1. Modeling
The study of an interplanetary mission is based on the concept of a sphere of influence and the decomposition of the trajectory into a succession of two-body problems. This section presents the definition of the sphere of influence and recalls the formulas of Keplerian motion, in particular for liberation orbits.
1.1 Sphere of influence
A spacecraft in M is subject to the attraction of two stars in C 1 and C 2 . The three bodies, assumed to be point-like, are in gravitational interaction. The masses of C 1 , C 2 and M are m 1 , m...
