50 years of ESA (1975 – 2025): the organization

The European Space Agency (ESA) is engaged in projects within a European context in the fields of spaceflight, Earth exploration, space research, the development of satellite-based technologies, and the promotion of the European economy. ESA works closely with the European Union but is not formally part of it. ESA was founded on May 30, 1975, so 50 years ago.

ESA organization

Founding

ESA was formed in 1975 from the European Space Research Organisation (ESRO) and the European Launcher Development Organisation (ELDO). The ESRO initially supplied rockets and satellites for participating countries and had its first launches on 6 and 9 July 1964.  

Member States

ESA now has twenty-two member states: Belgium, Denmark, Germany, Estonia, Finland, France, Greece, Hungary, Ireland, Italy, Luxembourg, the Netherlands, Norway, Austria, Poland, Portugal, Romania, Spain, the Czech Republic, the United Kingdom, Sweden and SwitzerlandTherefore, there are countries that are members of ESA but not of the European Union, and vice versa. Consequently, ESA cannot be considered a space agency of the European Union. In addition to these full members, ESA also has a cooperation agreement with SloveniaSlovakia, Latvia, Lithuania, and Bulgaria; as a result, these countries acquire the status of European Cooperative State (ECS). ESA also has another type of partnership with TurkeyUkraine, Cyprus, Israel, and Malta; these countries have signed a so-called “Cooperation Agreement”. ESA also cooperates with other (non-European) countries, for example with Canada for certain projects.  

Organisation

The central governing body of ESA is the Council. The Council determines the general guidelines on the basis of which ESA shapes its space policy. Every Member State is represented on the Council and has a vote, regardless of its size or financial contribution.   ESA does not develop and build satellites itself, but defines a detailed set of requirements and subsequently acts as the client, based on which the industries of the countries that are members of ESA undertake development and construction. ESA also has a technical center in Noordwijk, the European Space Research and Technology Centre (ESTEC), in which satellites can be tested during their construction and testing phases to verify whether the set requirements are met. ESA focuses solely on civilian projects.  

Locations

ESA's headquarters are located in Paris, where the most important decisions regarding future projects are also made. The other ESA locations are spread across Europe, and each location has its own responsibilities.

• ESTEC (European Space Research and Technology Centre) forms the design department for most of ESA's spacecraft and is located in Noordwijk. ESA Education is also located there.
• ESOC (European Space Operations Centre) is the flight control center for ESA's satellites and is located in Darmstadt, Germany.
• EAC (European Astronaut Centre) provides training for astronauts for future missions and is based in Cologne.
• ESRIN (European Space Research Institute) is based in Frascati, near Rome in Italy. ESRIN collects, manages, and distributes data from ESA's satellites to ESA's partners and serves as an information technology center.
• ESAC (European Space Astronomy Centre) is the base of the operational centers related to astronomy and planetary missions. It is located in Villafranca del Castillo, Villanueva de la Cañada, near Madrid in Spain.

ESA also has offices in Brussels, Houston, Washington, and Moscow, and various ground stations elsewhere in the world. ESA contributes two-thirds of the costs of the Centre Spatial Guyanais near Kourou (French Guiana). ESA Education, which promotes space education at a European level, has established local offices in various countries to fulfill this mission at a national level, aligned with national (and regional) education. They bear the name ESERO, an abbreviation for European Space Education Resource Office. For each of these national services, there is a local partner that hosts and co-finances them. For the Netherlands, the partner is NEMO Science Centre (Amsterdam). Thanks for the information and stamps from Peter Fidder and other members of the Space Philately Club (RFC).
