What this work contributes
NASA distinguishes basic principles, formulated concepts, analytical and experimental proof of concept, laboratory validation, and progressively more relevant environment demonstrations. These definitions support publishing separate maturity labels for a mathematical hypothesis, a force-measurement fixture, a component, and a complete propulsion system.
Where the evidence stops
The framework supplies criteria, not an independent readiness assessment of this company; a website, animation, simulation, or roadmap does not itself establish TRL 3 or higher.
