Japan is developing wooden satellites to put into orbit in 2023



  • Kyoto University is working with the Japanese forestry company Sumitomo Forestry to develop a wooden satellite and put it into orbit.
  • The idea is that a device made of wood can burn safely when re-entered and can reduce space waste.
  • Space junk is attracting increasing attention from experts, who say it is harmful to the environment.

According to the BBC, Kyoto University is cooperating with a Japanese forestry company to develop wooden satellites to be launched into orbit by 2023 to reduce space junk.

Kyoto University professor and Japanese astronaut Takao Doi told the BBC that the advantage of a wooden satellite is that if it falls out of orbit and burns when it returns, it will not release as many harmful particles as metal satellites. .

“We are very concerned about the fact that all satellites that re-enter the Earth’s atmosphere will burn and produce tiny alumina particles, which will float in the upper atmosphere for many years. […] Eventually it will affect the global environment. “

Kyoto University and Sumitomo Forestry will begin experimenting with how different types of wood can withstand extreme conditions on the earth, in order to develop wood that can withstand drastic fluctuations in temperature and sunlight.

Space junk and debris are becoming a growing concern for experts. Daniel Oltrogge, director of the Space Standards and Innovation Center (CSSI), said: “Space debris is getting more and more attention. The collision zone of two huge space debris objects (ranging from 1

to 10 metric tons) Here comes the greatest environmental risk.” Although the estimates vary, Oltrogge said that CSSI believes that there are currently 760,000 objects larger than 1 cm in orbit.

This number is constantly increasing, especially when commercial companies launch their own satellite clusters. To date, Elon Musk’s SpaceX has launched nearly 900 high-speed Internet Starlink satellites, and plans to eventually launch 12,000 to 42,000.

Amazon is leading a similar project called Project Kuiper, which was approved by the FCC in July to launch 3,236 satellites.
