What this node means
Crew-system fixed cost captures vehicle, service module, ground system, and other human-flight assumptions that do not shrink with passenger count in a simple way.[1,2]
Why it matters
In the CosmosExplore model, crew-system fixed cost is kept as a separate node so cost, logistics, and risk assumptions stay inspectable.[1,2]
Guardrails
- This entry is a model context node, not a mission quote, route promise, or safety assessment.[3]
