• LignoSat, built from honoki magnolia wood, launched by JAXA and Kyoto University in December 2024.
• First wooden satellite, weighing 900 grams, uses Japanese joinery techniques with no screws or glue.
• Designed to study wood’s response to space conditions during its six-month mission.
• Satellite will monitor wood’s durability, response to radiation, and ability to shield equipment from geomagnetic fields.
• Innovative design aims to replace conventional satellite materials like aluminum and titanium, reducing environmental impact.
• LignoSat burns completely upon re-entry, avoiding space debris and aluminum oxide formation.
• Kyoto University researchers suggest wood may be more durable in space without water or oxygen exposure.
• Findings could enable timber-based construction for space habitats on the Moon, Mars, and beyond.
• Project highlights the need for sustainable materials in space exploration and reducing long-term environmental damage.
