在月球上盖房子，如何 “白手起家”？

Core Viewpoint - The article discusses China's lunar construction plans, focusing on the development of lunar bricks made from lunar regolith, which will be tested in space to assess their viability for building on the Moon [1][4]. Group 1: Lunar Construction Challenges - Lunar construction faces significant challenges, including the need for structural stability, and the harsh lunar environment that demands high mechanical, thermal, radiation resistance, and durability from building materials [4]. - Transporting traditional construction materials like steel and concrete from Earth to the Moon is impractical due to high costs [4]. Group 2: Utilization of Lunar Resources - Chinese researchers propose using in-situ lunar resources, specifically lunar regolith, to create lunar bricks as a foundation for building a lunar base [7]. - Lunar regolith consists of loose particles covering the Moon's surface, formed by impacts, cosmic radiation, and temperature changes, with a thickness ranging from several meters to over ten meters [8]. Group 3: Lunar Brick Production - The composition of lunar regolith includes rock fragments, mineral fragments, glassy particles, and binders, primarily composed of silica, with varying mineral content across different regions [8]. - Researchers have created simulated lunar regolith to produce lunar bricks, employing a sintering process similar to traditional brick-making, which results in lunar bricks with compressive strengths exceeding 100 MPa [12]. Group 4: Testing and Future Prospects - The lunar bricks will undergo a three-year exposure test in space, with the first sample expected to return to Earth by the end of 2025, providing valuable data for future lunar base construction [14].
