Theoretical concept for a novel multi-layer active shielding architecture designed to attenuate high-energy galactic cosmic rays (GCR) — the primary unresolved radiation hazard for long-duration human spaceflight, immune to practical magnetic deflection above 1 GeV/nucleon. The MLVIS exploits three coupled physical mechanisms: (1) a helical nanopolymer pre-conditioner converts the rectilinear GCR trajectory into a helical path, maximizing coupling to magnetic vortex structures without external magnetic field; (2) alternating magnetic domains (+B/−B) in type-II superconductors (REBCO) induce opposed Abrikosov vortex fronts that collide and dissipate particle energy through destructive interference — a mechanism not previously proposed for radiation shielding; (3) multiple independent shield layers are deployed at distance from the primary habitat (Refuge Sphere, DOI: 10.5281/zenodo.19822922) with free space between layers, so that MLVIS-impoverished particles reaching the Refuge Sphere are already deviated and energy-reduced, making the Meissner shielding partially effective against particles previously undeflectable. For planetary surface bases (Refuge Sphere Lunar Village, DOI: 10.5281/zenodo.19920193), fixed MLVIS shields cover exposed zones while retractable shields respond to SPE/GCR alerts. Physical basis: Abrikosov vortex dynamics (Nobel Prize 2003), closed toroidal vortex excitation by charged particle beams (Kozlov & Samokhvalov, Russian Academy of Sciences), velocity-dependent vortex interaction (Kogan & Prozorov, 2020), crystal channeling (Lindhard, 1965). A full theoretical paper with quantitative attenuation estimates is in preparation.
