Then, molecules are thermally absorbed and can bounce to nearby locations that are cold enough for molecules to stick or fill the atmosphere exosphere that is very weak on the moon and the molecule returns to the surface"

Mapping Project Lyman Alpha uses readings from LRO to detect the presence of water in regolith, which allows researchers to track the movement of moisture. Data like this that can be very useful when planning future missions and even potentially permanent settlements on the Moon.
