Statement
A stellar mission must navigate, preserve truth, and communicate through growing delay and eventual practical independence from Earth.
Evidence dimensions
- Basis
- modeled
- Readiness
- breakthrough dependent
- Confidence
- supported
Assessment rationale
Finite light speed and stellar distance create unavoidable communication delay, while current deep-space networks, disrupted-network protocols, navigation archives, and preservation standards depend on bounded infrastructure and institutional support. A centuries-long mission therefore needs local navigation, verifiable records, and decision capacity even if communication with Earth continues.

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?
A mission architecture with independently verified navigation, communication, archival interpretation, local authority, and safe operation through representative multi-decade isolation would raise readiness. New physics enabling materially faster verified communication would change the delay premise; continued dependence on unavailable Earth expertise, keys, clocks, or ephemerides would lower it.
