A Japanese corporate and Kyoto University have joined forces to develop what they hope would be the world's first satellites made out of wood by 2023.

Sumitomo Forestry stated it has begun research on tree growth and the use of wooden materials in space. The partnership will start experimenting with several types of wood in excessive environments on the planet.

Space junk is changing into a rising problem as more satellites are launched into the atmosphere. Wooden satellites would burn up without releasing dangerous substances into the environment or raining debris on the ground once they plunge back to Earth.

"We're very concerned with the truth that all the satellites which re-enter the Earth's atmosphere burn and create tiny alumina particles which will float in the higher atmosphere for many years," Takao Doi, a professor at Kyoto University and Japanese astronaut, mentioned in a statement. "Eventually it will affect the atmosphere of the Earth."

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

As an astronaut, he visited the Worldwide Space Station in March 2008. Throughout this mission, he became the first person to throw a boomerang in the house that had been specifically designed for use in microgravity.

Sumitomo Forestry, a part of the Sumitomo Group, which was founded more than 400 years in the past, stated it might work on developing wood supplies highly resistant to temperature changes and sunlight. The wooden it's utilizing is an "R&D secret" a spokesman stated in a statement. 

Space junk

Specialists have warned of the rising threat of space junk falling to the planet, as more spacecraft and satellites are launched as growing technology.

Satellites are more and more getting used for communication, tv, navigation, and weather forecasting. Space researchers and experts have been investigating different options to take away and reduce space junk.

There are almost 6,000 satellites circling Earth, based on the World Economic Forum (WEF). About 60 percent of them are defunct. Research agency Euroconsult estimates that 990 satellites shall be launched yearly 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 in the space area and has plans to deploy 1000's more.

Space junk travels at an extremely fast speed of more than 22,300 mph, so can have to trigger considerable harm 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.
