ArianeGroup has successfully conducted a series of hot-fire tests on a 3D-printed, flight-configured 240N hydrogen peroxide thruster at the DLR facilities in Lampoldshausen, Germany. Led by ArianeGroup, the SALTO project, funded in part by the European Commission, aims to advance technologies for reusable launch vehicles, with a focus on vertical landing capabilities. The thruster's development is speculated to be associated with the Themis project, a European Space Agency initiative for testing and validating key technologies. ArianeGroup is preparing the Themis vehicle in Les Mureaux, France, with final verification of flight-configured components and integration of the hydrogen peroxide thruster for precise attitude control during flight phases. The upcoming Themis demonstrator is expected to utilize the Prometheus rocket engine as its primary propulsion system and a flip control thruster developed by SpaceForest for initiating rotation before re-entry burn. The successful completion of the hydrogen peroxide thruster test marks a milestone in enhancing space technology for future missions.
