On the morning of November 15th, the ninth batch of space science experiment samples from China's Space Station was delivered to the research team aboard the Shenzhou-21 spacecraft. The project, titled "Research on the Space Service Performance and Process Optimization of Simulated Lunar Soil Sintered Samples" and led by Academician Ding Lieyun, has achieved significant milestones. The first batch of "lunar soil bricks" has successfully returned to Earth after undergoing a one-year extravehicular exposure experiment, with both their overall condition and experimental data remaining intact.

For this project, a total of 74 lunar soil bricks were prepared. The sample unit numbered R5 has been retrieved, while the remaining samples continue their ongoing experiments. The research team will now carry out comparative analyses between the space-returned samples and those kept on Earth. The relevant findings from this study are expected to provide crucial support for the in-situ construction of lunar bases.

Notably, the "lunar soil bricks" demonstrate high compressive strength and feature a tongue-and-groove-like structure, making them highly promising candidates for lunar infrastructure construction.
