A Japanese startup Sumitomo Forestry merged with Kyoto and now they are developing unique satellite systems. Their peculiarity lies in the fact that an unusual material is used for their manufacture, namely wood. The representatives of the developer company said that they pursue only one goal: to minimize the amount of space debris in the orbit of our planet. Over the past decades, it has been massively accumulating and not being eliminated.
According to the developed theory, those satellites that are made of wood can burn out without a trace, entering the Earth's atmosphere. Takao Doi, a professor at Kyoto University, believes that the scientific world needs to be concerned about the amount of space debris on the planet and take measures to both eliminate it and reduce its volume.
Ultimately, the impact of space debris affects the state of the environment on the Earth. Now the researchers are figuring out what kind of wood can be the perfect raw material for making a unique space satellite. The material used for these purposes must withstand the extreme conditions of outer space.
First of all, they consist in temperature drops and in the powerful effect of radiation. It is not excluded that the selected wood material, if successfully tested, can later be used for test flights of spacecraft, and not just satellites. But the details of future plans, the researchers and the authors of the project have not yet been disclosed.
The experts of the World Economic Forum draw attention to the fact that now about six thousand satellites revolve around the Earth. Of these, only 60% are used for their intended purpose, and the rest are complex space debris.
Many companies from around the world are declaring their desire to launch their constellations of satellites for various purposes: to monitor the weather or to provide the Internet, but such development will only significantly increase the clutter and volumes of debris in our planet's orbit.
