A spacecraft is equipped with a low and high thrust space propulsion system including at least one water reservoir (1) containing liquid water, a high thrust propulsion part and a low thrust propulsion part. The high thrust propulsion part has a high thruster including a regulation valve (V1) for drawing water from the liquid water reservoir (1), a device for splitting (2) liquid water into gaseous hydrogen and gaseous oxygen, relative storage tanks (3, 4), a combustion chamber (5) in which the gaseous hydrogen reacts with the gaseous oxygen and an exhaust nozzle (6) from the combustion chamber (5). The low thrust propulsion part comprises a liquid water supply line (10) and a plurality of liquid water outlets in a plurality of branches (11-1n) individually including a regulating valve (21-2n), a vaporization chamber (31-3n) and an expansion nozzle (41-4n).
