Soyuz

The decision to develop the launch infrastructure to enable Soyuz to be launched from French Guiana was of mutual interest to both Europe and Russia, and benefited from funding from the European Community.
 
Soyuz is a medium-class launcher. Its performance perfectly complemented that of the ESA launchers Ariane and Vega, and increased the competitiveness and flexibility of the exploitation of Ariane launchers in the commercial market.
 
The Soyuz launch vehicle that was used at Europe’s Spaceport is the Soyuz-2 version called Soyuz-ST. This included the Fregat upper stage and the ST fairing. Soyuz-2 was the most recent version of the renowned family of Russian launchers that began the space race more than 50 years ago by launching Sputnik, the first satellite placed in orbit, and then sending the first man into space.
 
Soyuz-2 had improved performance and carried up to 3 tonnes into geostationary transfer orbit, compared to the 1.7 tonnes that can be launched from Baikonur, in Kazakhstan.

Soyuz launch site

Geological and topographic surveys began at the site selected for Soyuz in 2003. The site, called ELS, is 13 km northwest of the Ariane launch site and consists of three main zones: the launch platform, the preparation area (MIK), where the three stages are assembled horizontally and checked, and the launch control centre.
 
Construction of the flame trench, the launch platform, the MIK and the control centre was completed at the end of 2008. The MIK connected to the launch platform by a 700-metre railway, which was used to transport the launcher in a horizontal position. The launch control centre was one kilometre from the launch pad.

Human spaceflight

The Soyuz rocket is the workhorse for Russian human space missions and has been used for that purpose longer than any other vehicle. In the 1960s it began carrying cosmonauts into space and then to the Soviet Salyut and Mir stations. Together with the US Space Shuttle, it ensured the transport of crews to and from the International Space Station.
 
To ensure that Soyuz was able to carry out missions of this type from Europe’s Spaceport, the launch infrastructure was designed so that it could be smoothly adapted for human spaceflight, should this have been decided.
