SIMBA (satellite)
SIMBA was a climatology satellite mission by the European Space Agency (ESA) in the form of a 3U CubeSat. 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. The satellite was launched in September 2020 aboard a Vega rocket and remained operational until December 2022. It deorbited in August 2024.
