华中科技大学“月壤砖”完成首年太空考验

Core Insights - The first simulated lunar soil sintered brick was showcased in China, marking a significant breakthrough in aerospace construction technology [1] - The lunar bricks were sent to space aboard the Tianzhou-8 cargo spacecraft for an outdoor exposure experiment, demonstrating the application of classroom technology in space [1] - The first batch of lunar bricks returned to Earth after a year of exposure in space, showing promising results for future lunar construction [1][2] Group 1 - The simulated lunar bricks were developed by a team led by Academician Ding Lieyun from Huazhong University of Science and Technology, utilizing real lunar soil components to create the material [1][2] - The bricks have a density comparable to ordinary bricks but possess over three times the compressive strength, indicating their potential for stable service in extreme lunar environments [1] - The first batch of returned samples consists of 74 small bricks, weighing approximately 1000 grams in total, with each brick weighing around 10 grams [2] Group 2 - The research team plans to conduct a three-year long-term testing experiment, with annual sample returns to analyze the performance of the lunar bricks in space [2] - The innovative approach proposed by the team involves using lunar solar energy to sinter lunar soil into bricks, which can be assembled on-site by robots, significantly reducing transportation costs [2] - The analysis of the returned samples will provide scientific evidence for predicting the long-term service behavior of lunar bricks on the moon [2]
