中山大学“90后”学生带队自研立方星发射成功

Core Viewpoint - The article highlights the successful launch of the "Yixian-A" satellite, developed by a student team from Sun Yat-sen University, marking a significant achievement in the field of satellite technology and environmental innovation [3][5]. Group 1: Satellite Launch and Purpose - The "Yixian-A" satellite was launched on December 10, 2025, from the Jiuquan Satellite Launch Center, becoming the world's first satellite to validate wooden outer panels in orbit [3][5]. - The satellite is designed for scientific experiments, technology validation, and educational purposes, with a planned operational duration of six months [3][5]. Group 2: Development Team and Leadership - The project was led by Wang Hui, a postdoctoral researcher at Sun Yat-sen University, who founded the university's Micro-Nano Satellite Association in 2021 to facilitate satellite development [5][6]. - Wang's innovative approach involved a student-led design and management model, breaking down the satellite development into manageable sub-projects to accelerate progress [5][6]. Group 3: Technical Innovations - The use of wooden outer panels represents a bold innovation, aimed at reducing atmospheric pollution upon re-entry while facing challenges from extreme space conditions [5][6]. - The development team collaborated with various departments to experiment with different types of wood and surface treatments, ultimately enhancing the durability of the wooden materials for space environments [6][7]. Group 4: Future Plans - Following the success of "Yixian-A," the team plans to develop a series of satellites, including "Yixian-B," which will focus on biomedical experiments in space [3][5].
