Japan is building wooden satellites because there's too much junk in space

Japan plans a 2023 launch of the world's first satellite made out of wood

The group said it would work on creating and manufacturing wood materials that are highly resistant to temperature changes and to direct sunlight.

"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", Doi said.

As for the type of wood, Sumitomo Forestry is keeping mum. The advantage of a wooden satellite is that it would burn up during re-entry without leaving any junks behind in the orbit.

In this news, we discuss the Japan to build satellites made of wood by 2023 to cut down on space debris. The project aims to create wooden satellites that would burn up when they enter Earth's atmosphere without releasing harmful substances or showering debris on the ground, as is the case with the current satellites.

The problem of space clutter is only getting worse, as both Elon Musk's SpaceX and Amazon's Project Kuiper race to launch thousands of satellites into orbit to provide low-priced internet. Furthermore, wood contains organic compounds such as water that will evaporate in space, compromising its structural integrity.

Spaceships and satellites are largely made of metals like aluminum.

Doi added that "eventually it will affect the environment of the Earth". Professor Doi visited the International Space Station in March 2008 and became the first person to throw a boomerang in space that had been specifically designed for use in microgravity. It could be effective in dealing with the growing concerns about space junk.

According to the World Economic Forum, there are close to 6,000 satellites orbiting our planet, and about 60 percent of them are defunct and unused - basically space junk floating around and presenting various hazards to Earth's atmosphere. Elon Musk's SpaceX has launched nearly 900 of its high-speed internet Starlink satellites to date, and plans to eventually launch between 12,000 and 42,000. Of them, 955 satellites have already been launched with thousands more planned in the upcoming years. The research is also meant to come up with a wooden material that can be used in construction in extreme environments here on Earth. Meanwhile, astronomers have also expressed concern that these satellite constellations could potentially disrupt their ability to observe the cosmos. Space debris travel at fast speed - more than 35,000 kilometers per hour (22,300mph) - posing risk to around 3,300 expensive and important functioning satellites. Over the years, there have been numerous incidents involving collisions with satellite debris, including one where a piece of space junk collided with the International Space Station (ISS) and dealt damage to one of its heavily reinforced windows.
