Cosmological and Thermodynamic Inviolability of the Lunar Surface: Unifying the "Tsukuyomi" Principle of Non-Self-Luminous Celestial Symmetry with Physical Limits on Nuclear and Fusion Deployment in the Artemis Era

The contemporary acceleration of the Artemis program and competitive lunar base architectures pursued by international space agencies and commercial defense conglomerates presumes the deployment of megawatt-scale artificial thermal engines—preeminently fission reactors (e.g., Kilopower, high-temperature gas-cooled reactors) and proposed fusion installations—as a necessary engineering prerequisite for permanent human colonization and industrial regolith extraction. This monograph rejects this industrial-military imperative by establishing a rigorous synthesis between non-equilibrium astrophysical thermodynamics, space law, and comparative cosmological philosophy. Scientifically, the Moon is an intrinsically passive, non-self-luminous celestial body governed by an optical albedo of A ≈ 0.12, maintaining a delicate, billions-year-old radiative equilibrium with ambient solar flux and the cryogenic cosmic microwave background (2.73 K). In Japanese classical cosmology, this physical reality is codified through the archetype of Tsukuyomi-no-Mikoto—the deity of lunar cycles and tidal symmetry who, unlike the active, self-luminous solar sovereign Amaterasu-Omikami, embodies receptive equilibrium, non-interference, and reflective serenity. Through rigorous heat-transport modeling, we prove that deploying megawatt-scale artificial heat engines in the ultra-vacuum environment of the lunar surface precipitates catastrophic localized entropy inversion: (1) constrained by the Stefan-Boltzmann radiative limit (P_rad ∝ T^4), massive heat rejection arrays induce uncontained conductive thermal leakage across the insulating regolith (k_regolith ≈ 10^-3 W/(m·K)); (2) Clausius-Clapeyron sublimation kinetics accelerate water-ice loss in 40 K Permanently Shadowed Regions (PSRs, such as Shackleton and Cabeus craters) by over eight orders of magnitude under a modest 5 K thermal leakage footprint, irreversibly destroying irreplaceable volatile reserves; and (3) this localized thermal pollution constitutes "harmful contamination" under Article IX of the 1967 Outer Space Treaty. We formulate the Tsukuyomi Protocol—a binding legal-engineering covenant declaring the Moon an immutable, non-nuclear celestial sanctuary, prohibiting high-temperature nuclear reactors and preserving cosmological balance against extractive industrialization.
