Space Habitats & Life Support · Projected milestone
Lunar life-support spare-part independence
20% by 2100 · including earlier years
The year is an editorial timing estimate. The percentage applies to occurrence by the stated deadline. These estimates are not calibrated odds.
One lunar habitat meets all routine life-support replacement demand for five years from locally processed lunar feedstocks, including sensors, membranes, seals and catalysts, with audited inventories excluding imported replacement assemblies or raw precursors.

Milestone stage: integrated capability demonstration
full manufacturing closure not demonstrated
Timing window: 2075–2100. An editorial range, not a statistical confidence interval.
Completion criteria: One lunar habitat meets all routine life-support replacement demand for five years from locally processed lunar feedstocks, including sensors, membranes, seals and catalysts, with audited inventories excluding imported replacement assemblies or raw precursors. Resolve only from inspectable evidence meeting every stated criterion; a plan or extrapolation does not resolve it.

Sources & evidence
- NASA seeks industry input to accelerate lunar surface technologies 2026
The 2026 program connects lunar resources, power and manufacturing to reduced reliance on Earth; it does not promise a closed industrial supply chain.
- NASA 2026 Civil Space Shortfalls 2026-03
Identifies gaps in extraction, processing, storage and use of locally produced lunar materials. It provides an evidence basis for missing dependencies, not a date for independence.
