On October 26, Nature Astronomy published an article saying that NASA, relying on the Stratospheric Infrared Observatory "Sophia", detected water molecules for the first time on the surface of Cravis Crater in the southern hemisphere of the moon, the lunar light zone.
This discovery indicates that water may be distributed on the whole moon surface, not only on the dark back of the moon. In other words, water can exist on the surface of the moon even under solar radiation. [3]
