One of ESA’s upcoming CubeSat missions, Sun-Earth IMBAlance (SIMBA), is currently being assembled in a laboratory clean room on ESA’s site in Noordwijk, Netherlands.
Led by the Royal Meteorological Institute Belgium and supported by GSTP’s FLY element, SIMBA is a 3-unit CubeSat mission to measure the Total Solar Irradiance and Earth Radiation Budget climate variables with a miniaturised radiometer instrument.
Alongside the ozone-measuring Picasso and PhiSat CubeSats, Simba is investigating the application of artificial intelligence to Earth observation and whether or not the same instrument can measure both the Sun’s incoming radiation to Earth, and Earth’s own outgoing radiation.
