Japanese Researchers Unveil World’s First Wooden Satellite
In a surprising turn of events, Japanese researchers have found a new and unexpected application for wood. The Japan Aerospace Exploration Agency (JAXA), in collaboration with NASA, is set to launch the world’s first wooden satellite, named LignoSat, into Earth’s orbit by summer 2024.
Crafted from magnolia wood and roughly the size of a coffee mug, this innovative satellite offers numerous advantages. Wood is lightweight, sturdy, durable, and biodegradable, making it an ideal material for space use. Unlike metal satellites, wooden ones disintegrate into fine ash upon reentry, minimizing the issue of space junk. In addition, wood proves to be more cost-effective compared to traditional satellite materials such as titanium and aluminum.
Despite wood’s susceptibility to moisture damage, successful tests conducted with three wood samples aboard the International Space Station (ISS) for ten months revealed no deformation, decomposition, or damage. This suggests that magnolia wood is well-suited for satellite use.
The project aims to open the door for incorporating wood into various space applications, signifying a promising leap for developing more sustainable spacecraft and potentially revolutionizing space exploration. NASA and JAXA are also engaged in initiatives to enhance spaceflight sustainability, including exploring cleaner rocket fuels and more efficient spacecraft designs. This vision extends to a future where wood becomes a pivotal material in crafting a range of spacecraft, from satellites to space stations and even spaceships.
