After a short delineation of the planetary system and the basic mechanical laws governing the motion of bodies in space, three conspicuous classes of impulsive thrust trajectories of space vehicles are analyzed with respect to their characteristic parameters of velocity sum, rocket performance and travel time: class A, cotangential ellipses of major axis span, i. e. Hohmann ellipses; class B, intersecting ellipses of minor axis intercept; class C, intersecting conics of direct reflection intercept and of minimum travel time. The influence of the local gravity fields of the planets is allowed for. The mutual merits and limitations of these various trajectory classes are weighed against each other. The error analysis of the injection process is reviewed, and the potentialities of midcourse and terminal navigation are considered in this respect. A number of representative future space missions are compared with respect to rocket motor requirements and travel time.
