The world of space exploration just got a bit more eco-friendly! Japan's Kyoto University has successfully launched LignoSat, the very first satellite with wood panels, weighing just 900 grams. Designed to test the durability of timber in extreme space conditions, this solar-powered satellite will orbit Earth for six months after its release from the International Space Station, courtesy of SpaceX.
LignoSat's panels are crafted from magnolia wood using traditional techniques that avoid screws and glue. Professor Koji Murata, a researcher involved in the project, emphasizes that wood's resilience in the vacuum of space—free from water and oxygen—makes it a viable alternative to metals.
"But don't get confused! The LignoSat isn't entirely made of wood," says Dr. Simeon Barber from the Open University. While wood has been used in spacecraft, like cork for re-entry protection, the challenge remains: wood's strength can be unpredictable.
The team imagines a future where wood could be cultivated on extraterrestrial surfaces, paving the way for renewable materials in space travel. While it could lead to less pollution during spacecraft re-entry, concerns remain regarding added weight and performance.
One thing is for sure: LignoSat is a pivotal step in merging sustainability with space exploration! Keep an eye on this wooden wonder as it orbits above us!
