The European Space Agency (ESA) has been shaping Europe’s journey in space since 1975, but the ambition to reach beyond Earth began much earlier.
In 1959, two visionary scientists — Italy’s Edoardo Amaldi and France’s Pierre Auger — recognised that no single European nation could compete with the enormous space programmes of the United States and the Soviet Union. Having already played key roles in creating CERN, they believed that Europe’s future in space depended on collaboration.
Their vision quickly gained momentum. Within a year, several European governments established a commission to explore a joint space effort, leading to the creation of two organisations in 1964: the European Space Research Organisation (ESRO) and the European Launcher Development Organisation (ELDO).
ESRO focused on science and satellites, achieving early success and establishing facilities that remain at the heart of ESA today, including ESTEC in the Netherlands, ESRIN in Italy and ESOC in Germany. ELDO pursued Europe’s first launcher, Europa, but faced technical and political challenges, and ceased operations in 1974.
By this time, it was clear that Europe needed a single organisation to unite its space ambitions. After a series of European Space Conferences, European governments decided to create a single ‘European space agency’. That organisation became ESA.

On 30 May 1975, ten founding Member States signed the ESA Convention, creating a uniquely flexible agency that combined a shared core programme with optional initiatives driven by national priorities. This model allowed France to lead the Ariane launcher programme, the UK to pioneer satellite applications and Germany to develop Spacelab for NASA’s Space Shuttle. The newly formed agency became the world’s third-largest space programme, next to the United States and Soviet Union.
Since then, ESA has helped Europe achieve some of the most remarkable milestones in space exploration. From Giotto’s historic encounter with Comet Halley and Huygens’ landing on Titan, to Rosetta’s landing on a comet, ESA missions have expanded our understanding of the Solar System and beyond. Missions such as SOHO and Planck have transformed our knowledge of the Sun and the origins of the Universe.
ESA has also secured Europe’s independent access to space through the Ariane and Vega launchers and Europe’s Spaceport in French Guiana. The agency has driven major advances in Earth observation, navigation and telecommunications, including Copernicus and Galileo — programmes that deliver daily benefits to people across Europe and around the world.
European astronauts have been flying in space for more than 40 years, while ESA remains a key partner on the International Space Station. Today, the agency is helping shape the next era of exploration by providing the European Service Modules for NASA’s Artemis missions, ensuring that Europe plays a leading role in humankind’s return to the Moon and future journeys deeper into space.
ESA Historical Archive
The ESA Archives both preserves ESA’s institutional memory and promotes and exploits Europe’s technical and scientific legacy in space. A dedicated website makes their vast resources available online to anyone with an interest in the story and benefits of European endeavours and cooperation in space.
