Overview
The Guiana Space Centre (Centre Spatial Guyanais, CSG) is Europe's spaceport, located near Kourou in French Guiana on the northeastern coast of South America. At just 5.2°N latitude — closer to the equator than any other major launch site — CSG provides the best possible orbital mechanics advantage for geostationary orbit (GEO) launches. The facility is operated by CNES (the French space agency) on behalf of ESA and the European Commission.

Why the Equator?
Kourou's near-equatorial location provides a ~465 m/s velocity bonus from Earth's rotation — the highest of any operational spaceport. For GEO launches, this is enormously valuable: satellites launched from Kourou need less fuel for the final orbit-raising manoeuvre than those launched from higher latitudes. This translates directly into either heavier payloads or longer satellite operational lifetimes (more fuel reserved for station-keeping). The open Atlantic Ocean to the north and east provides safe downrange trajectory for all orbital inclinations.
Active Launch Pads
ELA-4 (Ariane 6): Purpose-built for the Ariane 6 rocket, Europe's new-generation launcher. ELA-4 is a modern, streamlined pad designed for faster turnaround than the previous Ariane 5 facilities.
SLV (Vega Launch Zone): Pad for the Vega-C light-lift rocket, used for small and medium satellite deployments to LEO and SSO.
ELS (Soyuz Launch Zone): Built for Soyuz launches from Kourou (2011–2022). Operations suspended following Russia's invasion of Ukraine in 2022, when Roscosmos withdrew its personnel.
History
France selected Kourou as its launch site in 1964, replacing the Hammaguir site in Algeria after Algerian independence. The first launch occurred in 1968. When ESA adopted the Ariane programme, CSG became Europe's primary spaceport. Over 250 Ariane launches (1–5 series) have been conducted from Kourou, establishing Europe's independent access to space and dominating the commercial GEO launch market for decades.
