Led by the Royal Meteorological Institute Belgium, Simba is a 3-unit CubeSat mission to measure the Total Solar Irradiance and Earth Radiation Budget climate variables with a miniaturised radiometer instrument, due to be launched in 2020 on the inaugural flight of the ESA's developed ‘Small Spacecraft Mission System’ dispenser – devoted to CubeSats and other small satellites – on a Vega launcher.
