The mention of magnolia, birch, or cherry wood often evokes thoughts of furniture, yet Japanese researchers have unveiled an unexpected application for wood. In a joint effort between the Japan Aerospace Exploration Agency (JAXA) and NASA to enhance spaceflight sustainability, they are set to launch the world's first wooden satellite, named LignoSat, into Earth's orbit by summer 2024.
Crafted from magnolia wood and resembling a coffee mug in size, this innovative satellite offers numerous advantages. Wood proves to be lightweight, sturdy, durable, and biodegradable, avoiding burning or rotting in space. Unlike metal satellites, wooden ones, like LignoSat, disintegrate into fine ash upon reentry, mitigating the issue of space junk. Additionally, wood is more cost-effective compared to traditional satellite materials such as titanium and aluminum.
Despite wood's susceptibility to moisture damage, researchers conducted successful tests with three wood samples aboard the International Space Station (ISS) for ten months, revealing 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. The launch of LignoSat signifies a promising stride toward developing more sustainable spacecraft, potentially revolutionizing space exploration.
Beyond LignoSat, NASA and JAXA are engaged in several initiatives to enhance spaceflight sustainability, including the exploration of 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.
