Ariane 5 is a retired European heavy-lift space launch vehicle operated by Arianespace for the European Space Agency (ESA). It was launched from the Guiana Space Centre (CSG) in French Guiana. It was used to deliver payloads into geostationary transfer orbit (GTO), low Earth orbit (LEO) or further into space. The launch vehicle had a streak of 82 consecutive successful launches between 9 April 2003 and 12 December 2017. Since 2014, Ariane 6, a direct successor system, first launched in 2024.
Arianespace SA is a French company founded in March 1980 as the world's first commercial launch service provider. It operates two launch vehicles: Vega C, a small-lift rocket, and Ariane 6, a medium-to-heavy-lift rocket. Arianespace is a subsidiary of ArianeGroup, a joint venture between Airbus and Safran.
Ariane is a series of European civilian expendable launch vehicles for space launch use. The name comes from the French spelling of the mythological character Ariadne. France first proposed the Ariane project and it was officially agreed upon at the end of 1973 after discussions between France, Germany and the UK. The project was Western Europe's second attempt at developing its own launcher following the unsuccessful Europa project. The Ariane project was code-named L3S.
The Europa rocket was an early expendable launch system of the European Launcher Development Organisation (ELDO), which was the precursor to the European Space Agency (ESA). It was developed with the aim to delivering space access technology, and more specifically to facilitate the deployment of European-wide telecommunication and meteorological satellites into orbit.
Ariane 1 was the first rocket in the Ariane family of expendable launch systems. It was developed for and operated by the European Space Agency (ESA), which had been formed in 1973, the same year that development of the launcher had commenced. Aérospatiale was designated to lead the programme. Ariane 1 was the first launcher to be developed with the primary purpose of sending commercial satellites into geosynchronous orbit. Crucially, it was designed with the ability of sending a pair of satellites into orbit on a single launcher, thus reducing costs.
CNES is the French national space agency. Headquartered in central Paris, the agency comes under the supervision of the ministries of the Armed Forces, Economy and Finance and Higher Education, Research and Innovation.
Vega was an expendable small-lift launch vehicle operated by Arianespace, produced by Avio, and jointly developed by the Italian Space Agency (ASI) and the European Space Agency (ESA). Development began in 1998 and the first launch took place from the Guiana Space Centre on 13 February 2012. It was the 8th most launched small lift launch vehicle in history. The final flight of the rocket took place on 5 September 2024, after being replaced by the improved Vega C, already in use since 2022.
Avio S.p.A. is an Italian company operating in the aerospace sector with its head office in Colleferro near Rome, Italy. Founded in 1908, it is present in Italy and abroad with different commercial offices and 10 production sites. Avio operates in:
Vulcain is a family of European first stage rocket engines for Ariane 5 and Ariane 6. Its development began in 1988 and the first flight was completed in 1996. The updated version of the engine, Vulcain 2, was first successfully flown in 2005. Both members of the family use liquid oxygen/liquid hydrogen cryogenic fuel. The new version for Ariane 6 is called Vulcain 2.1.
The Future Launchers Preparatory Programme (FLPP) is a technology development and maturation programme of the European Space Agency (ESA). It develops technologies for the application in future European launch vehicles (launchers) and in upgrades to existing launch vehicles. By this it helps to reduce time, risk and cost of launcher development programmes.
Started in 2004, the programmes initial objective was to develop technologies for the Next Generation Launcher (NGL) to follow Ariane 5. With the inception of the Ariane 6 project, the focus of FLPP was shifted to a general development of new technologies for European launchers.
FLPP develops and matures technologies that are deemed promising for future application but currently do not have a sufficiently high technology readiness level (TRL) to allow a clear assessment of their performance and associated risk. Those technologies typically have an initial TRL of 3 or lower. The objective is to raise the TRL up to about 6, thus creating solutions which are proven under relevant conditions and can be integrated into development programmes with reduced cost and limited risk.
Ariane 6 is a European expendable launch system operated by Arianespace and developed and produced by ArianeGroup on behalf of the European Space Agency (ESA). It replaces Ariane 5, as part of the Ariane launch vehicle family.
Space launch market competition is the manifestation of market forces in the launch service provider business. In particular it is the trend of competitive dynamics among payload transport capabilities at diverse prices having a greater influence on launch purchasing than the traditional political considerations of country of manufacture or the national entity using, regulating or licensing the launch service.
Saenger or Sänger was a West German concept design for a two-stage-to-orbit spaceplane. It is named after Eugen Sänger, who had been a key figure in the development of the concept for aerospace company Junkers.
Liquid Fly-back Booster (LFBB) was a German Aerospace Center's (DLR's) project concept to develop a liquid rocket booster capable of reuse for Ariane 1 in order to significantly reduce the high cost of space transportation and increase environmental friendliness. lrb would replace the existing liquid rocket boosters, providing main thrust during the countdown. Once separated, two winged boosters would perform an atmospheric entry, go back autonomously to the French Guiana, and land horizontally on the airport like an aeroplane.
ArianeGroup is an aerospace company based in France. A joint venture between Airbus and Safran, the company was founded in 2015 and is headquartered in Issy-les-Moulineaux near Paris. It consists of three core groups: aerospace, defence, and security. ArianeGroup has developed its next-generation two-stage Ariane 6 launch vehicle, which succeeded the Ariane 5 rocket, that had more than 110 launches. The new vehicle offers two variants that will be capable of carrying between 10,350 and 21,650 kilograms. The first launch of Ariane 6 occurred on July 9 2024.
Miura 5 is a two-stage European orbital recoverable launch vehicle currently under development by the Spanish company PLD Space. In a standard two-stage configuration, it will have a length of 34 m, be capable of inserting 1000 kg of payload into a low Earth orbit (LEO), featuring an optional kick stage that can circularize the orbits of satellites.
CALLISTO is a reusable VTVL demonstrator propelled by a small 40 kN Japanese LOX-LH2 rocket engine. It is being developed jointly by the French (CNES), German (DLR) and Japanese (JAXA) national space agencies.
The Themis programme is an ongoing European Space Agency programme and carried by prime contractor, ArianeGroup, aiming to develop a prototype reusable rocket first stage and plans to conduct demonstration flights. The prototype rocket will also be called Themis.
M10 is a liquid-fuel upper-stage rocket engine in development by Avio on behalf of European Space Agency for use on Vega E. The engine, initially known as LM10-MIRA, was a derivation of the existing Russian RD-0146 engine and result of a past collaboration between Avio and Chemical Automatics Design Bureau (KBKhA) ended in 2014 after the escalation of the Russo-Ukrainian conflict and consequent economic sanctions. On May 6, 2022 engine testing campaign started at Salto di Quirra, Sardinia, with consequent maiden flight on a Vega-E launcher expected by 2026 from Guiana Space Centre.
Ariane Next—also known as SALTO —is a future European Space Agency rocket being developed in the 2020s by ArianeGroup. This partially reusable launcher is planned to succeed Ariane 6, with an entry into service in the 2030s. The objective of the new launcher is to halve the launch costs compared with Ariane 6. The preferred architecture is that of the Falcon 9 rocket while using an engine burning a mixture of liquid methane and liquid oxygen. The first technological demonstrators are under development.
