Sustainably Made Space Satellites

Reduce, Reuse, Recycle AND REMOVE

Japanese scientists have developed the world’s first eco-friendly satellite constructed from wood, slated for launch in the later half of 2024.

This innovative small, cube-shaped spacecraft, called the LignoSat, is crafted from magnolia wood and assembled using traditional nail-free joinery techniques historically employed in constructing temples and shrines. The satellite represents the culmination of four years of meticulous research conducted by teams from Kyoto University and Sumitomo Forestry.

The LignoSat initiative aims to replace conventional metals and composite materials typically used in satellite construction with environmentally friendly wood. The satellite, measuring 10 centimeters on each side, features magnolia panels encasing a partially aluminum frame. Additionally, it is equipped with solar panels to support its compact design.

“Expanding the potential of wood as a sustainable resource is significant,” Takao Doi, Kyoto University professor and astronaut, told the Japan Times. “We aim to build human habitats using wood in space, such as on the moon and Mars, in the future.”
