Wooden satellite LignoSat, constructed from magnolia wood, is set to be launched into space in September. This groundbreaking project is a collaboration between Kyoto University and Sumitomo Forestry aimed at reducing space debris by completely burning up upon re-entry into Earth’s atmosphere. The satellite measures just 10 centimetres on each side and 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.
Traditionally, satellites are made from metal, creating harmful debris when they burn up in the atmosphere. Wooden satellites like LignoSat are seen as a more sustainable alternative to reduce threats to operational satellites and spacecraft. Takao Doi, an astronaut and special professor at Kyoto University, believes that non-metal satellites should become mainstream to address space debris concerns.
The upcoming launch of LignoSat on a SpaceX rocket from the Kennedy Space Centre will mark a significant milestone in environmentally friendly satellite development. 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, LignoSat could lead the way for a new generation of satellites that are more eco-friendly and sustainable. This innovative project demonstrates a commitment to combatting space pollution and promoting the use of wood-based materials in space technology.
In conclusion, LignoSat is an exciting example of how non-metal materials can be used in space technology while being more sustainable than traditional metal materials used in satellite construction. The upcoming launch marks an important step towards reducing space debris concerns through innovative solutions like LignoSat that aim to create eco-friendly alternatives for future generations of satellites.
