The authors discuss the landing capsule leaving the orbit by means of a tether without using jet engines. This system is modelled by symbolic dynamical equations of multibody systems. Active damping is provided by an actuator between the main body and the tether. The control parameters are optimized. The energy decay of the system is used as the performance criterion. The complex dynamics of the motion of this system is demonstrated in simulations with different initial conditions including structural vibrations. It is shown that an optimization process enables the control parameters be improved with respect to the dissipationof energy of longitudinal structural vibrations. The results of numerical analysis of the motion are presented in graphs.
