On April 23, the Second Lunar Sample Research Symposium and the Inaugural Meeting of the Second Lunar Sample Committee, hosted by Lunar Exploration and Space Engineering Center and organized by DHU, opened in Songjiang District, Shanghai. Bian Zhigang, Deputy Director of China National Space Administration; Xu Feng, Party Secretary of Science and Technology Commission of Shanghai Municipal Committee of the Communist Party of China; and Liu Chenggong, Party Secretary of DHU, attended the conference and delivered speeches.
The conference focused on the latest research results on lunar samples returned by the Chang’e-5 and Chang’e-6 missions under the Lunar Exploration Program. These include studies on the SPA massive impact on the lunar farside suggested by the Chang’e-6 samples; on the history of volcanic activities updated by isotopic geochronology; on the thermal evolution of the Moon reshaped by paleomagnetic analysis; on lunar dichotomy supported by comparative studies of Chang’e samples; and the composition and application research of lunar regolith. Cheng Yanhua, Researcher from the State Key Laboratory of Advanced Fiber Materials and the College of Materials Science and Engineering at DHU, delivered a presentation on behalf of her team: “Continuous Preparation and Application of Lunar Regolith Fibers for Lunar Surface In Situ Manufacturing.”

DHU has independently developed and built a 1.0 modular fiber-forming equipment that simulates the lunar microgravity environment, and successfully produced Chang’e-5 (CE5C1000) lunar regolith fibers with diameters of 10-50 µm. These fibers are currently on display at the National Museum of China as part of the exhibition “20 Years of Chinese Lunar Exploration Program.” A new generation of lunar regolith fiber-forming equipment is under independent development and construction. Once completed, it is expected to realize automated and continuous preparation of lunar regolith fibers under vacuum and vacuum-plus-microgravity environments, providing innovative materials with high reliability, lightweight characteristics, and environmental adaptability for the construction of China’s lunar research station.
