An electrodynamic assembly for propelling a spacecraft in orbit around a celestial body having a magnetic field is disclosed. The assembly includes a plurality of coaxial cables for an electrodynamic assembly for propelling a spacecraft in orbit around a celestial body having a magnetic field. Each coaxial cable includes an electrically conductive core surrounded by a first electrically insulating sheath, and an electrically conductive current return circuit mounted outside the first electrically insulating sheath. The current return circuit includes a first end electrically connected to a first end of the core of the coaxial cable.

A Hall effect plasma thruster including an annular discharge channel around a main axis presenting an open downstream end and defined between an inner wall and an outer wall, at least one cathode, a magnetic circuit for creating a magnetic field in the channel, a pipe for feeding ionizable gas to the channel, an anode, and a manifold placed in the upstream end of the channel. The manifold is connected to the pipe and enables the ionizable gas to flow into the ionization zone of the channel in concentric manner around the main axis. The anode acts as a manifold, and the manifold includes a directional mechanism that gives rise at an outlet from the manifold to swirling motion of the gas around the main axis.
