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
- Daedalus and Longshot are uncrewed interstellar probe studies; HERITAGE is a demographic simulation; Project Hyperion is a 2025 generation-ship design competition. Each exposes a different bounded trade, and none is a validated integrated mission.
- NASA systems-engineering practice supplies mature methods for requirements, interfaces, verification, risk, and lifecycle decisions.
- No accepted reference architecture joins technical, biological, institutional, legal, and intergenerational requirements for a crewed stellar mission.
Major unknowns
- The destination, cruise speed, population, industrial closure, mission duration, and arrival strategy remain architecture-driving unknowns.
- There is no validated way to assign requirements to people who will be born generations after departure.
- Economic feasibility depends on a mature Solar System industrial base that does not yet exist.
Failure modes
- Requirements growth hides mass, energy, braking, logistics, and contingency costs until the design is no longer coherent.
- A favored reference mission crowds out safer probes, Solar System habitats, waiting, or a valid do-not-launch decision.
Useful precursors
- Auditable requirements and digital-twin exercises for remote habitats, disaster logistics, and long-duration Solar System missions.
- Robotic interstellar precursor studies that close acceleration, cruise, communications, arrival, and braking budgets.
Decision gate
Do not approve an irreversible mission architecture until alternatives, arrival, braking, rights, rescue limits, and whole-lifecycle maintenance have independent evidence.
Claim records
- A generation ship is a civilization-scale system of systems; propulsion cannot be evaluated independently from population, maintenance, ecology, governance, arrival, and the possibility of not going.
