The Moon has more water than previously thought, and it’s deep below the lunar surface. A new study suggests that water is widespread beyond the poles, where it was already known to exist, although scientists don’t know exactly how much water is there. The discovery has consequences for future missions to the Moon.

Scientists analyzed lunar rock samples that contain tiny, water-trapping beads of glass; these beads formed when magma erupted from the Moon’s interior billions of years ago, trapping water inside them. The scientists then looked at satellite data collected by an Indian lunar orbiter to check where these water-trapping glass beads are. The results, published today in Nature Geoscience, show that there are widespread “hot...
