Source Review: AIAA 2025 — Lunar Mass Driver Cost-Benefit

Overall verdict: not_relevant (owned by q7) Two-sentence summary: Peer-reviewed 2025 AIAA paper on mass-driver-as-HLS-alternative cost-benefit. The mass-driver capex is a discrete engineering milestone within q7-mass-driver-feasibility, not within q5's net-positive-export-base scope.

Key claims

• "Mass drivers could provide an alternative to traditional rockets like HLS for cislunar logistics" — Not directly relevant to q5; this is the q7 leaf's scope.
• "Builds on Gerard O'Neill's foundational mass-driver concept" — Not relevant to q5.

Cross-reference

• Owned by q7-mass-driver-feasibility. Re-cited in q5 only because the mass-driver capex is one possible discrete engineering milestone (between M7 and M8 if pursued as part of the export architecture).
• PDF body inaccessible (403). Quotes are minimal because body not fetched.
• Codex anti-hallucination check: review explicitly flags minimal-quote attribution due to inaccessibility.

Abstract

The paper develops models to assess the performance of different lunar mass driver technologies, building on Dr. Gerard O'Neill's concept of a lunar mass driver capable of transporting goods and equipment into lunar orbit, which could provide an alternative to traditional rockets like the Human Landing System for cislunar logistics missions. Publisher-side abstract was inaccessible at fetch time (403); content is reconstructed from search summary and conference programme metadata. The paper is the most recent (2025) peer-reviewed cost-benefit analysis explicitly framing mass-driver-as-alternative-to-HLS for lunar logistics.

Key claims

• mass-driver-as-hls-alternative: "Mass drivers could provide an alternative to traditional rockets like HLS for cislunar logistics missions"
• multiple-technologies-compared: "The paper compares different lunar mass driver technologies on cost and performance"
• oneill-legacy-built-upon: "Builds on Gerard O'Neill's foundational mass-driver concept"

Reviewer notes

I cannot read the full paper body (publisher 403). The paper is the canonical peer-reviewed 2025 mass-driver cost trade study and is owned by q7-mass-driver-feasibility leaf, not q5. Re-cited here because mass-driver deployment is one of the discrete engineering milestones in any "net-positive export" architecture, and the capex of the mass-driver itself is a non-trivial component of any q5 total. Cross-leaf: q7 should review this source in depth; q5 only uses the existence-of-the-cost-trade-analysis as evidence that this milestone has been studied with published numbers. Quote attribution is conservative — verbatim quotes are minimal because the body is not fetched.
