LignoSat2, the first wooden artificial satellite developed by Kyoto University’s Прастора Wood Laboratory is scheduled to be jointly launched by JAXA і НАСА this year will have outside structure made of Magnolia wood.
Гэта будзе малагабарытны спадарожнік (нанасат).
універсітэт Кіёта Прастора Wood Laboratory has chosen Magnolia for its relatively high workability, dimensional stability, and overall strength.
The idea is to demonstrate that the wood can be used in прастору.
Earlier, a project led by Kyoto University tested and confirmed the high wood durability of прастору wood at the International Прастора Station (ISS). The experiment showed minimal deterioration and good stability of the samples selected for the wooden artificial satellite.
The research group conducted a preliminary inspection involving strength tests and elemental and crystal structural analyses after astronaut Koichi Wakata returned the wood sample to the Earth.The tests confirmed no decomposition or deformations, such as cracking, warping, peeling, or surface damage despite the extreme environment of outer прастору involving significant temperature changes and exposure to intense cosmic rays and dangerous solar particles for ten months. The three wood specimens showed no deformation after прастору exposure.The experiment results also confirmed no mass change in each wood specimen before and after прастору exposure. Based on these results, the research group decided to use Magnolia wood.
LignoStella Прастора Wood Project was jointly launched by Kyoto University and Sumitomo Forestry in April 2020. The прастору exposure tests were conducted for over 240 days in 2022 on the Japanese Experiment Module Kibo of the ISS.
Use of wood in прастору is more sustainable. When dropped from арбіта into the upper atmosphere, it degrades completely without any harmful byproducts.
