What this node means
Earth launch cost is the first line item: mission mass multiplied by a launch-price assumption or replaced by a fixed launcher baseline.[1,2,3]
Why it matters
In the CosmosExplore model, earth launch cost is kept as a separate node so cost, logistics, and risk assumptions stay inspectable.[1,2,3]
Guardrails
- This entry is a model context node, not a mission quote, route promise, or safety assessment.[4]
