Successfully living and working on the Moon requires efficiently extracting resources like ice, especially in extremely cold, permanently shadowed regions near the lunar poles. Current models used to understand how ice and water vapor move through lunar soil rely on assumptions about the lunar surface. To improve these models, detailed imaging experiments were performed using X-ray tomography to see how simulated lunar soils mixed with ice grains change under conditions similar to the Moon. The experiments showed clear evidence of ice moving and with particles becoming compacted as ice shifted. By analyzing these scans, it is possible to directly measure properties controlling how gases flow through lunar soils. These new measurements will significantly improve computer models used to predict ice behavior, helping to guide future lunar exploration and resource extraction missions.
