Optimum thrust-limited orbit transfer in strong gravity fields,ve a constant thrust magnitude which is much smaller than the force of gravity. The method of averaging is used to determine optimum transfers in three spatial dimensions. Five integrals are obtained for the tenth order system of canonical equations of optimal motion. These integrals are theoretical
