Water has been found conclusively for the first time inside ancient moon samples brought back by Apollo astronauts. The discovery may force scientists to rethink the lunar past and future, although uncertainty remains about how much water exists and whether future explorers could extract it.
The water was found inside volcanic glass beads, which represent solidified magma from the early moon’s interior. The news swept through much of the scientific community even before being detailed in the journal Nature this week.
