Guiana Space Centre. It is a major European spaceport located on the northeastern coast of South America in the French overseas department of French Guiana. Operated by the Centre National d'Études Spatiales (CNES), Arianespace, and the European Space Agency (ESA), it is the primary launch site for European space missions. Its location near the Equator provides a significant advantage for launching satellites into geostationary orbit.

History

The site was selected by the French government in 1964, with construction beginning under the authority of the Centre National d’Études Spatiales. The first orbital launch occurred in 1970 with the Véronique sounding rocket. The facility's importance grew substantially with the establishment of the European Space Agency in 1975 and the subsequent development of the Ariane rocket program. The first Ariane 1 launch from the site took place in 1979, marking the beginning of Europe's independent access to space. Major expansions have included the construction of launch complexes for the Ariane 5, Soyuz-2, and Vega launch vehicles, solidifying its role as a cornerstone of European space policy.

Facilities

The spaceport encompasses a vast area and features several key installations. The main launch complexes are ELA-3 for the Ariane 5 and its successor Ariane 6, ELS for the Soyuz-2 rocket operated by Arianespace, and ELV for the Vega light launcher. Support infrastructure includes payload preparation buildings, solid and liquid propellant storage facilities, a dedicated Eurockot integration hall, and the Jupiter Control Room. The site also hosts tracking stations, such as those used by the Centre National d’Études Spatiales and the European Space Operations Centre (ESOC), for monitoring launches and satellite telemetry.

Launch operations

It is one of the world's busiest spaceports, conducting numerous missions annually for commercial, scientific, and governmental clients. Primary launch vehicles are the heavy-lift Ariane 5, the medium-lift Soyuz-2, and the small-lift Vega, covering a full spectrum of payload requirements. Notable missions launched from here include the James Webb Space Telescope, the Automated Transfer Vehicle for the International Space Station, the BepiColombo mission to Mercury, and countless commercial satellites for operators like Eutelsat, Inmarsat, and SES S.A.. Launches are managed by the industrial prime contractor Arianespace.

Role in international space programs

The facility serves as the operational backbone for the European Space Agency's launcher programs and is a hub of international cooperation. The European Union relies on it for launching its Galileo navigation satellites. Through partnerships, it also launches missions for NASA, JAXA, and the Canadian Space Agency. The presence of the Soyuz-2 program, a result of a strategic agreement between ESA and Roscosmos, further underscores its international character. It is a key asset for the European Union Space Programme and supports the ambitions of the European Defence Agency.

Geography and climate

Situated on the Atlantic coast near the town of Kourou, its geographical position at approximately 5 degrees north latitude is its principal asset. This location allows rockets to benefit from the Earth’s rotational velocity, significantly increasing payload mass to geostationary transfer orbit compared to launch sites at higher latitudes. The region features a tropical rainforest climate with consistent temperatures and distinct wet and dry seasons. The coastal location provides a clear launch azimuth over the Atlantic Ocean, enhancing safety for downrange stages and debris.

Security and environmental considerations

The site is located within a secured perimeter managed by the French Armed Forces, including the French Foreign Legion based at the 3rd Foreign Infantry Regiment in nearby Kourou. Environmental monitoring is conducted by the Centre National d’Études Spatiales to minimize the impact of launch activities on the surrounding Amazon rainforest and coastal ecosystems. Programs are in place to protect local fauna, including sea turtles on adjacent beaches like Plages des Roches. The facility adheres to strict regulations aligned with French Guiana's environmental code and international treaties.
