In December 2024, five CubeSats were released into Earth's orbit from the International Space Station (ISS), marking a significant milestone for space innovation. Among these satellites was LignoSat, an experimental wooden satellite developed by the Japanese Aerospace Exploration Agency (JAXA). This unique project explores the feasibility of using wood as a sustainable material for spacecraft construction.
Prior to LignoSat's deployment, an experiment aboard the ISS tested three species of wood in the harsh space environment. Researchers assessed their durability and performance to identify the most suitable option for the satellite's construction. Honoki magnolia wood was ultimately selected due to its resilience, and the satellite's panels were crafted using a traditional Japanese wood-joinery technique.
Equipped with sensors, LignoSat is designed to measure various environmental effects on its wooden structure. These include strain, temperature fluctuations, and exposure to space radiation. The satellite also features instrumentation to monitor geomagnetic levels, evaluating whether Earth's magnetic field can penetrate the wooden body and impact the satellite's systems. The data collected will provide critical insights into the viability of wood in space applications.
This research could pave the way for innovative and eco-friendly approaches to satellite manufacturing, potentially reducing reliance on conventional materials that have a larger environmental footprint.
