# Ariane Ariane is Europe's family of heavy-lift rockets, developed under the [[European Space Agency]] and flown from the Guiana Space Centre in Kourou, French Guiana. It exists because of one political lesson, and every major decision about it since the 1970s has been about that lesson: **if you cannot launch your own satellites, someone else decides which of your satellites get launched.** ## Origin: a lesson in dependence In the early 1970s, France and West Germany built Symphonie, a pair of communications satellites, and had no European rocket to put them up. The United States agreed to launch them, but on the condition that they not be used for commercial service that would compete with American satellite operators. European governments took the point. France pushed through a European launcher program, and the first Ariane flew on Christmas Eve 1979. The name is the French form of Ariadne, the mythological figure who gave Theseus the thread out of the labyrinth. In 1980 Europe created Arianespace to sell Ariane launches — the world's first commercial launch company. Through the 1980s and 1990s, Ariane rockets carried a large share of the world's commercial communications satellites, which made launch a European export business, not just a sovereignty project. ## The generations - **Ariane 1–4 (1979–2003).** The workhorses that built Europe's commercial launch business. - **Ariane 5 (1996–2023).** Its first flight in June 1996 blew up 37 seconds after launch because of a software error, one of the most-studied engineering failures ever. It went on to fly 117 times. Its last famous payload was the James Webb Space Telescope, launched on Christmas Day 2021. It retired in July 2023. - **Ariane 6 (2024–).** Built cheaper and more flexible than Ariane 5, in two versions: **Ariane 62** with two strap-on boosters and **Ariane 64** with four. It first flew on 9 July 2024. The Ariane 64 debuted on 12 February 2026, carrying 32 satellites for [[Amazon]]'s Amazon Leo internet constellation. By the end of August 2026, Ariane 6 had flown nine missions, with another Amazon Leo launch scheduled for late November 2026. Ariane is built by ArianeGroup, a joint venture of Airbus and Safran, with Arianespace (now an ArianeGroup subsidiary) as the operator. Europe also flies the smaller, Italian-led Vega C for lighter payloads. ## The gap year Ariane 5 retired before Ariane 6 was ready, Vega C was grounded after a 2022 failure, and Russia's Soyuz had left Kourou after the invasion of [[Ukraine]]. Between July 2023 and July 2024, Europe had no way to launch a large satellite on its own. Its space agency and the [[European Union]] bought rides on [[SpaceX]] Falcon 9 rockets instead. That year, more than any white paper, turned "strategic autonomy" from a slogan into a budget line. ## The cost problem Ariane 6 is expendable — every rocket is thrown away after one flight — in a market that [[SpaceX]] reshaped around reusable boosters. It costs more per launch than Falcon 9, and European governments agreed in 2023 to support its operations with ongoing public payments. Critics call it a subsidy for a rocket designed for the market of 2014. Supporters reply that the alternative is depending on a single foreign company for access to orbit. Both sides are describing the same trade-off. The [[European Space Agency]]'s launcher competition for new commercial rockets is Europe's attempt to stop having to choose. There is an irony in the order book, too. Ariane 6's biggest commercial customer is Amazon, whose Leo constellation is the leading Western competitor to [[Elon Musk]]'s [[Starlink]]. Europe's sovereign rocket is partly paid for by one American billionaire's race against another, [[Jeff Bezos]] versus Musk. ## Why it's on the map Ariane is the longest-running answer to a question this wiki keeps asking: what does it cost to *not* depend on [[SpaceX]]? The American right tends to treat Musk's launch dominance as proof that markets beat governments. Europe's answer is that a market with one dominant seller is a dependency, and a dependency has a price that does not show up on an invoice. Ariane is what that price looks like when a government decides to pay it. ## See also - [[European Space Agency]] — the agency behind Ariane - [[Space Launch Infrastructure]] — launch as a strategic chokepoint - [[SpaceX]] · [[Starlink]] · [[Amazon]] — the commercial competition - [[Soyuz]] — the Russian rocket that left Europe's spaceport in 2022 - [[H3 Rocket]] · [[GSLV]] · [[Long March Rockets]] — the other national launchers - [[Space Hub]] — the parent hub
