Evidence dimensions
- Basis
- demonstrated
- Readiness
- major scale up
- Confidence
- supported
Assessment rationale
NASA risk, design, and standards material supports privacy, sleep, controllable environmental conditions, recreation, personalization, and social considerations in current crewed contexts. The claim does not establish universal preferences or a civil habitat's quantitative requirements.

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?
Diverse-population research showing that different spatial, sensory, temporal, and social-control variables better predict sleep, health, privacy, conflict, belonging, and recovery would revise the listed design priorities.
