The world’s first wooden satellite is on the way, in the shape of the Finnish WISA Woodsat. 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 nanosatellite built up from standardised boxes – but with surface panels made from plywood. Woodsat’s only non-wooden external parts are corner aluminium rails used for its deployment into space plus a metal selfie stick.
ESA materials engineers are embarking a pressure sensor, a test of electrically conductive plastic and a quartz crystal microbalance, all housed on the same printed circuit board, plus a test of shape memory alloy.
