中山大学“90后”学生带队自研立方星发射成功

Core Viewpoint - The successful launch of the "Yixian-A" satellite marks a significant milestone as the world's first satellite to validate wooden outer panels in orbit, with future plans for innovation in medical engineering integration [3][5]. Group 1: Satellite Development - The "Yixian-A" satellite, developed by a student team from Sun Yat-sen University, was launched on December 10 and is designed for scientific experiments, technology validation, and educational purposes, with a planned operational duration of six months [3]. - The satellite will conduct tasks including space imaging, testing of wooden outer panels, and development of software-defined satellite payloads based on Raspberry Pi technology [3]. - The team aims to develop a series of "Yixian" satellites, with a focus on breakthroughs in medical engineering integration [3]. Group 2: Team Leadership and Innovation - The lead of the "Yixian-A" development team, Wang Hui, is a PhD candidate at Sun Yat-sen University and has been instrumental in establishing the university's micro-nano satellite association [5]. - Wang Hui's innovative approach involved a "student-led design and management" model, breaking down the satellite development into manageable sub-projects to expedite the research process [5]. - The team faced technical challenges, particularly with the use of wooden outer panels, which required extensive experimentation to ensure durability in the harsh conditions of space [5][6]. Group 3: Material Innovation - The team collaborated with the College of Materials and the College of Advanced Manufacturing to leverage interdisciplinary innovation, experimenting with various types of wood and surface treatment techniques [6]. - Through numerous experiments, the team successfully identified suitable wood and treatment methods that enhanced the durability of the wooden materials, allowing them to withstand the extreme conditions of space [6]. - This achievement positions the team ahead of researchers from Finland, Japan, and other countries in the practical application of wooden satellite outer panels [6].
