Japan launches LignoSat, a game-changing wooden satellite, to investigate wood's potential in space applications, reducing space debris and environmental harm.

Japan made history on November 5, launching the world's first wooden satellite, LignoSat, into space. This innovative project, developed by Kyoto University and Sumitomo Forestry, aims to explore wood's potential in lunar and Mars missions.

LignoSat, named after the Latin word for “wood,” was aboard a SpaceX flight to the International Space Station. From there, it will be deployed into orbit approximately 400 km (250 miles) above Earth. This initial test will assess wood's durability and performance in space.

The LignoSat mission seeks to revolutionize space exploration by utilizing wood, a renewable and sustainable material. Researchers will monitor the satellite's performance, focusing on wood's resistance to radiation, extreme temperatures, and space debris.

By testing wood in space, scientists hope to pave the way for eco-friendly habitats in future lunar and Mars missions. LignoSat's success could significantly impact the development of sustainable space exploration technologies.

Japan's ambitious 50-year plan to establish lunar and Martian settlements took its first step with the launch of the world's first wooden satellite. This innovative project, led by astronaut Takao Doi, aims to demonstrate wood's viability in space.

“With timber, a material we can produce by ourselves, we will be able to build houses, live and work in space forever,” says Takao Doi, a seasoned astronaut who has flown on the Space Shuttle and currently studies human space activities at Kyoto University.

Doi's team chose to create a NASA-certified wooden satellite to test wood's durability and performance in space. This experiment paves the way for the long-term goal of planting trees and constructing wooden houses on the Moon and Mars, enabling sustainable human presence in space.

The wooden satellite's success marks a crucial milestone in Japan's quest for self-sufficiency in space exploration and habitation. By leveraging locally sourced materials, Japan aims to reduce reliance on external resources and create a thriving space-based community.

Doi's vision extends beyond the satellite, envisioning a future where wood plays a central role in space architecture. As researchers gather data from the satellite, they will refine their designs for lunar and Martian settlements, bringing humanity closer to permanent residence in space.

“Early 1900s airplanes were made of wood.

”Wooden satellite should be feasible, too,” Koji Murata a professor of Forest science at the Kyoto University, Japan, said.

Adding that, “Wood is more durable in space than on Earth because there's no water or oxygen that would rot or inflame it.”

Wooden satellites offer a sustainable solution for space exploration, reducing environmental harm at the end of their life cycle.

Unlike metal satellites, which release toxic aluminum oxide particles during re-entry, wooden satellites burn up cleanly, minimizing pollution.

This eco-friendly design tackles the pressing issue of space debris, promoting responsible space practices.

By using natural materials, researchers aim to reduce the environmental footprint of satellite missions, paving the way for greener space technologies.

“Metal satellites might be banned in the future.

“If we can prove our first wooden satellite works, we want to pitch it to Elon Musk's SpaceX,” Doi further stated.

After a comprehensive 10-month experiment on the International Space Station, researchers identified honoki, a native Japanese magnolia tree, as the ideal wood for spacecraft construction. Traditionally used for crafting sword sheaths, honoki's unique properties make it an excellent choice for space exploration.

LignoSat, the pioneering wooden satellite, is crafted from honoki using ancient Japanese techniques, eliminating the need for screws or glue. This innovative approach ensures a seamless, robust structure capable of withstanding the harsh conditions of space.

During its six-month orbit, LignoSat's onboard electronics will monitor the wood's performance, exposing it to extreme temperatures fluctuating between -100°C and 100°C every 45 minutes as it transitions from darkness to sunlight.

Beyond assessing wood's durability, LignoSat will also investigate its potential as a natural radiation shield for semiconductors, according to Kenji Kariya, manager at Sumitomo Forestry's Tsukuba Research Institute. This breakthrough could have significant implications for data center construction and other applications.

Key findings from LignoSat's mission will inform the development of sustainable, eco-friendly spacecraft and habitats, paving the way for future lunar and Mars missions.

“It may seem outdated, but wood is actually cutting-edge technology as civilisation heads to the moon and Mars.

“Expansion to space could invigorate the timber industry,” He said.
