Wood, unlike traditional materials, does not burn or rot in the vacuum of space. However, upon reentry into Earth's atmosphere, it will incinerate into a fine ash, presenting a novel and environmentally friendly solution to the growing issue of space debris. The decision to use magnolia wood was based on successful tests conducted on three different wood specimens, including magnolia, cherry, and birch, aboard the International Space Station (ISS). These tests revealed no deformation, cracking, warping, peeling, or surface damage, even after exposure to the harsh conditions of outer space for ten months.
The current proliferation of space objects, totaling over 9,300 tons, contributes to the growing challenge of space debris, including defunct satellites and remnants of spent rocket stages. Traditional spacecraft made from metals like titanium and aluminum not only add to this debris but also contribute to light pollution, making it harder to observe distant space phenomena. In contrast, wooden satellites, such as LignoSat, are expected to offer a more environmentally friendly and less hazardous alternative as they burn up upon reentry.
The development of LignoSat represents a collaborative effort to address the environmental impact of space exploration, offering a promising solution to reduce space debris and minimize the ecological footprint of satellite missions.
