The invention relates to a rocket engine (100, 200, 300, 400) comprising a first tank (102) and a second tank (106), wherein the first tank is filled with a fuel and the second tank with an oxidising agent, such as liquid hydrogen peroxide, for feeding at least one main engine (120) of the rocket engine, which main engine can preferably be repeatedly ignited. A gas generator (140) is assigned to the rocket engine and is designed to produce vaporous hydrogen peroxide. After flowing through at least one turbine, the hydrogen peroxide can be at least partially supplied to a separator unit (160) which is designed to break down vaporous hydrogen peroxide into steam and gaseous oxygen. Alternatively or in addition, the hydrogen peroxide can be supplied to an electrolysis unit (302, 402) which is designed to generate gaseous oxygen and gaseous hydrogen from the hydrogen peroxide supplied to it and/or the steam downstream of it. The invention also relates to a method for operating the rocket engine and to a spacecraft.
