Lampoldshausen is the historic site for space propulsion testing in Germany. With the support of the DLR and ArianeGroup, all European space propulsion systems are tested there which relies on its unique in-vacuum condition facilities across Europe. Its test bench facilities are also capable of welcoming high thrust engine such as Ariane 5’s Vulcain 2 cryogenic engine for hot firing tests. ArianeGroup engineers in Lampoldshausen are also in charge of developing, assembling and testing the hypergolic propulsion engines and thrusters used for launchers upper stages and in-orbit satellite propulsion.

Les Mureaux is the heart of European launcher systems development and integration. This is there where the first stage of Ariane 5 has been developed and is now manufactured. It is capable of carrying 150 tons of cryogenic propellant and burning it to boost the launcher upper stage and its payload into space. Besides manufacturing the Ariane 5 first stage, the design offices based in Les Mureaux are responsible for designing the space launch vehicles, spacecraft such as the Automated Transfer Vehicle (ATV) and other space equipment for satellites. The new Ariane 6 launch vehicle is currently developed in Les Mureaux and its first stage will be assembled and

Drawing on more than 60 years of experience of rocket propulsion, ArianeGroup designs, develops and produces entire liquid propulsion systems for launchers. It is the prime for cryogenic propulsion for Ariane 5s, notably for production of the Vulcain 2 and HM7B engines, as well as for cryogenic propulsion development of the new upper stage for Ariane 6 with the Vinci engine. ArianeGroup is further developing a new generation of low cost and multi-ignition semi-cryogenic engine called Prometheus.

Arianespace was created in 1980 on the basis of the assets consisting of the Ariane family of launchers developed by ESA and CNES, and was the first commercial firm for the launching of satellites. Its shareholders are CNES and the main European space sector firms, representing ten European countries. In 2011, the Ariane 5 launcher was joined at Europe’s Spaceport by Soyuz and in 2012 by Vega. Arianespace has launched more than half the world’s commercial satellites currently in service.
