KYOTO (Reuters): The world’s first wooden satellite, built by Japanese researchers, was launched into space on Tuesday, in an early test of using timber in lunar and Mars exploration.<\/span><\/p>\n

LignoSat, developed by Kyoto University and homebuilder Sumitomo Forestry (1911.T), opens a\u00a0<\/span>new<\/span> tab, will be flown to the International Space Station on a SpaceX mission, and later released into orbit about 400 km (250 miles) above the Earth.<\/span><\/p>\n

Named after the Latin word for “wood”, the palm-sized LignoSat is tasked to demonstrate the cosmic potential of the renewable material as humans explore\u00a0living in space.<\/span><\/p>\n

“With timber, a material we can produce by ourselves, we will be able to build houses, live and work in space forever,” said Takao Doi, an astronaut who has flown on the Space Shuttle and studies human space activities at Kyoto University.<\/span><\/p>\n

With a 50-year plan of planting trees and building timber houses on the moon and Mars, Doi’s team decided to develop a NASA-certified wooden satellite to prove wood is a space-grade material.<\/span><\/p>\n

“Early 1900s airplanes were made of wood,” said Kyoto University forest science professor Koji Murata. “A wooden satellite should be feasible, too.”<\/span><\/p>\n

Wood is more durable in space than on Earth because <\/span>there’s no water or oxygen that would<\/span> rot or inflame it, Murata added.<\/span><\/p>\n

A wooden satellite also <\/span>minimises<\/span> the environmental impact at the end of its life, the researchers say.<\/span><\/p>\n

Decommissioned satellites must re-enter the atmosphere to avoid becoming\u00a0space debris. Conventional metal satellites create <\/span>aluminum<\/span> oxide particles during re-entry, but wooden ones would just burn up with less pollution, Doi said.<\/span><\/p>\n

“Metal satellites might be banned in the future,” Doi said. “If we can prove our first wooden satellite works, we want to pitch it to Elon Musk’s SpaceX.”<\/span><\/p>\n

Industrial application<\/span><\/h2>\n

The researchers found that honoki, a kind of magnolia tree native <\/span>to<\/span> Japan and traditionally used for sword sheaths, is most suited for spacecraft, after a 10-month experiment aboard the International Space Station.<\/span><\/p>\n

LignoSat is made of <\/span>honoki<\/span>, using a traditional Japanese crafts technique without screws or glue.<\/span><\/p>\n

Once deployed, LignoSat will stay in <\/span>orbit<\/span> for six months, with the electronic components onboard measuring how wood endures the\u00a0extreme environment\u00a0of space, where temperatures fluctuate from -100 to 100 degrees Celsius every 45 minutes as it orbits from darkness to sunlight.<\/span><\/p>\n

LignoSat will also gauge wood’s ability to reduce the impact of space radiation on semiconductors, making it useful for applications such as\u00a0data <\/span>centre<\/span> construction, said Kenji Kariya, a manager at Sumitomo Forestry Tsukuba Research Institute.<\/span><\/p>\n

“It may seem outdated, but wood is <\/span>actually<\/span> cutting-edge technology as <\/span>civilisation<\/span> heads to the moon and Mars,” he said. “Expansion to space could invigorate the timber industry.”<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
