Ariane 5 upper stage EPS (Etage à Propergols Stockables) - EADS Astrium takes responsibility for the development, integration and start preparation of the complete upper stage EPS including the Aestus engine. Ariane 5 symbolizes a major key for Europe’s unrestricted, independent access to space. EADS Astrium is the key to this success. Its experience dates back to the beginnings of the European space industry, with the Diamant and early Ariane launchers. The new-generation Ariane 5 continues the tradition of its famous predecessors, Ariane 1 to 4, but features a radically new design. Since 2005, the latest heavy-lift version of Ariane 5 has provided increased Geostationary Transfer Orbit payload capacity, up to 10 tonnes on dual launches, to meet the evolving demands of both commercial and institutional markets. It incorporates a new cryogenic upper stage carrying over 14 tonnes of propellants, and a strengthened cryogenic main stage, powered by the new Vulcain 2 engine.
