A dumbbell-shaped satellite whose elements are two mass points connected by a tether is examined. The moment of inertia of the satellite can be varied by varying the length of the tether. A three-step procedure for imparting spin to the system is proposed. First, the initially adjacent units are moved away from each other in the orbital plane extending the tether, thereby increasing the satellite's moment of inertia by several orders of magnitude. In the second phase, the gravitational moment imparts a kinetic moment to the satellite, leading to libration of the latter. In the third phase, the length of the tether is shortened to reduce the moment of inertia and ensure spin of the system. The dynamics of the procedure is analyzed, and the respective equations are derived.
