Abstract: A system and method for transferring a satellite from an initial orbit into a mission orbit. The method includes anchoring to the satellite of an external unit having a tank containing a reserve of propellants. The system includes an autonomous spacecraft having an electric propulsion module and a small internal reserve of propellants, located in a parking orbit close to the initial orbit. The spacecraft with the external unit attached to the satellite is docketed in an initial orbit, to produce a fluidic connection of the propellant tank of the external unit to the propulsion module of the spacecraft. The external unit and satellite is transferred into the mission orbit by the electric propulsion module of the spacecraft supplied with propellants directly from the external unit, thereby releasing the satellite into the mission orbit.

Abstract: A projectile intended for damping a spacecraft (100) comprising a main body (110) and active attitude control means (150) comprises a harpoon and is intended to equip a space delivery vehicle to be projected towards the spacecraft. It comprises a passive damper (200) mounted such that it is fixed on the harpoon and suitable for generating, in cooperation with the Earth's magnetic field, a damping torque. That passive damper (200) comprises an outer enclosure (210) and an inner body (220) configured such that: the inner body, permanently magnetized, is positioned inside the outer enclosure and is capable of moving in rotation about at least one axis of rotation, the outer enclosure and the inner body comprise respectively an inner surface and an outer surface, separated by means of a viscous fluid, the outer enclosure is fixed to the main body of the spacecraft for rotation therewith once the harpoon is secured to the main body.
