In a groundbreaking development, Japan has successfully launched the world's first wood-panelled satellite, LignoSat, to investigate the potential of wood as a sustainable material for future space exploration missions. Weighing just 900g, this innovative solar-powered satellite will spend six months orbiting the Earth after reaching the International Space Station on a SpaceX mission.

The launch of the world's first wooden satellite aims to revolutionize sustainable materials in space travel.
Developed by researchers at Kyoto University, LignoSat's panels are crafted from magnolia wood using traditional assembly techniques devoid of screws or adhesives. This pioneering effort seeks to explore the feasibility of replacing metals typically used in spacecraft with timber, which may flourish in environments devoid of water and oxygen—conditions found in outer space.
Professor Koji Murata from Kyoto University emphasizes that wood is more resilient in the harsh conditions of space than on Earth. “Wood is more durable in space than on Earth because there's no water or oxygen that would rot or inflame it,” he explained. He draws parallels to early 20th-century aviation, asserting that a wooden satellite is certainly achievable.
The research team hopes to determine if wood could be grown on extraterrestrial bodies such as the Moon or Mars to create habitats for future explorers. Although the LignoSat incorporates traditional aluminum structures alongside its wooden design, it carries sensors that will monitor the performance of wood under extreme space conditions.
Dr. Simeon Barber from the Open University commented on the novelty of the project, noting that while the satellite isn't entirely wooden, the concept deserves attention from a sustainability perspective. “The idea that you might be able to grow wood on another planet to help you explore space or make shelters is fascinating,” he said, while acknowledging the challenges in working with wood's variable properties.
He further highlighted that while wood has been utilized in space through components like cork in re-entry outer shells, using it for structural parts is complicated due to difficulties in predicting its strength. The Kyoto University team also hopes that wooden spacecraft could be less polluting when they burn up during re-entry compared to their metallic counterparts.
However, concerns about the increasing saturation of space junk persist, as experts agree that finding solutions to lessen spacecraft pollution remains a pressing issue. Dr. Barber cautioned that while using wood might mitigate some aspects of space debris, it could also necessitate carrying additional weight, challenging the sustainability narrative.
Ultimately, the LignoSat project not only opens new avenues for material science but also points towards the future possibilities of sustainable human habitation beyond Earth.
