What this node means
Reusable boosters do not automatically remove expendable upper-stage or mission-integration costs.[1,2]
Why it matters
In the CosmosExplore model, upper-stage expendables 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]
