Japan to launch Lignosat, the world’s first wooden satellite

Marking a significant step towards eco-friendly space exploration, Japan and NASA are set to launch the world's first wooden satellite, aptly named LignoSat. This groundbreaking initiative aims to address the growing concerns of space debris and pave the way for a more sustainable future in orbit.

Lignosat: world's first wooden satellite

Traditional satellites, built with aluminum, release harmful particles when they re-enter Earth's atmosphere, potentially damaging the delicate ozone layer. LignoSat, however, will burn completely during re-entry, leaving no harmful trace behind.

Magnolia: The wood of choice

After extensive research, magnolia wood emerged as the ideal material for LignoSat. Kyoto University scientists conducted experiments by sending wood samples into space, where magnolia displayed exceptional workability, strength, and resilience in the harsh vacuum of low-Earth orbit.

The double benefit of Lignosat

Beyond its environmental advantages, LignoSat holds the potential to tackle the issue of space junk. Electromagnetic waves can easily pass through wood, allowing for the containment of instruments within the satellite's structure. This eliminates the risk of instruments detaching and becoming debris, contributing to a cleaner and safer space environment.
