Project in brief
Sanctions imposed on Russia by European governments and recent announcements by Roscosmos, the Russian federal space agency, have significantly impacted space cooperation with this former partner.
Within the framework of an intergovernmental agreement, the Guiana Space Centre (CSG) had been accommodating launches of Russia’s Soyuz vehicle since 2011. With the imminent arrival on the market of the new Vega-C and Ariane 6 launchers, a rescheduling of European institutional launches is now envisioned. CNES expedited procedures to enable the quick, safe and orderly departure of Russian engineers and technicians from the launch base. Consequently, the Soyuz in Guiana programme is currently suspended.
21 October 2011, a Soyuz launcher roared off the pad on its first-ever flight from the CSG, carrying aloft two European Galileo satellites. This milestone event marked the culmination of a collaboration initiated in 2003 by the European Space Agency (ESA), Roscosmos and CNES, the initiator of the Soyuz in Guiana programme and owner of the CSG.
Standing 46 metres tall and with a mass of 308 tonnes, Soyuz ST (for Special Tropics) is capable of placing payloads of up to 3.2 tonnes into geostationary transfer orbit (GTO), taking maximum advantage of the ‘slingshot’ effect imparted as a result of the CSG’s near-equatorial position. Built in Russia, Soyuz ST was adapted to the weather conditions in French Guiana and to the base’s range safety regulations. It was commercially operated by European launch services provider Arianespace.
Between 2011 and 2018, 20 Soyuz launchers lifted off from the purpose-built launch complex constructed by CNES in the municipality of Sinnamary.
CNES’s role
CNES was the initiator of the Soyuz in Guiana programme and is the owner of the CSG.
