Editorial boundary: This public alpha is generated from version-controlled source without third-party application or build packages. It is not the reviewed 1.0 corpus: 60 Academy lessons are substantive editorial drafts, 0 remain foundation outlines, and independent domain review remains open.
Current state
- Crop chambers, microbial biomanufacturing experiments, controlled agriculture, and closed-ecology analogs provide distinct evidence at different scales, durations, environments, and achieved functions; they should not be treated as one demonstration class.
- ESA MELiSSA develops regenerative life-support compartments and progressive integration; it has not demonstrated a completed multigenerational closed ecology.
- Biosphere 2 and Lunar Palace report different, boundary-specific closure results and also expose chemical, material, operational, and microbial couplings.
Major unknowns
- A complete, nutritionally adequate, culturally acceptable diet has not been regenerated in space.
- Crop disease, pollinator loss, loss of required microbial function, pathogen increase, reduced diversity, instability, salt accumulation, and harmful genetic change can propagate across tightly coupled loops.
- Small chambers do not scale linearly to neighborhoods with children, animals, varied diets, and changing population.
Failure modes
- Crop disease, pollinator loss, nutrient imbalance, or genetic uniformity produces correlated food failure.
- The ecology meets calories but loses micronutrients, soil function, resilience, or acceptable food culture.
Useful precursors
- Controlled-environment agriculture, regenerative nutrient recovery, seed-bank, and distributed food-resilience programs.
- MELiSSA-class and other multi-trophic closed-ecology testbeds operated through several crop and microbial cycles.
Decision gate
Operate an integrated hybrid ecology through multi-season failures while measuring every essential element and publishing negative results.
