On November 5, 2024, scientists successfully launched the world's first wooden satellite, named Lignosat, from the United States to the International Space Station. Developed by Kyoto University and Sumitomo Forestry, Lignosat aims to explore the feasibility of constructing habitats on the Moon and Mars using wood.
The satellite, measuring just a few centimeters, will orbit the Earth at an altitude of 400 kilometers for six months. It is designed to gather data on the performance of wooden materials in the harsh conditions of space, particularly in relation to radiation effects on semiconductor components.
Lignosat's primary objective is to assess the viability of using wood for future space missions, with a goal set for 50 years from now. NASA has also expressed interest in standardizing wooden satellite technology. The satellite was constructed from Magnolia honoki, a type of wood found in Japan.
During its mission, Lignosat will transmit information back to Earth about how electronic devices function in space environments, particularly under extreme temperature fluctuations ranging from minus 100 to 100 degrees Celsius. The findings from this mission could be pivotal in determining the potential for using wood in space habitats.
Using wooden satellites offers environmental advantages, as they would burn up upon re-entry, leaving no debris. If Lignosat proves successful, it could lead to the development of wooden data centers in space, revolutionizing space exploration. According to Kenji Kariya from Sumitomo Forestry, advancements in the wood industry could significantly benefit from this innovative approach.
