Experimental Studies on Mechanics of Lunar Excavation

One of the first construction operations for building a stationary habitat on the moon or Mars will be excavation of soil. The reasons for this necessity are manyfold and range from the need to protect inflatable habitats against radiation to creating an underground space for building electrical power plants. Despite the tremendous amount of earth movement that has taken place on this globe, a sound theoretical basis for designing soil-moving machines does not exist. This paper describes the results of experiments that were developed to evaluate empirically if and how soil could be excavated on the moon. No attempt has been made to optimize or promote a particular method. The goal of the present study is rather to establish a sound knowledge base to use for the more-detailed studies needed to design an operational system that will be successful on the moon.
