GREEN LIFE – Wooden satellites to reduce space junk


A #Japanese company and the #University of #Kyoto have joined forces to develop the world’s first satellites made of wood by 2023 with the goal of reducing space debris.

#Sumitomo #Forestry said it has started researching tree growth and the use of wood materials in space.

The association will begin to experiment with different types of wood in extreme environments on #Earth.

#Space debris is becoming a growing problem as more satellites are launched into the atmosphere. The wooden satellites would burn without releasing harmful substances into the atmosphere or raining debris onto the ground when they return to #Earth.

“#We are very concerned about the fact that all satellites that re-enter the #Earth’s atmosphere burn out and create small alumina particles that will float in the upper atmosphere for many years,” #Takao #Doi, professor of #Kyoto #University and #Japanese astronaut.

“The next stage of the project will be to develop the engineering model of the satellite, then we will manufacture the flight model,” added #Professor #Doi, who as an astronaut visited the #International #Space #Station in #March 2008. #During this mission he became the first person in launching a boomerang into space that had been specifically designed for use in microgravity.

#Secreto de I + D

#Sumitomo #Forestry, part of the #Sumitomo #Group, which was founded more than 400 years ago, said it would work on developing wood materials highly resistant to changes in temperature and sunlight. The wood it uses is an “R&D secret,” a company spokesperson told the BBC.

#Experts have warned of the growing threat of space debris falling to #Earth, as more spacecraft and satellites are launched.

#Satellites are increasingly used for communications, television, navigation and weather forecasting. #Space experts and researchers have been investigating different options to eliminate and reduce space debris.

There are nearly 6,000 satellites circling the #Earth, according to the #World #Economic #Forum (WEF). #About 60% of them have stopped working and are considered space junk.
#Research firm #Euroconsult estimates that 990 satellites will be launched each year this decade, which means that by 2028 there could be 15,000 satellites in orbit.

OF INTEREST

#Threat. #Space debris travels at a speed of 35,000 kilometers per hour, so it can cause considerable damage to any object it hits.
