A pointing mechanism for use in an electric propulsion system of a spacecraft, the pointing mechanism comprises a mobile plate adapted to receive a thruster and defining a thrust vector of the thruster received on the mobile plate. The pointing mechanism further comprises a rotary actuator coupled to the mobile plate by means of a connecting element, the rotary actuator being configured to rotate the connecting element about a rotational axis of the rotary actuator such that the thrust vector defined by the mobile plate rotates about the rotational axis, wherein the thrust vector is inclined relative to the rotational axis.

A beam steering mirror device includes a mirror having an optical part with a reflecting or optical surface and a mirror body. The optical part is essentially thermally de-coupled from the body. A biaxial suspension of the mirror body has two rotation axes arranged essentially perpendicular with respect to each other and being located in a common plane. The suspension includes a set of four flexible pivots with a pair of pivots assigned to each rotation axis. The mirror is arranged with regard to the biaxial suspension such that its center of mass is approximately located in the intersection point of the two rotation axes. The device also includes motors for moving of the mirror body around the two rotation axes, sensors for determining the tilting angle of the mirror, and a housing for the mirror, the biaxial suspension, the motors and the sensors.
