Arianespace undertakes the operation and marketing of the Ariane program. The company offers a number of different launch vehicles: the heavy-lift Ariane 5 for dual launches to geostationary transfer orbit, the Soyuz-2 as a medium-lift alternative, and the solid-fueled Vega for lighter payloads.
The formation of Arianespace SA is closely associated with the desire of several European nations to pursue joint collaboration in the field of space exploration and the formation of a pan-national organization, the European Space Agency (ESA), to oversee such an undertaking in 1973. Prior to the ESA’s formation, France had been lobbying for the development of a new European expendable launch system to serve as a replacement for the Europa rocket. Accordingly, one of the first programs launched by the ESA was the Ariane heavy launcher. The express purpose of this launcher was to facilitate the delivery of commercial satellites into geosynchronous orbit.
As of May 2021, Arianespace had launched more than 850 satellites in 287 launches over 41 years. The first commercial flight managed by the new entity was Spacenet F1 launched on 23 May 1984. Arianespace uses the Guiana Space Centre in French Guiana as its main launch site. Through shareholding in Starsem, it can also offer commercial Soyuz launches from the Baikonur spaceport in Kazakhstan. It has its headquarters in Évry-Courcouronnes, Essonne, France.
