Prometheus prototype engine test

Scenes from a 30-second burn with re-ignition of an early prototype of the Prometheus engine at ArianeGroup’s test facility in Vernon, France, on 20 October 2023.
The 100-tonne thrust class Prometheus burns liquid oxygen-liquid methane fuel. Methane is clean burning and simplifies handling, to help enable reusability and reduce the cost of ground operations before and after flight.
