In December 2024, the Japanese Aerospace Exploration Agency (JAXA) launched LignoSat, a pioneering wooden satellite, into orbit from the International Space Station. This innovative project aims to assess wood as a sustainable alternative to traditional satellite materials by evaluating its performance in space conditions such as radiation and temperature. LignoSat is constructed from honoki magnolia wood, utilizing traditional Japanese joinery techniques to create 10 cm-long panels without glue or nails.
Prior to the launch, experiments were conducted aboard the space station to test the durability of three wood types under space conditions. By deploying sensors on LignoSat, researchers will monitor strain, temperature, and radiation effects, while also evaluating geomagnetic levels to see if they interfere with the satellite’s functionalities. The mission signifies a crucial step in exploring eco-friendly solutions for space technology and could lead to advancements in sustainable satellite construction. This endeavor not only underscores the potential of biodegradable materials in space applications but positions LignoSat as a testbed for future innovations within the aerospace sector.
