Agence spatiale européenne
The European Space Agency (ESA) is an intergovernmental organization dedicated to space exploration, with 22 member states. Founded in 1975, ESA shapes Europe's space capabilities, ensuring investments in space deliver benefits to European citizens, working across the entire space sector. ESA develops and operates Earth observation, navigation, telecommunications, and astronomy satellites and sends probes to explore the solar system, partnering with agencies like NASA, JAXA and commercial partners like Airbus. Key programs include the development of launch vehicles like Ariane and Vega, the Galileo satellite navigation system, and missions like Rosetta and BepiColombo.
