Abstract:

Escaping trajectories are investigated using a Poincaré map method in the circular restricted three body problem consisting of spacecraft, planet and moon. On the condition that Jacobi constant is fixed, the escaping trajectories are integrated back to the first periapsis from vicinity of  L-1 and L-2 and the escaping velocity of moon is obtained.

Key words: escaping , trajectory,  , circular , restricted , three , body , problem,  , Poincaré,  , section
