Burning Up Space Debris: A Wooden Satellite Takes Off to Help Save the Environment

A groundbreaking collaboration between Kyoto University and Sumitomo Forestry is set to launch a wooden satellite, LignoSat, into space in September. This tiny wooden satellite, constructed from magnolia wood, aims to reduce space debris by burning up upon re-entry into Earth’s atmosphere.

LignoSat was chosen for its strength and workability after conducting space exposure tests on cherry, birch, and magnolia wood chips sourced from Sumitomo Forestry’s company forest. The upcoming launch of LignoSat on a SpaceX rocket from the Kennedy Space Centre marks a significant milestone in environmentally friendly satellite development.

The innovative project demonstrates a commitment to combatting space pollution and promoting the use of wood-based materials in space technology. If successful, LignoSat could lead the way for a new generation of satellites that are more eco-friendly and sustainable.

Takao Doi, an astronaut and special professor at Kyoto University, believes that non-metal satellites like LignoSat should become mainstream to address space debris concerns. He argues that traditional metal satellites create harmful debris when they burn up in the atmosphere, making wooden satellites like LignoSat a more sustainable alternative.

Once deployed to the International Space Station (ISS), the satellite will undergo rigorous tests to evaluate its strength and ability to withstand extreme temperature changes. Data transmitted from LignoSat will be analyzed by researchers to assess its performance in space conditions. If successful, this innovative project could pave the way for a greener future in space technology.
