The CSIRO Laboratory for Satellite Optics opened in 2018, and built the optical payload for the upcoming CSIROSat-1 cubesat mission – a shortwave infrared hyperspectral imager with a variety of science cases from studies of cyclones to mineral deposits. Since then, the Optical Systems Team, a part of CSIRO Manufacturing, has built customised hyperspectral imagers using novel metal 3d printing, custom manufactured optics and filters, and radiation tolerant electronic hardware. They have undergone lab testing, drone flights, and recently a balloon flight that captured hyperspectral imagery from 35 km altitude above rural Victoria. The team is currently building the payload for CyanoSat, a satellite specifically designed to recognise harmful algal blooms from space
