Revolutionizing Space Travel: Prometheus and the Era of Reusable Rockets

ArianeGroup has successfully tested Prometheus, a 100-tonne thrust class engine designed for cost-effective, clean, and reusable space travel. Using liquid oxygen-liquid methane fuel and 3D printing, Prometheus aims to reduce costs and simplify handling. Mounted on a prototype reusable rocket stage called Themis, further tests will evaluate flight and landing capabilities. Prometheus and Themis are expected to be key components in future European launchers.
