Abstract: An ion thruster, comprising: a discharge chamber for accelerating ions towards one direction; an inflow opening for intake of a propellant into the discharge chamber; a discharge cathode, shaped in a form of a propeller, for releasing electrons in the discharge chamber, thereby ionizing the propellant in the discharge chamber, wherein the discharge cathode is rotatable around an axis, thereby propelling inward to the discharge chamber the propellant thereof; an outflow opening for exhausting the ions from the discharge chamber; and an accelerator electrode, shaped in a form of a propeller, for accelerating the ions towards the one direction of the outflow opening, wherein the accelerator electrode is rotatable around an axis, thereby propelling outward from the discharge chamber the ions and neutral atoms thereof; wherein the ion thruster comprises electromagnetic coils for generating a magnetic field inside the discharge chamber.
