> ArianeGroup announced last week that it had completed a test campaign of a Prometheus engine prototype that included a 30-second hot fire test.
> Prometheus began as a CNES project in 2015, with the agency projecting that a full-scale demonstrator of the engine would be ready for a hot fire test in 2020. The engine was intended to be a low-cost reusable methalox rocket engine that would produce 1,000 kN of thrust and power the next generation of European launch vehicles. The aim was to get to a point where Prometheus engines could be produced for no more than €1 million per unit.
> According to ESA, Prometheus testing will “accelerate” with the delivery of two new Prometheus prototypes. One of the two prototypes will be installed onto a test bed at the DLR test facility in Lampoldshausen, Germany. Testing of this prototype will begin next year.
> Although a Prometheus engine is expected to fly aboard a Themis demonstrator next year, an initial orbital flight of the engine will not occur until late 2025 at the earliest aboard a Maiaspace microlauncher.
