| Abstract | Innovative building materials and techniques that take advantage of in situ resources utilization (ISRU) for the sustainable development of extraterrestrial habitats are required to achieve sustainable human activity on the Moon and Mars. However, for space constructions, the conventional construction methods on Earth are not practical in such extreme environmental conditions and logistical limitations, so new construction materials based on regolith are studied, such as regolith-based concrete, geopolymer, and biopolymer (biocomposites). The use of locally sourced aggregates and alternatives to binders in 3D printing (additive manufacturing) such as alkali-activated geopolymers and protein-based biobinders with promising mechanical properties poses challenges for their scalability and their resistance to extraterrestrial stressors. Ensuring the structural integrity and longevity of space habitats is fundamentally important for the adaptation of concrete mixtures in space conditions of microgravity, vacuum, radiation and thermal cycling. Continuing experimental initiatives like NASA's 3D Printed Habitat Challenge prove the viability of critical technologies and demonstrate the significance of robotic automation, digital twin modelling and sensor integration in quality assurance and lifecycle management. Although remarkable advances have been made, there are still gaps in knowledge on processing, material stability and energy-efficient operation, highlighting the need for multi-disciplinary collaboration to achieve resilient, sustainable human settlements beyond Earth. |
