Guiana Space Centre


The Guiana Space Centre is a French and European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Operational since 1968, it is particularly suitable as a location for a spaceport. It fulfills the two major geographical requirements of such a site:
The European Space Agency, the French space agency CNES, and the commercial companies Arianespace and Azercosmos conduct launches from Kourou. This was the spaceport used by the ESA to send supplies to the International Space Station using the Automated Transfer Vehicle.

History

The location was selected in 1964 to become the spaceport of France.
In 1975, France offered to share Kourou with ESA. Commercial launches are bought also 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 the Ariane launchers.
On 4 April 2017, the centre was occupied by 30 labour union leaders in the midst of the 2017 social unrest in French Guiana, but was taken back on 24 April 2017.

Facilities

Kourou is located approximately north of the equator, at a latitude of 5°. It is a common misconception that the main advantage of launching a rocket from the equator is the extra boost provided by the speed of the Earth's rotation. For example, the eastward boost provided by the Earth's rotation is about at the Guiana Space Centre, as compared to about at the United States east coast Cape Canaveral and Kennedy Space Center spaceports which are at 28°27′N latitude in Florida. This means that rockets need around 60 m/s more delta-v to reach Low Earth Orbit from Cape Canaveral, which is an insignificant disadvantage.
In reality, the main benefit of Kourou is that the near-equatorial launch location provides an advantage for launches to low-inclination Earth orbits compared to launches from spaceports at higher latitude. This is because rockets can be launched into orbits with an inclination of as low as ~6°. The lowest inclination a rocket from Cape Canaveral could be launched to is 28.5°. Inclination change burns already require significant amounts of delta-v, so needing to change inclination by 28.5° seriously affects a rocket's capability to send satellites into a geostationary transfer orbit. As a result of these phenomena, similarly sized Proton and Ariane 5 rockets can send similar payloads to LEO. However, the Proton, launched from high latitudes in Russia, can only send 6,270 kg to GTO while a Kourou-launched Ariane 5 can send more than 10,000 kg to GTO.

BEC / ELA-1 / ELV

Originally built in the 1960s under the name of Base Équatoriale du CECLES, the pad located at was designed for the Europa-II rocket. One Europa-II was launched from the site, before the programme was cancelled.
The pad was demolished, and subsequently rebuilt as the first launch complex for Ariane rockets. Renamed ELA, it was used for Ariane 1 and Ariane 2 and 3 launches until being retired in 1989.
In November 2001, it was renamed ELV pad and refurbished again for the Vega rocket. The first launch was performed on 13 February 2012.

ELA-2

The ELA-2 pad, located at had been used for Ariane 4 launches until 2003.

ELA-3

ELA-3 has been active for Ariane 5 launches since 1996. This facility is located at and covers an area of.

ELA-4

ELA-4 is presently under construction, intended for future Ariane 6 launches. This facility is located at.

ELS / Soyuz at CSG

ESA has built ELS at for launching Russian-built Soyuz-2 rockets. The first Soyuz launch from ELS was postponed several times, but launched on October 21, 2011.
ELS is located on the territory of Sinnamary commune, from Kourou harbor. It is north 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 to Baikonur Cosmodrome. The Guiana location has the significant benefit of greatly increased payload capability, owing to the near equatorial position. A Soyuz rocket with a 1.7 tonnes to geostationary transfer orbit performance from Baikonur, will increase its payload potential to 2.8 tonnes from the Guiana launch site.
The ELS project is being co-funded by Arianespace, ESA, and the European 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. The official opening of the launch site construction occurred on 27 February 2007. Excavation work however, had previously begun several months beforehand.
On September 13, 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. By October 2010, 18 launch contracts had been signed. Arianespace has ordered 24 launchers from Russian industry.
On October 21, 2011, two Galileo IOV-1 & 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."

Final assembly building

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. The Final Assembly Building is located 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.

Launches

Launch safety

Fire safety is ensured by a detachment of the Paris Fire Brigade, a branch of the French Army. Security around the base is ensured by French Gendarmerie forces, assisted by the 3rd Foreign Infantry Regiment of the French Foreign Legion.
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.
The Guiana Space Centre also contains the Îles du Salut, a former penal colony including the infamous Devil's Island. Now a tourist site, the islands are under the launching trajectory for geosynchronous orbit and have to be evacuated during launches.

Early launches
