Griffiths Hydrogen-Rich Subcutaneous Radiation-Shielding Membrane Architecture

The Griffiths Hydrogen‑Rich Subcutaneous Radiation‑Shielding Membrane Architecture introduces a multifunctional protective system for long‑duration interstellar habitats. This architecture integrates a hydrogen‑rich, self‑sealing fluid membrane between the inner pressure shell and outer structural shell of a spacecraft, providing radiation attenuation, micrometeoroid protection, thermal buffering, and dual‑use mass storage for life‑support and propulsion systems. The membrane leverages water, hydrogels, stabilized wet waste, and localized methane reservoirs to create a continuous toroidal shielding layer with 10–20 g/cm² areal density. Sectorized pumping and isolation valves enable dynamic mass redistribution, storm‑shelter reinforcement, and damage containment. The system enhances rotational stability in artificial‑gravity habitats and couples directly with propulsion architectures, allowing membrane fluids to serve as thermal working mass, electrolysis feedstock, or emergency reaction mass. This whitepaper defines the membrane’s structural integration, self‑sealing behavior, radiation‑attenuation performance, manufacturing pathways, failure‑mode logic, and mission‑level operational doctrine. It expands the Griffiths canon by unifying shielding, structure, life‑support, and propulsion into a single mass‑efficient subsystem optimized for multi‑decade interstellar missions.
