Study Notes
Lignosat, the World's First Wooden Satellite
- Lignosat is being developed by a team from Kyoto University and homebuilder Sumitomo forestry
- The satellite is scheduled for launch next week on a SpaceX rocket
- Once in orbit, Lignosat will be released from the International Space Station and orbit for 6 months
- The satellite is named after the Latin word for wood, "Lignum"
- Objective: To test the viability of wood as a material for use in space.
Wood: A Sustainable Option for Space Exploration
- Professor Koji Morita, a forest science professor, believes wood can perform well in space due to its resistance to rot and fire
- The wood used for the satellite is from a type of magnolia tree, Japanese Hanoki
- The wood is easy to process, resistant to shattering, and traditionally used for making swords and sandal blades
- Wood offers an advantage at the end of the satellite's life as it burns up harmlessly in the Earth's atmosphere, unlike traditional satellites that release polluting metal particles.
A Vision for the Future of Space Exploration
- Former astronaut Taka Doi envisions building timber houses on the Moon and Mars
- This vision involves planting trees and building structures using sustainable materials
