An international project led by Kyoto University tested and confirmed the high durability of space wood at the International Space Station—the ISS. The experiment results showed minimal deterioration and good stability of the samples selected for the wooden artificial satellite LignoSat.
The research group conducted a preliminary inspection involving strength tests and elemental and crystal structural analyses of the wood samples, retrieved from space by Astronaut Koichi Wakata and returned to Earth from the ISS on SpaceX CRS-26—a Commercial Resupply Service mission.
Despite the extreme environment of outer space involving significant temperature changes and exposure to intense cosmic rays and dangerous solar particles for ten months, tests confirmed no decomposition or deformations, such as cracking, warping, peeling, or surface damage.
Three wood specimens were tested and showed no deformation after space exposure. The experiment results also confirmed no mass change in each wood specimen before and after space exposure.
