摘要

Due to limiting space and mass humans can bring with them to the Moon or Mars, in situ resource utilization (ISRU) is needed to reduce the cost of manned missions. Regolith is the most readily available resource and could be utilized as a construction feedstock material via sintering. Over the last two years, Pacific International Space Center for Exploration Systems (PISCES) has been sampling and characterizing Hawaiian basalt aggregate and testing the effects of composition on sinterability. Hawaiian basalt is chemically and mineralogically similar to Lunar/Martian regolith, making it an excellent simulant. PISCES' work has focused on sintering profiles at 1,149°C and 1,177°C. Depending on sample composition, the structural results of the sintered materials varied from extremely poor to comparable or better than specialty concrete. In this paper, we discuss how PISCES' research has expanded to include polished thin section analysis of the sintered material and the effects that glass and olivine have on sinterability. Structural, mechanical, and thermodynamic testing such as thermal conductivity, heat capacity, thermal shock, absorbency, hardness, compressional, and flexural strength have also been included.
