The term “in situ resource utilization” (ISRU) refers to the consumption of lunar resources such as icy regolith for the production of consumables for autonomous or human operations on the Moon. ISRU methods for future lunar exploration are now focused mostly on the production of oxygen and water for human use. Permanently Shadowed Region near the lunar poles has craters that might be mined for ISRU because to their high concentrations of water and other volatiles.
