Summary

Japan launched the world’s first wooden satellite, LignoSat, to test if wood can function as a space-grade material. Developed by Kyoto University, the satellite is made of honoki wood, chosen after a 10-month ISS experiment proved its suitability for space.

Designed without screws or glue, LignoSat will orbit Earth for six months, enduring extreme temperature swings and measuring wood’s resistance to space radiation. Advocates highlight wood’s eco-friendly re-entry properties compared to metal.

Researchers envision wooden structures for future space habitats, potentially boosting the timber industry.
