Europe's space agency holds the record for the most distant landing
In 2005 a European probe called Huygens parachuted onto Titan, Saturn's largest moon, the farthest from Earth any spacecraft has ever touched down. Nine years later another European craft, Rosetta, became the first to orbit a comet and dropped a lander onto its surface. Both came from an agency born of two struggling predecessors.
After the Second World War, many European scientists left for the United States, and those who stayed realised no single nation could keep pace with the superpowers. In 1958, months after Sputnik, the physicists Edoardo Amaldi of Italy and Pierre Auger of France met to discuss a shared agency. Europe ended up with two: ESRO for research satellites, led by Auger, and ELDO for rockets. ESRO launched seven satellites between 1968 and 1972, but ELDO never produced a working launcher, and both were starved of money. In 1975 they merged into the European Space Agency, with ten founding members including France, West Germany, Italy and the United Kingdom.
Success came quickly. The gamma-ray satellite Cos-B went up the year ESA was founded, and the International Ultraviolet Explorer, built with NASA and launched in 1978, worked for 18 years. Giotto, ESA's first deep-space mission, flew past Halley's Comet in 1986. On the launch side, the Ariane rockets inherited ELDO's job. Ariane 4, flying from 1988 to 2003, made Europe the leading commercial launch provider of the 1990s, and Ariane 5 recovered from a failed debut in 1996 to rack up 112 successful launches by 2023.
Human spaceflight took a cooperative route. Ulf Merbold became the first ESA astronaut in 1983, flying on the Space Shuttle with the European-built Spacelab module. Plans for a European crewed spaceplane called Hermes were dropped, and the proposed Columbus free-flying laboratory was redesigned as a module attached to the International Space Station in 2008. ESA now builds the service module that powers NASA's Orion lunar capsule.
The 2000s brought Europe's first orbiters around the Moon, Mars and Venus, and the Gaia telescope later compiled the most precise three-dimensional map of the stars ever made. Headquartered in Paris with 23 member states and around 3,000 staff, ESA had a 2026 budget near €8.3 billion. In 2025 its members expanded its mandate to include defence.
