The world’s first wood-panelled satellite tv for pc has been launched into house to check the suitability of wooden as a renewable constructing materials in future exploration of locations such because the moon and Mars.
The microsatellite, constructed by Japanese researchers and weighing solely 900 grams, will perform a SpaceX mission to the Worldwide House Station. It is going to then be launched into orbit above Earth.
Named LignoSat, after the Latin phrase for “wooden,” its panels are constructed from a sort of magnolia tree utilizing conventional methods that require no screws or glue.
The Kyoto College researchers who developed the fabric hope that sooner or later it might be doable to exchange a few of the metals utilized in house exploration with wooden.
“Wooden is extra sturdy in house than on Earth as a result of there isn’t any water or oxygen to permit it to rot or burn,” Kyoto College Forest Science Professor Koji Murata told Reuters information company.
“Airplanes within the early 1900s had been product of wooden,” Professor Murata mentioned. “Picket satellites also needs to be doable.”
Researchers hope that if bushes can at some point be grown on the moon or Mars, wooden may additionally present materials for future house colonies.
Along with its wood panels, LignoSat makes use of conventional aluminum development and digital parts. It’s outfitted with sensors to observe how its wooden reacts to the acute setting of house throughout its six months orbiting Earth.
Dr Simon Barber, an area analysis scientist on the Open College, mentioned: “We have now to be clear, this isn’t a satellite tv for pc made solely of wooden… however the primary premise behind the concept may be very attention-grabbing.
“From a sustainability perspective, wooden is a fabric that may be grown and subsequently renewable,” he informed the BBC.
“You would possibly be capable of develop wooden on one other planet that will help you discover house or construct shelters – explorers have all the time used wooden to construct shelters when touring to new lands.”
Dr Barber mentioned this was not the primary time wooden had been used on spacecraft.
“We use wood cork on the re-entry skins of spacecraft to assist them survive re-entry into the Earth’s environment.”
He added that Russian and Soviet lunar landers used corks to assist the rover grip because it descended to the lunar floor.
“There’s nothing mistaken with utilizing wooden in house – it’s utilizing the suitable materials for the suitable job.”
He factors out that wooden has properties which might be tough to regulate.
“So from an engineering perspective, it is a tough materials to work with… I believe wooden is all the time going to be an issue when making essential constructions, like spacecraft elements, the place it is advisable to predict how sturdy will probably be. ”
Researchers at Kyoto College hope that utilizing wooden to construct a spacecraft will produce far much less air pollution than a steel spacecraft when it burns up when reentering the environment on the finish of its life.
Consultants warn that as extra spacecraft and satellites are launched, the specter of house particles falling to Earth is rising.
Dr Barber acknowledged that the aerospace trade is beneath growing strain over the quantity of air pollution it pumps into the environment, however he expressed doubts that utilizing wood spacecraft would supply the reply.
“In precept, utilizing extra flammable supplies like wooden will surely scale back these steel contaminants… however you would possibly find yourself carrying extra materials with you simply to burn it off on the best way down.”
