LignoSat is a 10cm cube made from magnolia wood. It weighs just 900g and was developed by scientists at Kyoto University. LignoSat has been ferried to the International Space Station on a SpaceX rocket from where it will launch into orbit for 6 months. Onboard sensors will monitor how LignoSat fares in the freezing vacuum of space. Its designers say it’s far more eco-friendly than traditional spacecraft.
LignoSat, a revolutionary satellite made from magnolia wood, has been launched into space. This tiny cube, weighing just 900 grams, was developed by scientists at Kyoto University and has been transported to the International Space Station (ISS) aboard a SpaceX rocket. From the ISS, it will orbit Earth for six months, testing the durability of wood in the harsh environment of space.
Unlike traditional satellites made of aluminum, which burn up on re-entry and release harmful metal particles into the atmosphere, LignoSat is designed to burn completely and safely, leaving no trace behind. Its eco-friendly design could reduce the environmental impact of space exploration, particularly as the space economy expands.
Wood offers surprising benefits for spacecraft. It is lightweight, strong, and doesn’t block radio waves, making it ideal for enclosing antennas and sensors. Unlike other materials, it prevents the formation of space debris by keeping all instruments safely inside its structure.
With the global space economy expected to grow from $630 billion in 2023 to $1.8 trillion by 2035, sustainable innovations like LignoSat are critical. This booming industry is set to create opportunities across various sectors on Earth while helping address some of the planet’s most pressing challenges.
