In a groundbreaking development, the Japan Aerospace Exploration Agency (JAXA), Kyoto University, and NASA have selected magnolia wood as the material for the construction of LignoSat, the first ecological satellite in history. After extensive testing on the International Space Station, magnolia proved to be the most resilient wood, able to withstand intense cosmic rays, temperature changes, and solar particles without deforming or deteriorating.
The LignoSat, which will be the size of a large orange, is set to be launched into orbit this summer. Its construction aims to be biodegradable, durable, lightweight, and more cost-effective than traditional satellites. The scientific mission of LignoSat will focus on measuring the behavior of wood in space under various conditions, with the ultimate goal of designing more resilient and sustainable devices.
One of the key advantages of LignoSat is its environmental impact. Unlike conventional satellites that release toxic aluminum particles into the atmosphere upon re-entry, LignoSat’s body will only turn into ash, minimizing environmental risks. This is particularly important as the space industry faces challenges with the increasing amount of space debris, posing a threat to future missions and satellite operations.
Commercial satellites, which operate at higher altitudes above the Earth, often become hazardous space debris once they reach the end of their useful life. The use of magnolia wood in LignoSat represents a significant step towards reducing the environmental impact of space exploration and promoting sustainability in the aerospace industry.
The launch of LignoSat marks a significant milestone in space technology and environmental conservation, paving the way for a more sustainable approach to satellite construction and operation.
