Let it be said: even in space, it’s time to go green! With this in mind, the researchers launched a small wooden satellite Lignosate to the ISS to test its resistance to the extreme conditions of space. Goal: Paving the way for eco-friendly satellites! Unlike conventional metallic satellites, this material will burn cleanly upon re-entry into the atmosphere, without producing the usual pollutant particles.
The first satellite BoisBois Landed on a ship in the world The rocketThe rocket SpaceXSpaceXits Japanese designers announced today, as part of a resupply mission to the International Space Station (ISSISS). The experimental satellite, called LignoSat and shaped like a wooden cube only 10 centimeters on a side, was launched by an unmanned rocket from NASA’s Kennedy Space Center in Florida, Kyoto University’s Center for Space Studies said. Launched.
The purpose of the material is to anticipate its inevitable end to life: when it eventually returns and re-enters the atmosphere, it will produce the usual metallic particles associated with satellites, according to the Kyoto scientists. The wood should be burnt without doing. According to him, these particles can have negative effects on the environment but also on telecommunications.
Testing the strength and durability of wood in space
The wooden satellite is installed in a special container manufactured by Japan Aerospace Exploration Agency, Jaxa. Flew safely into space. », indicated the latter in a message on PortPort– A spokesman for LignoSat’s co-developer, Sumitomo Forestry, confirmed to AFP that the launch had been “successful”: the satellite will soon arrive at the ISS and will be sent into space in about a month to test its robustness and Its durability can be tested. said.
Data from the satellite will be sent to researchers, who can examine signs of deformation and determine whether it can withstand extreme temperature changes. ” Satellites that are not made of metal are expected to be more widespread. », estimated Takao Doi, astronaut and Kyoto University professor, during a press conference at the beginning of the year.
