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
- Crewed pressure modules, expandable structures, MMOD shields, and human-factors standards are operational in Earth orbit.
- Rotating-habitat gravity follows well-understood physics, but lifetime comfort and developmental biology have not been validated.
- Spaceflight standards focus on small groups of healthy professional adults rather than a diverse civil population.
Major unknowns
- Safe gravity level, rotation rate, gradient, and exposure for pregnancy, childhood, aging, and disability are unknown.
- Large crew-bearing rotating pressure interfaces integrated with habitation utilities, changing mass distributions, civil evacuation, and locally sustained century-scale maintenance remain unvalidated.
- Passive GCR shielding is mass-intensive; active shielding is experimental and adds new failure hazards.
Failure modes
- Fatigue, creep, seal aging, debris impact, or undetected corrosion propagates through a pressure boundary.
- Rotation hardware or mass imbalance creates vibration, bearing, control, and evacuation hazards.
Useful precursors
- Long-duration pressure-vessel and material-exposure programs on stations, the Moon, and uncrewed orbital platforms.
- Human-rated rotating-habitat demonstrations that validate balance, access, repair, and safe spin transitions.
Decision gate
Require full-scale human-in-the-loop mockups, diverse-body accessibility review, fire/refuge tests, and long-duration rotating-environment evidence.
Claim records
- A worldship would combine a pressure vessel, rotating machine, city, hospital, school, farm, factory, and refuge; this bounded standards survey did not identify one standard covering that combination.
