This invention relates to a mass-optimized geogrid system and method for stabilizing regolith and other granular soils in extraterrestrial and extreme Earth environments. Mass reduction is achieved both locally—within individual geogrid layers through optimization of lattice geometry, variable mesh density, and reinforcement at stress concentrations—and globally, by varying the spacing and distribution of layers according to structural demands. The geogrid may be fabricated from materials that are locally sourced or compositionally traceable to in-situ resource utilization (ISRU) processes in environments such as the Moon, Mars, or terrestrial polar and desert regions where conventional construction materials are limited or costly to transport. The method includes restructuring the regolith by size-sorting and compaction to produce a particle-size distribution proportionally matched to the mesh openings, enhancing mechanical interlock and shear resistance. Structural efficiency can be tuned and verified through physical testing and finite-element analysis for scalable, repeatable construction.
