Systems and methods for autonomous extraction of volatile minerals from extraterrestrial regolith are disclosed. A rover tows a mineral-collection wagon that mechanically prepares surface regolith and positions a detachable collector shield over a target area. When lowered, the shield rim seals against the regolith to define a localized, low-leakage environment. A radiant heating element raises the regolith to vaporization temperature; released species migrate to the shield's inner surface, which is cryogenically or ambiently cooled to condense solids as a removable film. After a heating / collection cycle, the shield is decoupled for retrieval and processing while the wagon immediately accepts a replacement shield, enabling continuous, modular operation. Embodiments support guided alignment, power coupling, optional daisy-chained wagons, and reciprocating or continuous motion to increase throughput on lunar or similar vacuum surfaces.
