The world’s first wood satellite tv for pc, constructed by Japanese researchers, was launched into area on Tuesday, in an early take a look at of utilizing timber in lunar and Mars exploration.
LignoSat, developed by Kyoto College and homebuilder Sumitomo Forestry, shall be flown to the Worldwide Area Station on a SpaceX mission, and later launched into orbit about 400km above Earth.
Named after the Latin phrase for “wooden”, the palm-sized LignoSat is tasked to exhibit the cosmic potential of the renewable materials as people discover dwelling in area.
“With timber, a cloth we are able to produce by ourselves, we will construct homes, reside and work in area without end,” mentioned Takao Doi, an astronaut who has flown on the Area Shuttle and research human area actions at Kyoto College.
With a 50-year plan of planting timber and constructing timber homes on the moon and Mars, Doi’s workforce determined to develop a Nasa-certified wood satellite tv for pc to show wooden is a space-grade materials.
“Early 1900s airplanes had been made from wooden,” mentioned Kyoto College forest science professor Koji Murata. “A wood satellite tv for pc needs to be possible, too.”
Wooden is extra sturdy in area than on Earth as a result of there’s no water or oxygen that may rot or inflame it, Murata added. A wood satellite tv for pc additionally minimises the environmental influence on the finish of its life, the researchers say.
Pitch to Musk
Decommissioned satellites should re-enter the ambiance to keep away from changing into area particles. Typical metallic satellites create aluminium oxide particles throughout re-entry, however wood ones would simply fritter away with much less air pollution, Doi mentioned.
“Steel satellites may be banned sooner or later,” Doi mentioned. “If we are able to show our first wood satellite tv for pc works, we need to pitch it to Elon Musk’s SpaceX.”

The researchers discovered that honoki, a sort of magnolia tree native in Japan and historically used for sword sheaths, is most suited to spacecraft, after a 10-month experiment aboard the Worldwide Area Station. LignoSat is made from honoki, utilizing a standard Japanese crafts approach with out screws or glue.
As soon as deployed, LignoSat will keep within the orbit for six months, with the digital parts onboard measuring how wooden endures the intense surroundings of area, the place temperatures fluctuate from -100ºC to 100ºC each 45 minutes because it orbits from darkness to daylight.
LignoSat can even gauge wooden’s capability to scale back the influence of area radiation on semiconductors, making it helpful for purposes similar to information centre development, mentioned Kenji Kariya, a supervisor at Sumitomo Forestry Tsukuba Analysis Institute.
“It could appear outdated, however wooden is definitely cutting-edge expertise as civilisation heads to the moon and Mars,” he mentioned. “Enlargement to area may invigorate the timber business.” — Kantaro Komiya and Irene Wang, (c) 2024 Reuters
