Space tether system is a promising technology that can be applied to solve many practical problems of astronautics. This work is devoted to the study of a space tether system dynamics under the influence of the atmosphere on end bodies. An original approximation of the atmosphere density is proposed. This approximation allows to obtain a new analytical solution describing the space tether oscillations. The stationary equilibrium positions of the system are found. The problem of the space tether system spin-up using aerodynamic drag is considered as an example of applying the obtained solution. It is proposed to put the system into rotation mode by inflating a large cross-section balloon at its lower end. An analytical expression that determines the required balloon cross-sectional area is obtained. Numerical simulation confirms the correctness of the analytical result.
