A Program of Astronomy Research on the Moon and its Logistics Implications

This study concerns itself with one aspect of possible post-Apollo space activity—a program of astronomical research on the moon that culminates in the establishment of a lunar observatory. A mathematical model is utilized to analyze the logistics implications of conducting such an astronomical research program. The nature of the research equipment needed for the accomplishment of the program is outlined. Superposition of this research program upon a basic, long-term, lunar-base operations plan tentatively indicates that it could be feasible to conduct such a program of research during the 1970's and 1980's well within the constraints imposed by the logistics of presently planned spacecraft, boosters, and launching facilities. In an earlier study, a mathematical model was described that can be used to evaluate various aspects of the logistics supply support of space operations. The present study utilizes this model to investigate the implications of superimposing a set of demanding scientific requirements on an existing space base support plan. First, a scenario is developed for a lunar astronomical research program in sufficient detail to fulfill the input requirements of the model. The resulting scientific requirements are described in terms of the equipment and instrumentation desired in a temporal sequence of gradually increasing demands that culminates in the establishment of an astronomical observatory on the moon. These requirements then are superimposed on a supply-support system that provides for the establishment and operation of a manned lunar base over an eight-year period. Detailed input parameters consider such aspects as capacities of launch vehicles and spacecraft, earliest and latest delivery times for various supply and scientific modules, etc.The numerical results from two computer runs determine the necessary delivery schedules and provide an indication of the logistic cost of the postulated mission. For the specific astronomical example investigated, the results indicate that a lunar astronomical research program that culminates in the construction of a lunar-based observatory is logistically feasible. Further, such an observatory with sizable equipment could be established—without any unrealistic logistic requirements—within the next decades rather than during the next century.However, these numerical results are of secondary significance at this time. The primary importance of the study is the demonstration of a technique that permits the quantitative comparison of the logistical aspects of alternative space missions where many interrelated input parameters can be examined in parametric fashion to determine the sensitivity of the system to each.
