The moon’s oldest and darkest craters could be hiding the most water ice. That’s good news for future astronauts

AI-summarised brief · reviewed before publication

Scientists have discovered that water ice on the moon's surface may have accumulated gradually over billions of years, rather than in a single event. Research suggests that permanently shadowed craters at the lunar south pole, previously thought to be consistently cold, have experienced changes in illumination due to the moon's tilt. This finding is significant for future lunar missions, where water ice could provide a vital resource for astronauts.
