This study concerns itself with one aspect of possible post-Apollo space activity -a pro­ gram 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 na­ ture of the research equipment needed for the ac­ complishment of the pr...
