Decision

What the current evidence supports

Agent-assisted assessment · independently reviewed · 2026-10-21

Use Chang’e-6 results for research scoped to its sampled region.

Why
The completed return continues to produce substantive scientific results, while repeated far-side return reliability remains unestablished.
Next
Check sample-allocation eligibility and apply published measurements with their sampling and analytical limitations.

Constraints

Blockers

  • Physical samples require allocation through the sample-management process.
  • One sampling region limits geological generalization.
  • Repeatability of the complete far-side return architecture remains unestablished.
