TheGuiana Space Centre (French:Centre spatial guyanais;CSG), also calledEurope's Spaceport,[3][4] is aspaceport to the northwest ofKourou inFrench Guiana, anoverseas region ofFrance inSouth America. Kourou is located approximately 500 kilometres (310 mi; 270 nmi) north of the equator at a latitude of 5°. In operation since 1968, it is a suitable location for a spaceport because of its nearequatorial location and open sea to the east and north.
At CSG, space launches are conducted by several European private companies and government agencies working together. The CSG land itself is managed byCNES, the French national space agency. The launch infrastructure built on the CSG land is owned by theEuropean Space Agency. The private companyArianespace operates the launches including planning missions, handling customer relationships and overseeing the team at CSG that integrates and prepares vehicles for launch. The rockets themselves are designed and produced by other companies,ArianeGroup for theAriane 6 andAvio for theVega.
In 1964, Guiana was selected to become the spaceport of France,[5][6] replacing France's first launch siteCentre interarmées d'essais d'engins spéciaux inHammaguir (Algeria) after Algeria's independence,[7] moving to and expanding in Guianacolonization.[8] In 1975, France offered to share Kourou with the ESA, with ESA covering today two thirds of Guiana Space Centre's budget.[5][6] Commercial launches are also bought by non-European companies. ESA pays two-thirds of the spaceport's annual budget and has also financed the upgrades made during the development of theAriane launchers.
On 4 April 2017, the center was occupied by 30 labour unions andindigenous peoples leaders in the midst of the2017 social unrest in French Guiana. The center resumed operation on 24 April 2017, after an emergency relief plan of up to 2.1 billion euros was authorized by the French government.[9][10]
The location of the space centre was selected based on various factors. One of the primary benefits of this spaceport is its proximity to theequator, which makes it more efficient, requiring substantially less energy, to launch spacecraft into annear-equatorial,geostationary orbit compared to launching from spaceports at higherlatitudes.
Additionally, the centre's location adjacent to the open sea to the east reduces the potential risk of rocket stages and debris from launch failures falling on or near human settlements, which enhances safety during spaceflight activities.
Furthermore, rockets typically launch towards the east to take advantage ofEarth's rotation and theangular momentum it provides. The near-equatorial location of the Guiana Space Centre offers an advantage for launches to low-inclination or geostationary Earth orbits, as rockets can be launched into orbits with an inclination of as low as 6°. In contrast, a rocket launched fromCape Canaveral Space Force Station, with a latitude of 28.5°, can only be launched to an inclination of 28.5°, requiring a significant amount of propellant to change the inclination.
The location of the Guiana Space Centre provides benefits for launching spacecraft into low-inclination or geostationary Earth orbits. Rockets of similar size to those used at other spaceports to place satellites intogeostationary transfer orbit (GTO), such as theProton andAriane 5 rockets, can send similar payloads to alow Earth orbit (LEO). For example, the Proton rocket, launched from high latitudes in Russia, can only send 6,270 kg to GTO, while the Kourou-launched Ariane 5 can send more than 10,000 kg to GTO.[11][12]
In 1969 a launch pad for the Diamant rocket was built. The first launch took place in 1970, which was also the first satellite launch from Kourou. More launches followed, but the pad was decommissioned in 1975.[13]
Beginning 2019 the pad is being reactivated. Multiple companies have announced that they would be using the pad for microlaunchers. Among them areIsar Aerospace,Rocket Factory Augsburg, ArianeGroup,PLD Space,Latitude,HyImpulse and Avio with theirSpectrum,RFA One,Callisto,Themis,Miura 5, Zephyr and SL1 rockets. The pad will then be renamed ELM (French:Ensemble de Lancement Multilanceurs,lit. 'Multi-launcher Launch Complex'). It is likely that PLD space will first use the pad in 2025.[14]
Originally built in the 1960s under the name ofBase Équatoriale duCECLES (English:ELDO Equatorial Base), the pad was designed for theEuropa-II launch vehicle. One Europa-II was launched from the site in 1971, which ended in failure due to a guidance problem, before the program was cancelled.[15]
The pad at Guiana was demolished and subsequently rebuilt as the first launch complex for Ariane as ELA (Ensemble de Lancement Ariane). Redesignated later asELA-1, it was used forAriane 1 andAriane 2 and 3 launches until being retired in 1989.[16]
In November 2001, it was refurbished again for theVega rocket and renamed ELV (Ensemble de Lancement Vega). The first launch was on 13 February 2012.[17]
The ELA-2 pad (Ensemble de Lancement Ariane-2), built in 1986, had been used forAriane 4 launches from 1988 until 2003. Before 1988, although purpose-built forAriane 4, the pad hosted anAriane-2 and twoAriane-3 launches. The complex consisted of two areas: the launcher preparation zone and the launch pad, separated by one kilometre, allowing a launcher to be assembled in the preparation zone while another launch from the pad. A mobile service tower at the launch pad provided a protected environment for payload installation and final preparation of the rocket.[18] Following the retirement of theAriane 4 in favor of theAriane 5, In September 2011, the pad's service tower was demolished using explosives.[19]
ELA-3 (Ensemble de Lancement Ariane-3) was active between 4 June 1996 and 5 July 2023, launching theAriane 5. This facility covers an area of 21 km2 (8.1 sq mi).[20]
In the future the site will be adapted by Avio forVega-E launches.[21]
ELA4 is located along theRoute de l'Espace in the Roche Christine site between the ELA-3 and ELS launch facilities. CNES was responsible for the construction of the Ariane 6 ground segments including the new launch pad. Earthworks on the 150 hectare launch site began at the end of June 2015 and was completed at the start of 2016. Four platforms were levelled to accommodate the launch pad, the liquid oxygen and hydrogen tanks and the assembly building. Civil engineering works on the flame trench and other buildings began in the summer of 2016 and ended in 2019.[22][23] The new launch facility was inaugurated on 28 September 2021 with first flight of the Ariane 6 conducted on 9 July 2024.[24]
ESA has built ELS (Ensemble de Lancement Soyouz) for launching Russian-builtSoyuz-2 rockets. The first Soyuz launch from ELS was postponed several times, but launched on 21 October 2011.[25]
ELS is located on the territory ofSinnamary commune, 27 km (17 mi) from Kourou harbor.[26] It is 10 km (6.2 mi) northwest of the site used for the Ariane 5 launches. Under the terms of the Russo-European joint venture, ESA will augment its own launch vehicle fleet with Soyuz rockets – using them to launch ESA or commercial payloads – and the Russians will get access to the Kourou spaceport for launching their own payloads with Soyuz rockets. Russia will use the Guiana Space Centre in addition toBaikonur Cosmodrome. The Guiana location has the significant benefit of greatly increased payload capability, owing to the nearequatorial position. A Soyuz rocket with a 1.7 tones to geostationary transfer orbit performance from Baikonur will increase its payload potential to 2.8 tones from the Guiana launch site.[27]
The ELS project is being co-funded by Arianespace, ESA, and theEuropean Union, with CNES being the prime contractor. The project has a projected cost of approximately €320 million, where €120 million are allocated for modernizing the Soyuz vehicle.[28] The official opening of the launch site construction occurred on 27 February 2007.
On 13 September 2010, Spaceflight Now reported that after several delays in the construction of a mobile gantry the launch pad had been finished, and the first flight of the Soyuz was expected to occur in early 2011.[29] By October 2010, 18 launch contracts were signed. Arianespace has ordered 24 launchers from Russian industry.[30]
On 21 October 2011, twoGalileo IOV-1 and IOV-2 satellites were launched using a Soyuz-ST rocket, in the "first Russian Soyuz vehicle ever launched from Europe's Spaceport in French Guiana.".[31]
On 26 February 2022,Roscosmos announced that it was suspending operations at ELS as a reaction tointernational sanctions during the Russo-Ukrainian War.[32] According toStephane Israël, CEO of Arianespace, "there will no longer be Soyuz launches" from the Guiana Space Center.[2]
In April 2024 CNES put out a call to take over the launch pad. In September the same yearMaiaSpace was chosen to use the pad for their two-stageMaia rocket. The company want to invest tens of millions of euros and aims for an inaugural launch in late 2025. ESA retains a right to select another company of their European Launch Challenge to also use the pad.[33]
Astrium assembles each Ariane 5 launcher in the Launcher Integration Building. The vehicle is then delivered to the Final Assembly Building for payload integration by Arianespace.[34] The Final Assembly Building is located 2.8 km (1.7 mi) from the ELA-3 launch zone. The mobile launch table completes the trip with an Ariane 5 in about one hour. It is then secured in place over the launch pad's flame ducts.[35]

Fire safety is ensured by a detachment of theParis Fire Brigade, a branch of theFrench Army. Security around the base is ensured byFrench Gendarmerie forces, assisted by the3rd Foreign Infantry Regiment of theFrench Foreign Legion.[citation needed] Before and during launch windows, CSG facility security is significantly enhanced by anti-personnel and anti-aircraft measures, the exact configurations of which are classified by the French military. All entrants to the launch complex are also subject to checks for proof of permission to enter the facility.[citation needed]
The Guiana Space Centre (as per CNES) also contains theÎles du Salut, a former penal colony including the infamousDevil's Island. Now a tourist site, the islands are under the launching trajectory forgeosynchronous orbit and have to be evacuated during launches.
As of 2017[update], Kourou counts amongst the spaceports with the highest percentage of successful launches, both successive and overall. Here is a chronology of all orbital launches from the Kourou spaceport since 1970, under the French and European space programmes.
Success Failure Partial Failure Scheduled
The space sector was responsible for about 15% of French Guiana's GDP in 2014, around half of the 28% it was in 1990. This reduction is mostly due to expansion in other sectors, rather than decreasing space activity. As of 2020, the space sector employed 4,620 people in Guiana, meaning the industry was responsible for just under 10% of salaried jobs in the overseas department,[55] though there are estimates that as many as 9,000 people are employed directly and indirectly as a result of activities at the spaceport.[56] The Guiana Space Centre (or CSG) is one of the spaceports in the world that receives the most traffic, and it receives large amounts of funding from the European Space Agency (ESA), with the organisation covering around 66% of the spaceport's annual budget, as well as financing new facilities.[57] Indigenous and local activist groups argue that mainland France is only interested in French Guiana as far as the space centre is concerned, and the funding that the space centre receives is symbolic given the inequity in living standards seen between the department and mainland France.[58][59] For example, despite there being high poverty levels and unemployment rates of over 20% in the department, the cost of living remains high due to a dependence on mainland France for imported food and resources, yet large amounts of funding are invested in the space programme, rather than in public services for the department.[60]
The department became the site of strikes and protests throughout March and April 2017, which were held to highlight the insecurity and infrastructural issues facing French Guiana. Alongside 30 labour unions who launched strikes, the Collective of 500 Brothers led protests in Kourou, which spread across the entire country, and resonated in mainland France.[61][62] On 21 March 2017, the launch of an Ariane 5 rocket carrying a Brazilian satellite and a South Korean satellite was prevented due to protesters and workers on strike from the CSG blockading the centre.[63] Further strikes and occupation of the space centre meant that the satellites were not launched until May 2017.[64] Negotiations between the French government and Guianese protesters resulted in a rejection of a €1.1 billion offer made by the French, with the Guianese demanding at least €3 billion in aid.[59] Since the protests, CNES (National Centre for Space Studies), the French government space agency that operates the spaceport, added an additional €10 million to the €40 million it had already pledged to fund economic and social programmes in French Guiana.[56]
Space launches have increased aluminium concentrations around the site.[65]
Particularly regarding the colonial history the site has been identified as carrying a heritage ofcolonialism andimperialisminto space.[66][67]
