Abstract: Axial penetration of the lunar surface was performed to collect soil samples with drive tubes and drill cores on the six successful Apollo missions. Although the pile-driving and drill penetration methods were used for exploration tasks to collect core samples they will also be used for lunar construction tasks. Three penetration devices that can be scaled for use on the moon are presented in this paper and each of the devices is analyzed from a work-based approach and a cost-based approach. From these analyses, we make a summary of the costs to dig holes on the moon.
