Statement
No crew launch without high-confidence robotic characterization and a presumption against settlement where credible indigenous life is detected.
Evidence dimensions
- Basis
- normative
- Readiness
- early research
- Confidence
- supported
Assessment rationale
Current treaty and planetary-protection policy require due regard and contamination controls, while habitable-zone membership does not establish habitability or absence of life. The no-crew-launch rule is a precautionary GShips threshold, not existing interstellar law.

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 authoritative, independently reviewed scientific and ethical protocol showing that another characterization sequence protects indigenous life at least as well could replace the robotic-first threshold.
