SIMBA (Sun-earth IMBAlance) was a climatology satellite mission by the European Space Agency (ESA) in the form of a 3U CubeSat.[1][2][3] Its goal was to help quantify how much heat from the Sun is being retained within Earth atmosphere. For this, SIMBA measured Earth's radiation budget and total solar irradiance using a miniaturized radiometer instrument.[4][5] The satellite was launched in September 2020 aboard a Vega rocket and remained operational until December 2022.[6][7][8][9] It deorbited in August 2024.[10][11][12]
