Japan is developing the world’s first satellite made of wood

The Kyoto University and a private Japanese company have partnered to develop the world’s first satellites made out of wood by 2023.

The company –Sumitomo Forestry said it has started research on tree growth and the use of wood materials in space.

The partnership will begin experimenting with different types of wood in extreme environments on Earth.




“We are very concerned with the fact that all the satellites which re-enter the Earth’s atmosphere burn and create tiny alumina particles which will float in the upper atmosphere for many years,” Takao Doi, a professor at Kyoto University and Japanese astronaut.

“Eventually it will affect the environment of the Earth.”

“The next stage will be developing the engineering model of the satellite, then we will manufacture the flight model,” Professor Doi added.



Experts have warned of the increasing threat of space junk falling to Earth, as more spacecraft and satellites are launched.

Wooden satellites would burn up without releasing harmful substances into the atmosphere or raining debris on the ground when they plunge back to Earth.

Satellites are increasingly being used for communication, television, navigation and weather forecasting. Space experts and researchers have been investigating different options to remove and reduce the space junk.

There are nearly 6,000 satellites circling Earth, according to the World Economic Forum (WEF). About 60% of them are defunct (space junk).

Research firm Euroconsult estimates that 990 satellites will be launched every year this decade, which means that by 2028, there could be 15,000 satellites in orbit.

Elon Musk’s SpaceX has already launched more than 900 Starlink satellites and has plans to deploy thousands more.

Space junk travels at an incredibly fast speed of more than 22,300 mph, so can have cause considerable damage to any objects it hits.

In 2006 a tiny piece of space junk collided with the International Space Station, taking a chip out of the heavily reinforced window.
