* cheaper material
* naturally dampens vibrations -> can potentially help sensitive instruments
* naturally insulates heat better -> saves power on heating
* doesn't block radio frequencies -> lower drag in low orbits -> 50% longer orbital time
* fully burns up on re-entryhttps://metropolisjapan.com/why-wooden-architecture-is-makin...
