Space debris could be reduced with wooden satellites – Latest news, Breaking news, Top news

Space debris is becoming an increasing problem as more gadgets are thrown into the atmosphere. Today, there are nearly 6,000 satellites orbiting the Earth and, according to the World Economic Forum, around 60 percent of them are unwanted space.

The problem will get worse. The research firm Euroconsult estimates that an additional 990 satellites will be launched each year in this decade. If correct, there could be 15,000 satellites in orbit by 2028. And it’s a very conservative estimate, given that a single project, Elon Musk’s Starlink Space Internet, has permission to launch 12,000 units.

All satellites that re-enter the Earth’s atmosphere burn and create small particles of alumina that will float in the upper atmosphere for many years, ultimately affecting the Earth’s environment. On the other hand, space debris travels at an incredibly fast speed of over 35,000 kilometers per hour, which can cause considerable damage to any object it hits, including the ISS or the space exploration craft.

Wooden satellites against space debris

Japanese company Sumitomo Forestry is working with researchers at Kyoto University to develop the world’s first wooden satellites. The general idea is for wooden satellites to burn without releasing harmful substances into the atmosphere or to rain debris on the ground when they return to Earth.

At the moment, they are investigating the growth of trees and the use of these types of materials in space. The association will start experimenting different types of wood in extreme environments on Earth. The type of material is kept secret, but I think it will be very resistant to temperature changes and sunlight. Then a wooden satellite engineering model will be developed and then a flight model will be created.

We will see the result. At least it’s a test. Satellites are increasingly used for communications, television, navigation or weather forecasting. Space experts have researched various options for eliminating and reducing space debris, as well as electronic debris, another major environmental problem, a huge cost to the global economy and the significant loss of essential resources such as earth metals. rare, copper or gold.
