Scientists at the University of Maryland and Lawrence Berkeley National Laboratory used seismic waves to detect ice buried beneath the lunar surface. Their study, published in Science Advances, could help NASA's Artemis program find water ice for future missions. The team found that seismic waves travel faster through frozen soil than dry soil, making it possible to locate underground ice.
Scientists at the University of Maryland and Lawrence Berkeley National Laboratory have discovered a new way to detect hidden ice on the Moon using moonquakes. Their study, published in Science Advances on July 31, 2026, could help NASA's Artemis program find water ice for future missions.
The team used seismic waves, which are similar to the vibrations measured during earthquakes, to locate underground ice. They found that frozen soil and dry soil behave very differently when a seismic wave passes through them. Ice stiffens whatever it's mixed into, making vibrations travel two to three times faster than they would through dry dirt.
The team tested their theories by freezing a volcanic rock from Arizona that mimics moon dust, using X-rays to study how ice settles into tiny gaps between soil grains, and running computer simulations of small moonquakes. In every case, the ice left clear and measurable marks on the seismic data.
This discovery is crucial for future missions because water ice can be melted and purified to become drinking water. It can also be split apart with electricity to yield oxygen to breathe and hydrogen for rocket fuel. Locating a steady supply of lunar ice could dramatically reduce what future missions need to haul from Earth.
