Ariane 6

Ariane 6 is a European expendable launch system developed by ArianeGroup for the European Space Agency, replacing the Ariane 5. It is a two-stage rocket that uses liquid hydrogen and liquid oxygen engines, with the first stage powered by an upgraded Vulcain engine and the second stage powered by the Vinci engine. The Ariane 6 has two variants: Ariane 62, which uses two solid rocket boosters, and Ariane 64, which uses four. The rocket experienced a partial failure on its first launch in 2024, but successfully launched its second commercial payload on March 6, 2025. The Ariane 6 was designed to halve launch costs and increase annual capacity, but it failed to meet cost targets and has been criticized for its high costs and lack of reusability compared to competitors' rockets.learn more on wikipedia
