A #Japanese company, in conjunction with the #University of #Kyoto, is working on creating the first satellites made of wood, with the intention of making them more friendly to the terrestrial ecosystem at the end of their useful life.

#He space debris problem it is real and increasingly serious. #According to a study by the #Center for #Space #Standards and #Innovation, there are believed to be more than 760,000 orbiting objects larger than 1 centimeter. #As more satellites and parts of older ships stop working and are left in space, this problem will continue to get worse.

#This is why some companies and space agencies work on their own solutions. The ESA from #Europe#For example, you are developing a ship that would collect the largest pieces of space junk. #However, researchers at the #University of #Kyoto and the #Sumitomo #Forestry company are working on a solution that could be really practical: wooden satellites that completely disintegrate when they re-enter the atmosphere, after their useful life.

#Currently, the pieces of space junk that fall to earth I know set fire and disintegrate, but that does not mean they do not pose a long-term risk of pollution to the planet, according to #Takao #Doi, a professor at #Kyoto #University and an astronaut who visited the #International #Space #Station in 2008. “We are very concerned that satellites #When they re-enter the #Earth’s atmosphere, when they catch fire, they leave small particles of alumina that can remain in the atmosphere for many years, ”said #Doi.

#This is why they are experimenting with different types of wood to create satellites, developing wood-based materials that can withstand drastic changes in temperature and sunlight. The next step in your research will be to develop the engineering model for the satellites and then build some test models. #Hopefully, in a few years #Japan could put the first partially green satellites in history into orbit.
