3rd June, 2022 – The first Italian private launch vehicle rocket engine ever tested.
Sidereus has successfully tested the MR-200, the first bipropellant kerosene-liquid oxygen rocket engine, the beating heart of EOS single-stage to-orbit launch vehicle. This ablative-cooled 2.5 kN engine performed successfully at 87% efficiency for over 10 seconds.
