Meanwhile, the discovery suggests a possible water source for lunar
explorers. By processing the hydroxyl-rich minerals, future astronauts
could, indeed, find a way to squeeze water out of a stone.

The Moon might be a bit of a dark horse when it comes to water.

According to a new analysis of mineralogy maps, water and hydroxyl –
another molecule made up of hydrogen and oxygen – can be found in
multiple locations across all lunar latitudes and terrains, even where
the Sun shines down most powerfully.

It's a discovery that has multiple implications. It can help us
understand the Moon's geological history and ongoing processes, and
inform future crewed missions to Earth's satellite.

"Future astronauts may be able to fin
