Slovenia is an Associate Member. Canada takes part in some projects under a cooperation agreement.

Bulgaria, Croatia, Cyprus, Malta, Latvia, Lithuania and Slovakia have cooperation agreements with ESA.

Where is ESA located?

ESA`s headquarters are in Paris which is where policies and programmes are decided. ESA also has sites in a number of European countries, each of which has different responsibilities:

EAC, the European Astronauts Centre in Cologne, Germany;
ESAC, the European Space Astronomy Centre, in Villanueva de la Canada, Madrid, Spain;
ESOC, the European Space Operations Centre in Darmstadt, Germany;
ESRIN, the ESA centre for Earth Observation, in Frascati, near Rome, Italy;
ESTEC, the European Space Research and Technology Centre, Noordwijk, the Netherlands.
ECSAT, the European Centre for Space Applications and Telecommunications, Harwell, Oxfordshire, United Kingdom.
ESA Redu Centre, Belgium.

ESA also has liaison offices in Belgium, USA and Russia; a launch base in French Guiana and ground/tracking stations in various parts of the world.

How many people work for ESA?

There are around 2200 staff working for ESA, from all the Member States and include scientists, engineers, information technology specialists and administrative personnel.

Where do ESA’s funds come from?

ESA’s mandatory activities (space science programmes and the general budget) are funded by a financial contribution from all the Agency’s Member States, calculated in accordance with each country’s gross national product. In addition, ESA conducts a number of optional programmes. Each Member State decides in which optional programme they wish to participate and the amount they wish to contribute.

How big is ESA’s budget?

ESA`s budget for 2017 is €5.75 billion. ESA operates on the basis of geographical return, i.e. it invests in each Member State, through industrial contracts for space programmes, an amount more or less equivalent to each country’s contribution.

How much does each European spend on ESA?

European per capita investment in space is very little. On average, every citizen of an ESA Member State pays, in taxes for expenditure on space, about the same as the price of a cinema ticket (in USA, investment in civilian space activities is almost four times as much).

How does ESA operate?

The Council is ESA`s governing body and provides the basic policy guidelines within which ESA develops the European space programme. Each Member State is represented on the Council and has one vote, regardless of its size or financial contribution.

ESA is headed by a Director General who is elected by the Council every four years. Each individual research sector has its own Directorate and reports directly to the Director General. The present Director General of ESA is Jan Woerner.
