Japanese researchers have unveiled a groundbreaking project in collaboration with the Japan Aerospace Exploration Agency (JAXA) and NASA. The result is the world’s first wooden satellite called LignoSat, set to be launched into Earth’s orbit by summer 2024.
Crafted from magnolia wood, the innovative satellite offers several advantages over traditional metal satellites. It is lightweight, sturdy, durable, and biodegradable, addressing the issue of space junk as it disintegrates into fine ash upon reentry. In addition, wood is more cost-effective compared to materials such as titanium and aluminum.
Despite initial concerns about wood’s susceptibility to moisture damage, successful tests conducted with three wood samples aboard the International Space Station (ISS) for ten months showed no deformation, decomposition, or damage. This suggests that magnolia wood is well-suited for satellite use.
The project aims to pave the way for incorporating wood into various space applications and signifies a promising stride toward developing more sustainable spacecraft, potentially revolutionizing space exploration. NASA and JAXA are also involved in initiatives to enhance spaceflight sustainability, including exploring cleaner rocket fuels and more efficient spacecraft designs. The 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.
