Statement
Economic feasibility depends on a mature Solar System industrial base that does not yet exist.
Evidence dimensions
- Basis
- proposed
- Readiness
- breakthrough dependent
- Confidence
- tentative
Assessment rationale
Current official assessments describe in-space servicing, manufacturing, and resource-use capabilities as incomplete programs with major technical, policy, supply-chain, and economic gaps. A mature Solar System industrial base is a plausible dependency for affordability, but no cited source establishes a unique economic threshold or proves that no alternative financing and architecture could work.

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 reviewed costed architecture showing credible construction, replenishment, launch, energy, labor, insurance, and lifecycle financing without a mature off-Earth industrial base—or operational evidence that such a base now exists—would materially change the conclusion.
