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]
