Ariane (rocket)
Ariane is a series of European launch vehicles developed on behalf of the European Space Agency (ESA) by a subsidiary of the European aerospace company Airbus Group (formerly EADS). The Ariane rockets are launched from the Kourou spaceport in French Guiana , 5 ° north of the equator.
history
The name Ariane comes from the French name for the fertility goddess Ariadne from Greek mythology . The company Arianespace was founded in March 1980 and has since taken over the financing, production, sale and launch of the Ariane rockets. This company is owned by various European space companies. The sole main contractor for the series production of the current rocket, Ariane 5 , is the Airbus Group subsidiary Airbus Defense & Space. Although extensive increases in the performance of Ariane 5 are still being planned, the start of the development of the successor version Ariane 6 is already being prepared.
The doctrine , originally from France, of securing “autonomous access to space” ( Charles de Gaulle ) and thus being able to place satellites in orbit independently of the United States and the Soviet Union , led to the establishment of the European Launcher Development Organization in London in 1964 ( ELDO) through Belgium , France , Italy , Germany , Great Britain , the Netherlands and Australia .
The decisive factor was involved Hubert Curien , the 1976-1984 president of the CNES ( National Center for Space Research shortly CNES was). He was responsible for French space policy and especially the development of the rocket. Later he was called the father of Ariane .
The reason for the Australian commitment was the space site in Woomera , which was very beneficial for the development. The rockets developed by ELDO were given the name Europa . The Europa 1 and Europa 2 models were never used commercially; the Europa 3 then emerged as the Ariane 1 .
Development and sales
The Ariane rockets were developed by space companies from the ESA member states on behalf of ESA. Each Member State participating in the project made financial resources available. In return, the industry of the respective state received development contracts from ESA to the value of the development center contribution paid by the state. Since the contract for the series production of a total of 65 Ariane 5 launch vehicles, the EADS subsidiary EADS Astrium Transportation has been the sole prime contractor and is now responsible for the delivery of the Ariane 5 to Arianespace. Previously, the start-up company Arianespace had to order the individual parts of the rocket from various companies and then have them assembled by another selected company.

- ↑ P = solid fuel booster
- Ariane 5 ECA - The current version of Ariane 5. It is a further developed Ariane 5 launcher with the cryogenic ESC-A upper stage in order to meet the steadily increasing demand for transport options for medium and heavier satellites in the civil market.
- Ariane 5 ES ATV - this version of the Ariane 5 launcher carried the Automated Transfer Vehicle ( ATV ) to the international space station ISS. This space transporter delivered, among other things, supplies such as food, oxygen and fresh water or the fuel for the drive system of the station. But also the height correction of the space station, the so-called "reboost", happened with the thrust of this space transporter.
- Ariane 5 ES Galileo - this version of the Ariane 5 launcher was developed to put the satellites of the European Galileo program into orbit. 12 Galileo satellites were launched during 3 launches. The last start of an Ariane 5 ES was on July 25, 2018.
- Ariane 5 ME - deleted version of Ariane 5 with the new ESC-B upper level.
Ariane 6
The Ariane 6 is currently under development and is designed for a payload of 5 t to 11.5 t in the GTO . After the meeting of the ESA Council on April 17, 2019, Arianespace commissioned the production of the first 14 Ariane 6s. The first flight is planned for 2021.

Ariane 7 / Ariane NEXT
Ariane 7 (also Ariane NEXT ) is a concept for a methane-powered and reusable rocket. It will use the “Prometheus” liquid engines, which are manufactured using a 3D printing process. In preparation for Ariane NEXT, a research program for the landing of rockets is planned, which will initially be carried out with the help of the smaller demonstration research rocket “Callisto” and in the next step with the large-scale rocket “Themis”. Ariane NEXT could be operational by the end of the 2020s.
Modelling
In 1987 Lambert Schelter built a 5.40 meter long airworthy model of the Ariane, which is now in the Hermann Oberth Space Museum in Feucht. A 4.5-meter-long and 85-kilogram airworthy model of the Ariane 4, which was built by a working group of the Advanced Rocketry Group of Switzerland (ARGOS), was successfully launched in 2002 in Amarillo , Texas and twice in Val de Ruz near Neuchâtel .
Community of Ariane Cities
The Communauté des Villes Ariane (CVA, "Community of Ariane Cities") connects the EU locations that are involved in Ariane production.
