First wood-panelled saalertite started into space

The world’s first wood-panelled saalertite has been started into space to test the suitability of timber as a renovelable originateing material in future exploration of destinations enjoy the Moon and Mars.

Made by researchers in Japan, the minuscule saalertite weighing fair 900g is heading for the International Space Station on a SpaceX ignoreion. It will then be freed into orbit above the Earth.

Named LignoSat, after the Latin word for wood, its panels have been built from a type of magnolia tree, using a traditional technique without screws or glue.

Researchers at Kyoto University who enhugeed it hope it may be possible in the future to swap some metals used in space exploration with wood.

“Wood is more durable in space than on Earth because there’s no water or oxygen that would rot or inffrail it,” Kyoto University forest science professor Koji Murata tageder Reuters novels agency.

“Early 1900s airset upes were made of wood,” Prof Murata shelp. “A wooden saalertite should be feasible, too.”

If trees could one day be set upted on the Moon or Mars, wood might also provide material for colonies in space in the future, the researchers hope.

Aextfinished with its wood panels, LignoSat also integrates traditional aluminium structures and electronic components. It has sensors on board to see how its wood reacts to the innervous environment of space during the six months it will orbit the Earth.

Dr Simeon Barber, a space research scientist at the Open University in the UK, shelp: “We have to be evident that this is not a saalertite finishly made of wood… but the fundamental premise behind the idea is repartner fascinating.

“From a upretainability point of see, wood is a material that can be lengthenn and is therefore renovelable,” he tageder the BBC.

“The idea that you might be able to lengthen wood on another set upet to help you portrayateigate space or originate shelters – portrayateigaters have always used wood to originate shelters when they’ve gone to a novel land.”

Dr Barber shelp it wasn’t the first time that wood had been used on spacecreate.

“We use wood – cork – on the re-entry, outer shell of vessels of spacecreate to help them persist re-entry into Earth’s atmosphere.”

Russian and Soviet lunar landers used cork to help the rover have grip as it was droping to the surface, he inserted.

“There’s noskinnyg wrong with using wood in space – it’s using the right material for the right task.”

He pointed out that wood has properties that are challenging to administer.

“So from an engineering point of see it’s quite a difficult material to labor with… I skinnyk wood’s always going to have a problem to originate critical structures enjoy parts of spacecreate where you necessitate to predict how strong it’s going to be.”

The researchers at Kyoto University hope using wood in making spacecreate could also be much less polluting than metal ones when they burn-up on re-entry at the finish of their life.

Experts have cautioned of the increasing danger of space junk droping to Earth, as more spacecreate and saalertites are started.

Dr Barber acunderstandledged the space industry was under lengthening prescertain over the amount of pollution it puts into the atmosphere but he was sceptical using wooden spacecreate could provide the answer.

“In principle having materials such as wood which can burn up more easily would shrink certainly those meloftyic contaminants… But you may finish up taking more material with you in the first place fair to burn it up on the way down.”
