Chinese researchers may have discovered billions of tons of water inside strange glass spheres buried on the moon, and they could be used as a future water source for moon bases, a new study suggests.
The tiny glass spherules, collected in lunar soil samples and brought to Earth by China's Chang'e-5 mission in December 2020, could be so abundant that they store up to 330 billion tons (300 billion metric tons) of water across the moon's surface, the new analysis, published March 28 in the journal Nature Geoscience, shows.
