Researchers from Japan believe that timber is a space-grade material that could on day be used to build houses on Mars. Their satellite was crafted from honoki wood without screws or glue to hold it together.
Summary
Japan launched the world’s first wooden satellite, LignoSat, to test if wood can function as a space-grade material. Developed by Kyoto University, the satellite is made of honoki wood, chosen after a 10-month ISS experiment proved its suitability for space.
Designed without screws or glue, LignoSat will orbit Earth for six months, enduring extreme temperature swings and measuring wood’s resistance to space radiation. Advocates highlight wood’s eco-friendly re-entry properties compared to metal.
Researchers envision wooden structures for future space habitats, potentially boosting the timber industry.
Edit well I'd never heard of honoki wood! Learn something new every day. Honoki (朴の木, hou wood, Japanese Bigleaf Magnolia, Magnolia obavata-hinoki wood, from Chamaecyparis obtusa.
I'm guessing they freeze-dried it already, so not that much.
If they didn't, it will freeze-dry itself. I have no clue what that would do to the dimensions, since it's not going to be a controlled process like it would be on Earth,
It will measure how wood endures the extreme environment of space, where temperatures fluctuate from -100 to 100 degrees Celsius (-148 to 212 degrees Fahrenheit) every 45 minutes as objects orbit through darkness and sunlight.
I've never heard of anyone freeze-drying an instrument. Space doesn't freeze things, that requires somewhere for the heat to go. That's an interesting idea though.
Maybe it won't expand and contract for the same reasons. After all, there isn't any moisture in space.
