First wood-panelled satellite launched into space

The world’s first wood-panelled satellite tv for pc has been launched into area to check the suitability of timber as a renewable constructing materials in future exploration of locations just like the Moon and Mars.

Made by researchers in Japan, the tiny satellite tv for pc weighing simply 900g is heading for the Worldwide Area Station on a SpaceX mission. It would then be launched into orbit above the Earth.

Named LignoSat, after the Latin phrase for wooden, its panels have been constructed from a sort of magnolia tree, utilizing a standard method with out screws or glue.

Researchers at Kyoto College who developed it hope it could be potential sooner or later to exchange some metals utilized in area exploration with wooden.

“Wooden is extra sturdy in area than on Earth as a result of there is not any water or oxygen that may rot or inflame it,” Kyoto College forest science professor Koji Murata told Reuters information company.

“Early 1900s airplanes had been manufactured from wooden,” Prof Murata mentioned. “A picket satellite tv for pc needs to be possible, too.”

If bushes may in the future be planted on the Moon or Mars, wooden may additionally present materials for colonies in area sooner or later, the researchers hope.

Together with its wooden panels, LignoSat additionally incorporates conventional aluminium constructions and digital elements. It has sensors on board to observe how its wooden reacts to the intense setting of area in the course of the six months it’ll orbit the Earth.

Dr Simeon Barber, an area analysis scientist on the Open College within the UK, mentioned: “We’ve got to be clear that this isn’t a satellite tv for pc utterly manufactured from wooden… however the fundamental premise behind the concept is actually fascinating.

“From a sustainability standpoint, wooden is a cloth that may be grown and is subsequently renewable,” he informed the BBC.

“The concept you may be capable to develop wooden on one other planet that can assist you discover area or make shelters – explorers have all the time used wooden to make shelters once they’ve gone to a brand new land.”

Dr Barber mentioned it wasn’t the primary time that wooden had been used on spacecraft.

“We use wooden – cork – on the re-entry, outer shell of vessels of spacecraft to assist them survive re-entry into Earth’s ambiance.”

Russian and Soviet lunar landers used cork to assist the rover have grip because it was descending to the floor, he added.

“There’s nothing incorrect with utilizing wooden in area – it is utilizing the suitable materials for the suitable activity.”

He identified that wooden has properties which might be exhausting to regulate.

“So from an engineering standpoint it is fairly a troublesome materials to work with… I feel wooden’s all the time going to have an issue to make crucial constructions like elements of spacecraft the place it’s essential to predict how sturdy it may be.”

The researchers at Kyoto College hope utilizing wooden in making spacecraft is also a lot much less polluting than steel ones once they burn-up on re-entry on the finish of their life.

Specialists have warned of the rising menace of area junk falling to Earth, as extra spacecraft and satellites are launched.

Dr Barber acknowledged the area trade was beneath rising stress over the quantity of air pollution it places into the ambiance however he was sceptical utilizing picket spacecraft may present the reply.

“In precept having supplies corresponding to wooden which might dissipate extra simply would cut back actually these metallic contaminants… However it’s possible you’ll find yourself taking extra materials with you within the first place simply to burn it up on the best way down.”
