leader, Sumitomo Foresti
, said the woods She
began her research, in partnership with Kyoto University
, to grow trees whose wood will be used in the manufacture of the upcoming satellite.
The two cooperating parties will begin testing different types of wood, to determine their ability to withstand harsh conditions in space, according to the BBC.
The pioneering step aims to use biodegradable materials in space to confront the space waste crisis, which has become an increasing problem with dozens of countries launching more satellites every year.
When wooden satellites return to Earth, they will burn out without releasing harmful substances into the atmosphere, while their debris will not fall on our planet.
A professor at Kyoto University said the Japanese astronaut Takao Doi: “ We are very concerned about the fact that all the satellites that enter the Earth’s atmosphere burn out and leave small particles of alumina, which remain in the upper atmosphere for many years.”
He continued, “ In the end (this waste) will affect the earth’s environment.”
“The next stage will be developing the engineering model for the (wooden) satellite, and then we will manufacture the flight model,” Doi added.
Sumitomo Forestry, which was established more than 400 years ago, also announced that it will work to develop wood materials that are highly resistant to changes in temperature and sunlight.
A company spokesman said the wood it was using would be “kept secret”.
And space experts have warned of the increasing risk of space waste falling to Earth, as more spacecraft and satellites are launched for various purposes.
According to the World Economic Forum, nearly 6 thousand satellites orbit around the Earth, while about 60 percent of them have turned into “space junk” without jobs.
Research companies estimate that 990 satellites will be launched every year during the current decade, which means that by 2028 there may be more than 15,000 satellites around Earth.
And “space junk” swims at an amazing speed of over 35,000 kilometers per hour, so it can cause great damage to any object it collides with.
And in 2006, a small piece of waste collided with a station The space International, which caused a chip to shatter in one of its windows.
