A Japanese start-up company called Sumitomo Forestry is working with Kyoto University to develop the first artificial satellites made of wood.
The goal is to minimize the amount of space junk accumulated in orbit over the past few decades, because BBC report. Theoretically, satellites made of wood could be burned when they re-enter the Earth’s atmosphere.
Kyoto University professor Takao Doi (Takao Doi) visited the International Space Station in 2008 and told BBC. “Ultimately it will affect the earth’s environment.”

Researchers are currently studying how various types of wood can withstand the extreme conditions of outer space. These materials will have to withstand extreme temperature fluctuations and radiation shocks.
According to the company, it is currently working on a proof of concept and a model designed for future test flights. BBC. However, Sumitomo Forestry remains silent on any details.

According to the World Economic Forum, there are currently approximately 6,000 satellites orbiting the Earth-but only 60% are actually in use.
More and more companies plan to launch their own satellite constellations soon to bring broadband to every corner of the world, which will greatly increase the chaos in the earth’s orbit.
SpaceX alone has put nearly 1,000 Starlink satellites into orbit. However, it has chosen not to use them before burning them.
