Wood satellites
A Japanese company called Sumitomo Forestry is working with the University of Kyoto to develop the first wooden satellites.
The goal is to minimize the amount of debris that has built up in an orbit over the past few decades. BBC reports. According to the theory, satellites made of wood can simply burn up when they re-enter the Earth’s atmosphere.
“We are very concerned about the fact that all the satellites that penetrate the Earth’s atmosphere are burning and creating small alumina particles that will float in the upper atmosphere for years,” said Kyoto University professor Takao Doi, who told the International Space Station visited in 2008. has the BBC. “Ultimately, it will affect the earth’s environment.”
Orbital Yule Log
The researchers are currently investigating how different types of wood can withstand the extreme conditions in outer space. The materials must withstand extreme temperature fluctuations and an onslaught of radiation.
A proof of concept is in the works, as well as a model designed for future test flights, according to the BBC. However, Sumitomo forestry remains tight on any details.
The concept is reminiscent of an unused text for the 1992 movie “Alien 3”, which would have taken place on a wooden satellite.
Space Junkyard
According to the World Economic Forum, about 6,000 satellites currently orbit the earth – but only about 60 percent are actually used.
An increasing number of companies plan to launch their own satellite satellites soon to bring broadband to all parts of the world, which will significantly increase the clutter in the Earth’s orbit.
SpaceX alone has already sent 1,000 of its Starlink satellites into orbit. However, it chose to burn it again after it was no longer useful.
