Mars In Situ Resource Utilization and Sulfur Concrete

, 2022
The NASA ISRU project establishes the need for in-situ materials for the lunar base and Mars habitation. Mars has the most favorable conditions for habitation and further deep space exploration. The understanding of planet conditions reveals that the temperature variations, solar radiations, and micrometeorite flux are much more favorable than the Moon

Research and prospect of in-situ utilization of lunar resources

Thermal Science
Lunar in-situ resource utilization (ISRU) is critical for sustainable exploration. This review analyzes three core technologies: regolith processing, additive manufacturing, and oxygen extraction. Lunar regolith serves as the primary source for metals, volatiles (e.g., H, ³He), and construction materials.
