Vault Compartmentalization

Internal Compartment Walls for Differential Protection

Vault compartmentalization uses 5,000 kilograms of tungsten internal walls, borated polyethylene liners, and 316L stainless steel doors to establish five independently sealed differential protection zones within the Lunar Ark vault. Operating on a celestial body without a protective magnetosphere, the system applies a defense-in-depth architecture to isolate irreplaceable biological assets, including human DNA and embryos, from deep-space radiation. The layered layout progressively reduces radiation exposure to 0.1 millisieverts per year at the innermost core, enabling phased degradation if outer shielding fails. Drawing zero power across a 100-year service life, each compartment relies on long-life metal-and-glass seals configured exclusively for robotic access.

Internal compartment walls within vault providing additional shielding for the highest-priority samples and creating differential protection zones.
