The first-ever wooden artificial satellite built by Japanese researchers was recently launched into space. The project aims to use wood as a solution for sustainable space exploration, as humanity produces more and more space debris to fulfill its missions to other worlds.
The satellite, named after the Latin word applesat, meaning “tree,” flew from NASA’s Kennedy Space Center in Florida to the International Space Station (ISS) on an unmanned SpaceX rocket.
It measures just 4 inches on each side and is made primarily from Magnolia magnolia, a type of magnolia native to Japan.
Traditional Japanese woodworking techniques are utilized. No glue or screws were used in the construction of this satellite.
The creation of the world’s first wooden satellite was inspired by critical environmental concerns. Harmful metal particles from deorbited satellites continue to accumulate in Earth’s upper atmosphere.
To avoid becoming space junk, decommissioned satellites must re-enter the atmosphere. However, conventional metal satellites produce aluminum oxide particles upon reentry, posing significant environmental risks.
“The re-entry of the spacecraft is changing the upper atmosphere,” said Aaron Boley, an associate professor of astronomy and astrophysics at the University of British Columbia.
“As humanity continues to access, explore and use space, this is a challenge that must be addressed.”
In comparison, wooden satellites simply burn up at the end of their lifespan, resulting in less pollution. Wood performs well in space because there is no water or oxygen that can cause it to rot or become irritated.
