A lunar descent scheme with n periods of engine ON-OFF is investigated. Each period may have a different thrust level but it is constant for the length of the period. The engines are ingnited by altitude and cut off by velocity signals. Five groups of errors are considered: ignition altitude, velocity change, thrust level, lunar gravitation, and initial approach velocity. Equations are derived that allow the computation of the influence of any given error occurring during any one of the n periods on the final velocity at touchdown ...

The review surveys eight subdivisions within astrodynamics: geometry, coordinate systems and ephemerides; astrodynamic constants (including heliocentric, genocentric, lunar and planetary, and atmospheric constants); orbit determination; orbit perturbations (gravitational and nongravitational); orbit prediction (using both special and general perturbation techniques); applications (orbit selection and optimization, low thrust orbits, geocentric orbits, lunar, planetary and interplanetary orbits); observation theory; and attitude dynamics. Each subdivision is introduced and a number of the outstanding research papers in each area are mentioned. Specifically, an effort is made to delineate voids in our knowledge and to point up areas of profitable future research in astrodynamics. (Author).
