Source Review: Research and Markets — On-Orbit Propellant Depot Market 2026
Verdict: Consistent Confidence: low-medium
Industry-research summary. The ~$4,000/kg propellant-at-depot estimate matches q2-lunar-ascent-cost's reconciled figure of $4,162/kg derivation. Multi-billion 2030 market sizing aligns with q6.c5 BAU depot demand scale. Low-confidence as a stand-alone source; valued as trade-press corroboration of academic figures.
