The establishment of secure earth-independent long-term lunar habitats has been envisioned by numerous government agencies and private companies. Recent advancements in assessing seismic hazards caused by shallow moonquakes have highlighted the importance of incorporating this phenomenon into the design of robust and resilient lunar structures. However, further research is required to explore lunar habitat design that considers seismic loads. This paper proposes assessing the structural response of a lunar habitat made of sulfur concrete covered with a regolith layer. The numerical model of the structure is subjected to gravitational, internal pressure and seismic loads. The seismic analysis of the structure is carried out using spectral and nonlinear time history methods. Conditional mean spectra for shallow moonquakes with return periods of 75, 475, 970 and 2475 years are used in the seismic analysis. The records used for the temporal analyses were ground motions that agree with a preliminary seismic hazard on the Moon. The results of temporal analyses reveal that shallow moonquakes with return periods greater than 475 years can lead to the loss of the global stability of the structure. Consequently, the findings imply that seismic loads have the potential to impose unacceptable demands on lunar structures constructed from in-situ materials like sulfur concrete. Hence, it is imperative to incorporate seismic considerations in the design process for developing resilient and long-term lunar habitats.

The need to build a long-term or even permanent base is now a significant concern with the development of the exploration of extraterrestrial celestial bodies. Sulfur concrete was first proposed as a new building material in the 20th century. Recently, sulfur concrete has attracted much interest, as sulfur is considered one of the most accessible resources on the Moon and Mars, thanks to the in-situ resource utilization methodology. In addition, sulfur concrete is one of the most promising building materials for improving terrestrial sustainability or extraterrestrial exploration. So far, reviews have only focused on developing sulfur concrete and extraterrestrial building materials. This review paper summarizes the history of sulfur concrete development and different modified sulfur concretes. Previous research on extraterrestrial building materials is also reviewed. The unique advantage of sulfur concrete as an extraterrestrial material is justified, as no water is used during mixing. Lunar and Martian soil simulants are also examined as possible aggregate types. Finally, further improvements are proposed to broaden the application of sulfur concrete and the corresponding treatments. The possibility of recyclability and circularity is discussed from a sustainable development point of view. This review article provides readers with a detailed overview of sulfur concrete and its history, why it is more promising and accessible as an (extra)terrestrial building material, the challenges of its future application, and corresponding treatments to overcome the obstacles.
