It will be launched this year
Japan has created the world's first wooden satellite, which is about to be launched into space. LignoSat took about four years to build.
The project has been led by a joint research team from Kyoto University and forest processing corporation Sumitomo Foresty since April 2020. This was how they planned to demonstrate concern for the environment, since upon returning to Earth such a satellite would completely burn up into the atmosphere.
The satellite has dimensions of about 100 x 100 x 100 mm and a wall thickness of 4-5.5 mm. The design contains several aluminum parts, as well as solar panels. The total mass of the satellite is only 1 kg.
The satellite is assembled using Japanese traditional woodworking techniques, without the use of fasteners or glue. The satellite has been tested to be in outer space and will be launched this year on a SpaceX rocket.
