Forward-looking: Researchers from Kyoto University in Japan have decided that wooden from magnolia bushes could possibly be the perfect building materials for a satellite resulting from launch into area next year.
Test outcomes from a latest experiment aboard the International Space Station amongst three wooden specimens revealed magnolia to be essentially the most versatile. The samples, which have been uncovered to the tough circumstances of area for 10 months, returned to Earth this previous January.
Analysis confirmed magnolia skilled no decomposition or injury like cracking, peeling, or warping. Furthermore, there was no change within the mass of the wooden samples earlier than and after their publicity in area.

Wood won’t look like your best option for a space-bound satellite, nevertheless it does have some distinctive benefit.
It is way simpler and cheaper to provide than metallic alloys historically used to construct satellites. What’s extra, wooden is extra environmentally pleasant, gentle weight, versatile, and would little question fritter away fully throughout reentry in Earth’s environment, minimizing the danger related to decommissioning a satellite. Existing satellites that are not anticipated to fritter away fully within the environment are introduced again to Earth over distant sections of the ocean.
A wooden satellite would not absolutely remove all dangers, nevertheless, as its inside parts would nonetheless be product of conventional supplies that may not fritter away as simply.

Kyoto University partnered with Sumitomo Forestry in 2020 on the LignoStella Space Wood Project, with the purpose of finally launching a wooden satellite into area. Simulated exams right here on Earth instructed wooden would possibly bode properly in area because it is ready to stand up to a big selection of temperatures and held up in near-vacuum circumstances.
According to Phys.org, the group’s wooden satellite will be launched collectively by NASA and the Japanese Aerospace Exploration Agency (JAXA) in 2024. An entry on Nanosats Database notes the satellite will carry out novice radio operations and assist educate college students in regards to the traits of the satellite.
