A Japanese company and Kyoto University have signed up with forces to develop what they hope will be the world’s first satellites constructed out of wood by 2023.
Sumitomo Forestry said it has actually started research on tree growth and making use of wood materials in space.
The collaboration will begin try out different types of wood in severe environments on Earth.
Space junk is becoming an increasing problem as more satellites are launched into the atmosphere.
Wooden satellites would burn up without releasing damaging compounds into the atmosphere or raining debris on the ground when they plunge back to Earth.
” We are really worried about the reality that all the satellites which return to the Earth’s atmosphere burn and create tiny alumina particles which will drift in the upper atmosphere for several years,” Takao Doi, a teacher at Kyoto University and Japanese astronaut, informed the BBC.
” Ultimately it will affect the environment of the Earth.”
“The next phase will be establishing the engineering design of the satellite, then we will make the flight design,” Professor Doi added.
As an astronaut he visited the International Space Station in March 2008.
During this mission, he ended up being the first individual to throw a boomerang in space that had actually been particularly developed for use in microgravity.
Sumitomo Forestry, part of the Sumitomo Group, which was founded more than 400 years ago, said it would work on establishing wood products highly resistant to temperature changes and sunlight.
The wood it is utilizing is an “R&D secret” a spokesperson for the company told the BBC.
Professionals have cautioned of the increasing hazard of space junk being up to Earth, as more spacecraft and satellites are launched.
Satellites are significantly being used for interaction, television, navigation and weather forecasting. Space specialists and scientists have actually been investigating various choices to get rid of and reduce the space junk.
There are almost 6,000 satellites circling around Earth, according to the World Economic Online Forum (WEF). About 60% of them are defunct (space scrap).
Research study company Euroconsult estimates that 990 satellites will be released every year this years, which means that by 2028, there might be 15,000 satellites in orbit.
Elon Musk’s SpaceX has actually already launched more than 900 Starlink satellites and has strategies to release thousands more.
Area scrap travels at an incredibly fast speed of more than 22,300 mph, so can have cause considerable damage to any things it strikes.
In 2006 a tiny piece of space scrap collided with the International Space Station, taking a chip out of the greatly reinforced window.
