Paragraph starter
The Cold Sintering Process (CSP) presents a significant advancement for in-situ resource utilization in extraterrestrial environments. By enabling the densification of materials at low temperatures (below 300 °C) through pressure-assisted dissolution-precipitation, CSP offers a low-energy pathway to fabricate structural components. Research indicates the potential to produce high-strength regolith bricks exceeding 200 MPa, which is crucial for constructing load-bearing structures on celestial bodies like the Moon and Mars, thereby reducing the logistical burden of transporting materials from Earth.
