GENERAL CONCEPTS ABOUT SOLID BODY ASTRODYNAMICS

Abstract

The paper presents the theoretical foundation of the dynamics of the solid body in gravitational movement in the outer space. It is known that the movement of solid bodies in space is subjects both the laws of Newton's classical mechanics and those of Kepler's celestial mechanics. Thus, the necessary conditions whom a solid body must fulfil to be able to leave the terrestrial surface and be launched into space are established. Also, the parameters that define the trajectories that solid bodies can have in the gravitational field are presented.
