An orbit transfer system that transports a payload from LEO to GEO using multi-stage spinning tethers is studied in this paper. We propose a tether configuration called “Balance Tether.” The variations in the total mass and mission duration of the system are analyzed for different numbers of stages and different lengths of tethers. In addition, the possibility of debris impact damaging each of several tether system configurations is also analyzed. As a result, we obtain the guidelines for a system design that minimizes total system mass while also taking into account the system lifetime as limited by debris impact. In addition, it is shown that the Balance Tether can reduce the total system mass compared to a single-tether system. The results also show the effectiveness of the spinning-tether system as compared to a conventional chemical propulsion system for the same orbit transfer mission.
