Japan Launches World’s First Wood-Panelled Satellite

• 13 Nov 2024

On 5th November 2024, Japan launched LignoSat, the first wood-panelled satellite, marking a pioneering step in testing timber’s potential as a sustainable material for space travel.

Key Points

• Satellite Specifications: The cube-shaped satellite measures 4 inches on each side, weighs 900 grams, and is crafted from magnolia wood using a traditional Japanese technique without screws or glue.
• Durability Testing in Space: LignoSat will endure extreme temperature shifts, from -100°C to 100°C, as it orbits Earth.
• Researchers aim to examine how well wood withstands such conditions, including its resistance to radiation, which could impact onboard electronic components.
• Historical Use of Wood in Aerospace: Wood has played a significant role in early aviation, dating back to the 1900s when it was used in airplanes for its strength and lightweight properties.
• Wood’s resistance to decay in space, due to the absence of water and oxygen, adds further merit to its application in space technology.
• Environmental Benefits of Wood Satellites: Unlike conventional aluminium satellites, which generate aluminium oxides harmful to the ozone layer upon reentry, a wooden satellite like LignoSat is expected to minimize environmental impact, providing a renewable alternative in the growing satellite industry.
