SpaceX has launched the world’s first wood-paneled satellite into space “to test the suitability of timber as a renewable building material in future exploration of destinations like the Moon and Mars,” reports the BBC. From the report: Made by researchers in Japan, the tiny satellite weighing just 900g is heading for the International Space Station on a SpaceX mission. It will then be released into orbit above the Earth. Named LignoSat, after the Latin word for wood, its panels have been built from a type of magnolia tree, using a traditional technique without screws or glue. Researchers at Kyoto University who developed it hope it may be possible in the future to replace some metals used in space exploration with wood.
“Wood is more durable in space than on Earth because there’s no water or oxygen that would rot or inflame it,” Kyoto University forest science professor Koji Murata told Reuters news agency. “Early 1900s airplanes were made of wood,” Prof Murata said. “A wooden satellite should be feasible, too.” If trees could one day be planted on the Moon or Mars, wood might also provide material for colonies in space in the future, the researchers hope. Along with its wood panels, LignoSat also incorporates traditional aluminium structures and electronic components. It has sensors on board to monitor how its wood reacts to the extreme environment of space during the six months it will orbit the Earth. You can watch the launch on YouTube.
