Ariane 5 is a European expendable launch system designed to deliver payloads into geostationary transfer orbit or low Earth orbit. It is manufactured under the authority of the European Space Agency (ESA) and the Centre National d'Etudes Spatiales (CNES), with EADS Astrium Space Transportation (Astrium) as prime contractor, leading a consortium of sub-contractors. The rocket is operated and marketed by Arianespace as part of the Ariane programme. Astrium builds the rockets in Europe and Arianespace launches them from the Guiana Space Centre.
