[deep research] "全球首颗木质卫星LignoSat：探索可再生材料在太空的潜力与环境影响"

LignoSat, the world’s first wooden satellite, was developed through a collaboration between Kyoto University and Sumitomo Forestry, aiming to reduce space debris and environmental impact in an era of increasing satellite launches. It was launched on November 5, 2024, from Kennedy Space Center aboard a SpaceX Falcon 9 rocket and successfully arrived at the International Space Station (ISS) in December 2024 for initial tests. Scheduled to be released in January 2025 for a six-month space evaluation, LignoSat will assess the structural integrity of wood under extreme space conditions, such as temperature fluctuations and radiation. This project challenges traditional satellite design, which heavily relies on metals, by exploring renewable materials that burn upon re-entry, thus minimizing harmful debris. LignoSat signifies a shift towards sustainability in aerospace, potentially influencing future satellite designs and manufacturing practices. Its success may lead to a broader adoption of
