What is ESA?
The European Space Agency (ESA) is an intergovernmental organisation established in 1975, headquartered in Paris, with 22 member states. With an annual budget of approximately €7.8 billion in 2023, ESA is one of the world's four major space agencies alongside NASA (USA), CNSA (China), and Roscosmos (Russia). ESA is responsible for coordinating Europe's civil space programme — distinct from national programmes (CNES in France, DLR in Germany, ASI in Italy) which continue alongside ESA.
Key programmes
Copernicus: The world's largest Earth observation programme (jointly with the EU), operating Sentinel-1 (SAR), Sentinel-2 (optical multispectral), Sentinel-3 (ocean colour and temperature), Sentinel-5P (atmospheric chemistry), and Sentinel-6 (sea level altimetry). Copernicus data is freely available globally. Galileo: Europe's global satellite navigation system — 30 active satellites at 23,222 km MEO, providing positioning accuracy better than 1 metre with the High Accuracy Service. Ariane: ESA-developed launch vehicle family (Ariane 5 retired 2023, Ariane 6 in service from 2024). Science missions: Hubble Space Telescope (joint with NASA), Rosetta comet mission, Mars Express, Solar Orbiter, JUICE (Jupiter Icy Moons Explorer).
ESA BIC: supporting the New Space industry
ESA's Business Incubation Centre (ESA BIC) programme provides startups developing space-related products and services with funding (up to €50,000), technical expertise, business support, and access to ESA data and facilities. ESA BIC centres operate across 23 countries; over 1,000 startups have been supported since 2003, generating thousands of jobs and hundreds of millions in follow-on investment.
