Frequently asked questions
What is European Space Agency?
ESA is an intergovernmental organisation through which European countries pool resources for space science, exploration, Earth observation and space technology.
When was ESA founded?
1975 marks ESA creation and convention signature. The convention entered into force in 1980. These are distinct institutional milestones.
How did ESA develop?
In 1975, European governments brought these strands together under ESA. The convention was signed on May 30, 1975, although it did not formally enter into force until October 30, 1980. ESA inherited ESRO activities and developed a broader programme that included applications as well as science. Cos-B, launched in 1975 to investigate gamma rays, was an early example of this new institutional framework in action.
Is ESA an agency of the European Union?
ESA is a separate intergovernmental organisation. It cooperates with the European Union, but the two have different institutional structures and memberships.
Why does ESA matter in space history?
ESA demonstrates how countries can share the costs and knowledge required for ambitious space missions while retaining national research and industrial capabilities.
