Japanese Researchers Launch World's First Wooden Satellite 'LignoSat'
日本の研究者たちは初めて木製衛星『LignoSat』を軌道に打ち上げました。この革新的な装置は、2024年11月5日に打ち上げられ、完全に木材で作られており、特に伝統的に刀を作るために使用される本木材でできています。LignoSatは軌道上にあり、地球から約400キロメートルの高さに位置しています。その主な目的は、木材の耐久性と持久性を宇宙でテストすることです。
この木製装置の特別な特徴は、大気圏に再突入するときに完全に燃焼し、害のある残留物や汚染物質を残さないことです。これにより、宇宙の汚染や破片を減らすことができます。
科学者たちは、将来的に月面や火星に木製の居住区やインフラを建設することが可能になると楽観的に考えています。このブレークスルーは、宇宙研究における持続可能な革新への道を開き、衛星建設における先駆的な機会を生み出しました。
