Taking both a theoretical and observational perspective, this book is an introduction to recent developments in the field of celestial mechanics. It emphasizes the application to extended celestial bodies and devotes much attention to rotational aspects. In particular, it explains the state of art for accurate modelling of the rotation of celestial bodies such as the Earth, the Moon, and Mercury, which involves principles related to hydrodynamics and geodesy. Comparisons between the light curves of the asteroids and their rotational state are made and spatial techniques leading to the determination of the Earth's gravitational field are explained. Also, the book provides a general overview of the collisional processes in the solar system and of the dynamics of the rings. It is addressed to graduate students and researchers in space sciences and celestial dynamics.

Le but de ce livre est de présenter les développements récents du contrôle géométrique orienté vers la commande (notamment optimale) des véhicules spatiaux. Il est principalement destiné aux étudiants de 3e cycle et aux chercheurs, et son contenu a servi de base à une série de cours de contrôle et d'automatique enseignés à des étudiants de 3e cycle. Il s'appuie sur des projets de recherche avec l'ESTEC et le CNES, sur le contrôle d'attitude d'un satellite, le problème de transfert orbital en temps minimal, et le problème de rentrée atmosphérique d'une navette spatiale. Une première partie est consacrée à une introduction à la mécanique céleste, et la seconde au contrôle des véhicules spatiaux. Un dernier chapitre concerne les méthodes numériques dites indirectes, développées à partir  des études des auteurs: méthode de tir et algorithmes de calcul des points conjugués.
