The ESA is organised as an international governmental organisation in which not only most Member States of the EU participate but also the United Kingdom, Switzerland, and Canada. ESA is separate from but cooperates with the EU. Their tasks include space exploration and satellites, involving large value and high-technology procurement. An aggrieved bidder can launch an appeal against a procurement award decision of ESA at the ESA Procurement Review Board after unsuccessful complaints first to the Head of the Agency's Procurement Department and then to the Industrial Ombudsman of ESA. The now six Members of the Board sit at the ESA headquarters in Paris. ESA also has important sites in Noordwijk (The Netherlands), Darmstadt (Germany), Torrejon (Spain), and Kourou (French Guyana).
