A thermodynamic and physicochemical framework for lunar ice mining by induced sublimation
Meaning A thermodynamic and physicochemical framework for lunar ice mining by induced sublimation refers to a scientific model that explains how heat energy can be applied to lunar subsurface ice deposits to convert solid ice directly into vapor, which can then be captured and condensed into usable water. It integrates thermodynamics (energy transfer and heat balance) with physicochemical principles (phase change, material behavior, and chemical composition) to optimize water extraction in the Moon’s harsh environment. Introduction Water ice found in permanently shadowed regions (PSRs) of the Moon is crucial for future lunar habitation and resource utilization. Extracting this ice through induced sublimation—using controlled heat sources such as microwaves, lasers, or focused solar energy—presents a promising in-situ resource utilization (ISRU) strategy. Developing a thermodynamic and physicochemical framework allows scientists and engineers to predict ice behavior under vacuu...
