A Generalized Study of Two-dimensional Trajectories of a Vehicle in Earth-Moon Space results, has shown that the tolerance in direction of the initial geocentric velocity, to miss the Moon’s centre by its radius, has a mean value of approximately ± 0.2° about an initial value of 90°.

Factors Affecting the Accuracy of Impact Position of Satellites Re-Entered by Commandde of the perturbing impulse, and so in rocket propellant. In considering accuracy in azimuth, it is shown that the relation between the latitude of the orbital node and that of the impact point is of primary importance.

Aerodynamics of Trajectory Control for Re-Entry at Escape Speeden destination from the extremities of the entry corridor using wholly atmospheric modes of operation is found to require moderately higher lift/drag ratios than skip modes. However, the atmospheric cases do not suffer from the inherently sensitive guidance and control problems of the skip modes. An
