    Study Notes

    LignoSat: World's First Wooden Satellite

    • LignoSat, a palm-sized satellite made primarily of wood, was sent to the International Space Station (ISS) on November 5, 2024.
    • Its mission is to test the viability of wood in space and assess its resistance to harsh conditions.
    • Launch into Earth's orbit is planned later in December 2024.
    • LignoSat's design is based on magnolia wood.
    • Project developed by Kyoto University and Sumitomo Forestry

    Motivation Behind Wooden Satellite

    • Current satellites made of aluminum release aluminum oxide particles when they burn up, potentially harming the ozone layer.
    • Wooden satellites, burning into water and carbon dioxide, significantly reduce space debris.
    • Testing a wooden satellite addresses the growing space debris problem.
    • This could establish an eco-friendly practice of spacecraft design.

    Space Wood Project Background

    • A previous experiment involving a panel containing different wood samples was sent to the ISS in 2022.
    • The panel was exposed to space for ten months, leading to the selection of magnolia wood for LignoSat.
    • Researchers initially expected resistance in the application of wood as a material in spacecraft technology.

    Future Applications and Aims

    • LignoSat will orbit Earth for six months to collect data.
    • Researchers aim to use the data to develop larger wooden satellites and space technology.
    • Wood could be critical in future space colonization efforts through cultivation on the Moon and Mars.
    • Development shows wood's potential as a building material in space.
