"Celestial Mechanics" reviews the current state-of-the-art in the area of Space Dynamics and Celestial Mechanics. The contents have been divided into five parts. The first part contains articles related to Restricted Three Body Problem. The second part contains Satellite Theory, Non-linear motion and stability of two cable connected artificial earth satellites under perturbative forces. In the third part the Gravitational interaction between galaxies and motion of the moon is discussed in detail. The fourth part describes the General Celestial Mechanics, the theory of exo-solar planets confirming the migratory theory of planets and the Geometric Algebra an alternative approach to celestial mechanics. The book ends with the Moon Mission to be carried out by Government of India at Vikram Sarabhai Space Centre, Thiruvananthapuram. The Chapter "Non-traditional Trajectory Designs for Lunar Missions - An Approach for Chandrayaan-I" describes in detail the Moon Missions in different countries.
