In a groundbreaking achievement, Japanese researchers have developed the world’s first wooden satellite named LignoSat. This satellite is set to be launched into space in September.
LignoSat is a collaborative project between Kyoto University and Sumitomo Forestry, a logging company. The development of the satellite began in April 2020.
The satellite, measuring 10 centimeters on each side, is made from magnolia wood. This wood was chosen for its strength and workability after space exposure tests on cherry, birch, and magnolia wood chips.
Traditional metal satellites create harmful debris when they burn up in the atmosphere, posing a risk to operational satellites and spacecraft. Wooden satellites like LignoSat aim to reduce this space debris by burning up completely upon re-entry into Earth’s atmosphere.
“Satellites that are not made of metal should become mainstream,” said Takao Doi, an astronaut and special professor at Kyoto University, emphasizing the need for sustainable satellite materials.
LignoSat is scheduled to launch on a SpaceX rocket from the Kennedy Space Center in September. It will be delivered to the International Space Station (ISS) for a series of tests.
Once deployed from the ISS, LignoSat will undergo tests to assess its strength and ability to withstand extreme temperature fluctuations. Data will be sent back to researchers to check for signs of strain and temperature resilience.
This pioneering project is a significant step forward in the fight against space debris. If successful, LignoSat could lead to the development of a new generation of environmentally friendly satellites.
Earlier reports in February 2024 highlighted LignoSat’s potential to combat space pollution and emphasized the use of magnolia wood for its beneficial burn-up properties, setting the stage for this innovative launch.
