ESA - European Space Agency
1975-present
Who
Twenty-three member states, headquarters in Paris, around 3,000 staff, a 2026 budget of €8.3 bn contributed by agreement at ministerial councils - European spaceflight runs on consensus, and it shows in the engineering: the agency's signature missions are the patient, instrument-heavy kind.
Why it matters
Rosetta orbited comet 67P/Churyumov-Gerasimenko in 2014 after a decade of cruise and, on 12 Nov 2014, dropped Philae - the first landing ever on a comet, on a body whose gravity could not hold a strong breeze. Juice is en route to Jupiter (launched 2023, arrival 2031). The Rosalind Franklin rover - first designed to drill 2 m deeper into Mars than any rover has gone - was rebuilt as an ESA-led programme after the 2022 split with its Russian partner, and as of 2026 is booked for a 2028 launch on Falcon Heavy. Ariane 6 returned independent European access to orbit: first flight 9 July 2024, fully nominal on its second, 6 March 2025. Copernicus quietly runs the civil Earth-observation service that weather models and emergency responders actually use. And the partnership evidence sits in this collection: Hubble and JWST are both NASA-ESA programmes. Status: September 2026.
Lineage
Merged from ESRO and ELDO in 1975; the Ariane line from the independent-launch ambition of the 1970s. Cooperating member Canada and a decade of Soyuz cooperation at Kourou (ended after 2022) are part of the same web.
