Wood in Space: A Breakthrough Approach
Scientists are exploring the use of wood as a material for satellites to address the growing concern of non-biodegradable space debris. Unlike traditional materials, wood does not burn or decompose in the vacuum of space. However, it will burn upon reentry into Earth's atmosphere.
Successful Testing on the International Space Station (ISS)
After successful testing of wood samples aboard the International Space Station earlier this year, researchers concluded that the wooden satellite is fit for launch. The experiments involved three wood types: magnolia, cherry, and birch. Despite temperature variations and intense space radiation, the wood samples showed no deformation or surface damage.
Choosing Magnolia for Durability
Magnolia was selected for its resilience during processing, minimizing the risk of the satellite breaking apart during fabrication. The scientists determined that magnolia could withstand the challenges of space without compromising structural integrity.
Addressing Space Debris Concerns
Currently, there are approximately 8,440 metric tons of objects in low Earth orbit, including dead satellites and remnants of used rocket stages. Metal debris, such as titanium and aluminum, contributes to additional light pollution, hindering astronomers' observations. Wooden satellites are expected to generate less debris and fully burn up in the atmosphere.
