It was reported on December 31 that Kyoto University and Sumitomo forestry company in Japan are promoting plans to launch the world’s first wooden man-made satellite in 2023. The utility model is characterized in that it can be burned out in the atmosphere after use, and the burden on the environment is small. The research team will first start an experiment to expose wood to space and confirm its persistence in February next year.
The research team plans to build a small cube satellite with a side length of about 10 cm. The structure with wood and Cecep Solar Energy Co.Ltd(000591) battery covering the outside is adopted, and the electronic circuit board is placed inside. Because the wood will not shield the electromagnetic wave, the antenna can be placed inside. It also has the advantages of low material cost and easy processing. The research team also plans to recommend to the Japan Aerospace Research and Development Agency (JAXA).
At present, aluminum is the mainstream of satellite materials. When entering the atmosphere after the mission, alumina particles may be generated, and the particles reflect sunlight, which may cause climate effects such as the decline of earth’s temperature.
