| This article gives an insight into the potential applications of rotating space tethers for the exploration of planetary satellites, pursuing a semi-analytic model that permits to study the influence of a tether in the design of orbits of interest for science missions. The averaging method allows to remove the fast time scales related to the tether?s rotation and the orbital motion, yielding to a model that successfully describes the very long term evolution of a tethered system for over months of mission. This model eases an initial analysis of the long term evolution of the tether?s attitude, unveiling a precession phenomenon of its rotation plane. Additionally, the model is applied to the search for frozen orbits, revealing promising orbit stabilization features that allow for the modification of frozen orbits by purely mechanical means, leading to lower eccentricity orbits for given altitude. Hence, it turns out that the length of the tether becomes an additional design parameter that shapes frozen orbits to fulfil tighter operational constraints. | |
