Forward-looking: Researchers from Kyoto University in Japan have decided that wooden from magnolia bushes may very well be the best building materials for a satellite tv for pc resulting from launch into house subsequent yr.
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 had been uncovered to the cruel circumstances of house 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 house.
Wood may not seem to be your best option for a space-bound satellite tv for pc, but it surely 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 doubt expend utterly throughout reentry in Earth’s ambiance, minimizing the chance related to decommissioning a satellite tv for pc. Existing satellites that are not anticipated to expend utterly within the ambiance are introduced again to Earth over distant sections of the ocean.
A wooden satellite tv for pc would not totally remove all dangers, nonetheless, as its inside elements would nonetheless be made from conventional supplies which may not expend as simply.

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