PROPULSION TEST FAQ
ENGINE TESTING & LAUNCH FAQ
How many hot-fire firings are required to qualify a flight engine?
To achieve flight qualification clearance (75%+ rating), players must conduct approximately 13 to 19 one-minute hot-fire test firings on Level 2 engine test stands ($650K).
What are the costs and steps for the inaugural rocket launch?
The inaugural rocket costs $2.8M to manufacture across 8 assembly stages, followed by 180s transport, 180s erection, a $350K static fire test (240s), and a 30s launch countdown sequence.
