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.[3] 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.[1] As of 2022, the mission continues.[4]

Mission summary

It was launched on 2 November 2009, with the Rockot launch system together with ESA's SMOS mission.[5] The platform was launched in a sun-synchronous low Earth orbit (altitude of 725 km).[1]

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)[1] (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.[1]

Proba-2 ist ein Kleinsatellit der ESA, der entsprechend dem Konzept von Proba-1 (engl. Project for On-Board Autonomy für Projekt für Bordautonomie) autonom und kostengünstig operieren soll. Der Start des 130 kg schweren und 0,6×0,6×0,8 Meter großen boxförmigen Satelliten auf eine sonnensynchrone Umlaufbahn in 700 km Höhe erfolgte am 2. November 2009[2] zusammen mit dem SMOS-Satelliten an Bord einer Rockot-Rakete vom russischen Weltraumbahnhof Plessezk aus. Die Mission verbindet Technologietests mit dem Betrieb als wissenschaftliche Sonnenbeobachtungsplattform. Proba-2 untersucht dabei die Sonnenstrahlung und das vom Sonnenwind erzeugte Plasma in der Magnetosphäre der Erde. Außen angebrachte Laserreflektoren ermöglichen die genaue Positionsbestimmung von der Erde aus. Die Kontrolle erfolgt durch ESEC in Redu, Belgien.
