- Kyoto University is collaborating with the Japanese forestry company Sumitomo Forestry to develop a wooden satellite to be sent into orbit.
- The idea is that a device made of wood can burn safely on re-entry and will create less scrap space.
- Space waste is becoming a growing concern among experts, who say it poses an environmental risk.

Kyoto University is collaborating with a Japanese forestry company to develop wooden satellites for launch into orbit by 2023 in an effort to reduce space waste. BBC Reports.
Kyoto University professor and Japanese astronaut Takao Doi told the BBC that the advantage of the wooden satellite is that if it fell from orbit and burned upon return, it would not release as many harmful particles as metallic satellites.
“We are very concerned about the fact that all the satellites that enter the Earth’s atmosphere again burn up and create small alumina particles that will float in the upper atmosphere for many years. […] “Ultimately it will affect the earth’s environment,” Doi said.
Kyoto University and Sumitomo Forest will begin experimenting with how different wood species can withstand the harsh conditions on Earth with the goal of developing wood that can withstand wild fluctuations in temperature and sunlight.
Waste and space debris are becoming a growing concern among experts. “Space debris is a growing concern, and the collision of two massive space debris objects – ranging in weight from one to ten metric tons – poses the greatest environmental risk,” said Daniel Ultrog, Director of the Center for Space Standards and Innovation (CSSI). Interested in the business. Although estimates vary, Oltrogge said CSSI believes there are 760,000 objects larger than a centimeter in orbit at the moment.
This number is constantly increasing, especially as commercial companies launch their own satellite towers. Elon Musk’s SpaceX has launched nearly 900 of its Starlink high-speed satellites online to date, and plans to launch between 12,000 and 42,000 eventually.
Amazon is leading a similar project called Project Kuiper Received FCC approval In July to launch 3,236 satellites.
