Japan has pressed the button so that space does not turn into a giant garbage dump day by day. The wooden satellites to be developed will burn completely in the atmosphere without leaving any harmful substances.
It has been announced that the wood producer Sumitomo Forestry and Kyoto University are working together to develop the world’s first wood satellite. According to the BBC, this project could help reduce the amount of debris in space.
Every new satellite launched into Earth orbit becomes a very serious problem in terms of space debris. Although some of these satellites are burning in the atmosphere, it is a fact that they leave aluminum particles behind, creating a huge garbage dump in space. Wooden satellites to be developed by Japan will burn completely in the atmosphere without leaving any harmful substances behind.
Professor Takao Doi of Kyoto University on the subject: “We are very concerned that all satellites that reenter the Earth’s atmosphere will burn out, leaving behind tiny aluminum oxide particles that will drift into the upper atmosphere for many years. Ultimately this will affect the environment of our planet. We will first develop the engineering model of the satellite, then flight. We will produce the version. ” used the expressions.
They have a high risk
Today, satellites are used for communication, television broadcasting, navigation, and weather forecasting, and according to the World Economic Forum, there are almost 6,000 satellites in Earth’s orbit, of which about 60 percent are no longer working. Research firm Euroconsult estimates that 990 satellites will be launched each year in the current decade, which means their number in orbit could reach 15,000 by 2028. SpaceX alone has launched more than 900 Starlink satellites and plans to orbit thousands of satellites.
Satellite remnants can move at an incredibly high speed (more than 35,000 km / h), causing significant damage to the objects they collide with. For example, in 2006, a small piece of metal damaged the window on one of the ISS modules (picture above). As a result, experts and researchers around the world continue to explore various options for reducing debris in space.
