 Japanese companies and Kyoto University have teamed up to develop what they hope will be the world's first wooden satellite by 2023.Sumitomo Forestry said it has begun research into tree growth and the use of wood materials in space.The collaboration will begin experimenting with different types of wood in the harsh environment on Earth.Space debris is becoming a growing problem as more satellites are launched into the atmosphere.The wooden satellites will catch fire without releasing harmful substances into the atmosphere or raining debris on the ground as they fly back to Earth.We are very concerned with the fact that all satellites that return to Earth's atmosphere will burn and generate tiny alumina particles that will remain in the upper atmosphere for years, according to the.
It will eventually affect the global environment"The slotxo next step is to develop a satellite engineering model, and then we will produce a flight model," added Professor Doi.As an astronaut, he visited the International Space Station in March 2008.During this mission, he became the first to throw a boomerang into space, designed specifically for use in microgravity.Sumitomo Forestry, part of the Sumitomo Group, which has been established for more than 400 years, says it will develop wood materials that are resistant to temperature changes and sunlight.Wood used as "Secrets of research and development," a company spokesperson.
Space junk
Experts warn of the growing threat of space junk falling to Earth as more spacecraft and satellites are launched.Satellites are increasingly being used for communication, television, navigation and weather forecasting. Space experts and researchers are investigating options for removing and reducing space debris.There are almost 6,000 satellites orbiting the Earth, according to the World Economic Forum (WEF) .About 60% of them have died (space junk).Research firm Euroconsult predicts that 990 satellites will be launched every year this decade, meaning that by 2028 there could be 15,000 satellites in orbit.Elon Musk's SpaceX has launched more than 900 Starlink satellites, and thousands more are planned to be installed.Space junk travels at an incredibly fast speed of over 22,300 miles per hour, so it can cause massive damage to any object it collides with.In 2006, a tiny piece of space junk collided with the International Space Station, taking the chip out of a reinforced window.
