In 2023 a wooden satellite will be launched into space to study how wood will hold up in the vacuum outside our atmosphere.
By having wooden satellites it could be a great alternative to metal ones which will help cut down on space junk. Researchers and space experts from Kyoto University and a former Japanese astronaut, are working with the Sumitomo Group on the development and testing of special kinds of wood that can survive in the harsh environment of space.
“Since wood transmits electromagnetic waves and geomagnetism, if the artificial satellite is made of wood, an antenna and attitude control device can be installed inside the satellite, and the satellite structure can be simplified.”
“The wooden artificial satellites that enter the atmosphere after the operation is completed will be completely burned out. This will lead to the development of cleaner and environmentally friendly artificial satellites that do not generate minute substances (alumina particles) that can be a source of [air pollution] during combustion.”
Takao Doi told the BBC, “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,”
There are about 6,000 satellites orbiting the Earth now and over the years there will be more and more.
Kyoto University scientists hopes LignoStella will create a more sustainable alternative in satellites and cut down on space junk which could harm the earth in the future.
