Statement
A ship must cultivate calories, nutrients, microbial function, ecological resilience, and cultural meaning—not merely grow salad.
Evidence dimensions
- Basis
- normative
- Readiness
- major scale up
- Confidence
- supported
Assessment rationale
Space crop experiments establish bounded plant production, while nutrition, food-system, microbial, labor, cultural, and resilience sources show that edible leaves are only one function of a complete food system.

Assumptions and limits
The assessment applies to this bounded statement and the cited source scopes. A source can support one relationship without validating a generation ship, and an editorial grade does not substitute for independent review or representative demonstration.
What would change this conclusion?
An independently verified system that safely nourishes a representative changing population with resilient production, reserves, acceptable labor, cultural agency, and full resource accounting would narrow this requirement.
