Japan has made history by successfully launching the world’s first wooden satellite, named LignoSat, into space. This groundbreaking initiative aims not only to explore innovative materials for space technology but also to contribute to eco-friendly solutions for space pollution. LignoSat, crafted from wood that shares material characteristics with samurai sword sheaths, represents a significant step toward sustainable space exploration, serving as a testbed for future timber-built missions to Mars. The satellite is set to remain in orbit for six months as part of its experimental mission.
