ESA solar system insignia for the PROBA-2 mission
PROBA-2 is the second satellite in the European Space Agency's series of PROBA low-cost satellites that are being used to validate new spacecraft technologies while also carrying scientific instruments. PROBA-2 is a small satellite (130 kg) developed under an ESA General Support Technology Program (GSTP) contract by a Belgian consortium led by Verhaert (now QinetiQ Space) of Kruibeke, Belgium. The nominal mission duration was two years. As of 2019, the mission continues.
PROBA-2 contains five scientific instruments. Two of them are designated to observe the Sun: "The Sun Watcher using APS and Image Processing" (SWAP, an EUV imager) and the "Large Yield Radiometer" (LYRA), a radiometer made of diamond photodiodes. The Principal investigator teams of both instruments are hosted at the Royal Observatory of Belgium. This institute will also host the PROBA-2 Science Center from which the SWAP and LYRA instruments will be operated and their data distributed. There are three other instruments to measure basic space plasma properties: the Dual segmented Langmuir probe (DSLP) (developed by the Astronomical Institute and Institute of Atmospheric Physics, Academy of Sciences of the Czech Republic), the Thermal Plasma Measurement Unit (TPMU), and the Science Grade Vector Magnetometer (SGVM) developed by the Technical University of Denmark.
