On December 31, 2024, LignoSat, the world's first wooden satellite, was launched into space from the International Space Station. Developed by Kyoto University and Sumitomo Forestry, this innovative satellite is made from honoki wood using traditional Japanese techniques, aiming to test sustainable materials for future space exploration. Over its six-month mission, LignoSat will gather data on wood's performance in extreme conditions and may pave the way for future habitats on the Moon and Mars, while minimizing pollution compared to conventional metal satellites.
