A major frontier of space exploration is to construct permanent bases and test beds for future lunar and Martian exploration. Two essential components are in situ resource utilization and surface mobility. In situ resource utilization describes the usage of native lunar and Martian materials to reduce construction costs on site. Surface mobility is study of the interaction between soil and vehicle traction systems to develop effective lunar or Martian vehicles. Both of these entities call for a thorough understanding of the mechanical and engineering properties of lunar and Martian soils. However, only limited information has been gained so far with regard to the physical and mechanical properties of lunar and Martian soil. This dissertation discusses the development of a new miniature triaxial testing device to investigate the shear strength of dry cohesionless soil (lunar soil and lunar simulants) of less than 10 g, and comparisons are made between the testing results and that achieved through conventional triaxial tests to confirm the validity of the device. In addition, a light weight Martian soil simulant, CWRU-1, was also developed for large quantity application for the study of high shrinkage mobility tests. CWRU-1 was mechanically characterized via laboratory experiments and compared to characterizations of Martian soil and previously developed Martian soil simulants.
