'''Ariane 5''' ({{IPA|fr|aʁjan sɛ̃k|lang}}) 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. In development since 2014,<ref name=ars20210622>{{cite news |last=Berger|first=Eric |url=https://arstechnica.com/science/2021/06/europes-space-chief-appoints-task-force-to-assess-ariane-6-schedule-concerns/ |title=The Ariane 6 debut is slipping again as Europe hopes for a late 2022 launch |work=Ars Technica |date=21 June 2021 |access-date=8 October 2021}}</ref> Ariane 6, a direct successor system was first launched in 2024.<ref name="mtg-s">{{cite web|last=Krebs|first=Gunter D. |title=MTG-S 1, 2 (Meteosat 13, 16 / Sentinel 4A, 4B)|publisher=Gunter's Space Page|access-date=May 13, 2023|url=https://space.skyrocket.de/doc_sdat/mtg-s.htm}}</ref>

The system was designed as an expendable launch vehicle by the ''Centre National d'Études Spatiales'' (CNES), the French government's space agency, in cooperation with various European partners. Despite not being a direct derivative of its predecessor launch vehicle program, it was classified as part of the Ariane rocket family. Aérospatiale, and later ArianeGroup, was the prime contractor for the manufacturing of the vehicles, leading a multi-country consortium of other European contractors. Ariane 5 was originally intended to launch the Hermes spacecraft, and thus it was rated for human space launches.

Since its first launch, Ariane 5 was refined in successive versions: "G", "G+", "GS", "ECA", and finally, "ES". The system had a commonly used dual-launch capability, where up to two large geostationary belt communication satellites can be mounted using a '''SYLDA''' (''Système de Lancement Double Ariane'', meaning "Ariane Double-Launch System") carrier system. Up to three, somewhat smaller, main satellites are possible depending on size using a '''SPELTRA''' (''Structure Porteuse Externe Lancement Triple Ariane'', which translates to "Ariane Triple-Launch External Carrier Structure"). Up to eight secondary payloads, usually small experiment packages or minisatellites, could be carried with an '''ASAP''' (Ariane Structure for Auxiliary Payloads) platform.

Following the launch of 15 August 2020, Arianespace signed the contracts for the last eight Ariane 5 launches, before it was succeeded by the new Ariane 6 launcher, according to Daniel Neuenschwander, director of space transportation at the ESA.<ref name="Ariane6">{{cite web|url=https://spaceflightnow.com/2020/08/15/debuting-upgrades-ariane-5-rocket-deploys-three-u-s-built-satellites-in-orbit/|title=Debuting upgrades, Ariane 5 rocket deploys three U.S.-built satellites in orbit|publisher=Spaceflight Now|date=15 August 2020|access-date=17 August 2020}}</ref><ref name=mtg-s/> Ariane 5 flew its final mission on 5 July 2023.<ref>{{Cite web |last=Svenson |first=Adam |date=2023-07-06 |title=Last Ariane 5 Mission Leaves Europe Without Launch Capacity |url=https://airspacenews.net/last-ariane-5-mission-leaves-europe-without-launch-capacity/ |access-date=2023-07-23 |website=AIR SPACE News |archive-date=23 July 2023 |archive-url=https://web.archive.org/web/20230723081139/https://airspacenews.net/last-ariane-5-mission-leaves-europe-without-launch-capacity/ |url-status=dead }}</ref>

Ariane 5's cryogenic H173 main stage (H158 for Ariane 5G, G+, and GS) was called the EPC (''Étage Principal Cryotechnique'' — Cryotechnic Main Stage). It consisted of a {{cvt|5.4|m}} diameter by {{cvt|30.5|m}} high tank with two compartments, one for liquid oxygen and one for liquid hydrogen, and a Vulcain 2 engine at the base with a vacuum thrust of {{cvt|1390|kN}}. The H173 EPC weighed about {{cvt|189|t|lb}}, including {{cvt|175|t|lb}} of propellant.<ref name=a5dsslr>{{cite web|title=Ariane 5 Data Sheet|url=http://www.spacelaunchreport.com/ariane5.html|publisher=Space Launch Report|access-date=8 November 2014|archive-url=https://web.archive.org/web/20141108044627/http://www.spacelaunchreport.com/ariane5.html|archive-date=8 November 2014|url-status=usurped}}</ref> After the main cryogenic stage runs out of fuel, it re-entered the atmosphere for an ocean splashdown.

=== Solid boosters === Attached to the sides were two P241 (P238 for Ariane 5G and G+) solid rocket boosters (SRBs or EAPs from the French ''Étages d'Accélération à Poudre'' — {{Literal translation|Powder Acceleration Stages}}), each weighing about {{cvt|277|t|lb}} full and delivering a thrust of about {{cvt|7080|kN}}. They were fueled by a mix of ammonium perchlorate (68%) and aluminium fuel (18%) and HTPB (14%). They each burned for 130 seconds before being dropped into the ocean. The SRBs were usually allowed to sink to the bottom of the ocean, but, like the Space Shuttle Solid Rocket Boosters, they could be recovered with parachutes, and this was occasionally done for post-flight analysis. Unlike Space Shuttle SRBs, Ariane 5 boosters were not reused. The most recent attempt was for the first Ariane 5 ECA mission in 2009. One of the two boosters was successfully recovered and returned to the Guiana Space Center for analysis.<ref name="FranceScience">{{cite web|url=http://www.france-science.org/spip.php?article399#3-ARIANE-5-ECA-BOOSTER-RECOVERED|title=France in Space #387|publisher=Office of Science and Technology Embassy of France in the USA|url-status=dead|archive-url=https://web.archive.org/web/20090125213207/http://www.france-science.org/spip.php?article399#3-ARIANE-5-ECA-BOOSTER-RECOVERED|archive-date=25 January 2009}}</ref> Prior to that mission, the last such recovery and testing was done in 2003.{{Citation needed|date=January 2022}}

=== Second stage === thumb|upright|left|EPS Upper Stage used on Ariane 5ES

The second stage was on top of the main stage and below the payload. The original Ariane — Ariane 5G — used the EPS (''Étage à Propergols Stockables'' — Storable Propellant Stage), which was fueled by monomethylhydrazine (MMH) and nitrogen tetroxide, containing {{cvt|10000|kg}} of storable propellant. The EPS was subsequently improved for use on the Ariane 5G+, GS, and ES.

The EPS upper stage was capable of repeated ignition, first demonstrated during flight V26 which was launched on 5 October 2007. This was purely to test the engine, and occurred after the payloads had been deployed. The first operational use of restart capability as part of a mission came on 9 March 2008, when two burns were made to deploy the first Automated Transfer Vehicle (ATV) into a circular parking orbit, followed by a third burn after ATV deployment to de-orbit the stage. This procedure was repeated for all subsequent ATV flights.

Ariane 5ECA used the ESC (''Étage Supérieur Cryotechnique'' — Cryogenic Upper Stage), which was fueled by liquid hydrogen and liquid oxygen. The ESC used the HM7B engine previously used in the Ariane 4 third stage. The propellent load of 14.7 tonne allowed the engine to burn for 945 seconds while providing 6.5 tonne of thrust. The ESC provided roll control during powered flight and full attitude control during payload separation using hydrogen gas thrusters. Oxygen gas thrusters allowed longitudinal acceleration after engine cutoff. The flight assembly included the Vehicle Equipment Bay, with flight electronics for the entire rocket, and the payload interface and structural support.<ref>European Space Agency, "Ariane 5ECA": http://www.esa.int/Enabling_Support/Space_Transportation/Launch_vehicles/Ariane_5_ECA2 Discussed in context of other launch vehicles in Gérard Maral, Michel Bousquet, and Zhili Sun, ''Satellite Communications Systems: Systems, Techniques and Technology'', sixth edition, London: Wiley, 2020 {{ISBN|9781119382072}}</ref><ref>{{Cite web |title=ESC-A – Cryogenic upper stage |url=https://www.arianespace.com/?popup=ariane-5-4 |url-status=dead |archive-url=https://web.archive.org/web/20211227172650/https://www.arianespace.com/?popup=ariane-5-4 |archive-date=December 27, 2021 |access-date=December 27, 2021 |website=Arianespace}}</ref>

=== Fairing === The payload and all upper stages were covered at launch by a fairing for aerodynamic stability and protection from heating during supersonic flight and acoustic loads. It was jettisoned once sufficient altitude has been reached, typically above {{Convert|100|km|mi nmi|abbr=on}}. It was made by Ruag Space and since flight VA-238 it was composed of 4 panels.<ref>{{cite web|author1=ESA|title=Ariane 5 launch proves reliability and flies new fairing|url=https://www.esa.int/Enabling_Support/Space_Transportation/Ariane_5_launch_proves_reliability_and_flies_new_fairing|access-date=27 February 2020}}</ref>{{clarify|that's fine for explaining what fairings do, generally. But who makes the Ariane fairing? At what cost? What are any of it's design specifications or design characteristics?|date=September 2019}}

=== Launch preparations === With the exception of the solid rocket boosters (for safety and cost reasons), the components were assembled in Europe, and then shipped to French Guyana by boat. Once at Kourou, the components were assembled in the Launcher Integration Building (BIL), then transferred into the Final Assembly Building (BAF) for mating the payload and fairing, before the completed rocket was transferred to the Launch Zone (ZL) for fueling and launch.<ref>{{cite web |url=https://arc.aiaa.org/doi/pdf/10.2514/6.2014-1624 |title=Ariane 5 production and integration operations: ten years of continuous efficiency and quality improvement |date=May 2014 |access-date=November 18, 2025}}</ref>

The new ratio required length modifications to the first-stage tanks. The EPS second stage was replaced by the ESC-A (''Etage Supérieur Cryogénique''-A), which had a dry weight of {{cvt|4540|kg}} and was powered by an HM-7B engine burning {{cvt|14900|kg}} of cryogenic propellant. The ESC-A used the liquid oxygen tank and lower structure from the Ariane 4's H10 third stage, mated to a new liquid hydrogen tank. Additionally, the EAP booster casings were lightened with new welds and carry more propellant. The Ariane 5ECA started with a GTO launch capacity of {{cvt|9100|kg}} for dual payloads or {{cvt|9600|kg}} for a single payload.<ref>{{cite web|url=https://space.skyrocket.de/doc_lau_det/ariane-5eca.htm|title=Ariane-5ECA|publisher=Gunter's Space Page|date=20 February 2020|access-date=23 October 2021}}</ref> Later batches: PB+ and PC, increased the max payload to GTO to {{cvt|11115|kg}}.<ref name=final-10/> The Ariane 5 ECA flew 72 times from 2002 to 2019 with one failure and one partial failure. |- | align="center" | '''ECA+''' |The Ariane 5ECA+ (''Evolution Cryotechnique type A+''), first successfully flown in 2019, used an improved ESC-D (''Etage Supérieur Cryogénique''-D).<ref>{{Cite web |last=Krebs |first=Gunter D. |title=Ariane-5ECA+ |url=https://space.skyrocket.de/doc_lau_det/ariane-5eca-plus.htm |access-date=2024-07-09 |website=Gunter's Space Page |language=en}}</ref> |- | align="center" | '''ES''' | The Ariane 5ES (''Evolution Storable'') had an estimated LEO launch capacity of {{cvt|21000|kg}}.

=== Ariane 5 ME === The Ariane 5 '''ME''' (Mid-life Evolution) was in development into early 2015, and was seen as a stopgap between Ariane 5ECA/Ariane 5ES and the new Ariane 6. With first flight planned for 2018, it would have become ESA's principal launcher until the arrival of the new Ariane 6 version. ESA halted funding for the development of Ariane 5ME in late 2014 to prioritize development of Ariane 6.<ref name=slr20141203/>

The Ariane 5ME was to use a new upper stage, with increased propellant volume, powered by the new Vinci engine. Unlike the HM-7B engine, it was to be able to restart several times, allowing for complex orbital maneuvers such as insertion of two satellites into different orbits, direct insertion into geosynchronous orbit, planetary exploration missions, and guaranteed upper stage deorbiting or insertion into graveyard orbit.<ref name="AdaptedME">{{cite web|url=http://www.esa.int/Our_Activities/Launchers/Launch_vehicles/Adapted_Ariane_5_ME|title=ESA – Adapted Ariane 5ME|access-date=23 July 2014|archive-url=https://web.archive.org/web/20141006114600/http://www.esa.int/Our_Activities/Launchers/Launch_vehicles/Adapted_Ariane_5_ME|archive-date=6 October 2014|url-status=live}}</ref><ref name=sfn-20121121/> The launcher was also to include a lengthened fairing up to {{cvt|20|m}} and a new dual launch system to accommodate larger satellites. Compared to an Ariane 5ECA model, the payload to GTO was to increase by 15% to {{cvt|11500|kg}} and the cost-per-kilogram of each launch was projected to decline by 20%.<ref name="AdaptedME"/>

==== Development ==== Originally known as the Ariane 5'''ECB''', Ariane 5ME was to have its first flight in 2006. However, the failure of the first ECA flight in 2002, combined with a deteriorating satellite industry, caused ESA to cancel development in 2003.<ref>{{cite web|url=http://www.flightglobal.com/news/articles/esa-cancels-plans-for-uprated-ariane-5-ecb-160882/|title=ESA cancels plans for uprated Ariane 5 ECB|access-date=27 April 2012|archive-url=https://web.archive.org/web/20130730171835/http://www.flightglobal.com/news/articles/esa-cancels-plans-for-uprated-ariane-5-ecb-160882/|archive-date=30 July 2013|url-status=live}}</ref> Development of the Vinci engine continued, though at a lower pace.

On 21 November 2012, ESA agreed to continue with the Ariane 5ME to meet the challenge of lower priced competitors. It was agreed the Vinci upper stage would also be used as the second stage of a new Ariane 6, and further commonality would be sought.<ref name=sfn-20121121/> Ariane 5ME qualification flight was scheduled for mid-2018, followed by gradual introduction into service.<ref name="AdaptedME"/>

On 2 December 2014, ESA decided to stop funding the development of Ariane 5ME and instead focus on Ariane 6, which was expected to have a lower cost per launch and allow more flexibility in the payloads (using two or four P120C solid boosters depending on total payload mass).<ref name=slr20141203>{{cite web|url=http://www.spacelaunchreport.com/ariane6.html|title=Ariane 6|publisher=Space Launch Report|first1=Ed |last1=Kyle|date=3 December 2014|access-date=17 July 2015|archive-url=https://web.archive.org/web/20150530225452/http://www.spacelaunchreport.com/ariane6.html|archive-date=30 May 2015|url-status=usurped}}</ref>

=== Solid propellant stage === Work on the Ariane 5 EAP motors was continued in the Vega programme. The Vega 1st stage engine – the P80 engine – was a shorter derivation of the EAP.<ref name="ESPPhandbook">{{cite book|title=European Space Policy and Programs Handbook|first1=Usa Ibp|last1=Usa|publisher=Int'l Business Publications|year=2010|isbn=9781433015328|page=29}}</ref> The P80 booster casing was made of filament wound graphite epoxy, much lighter than the current stainless steel casing. A new composite steerable nozzle was developed while new thermal insulation material and a narrower throat improved the expansion ratio and subsequently the overall performance. Additionally, the nozzle had electromechanical actuators which replaced the heavier hydraulic ones used for thrust vector control.

These developments could maybe have made their way back into the Ariane programme, but this was most likely an inference based on early blueprints of the Ariane 6 having a central P80 booster and 2-4 around the main one.<ref name="sfn-20121121">{{cite news |author=Clark |first=Stephen |date=21 November 2012 |title=European ministers decide to stick with Ariane 5, for now |url=http://spaceflightnow.com/news/n1211/21ariane/ |url-status=live |archive-url=https://web.archive.org/web/20121127202631/http://spaceflightnow.com/news/n1211/21ariane/ |archive-date=27 November 2012 |access-date=22 November 2012 |publisher=Spaceflight Now}}</ref><ref>{{cite web |url=http://www.esa.int/esaCP/SEMTHGD4VUE_Expanding_0.html|title=Successful firing of Vega's first-stage motor in Kourou|date=30 November 2006|publisher=ESA|access-date=30 December 2007|archive-url=https://web.archive.org/web/20120305173010/http://www.esa.int/esaCP/SEMTHGD4VUE_Expanding_0.html|archive-date=5 March 2012|url-status=live}}</ref> The incorporation of the ESC-B with the improvements to the solid motor casing and an uprated Vulcain engine would have delivered {{cvt|27000|kg}} to LEO.

Ariane 5's first test flight (Ariane 5 Flight 501) on 4 June 1996 failed, with the rocket self-destructing 37 seconds after launch because of a malfunction in the control software.<ref>{{cite magazine |url=https://www.wired.com/2005/11/historys-worst-software-bugs/|magazine=Wired|title=History's Worst Software Bugs|access-date=3 September 2009|last1=Garfinkel|first1=Simson}}</ref> A data conversion from 64-bit floating-point value to 16-bit signed integer value to be stored in a variable representing horizontal bias caused a processor trap (operand error)<ref name="esamultimedia.esa.int"/> because the floating-point value was too large to be represented by a 16-bit signed integer. The software had been written for the Ariane 4 where efficiency considerations (the computer running the software had an 80% maximum workload requirement<ref name="esamultimedia.esa.int"/>) led to four variables being protected with a handler while three others, including the horizontal bias variable, were left unprotected because it was thought that they were "physically limited or that there was a large margin of safety".<ref name="esamultimedia.esa.int"/> The software, written in Ada, was included in the Ariane 5 through the reuse of an entire Ariane 4 subsystem despite the fact that the particular software containing the bug, which was just a part of the subsystem, was not required by the Ariane 5 because it has a different preparation sequence than the Ariane 4.<ref name="esamultimedia.esa.int"/>

The second test flight (L502, on 30 October 1997) was a partial failure. The Vulcain nozzle caused a roll problem, leading to premature shutdown of the core stage. The upper stage operated successfully, but it could not reach the intended orbit. A subsequent test flight (L503, on 21 October 1998) proved successful and the first commercial launch (L504) occurred on 10 December 1999 with the launch of the XMM-Newton X-ray observatory satellite.<ref>{{cite web|title=X-ray Satellite XMM-Newton Celebrates 20 Years in Space|date=December 10, 2019|url=https://www.nasa.gov/feature/goddard/2019/x-ray-satellite-xmm-newton-celebrates-20-years-in-space|publisher=NASA|access-date=March 27, 2023}}</ref>

Another partial failure occurred on 12 July 2001, with the delivery of two satellites into an incorrect orbit, at only half the height of the intended GTO. The ESA Artemis telecommunications satellite was able to reach its intended orbit on 31 January 2003, through the use of its experimental ion propulsion system.

The next launch did not occur until 1 March 2002, when the Envisat environmental satellite successfully reached an orbit of {{cvt|800|km}} above the Earth in the 11th launch. At {{cvt|8111|kg}}, it was the heaviest single payload until the launch of the first ATV on 9 March 2008, at {{cvt|19360|kg}}.

The first launch of the ECA variant on 11 December 2002 ended in failure when a main booster problem caused the rocket to veer off-course, forcing its self-destruction three minutes into the flight. Its payload of two communications satellites (STENTOR and Hot Bird 7), valued at about €630 million, was lost in the Atlantic Ocean. The fault was determined to have been caused by a leak in coolant pipes allowing the nozzle to overheat. After this failure, Arianespace SA delayed the expected January 2003 launch for the Rosetta mission to 26 February 2004, but this was again delayed to early March 2004 due to a minor fault in the foam that protects the cryogenic tanks on the Ariane 5. The failure of the first ECA launch was the last failure of an Ariane 5 until flight 241 in January 2018.

On 27 September 2003, the last Ariane 5G boosted three satellites (including the first European lunar probe, SMART-1), in Flight 162. On 18 July 2004, an Ariane 5G+ boosted what was at the time the heaviest telecommunication satellite ever, Anik F2, weighing almost {{cvt|6000|kg}}.

The first successful launch of the Ariane 5ECA took place on 12 February 2005. The payload consisted of the XTAR-EUR military communications satellite, a 'SLOSHSAT' small scientific satellite and a MaqSat B2 payload simulator. The launch had been scheduled for October 2004, but additional testing and a military launch (of a Helios 2A observation satellite) delayed the attempt.

On 11 August 2005, the first Ariane 5GS (featuring the Ariane 5ECA's improved solid motors) boosted Thaicom 4, the heaviest telecommunications satellite to date at {{cvt|6505|kg}},<ref>{{cite web |url=https://space.skyrocket.de/doc_sdat/ipstar-1.htm|title=iPStar 1 (Thaicom 4, MEASAT 5, Synertone 1)|publisher=Gunter's Space Page|date=6 February 2018|access-date=23 October 2021}}</ref> into orbit.

On 16 November 2005, the third Ariane 5ECA launch (the second successful ECA launch) took place. It carried a dual payload consisting of Spaceway F2 for DirecTV and Telkom-2 for PT Telekomunikasi of Indonesia. This was the launch vehicle's heaviest dual payload to date, at more than {{cvt|8000|kg}}.

On 27 May 2006, an Ariane 5ECA launch vehicle set a new commercial payload lifting record of {{cvt|8200|kg}}. The dual-payload consisted of the Thaicom 5 and Satmex 6 satellites.<ref>{{cite news|url=http://news.bbc.co.uk/1/hi/sci/tech/5024352.stm|title=Ariane lifts record dual payload|date=27 May 2006|publisher=BBC News|access-date=28 May 2006|archive-url=https://web.archive.org/web/20060926153440/http://news.bbc.co.uk/1/hi/sci/tech/5024352.stm|archive-date=26 September 2006|url-status=live}}</ref>

On 4 May 2007, the Ariane 5ECA set another new commercial record, lifting into transfer orbit the Astra 1L and Galaxy 17 communication satellites with a combined weight of {{cvt|8600|kg}}, and a total payload weight of {{cvt|9400|kg}}.<ref>{{cite web|url=http://www.esa.int/esaCP/SEMOPTU681F_index_0.html|title=Ariane 5 – second launch of six in 2007|date=5 May 2007|publisher=ESA|access-date=6 May 2007 |archive-url=https://web.archive.org/web/20070509043608/http://www.esa.int/esaCP/SEMOPTU681F_index_0.html|archive-date=9 May 2007|url-status=live}}</ref> This record was again broken by another Ariane 5ECA, launching the Skynet 5B and Star One C1 satellites, on 11 November 2007.

On 9 March 2008, the first Ariane 5ES-ATV was launched to deliver the first ATV called ''Jules Verne'' to the International Space Station (ISS). The ATV was the heaviest payload ever launched by a European launch vehicle, providing supplies to the space station with necessary propellant, water, air and dry cargo. This was the first operational Ariane mission which involved an engine restart in the upper stage. The ES-ATV Aestus EPS upper stage was restartable while the ECA HM7-B engine was not.

On 1 July 2009, an Ariane 5ECA launched TerreStar-1 (now EchoStar T1), which was then, at {{cvt|6910|kg}}, the largest and most massive commercial telecommunication satellite ever built at that time<ref>{{cite web|url=http://www.arianespace.com/news-mission-update/2009/604.asp|title=Integration of Ariane 5 is completed for its upcoming heavy-lift launch with TerreStar-1|publisher=Arianespace|date=2 June 2009 |access-date=1 July 2009|archive-url=https://web.archive.org/web/20120223091918/http://www.arianespace.com/news-mission-update/2009/604.asp|archive-date=23 February 2012|url-status=live}}</ref> until being overtaken by Telstar 19 Vantage, at {{cvt|7080|kg}}, launched aboard Falcon 9.
