In this paper the low thrust propulsion control strategy of the low energy Moon return transfer is researched. By establishing the dynamical equations in the elliptical four body problem, the characteristics of the low energy moon return trajectory is analyzed and the whole returning mission is divided into two sections, the moon escaping and the return manifold injecting. In each of the section,...
In this paper, a fast design and optimizing method of the low energy lunar escaping trajectory is introduced in the earth-moon elliptical four body system. Firstly, to find the optimal escaping conditions rapidly, the energy demand of the spacecraft is analyzed and it's found that when Moon is getting near its perigee and Sun becomes co-linear with Earth and Moon the escaping will consume the least...
The low energy moon return orbit has evident advantages in the fuel consumption but it's much sensitive to the initial states of the probe. To solve this problem, in this paper, the problem of accurate orbit control for low energy Moon return mission is studied. Firstly, based on the elliptical four body dynamical model, the dynamical characteristics of the low energy return orbit is analyzed. Then,...
