The Final Act of the Conference of Plenipotentiaries and the associated Resolutions established the conditions for signature of the Convention and for the functioning of the European Space Agency.
On 30 May 1975, the Convention was signed by: the Federal Republic of Germany, the Kingdom of Belgium, the Kingdom of Denmark, Spain, the French Republic, the Italian Republic, the Kingdom of the Netherlands, the United Kingdom of Great Britain and Northern Ireland, the Kingdom of Sweden, and the Swiss Confederation.

The European Space Agency is an inter-governmental organisation, which thus enjoys legal personality. It counts today 20 Member States: 18 states of the EU (Austria, Belgium, Czech Republic, Germany, Denmark, Spain, Finland, France, Italy, Greece, Ireland, Luxembourg, the Netherlands, Portugal, Poland, Romania, Sweden, United Kingdom) plus Norway and Switzerland. Estonia and Hungary are about to join.
