Abstract:

The motion of a space station in the neighborhood of the earth-moon libration points should be analogous with the motion of the asteroids of the Trojan Group in the sun-Jupiter-asteroid system. Lagrangian solutions of this phenomenon were provided by researchers by confining their mathematical treatment to an idealized problem, namely, the restricted three-body case. A study to determine the feasibility of placing and maintaining space vehicles in the neighborhood of these libration points has been undertaken which considers the realities of earth-moon space, such as oblateness of the earth, eccentricity of the moons orbit, solar pressures, effect of N-bodies, etc. Other factors that were considered are v hicle guidance to these regions and the reactive thrust necessary to maintain artificial stability. Plans were formulated for the placing of instrumented space packages within these regions to supplement the study and provide the essential data for future space ventures. Author
