摘要

Mapping the TGAM using a variation of the initial conditions made it possible to identify several important trajectories, including captures and escapes to/from the planetary system. It was also found that large values for the velocities of approach, on the order of 80 km/s, can result in captures by the planet. It is also shown that the energy variation is proportional to the orbital velocity of the moon and that it is independent form the length of the tether. The rotation angle plays an important role in defining the interval of the angles of approach that results in captures but has little influence on the range of approach velocities. In general, the technique presented here proved to give enough energy to perform the captures of a spacecraft coming from the Earth around any of the giant planets of the solar system without the help of any type of propulsion system.
