Abstract

In this article we seek to illustrate how the understanding of the dynamics of some models of Celestial Mechanics allows both to explain some astronomical phenomena and to design realistic space missions. The paradigmatic model used is the restricted three-body problem in which the invariant manifolds of the so-called libration orbits, that is, periodic and quasi-periodic orbits around the collinear equilibrium points of the model, play a key role. We will describe some of these phenomena and mention a number of specific missions. Lastly, we will comment on other useful (and more sophisticated) models in Astrodynamics and we will conclude with a remark on how the tools of Dynamical Systems can be transferred from the macroscopic (celestial) world to microscopic ones, such as classic atomic physics.
