Japan is developing wooden satellites to put into orbit in 2023



  • Kyoto University and Sumitomo Forestry Corporation of Japan have developed a wooden satellite that can be put into orbit.
  • The idea is that a device made of wood can be safely burned when turning back and reduce the amount of space junk.
  • Space junk has attracted more and more attention from experts, who say it is harmful to the environment.

According to a report from the British Broadcasting Corporation (BBC) on Monday, Kyoto University is cooperating with a Japanese forestry company to develop wooden satellites to be launched into orbit in 2023 to reduce space debris.

Kyoto University professor and Japanese astronaut Takao Doi (Takao Doi) told the BBC that the advantage of a wooden satellite is that if it falls out of orbit and burns during re-entry, it will not release like a metal satellite. Many harmful particles.

Doi said: “We are very worried that all satellites that re-enter the earth̵

7;s atmosphere will burn and produce tiny alumina particles, which will float in the upper atmosphere for many years.”

Doi added: “Ultimately it will affect the global environment.”

Kyoto University and the Sumitomo Forestry Project plan to test the extreme conditions of different types of wood on the earth to develop a wood that can withstand severe fluctuations in temperature and sunlight.

Space junk and debris is an issue of increasing concern for experts.

Daniel Oltrogge, director of the Space Standards and Innovation Center, said: “Space debris is getting more and more attention, and the collision of two huge space debris objects (ranging from 1 to 10 metric tons) The biggest environmental risk.” Last month’s inside story.

Although the estimates vary, Oltrogge said that CSSI believes there are approximately 760,000 objects in orbit larger than 1 cm.

This number has been increasing, especially as commercial companies launch their own satellite constellations. Elon Musk’s SpaceX has launched nearly 900 Starlink high-speed Internet satellites, and plans to eventually launch 12,000 to 42,000.

Amazon is leading a similar project called Project Kuiper. It was approved by the Federal Communications Commission in July to launch 3,236 satellites.
