Scientists have launched a satellite made from wood into space, marking a first in the world. The LignoSat satellite is orbiting Earth at 250 miles away, where researchers will test its sturdiness under harsh conditions over six months.
Developed by Kyoto University and timber company Sumitomo Forestry, the project aims to use locally produced wood as a sustainable material for space construction. Hoonoki, a type of Magnolia wood, was chosen for its strength and resistance to shattering.
The absence of water and oxygen in space protects the wood from fire or decay, while also testing its ability to shield semiconductors from radiation. The team plans to pitch their findings to SpaceX, with ambitions to use wooden satellites as a less polluting alternative to metal ones.
Their long-term vision includes using lunar and Martian wood for timber homes in 50 years’ time.
