A satellite made of wood. Sounds crazy, right? But scientists in Japan are giving it a shot. They're sending a small, wooden satellite called LignoSat to the International Space Station. Why wood? Well, metal satellites leave behind harmful particles when they burn up. Wood, especially from the honoki magnolia tree, might be a safer, renewable option.
LignoSat will spend six months in orbit, around 250 miles above Earth. It's not all wood, though. There's some aluminum and electronic parts inside. But if it works, wood could replace metal in satellites. "Early planes were made of wood, " says Professor Koji Murata. "So why not satellites? "
Wood might not be used for super-important parts. But it could be the future. "Metal satellites might be banned, " says astronaut Takao Doi. They're hoping to convince SpaceX to use wooden satellites. And one day, maybe we'll grow trees on the moon or Mars!
