The Orbital Mega-Structure Fabrication Mandate & In-Situ Resource Utility

Beginning in the mid-2030s, advanced propulsion technologies and the rapid decline of launch costs fundamentally altered the economic calculus of space exploitation. The prevailing model shifted from simple resource extraction—the retrieval of valuable bulk minerals—to utilizing orbital mechanics and microgravity environments as primary manufacturing platforms. This mandate, characterized by the continuous deployment and self-assembly of massive off-world structures (mega-structures), represents a foundational industrial shift: industry is increasingly decoupled from terrestrial physical constraints. Mega-structures range from kilometer-scale solar power collectors to vast computational substrates and orbital habitat arrays, all requiring specialized material processing performed *in situ* using asteroidal or lunar resources.
