The world’s first wooden satellite is on the way, in the shape of the Finnish WISA Woodsat. European Space Agency (ESA) materials experts are contributing a suite of experimental sensors to the mission as well as helping with pre-flight testing. WISA Woodsat is a 10x10x10 cm ‘CubeSat’ – a type of nano-satellite built up from standardized boxes – but with surface panels made from plywood. Woodsat’s only non-wooden external parts are corner aluminum rails used for its deployment into space plus a metal selfie stick. Woodsat has secured a berth on a Rocket Lab Electron rocket to be launched from New Zealand before the end of this year.
