LignoSat

Current Context : The world’s first wooden satellite, developed by Japan, has been launched.

The satellite will study how wood withstands space’s extreme conditions.

About Lignosat :

• It is jointly created by Kyoto University and Sumitomo Forestry, it represents eco-friendly satellite technology.
• Constructed from honoki wood (magnolia species) for its strength and workability; includes some aluminum and electronic components​

Key Features:

• Compact size : palm-sized cube (about 10 cm per side).
• Power sourced from solar panels.​

Purpose and Significance:

• To test wood’s durability in space’s extreme conditions like temperature shifts and radiation.​
• Aims to reduce space debris; wooden satellites burn up completely on re-entry, unlike metal satellites that release harmful particles.​

Advantages:

• Wood is resistant to decay due to the absence of water and oxygen in space.
• Antennas can be embedded within wood, reducing failure risks.​
