Japan studies satellites made of wood to avoid “littering” into space



– In an effort to reduce space waste, Kyoto University is working with Japanese forestry company Sumitomo Forestry to develop the world’s first wooden satellite by 2023.

According to data, outer space currently contains more than 23,000 artificial debris in hand around the world, endangering active spacecraft. There are about 2,500 active satellites moving around the Earth today.

The idea that scientists are interested in is a device made of wood that can safely burn back to Earth.

Japan developed satellites made of wood to avoid litter into space

Professor Takao Doi, from Kyoto University and a Japanese astronaut, said he was worried that all satellites re-enter the Earth’s atmosphere on fire and produce tiny alumin particles. can float for several years in the atmosphere.

This step for Japan is of importance as countries are trying to develop environmentally friendly satellites to minimize space junk.

Sumitomo Forestry Company and Kyoto University will study tree development and the use of wooden products in spatial conditions. In addition, they are also trying to encourage technologies that use wood in the harsh conditions on Earth.

The biggest meaning of wooden satellites is that it will completely burn when it falls into the atmosphere, not spill waste on the ground, or form harmful substances that accumulate in the atmosphere.

“We are very concerned that all satellites return to the earth’s atmosphere and will burn and produce alumina (aluminum oxide) particles that have been floating in the upper atmosphere for many years. Ultimately, it will affect the earth’s environment, ”said Takao Doi, an astronaut and researcher at Kyoto University.

There are about 500,000 pieces of space waste floating in the orbit of the earth

According to the US Aerospace Agency (NASA), there are about 500,000 pieces of space waste floating in the orbit of the earth. These pieces travel at tremendous speed, enough to damage satellites, spacecraft and the International Space Station (ISS).

Experts have previously warned of the danger of unscrambled pieces of waste falling onto the earth, as more and more satellites are launched into space to cater to the growing needs of communications, television, and more. locate…

According to the World Economic Forum (WEF), there are nearly 6,000 satellites orbiting the earth, but 60% are no longer active, and considered as space waste.

Research firm Euroconsult estimates that an average of 990 satellites will be launched each year, meaning there will be 15,000 satellites in orbit by 2028.
