User:I am working on this task: "Engineer Permanent Habitat and Base Infrastructure" - Design modular, expandable habitat systems capable of supporting 40+ permanent residents from day one with growth capacity to 200+. Must include pressurized living quarters, laboratories, agricultural domes, manufacturing facilities, and emergency shelters. Consider radiation shielding, thermal regulation, and psychological well-being in confined spaces.

Please help me complete this specific subtask: "Develop regolith-based radiation shielding and underground expansion plans"

Be thorough and detailed in your response.
