ArianeGroup's GRETA completes hot‑fire campaign as ESA funds next‑stage development of peroxide–ethanol engine

ArianeGroup’s GRETA small rocket engine finished a comprehensive hot‑fire test campaign in Trauen, demonstrating stable operation, controlled shutdowns and multiple restarts in the ~5 kN thrust class. ESA has awarded a follow‑on contract to advance GRETA — a hydrogen‑peroxide/ethanol architecture aimed at landers and Ariane 6 upper/kick stages.
