Introduction

– European launcher strategy is founded on the principle of a guaranteed access to space. Soyuz, a medium-class launcher whose performance perfectly complements that of ESA’s developed launchers, Ariane 5 and Vega, shall contribute to the competitiveness and flexibility of the exploitation of the launchers operated by Arianespace from the CSG, Europe’s spaceport.

– From the international cooperation perspective, Soyuz at the CSG constitutes a milestone in the strengthening of the long-term partnership between Europe and the Federation of Russia in the field of launchers.

– The Soyuz at the CSG programme covers the construction of the Soyuz launch complex at the CSG and the adaptation of the Soyuz launcher for its exploitation from the CSG. In addition, the programme covers activities related to the development of a new version of the Soyuz launcher, the Soyuz 2-1b.

– To ensure that Soyuz would be able to carry out manned missions from CSG, a detailed study was performed and the new launch complex infrastructure was designed so that it can be smoothly adapted for human spaceflight, as and when such decision is taken.

– Soyuz at the CSG is implemented in the form of an ESA optional programme. The overall cost of the execution, amounting to €467.9 million at 2002 e.c., is shared between 7 ESA Participating States (€341.9 million), Arianespace (€121 million) and the European Union that contributes the remaining part.

Programme organisation

During the development phase:– ESA, as procuring entity for which the Soyuz at the CSG launch system (i.e. an adapted

launcher and the related launch complex) is developed, leads such system development and concludes with the prime contractor the development contract.

– CNES, the French Space Agency, is the system architect and prime contractor. As system architect, CNES is responsible for ensuring the overall coherence of the design requirements with regard to the CSG launch range. In addition, CNES is also the entity entrusted by the French Government with a safety and security mission consisting in the control of the technical risks associated with the preparations for and the conduct of launches from the CSG.

– Arianespace, under CNES contract, is responsible for the procurement of all Russian activities through the Russian Federal Space Agency, which acts as prime supplier.

– Roscosmos, the Russian Federal Space Agency, is responsible for all Russian activities and is the qualification authority for the launcher system. The main Russian industrial partners include: TsSKB, Soyuz general designer; NPO Lavotchkine, Fregat upper stage designer; and TsENKI-NIISK, ground segment general designer.

During the exploitation phase:– Arianespace, in his role of launch service provider, is the entity responsible for the

exploitation of launchers operated from the CSG, under terms and conditions defined in specific arrangements concluded with ESA.

CSG, Europe’s spaceport

– European launchers lift off from the CSG, Kourou, in French Guiana. The CSG origins date back to the 1960s. In 1964 the French Government chose Kourou, out of 14 other sites, as a base from which to launch its satellites. The CSG is operational since 1968.

– When ESA came into being in 1975, the French Government offered to share the CSG with ESA. For its part, ESA approved funding to prepare the spaceport for the Ariane launchers under development. Since then, ESA has continued to support the investments required to maintain the top level services provided by the spaceport and to finance new facilities. ESA owns the infrastructure for the Ariane 5, Vega and Soyuz launches. The Ariane 5 launch complex is operational since 1996.

– The CSG lies at latitude 5°3', just over 500 km north of the equator, and it offers a launch angle of 102°, thus enabling a wide range of missions from east to north. Furthermore, there is no significant risk of cyclones or earthquakes. Because of its ideal situation, it allows to carry out all possible missions.

– Due to the geographic location, Soyuz from the CSG will have improved performance (+50%) and will be able to place up to 3 tonnes into geostationary transfer orbit, when compared to the 2 tonnes that can be launched from Baikonur in Kazakhstan.

Launcher adaptation

– Two different versions of the upgraded Soyuz-ST launcher shall be operated by Arianespace from the CSG: the Soyuz-2-1a and the Soyuz-2-1b. Both versions are fitted with a restartable Fregat upper stage and an enlarged ST fairing (4.1-m diameter and 11.4-m length) thus offering improved mission flexibility. On top of that, the Soyuz-2-1b configuration introduces an upgraded third stage engine, which significantly increases (+12%) the launcher’s overall performance.

– The adaptation of the Soyuz launcher for its exploitation at the CSG includes measures to preserve the overall coherence within the launch range, to conform to the safeguard regulations in force and to accommodate to French Guiana environmental conditions.

– S-band antennas and receivers so as to adapt to the telemetry wavebands already used for Ariane 5.

– A European Safeguard Kit (KSE) that implements the European neutralization chain, in coherence with that used for Ariane 5.

– The boosters are adapted to sink after separation and splash-down in the ocean, as opposed to launches from Plesetsk in Russia or Baikonur in Kazakhstan.

– The first two Soyuz-2-1a launchers and the first two Soyuz-2-1b launchers arrived in French Guiana in November 2009 and in June 2011, respectively.

Soyuz launch complex

The decision on the location took into consideration a number of parameters (among which the availability of a homogeneous granitic ground) as well as operational, flight safeguard and security considerations. 13 km NW of the Ariane 5 launch complex, the ELS comprises:

1.The launch zone, with its 5-level launch platform, is almost identical to the other Soyuz launch sites in Plesetsk or Baikonur. The most visible difference is a mobile gantry (as opposed to a fix tower), which provides a protected environment as at CSG payloads are installed on the launcher vertically.

2.The preparation and integration building (MIK), where all stages are prepared and Soyuz is assembled horizontally. The MIK and the launch zone are linked by a railway allowing the transfer of the launcher to its launch pad.

3.The launch control centre (CDL), which houses the European and Russian monitoring and remote control systems as well as the teams in charge of the final operations before the launch.

Soyuz launch complex

– ELS foundation stone was laid in February 2007, although preliminary civil works had started in 2004. With the acceptance review of the European infrastructure in October 2008, the assets were formally delivered to ESA and subsequently handed over to CNES for technical qualification.

– The first Russian-built equipment and Russian staff arrived in French Guiana in mid-2008 to undertake the assembling of the launch table, mobile gantry, fuelling systems and test benches. In that same year, the manufacturing of the beams of the mobile gantry’s metallic structure was initiated.

– Technical and organizational issues delayed the arrival in French Guiana of the first elements of the mobile gantry’s structure until the last quarter of 2009 –with a significant impact in the programme planning. After completion of the structure assembly in the first half of 2010, integration of European systems could finally start in June of the same year, and provisional acceptance of the equipped mobile gantry was pronounced in the end of March 2011.

Technical qualification

– Leaded by CNES, and performed along with its European and Russian partners, the technical qualification started in May 2010. It was composed of a number of test campaigns, which thoroughly covered all mechanical, fluid, propellant, utility and mobile gantry systems, in view of demonstrating their conformity to the specified functionality.

– The acceptance review took place from 28 to 30 March 2011, and concluded with the declaration by ESA, upon CNES proposal, of the technical qualification of the ELS, by which CNES formally delivered the facilities and the qualification file to ESA.

– For its part, ESA formally handed the ELS over to Arianespace on 31 March 2011, thus marking the start of the operational qualification phase.

Operational qualification

– Leaded by Arianespace, and performed along with its European and Russian partners, the operational qualification started in April 2010. A launch rehearsal ensured that the launcher and the new launch complex facilities worked together perfectly, and trained the operational teams under realistic launch campaign conditions, including:

• the preparation of the launcher and Fregat stages in the MIK

• the integration of the upper composite in the S3B preparation building

• the launcher’s transfer to the launch zone, its erection into the vertical position and its installation on the pad

• the upper composite’s transfer to the launch zone, and its hoisting onto the top of the launcher

• the testing of ground and launcher interfaces, including those in connection with the launch range and downrange stations

– The acceptance review took place on 15 and 16 June 2011.

Qualification of the launch system and preparation of the first launch

– According to the rationale established by the programme management rules, the qualification of the Soyuz at the CSG launch system is to be declared in two stages:

1. A first stage, before the first launch, by which it is authorized the transfer of the launcher and upper composite to the launch zone to proceed to the final operations and launch. Qualification Commission n. 1 is scheduled in the beginning of September 2011.

2. A second stage, after the first launch and the exploitation of the associated data, by which it is authorized the final handover of the Soyuz launch complex to Arianespace, in his role of launch service provider, thus marking the start of the exploitation phase.

– The launch campaign is scheduled to develop as of August 2011 for a first launch in the third quarter of the year. The current target is to have a first launch on 20 October 2011 placing two IOV Galileo satellites on their operational orbit.

– A specific working group involving Russian party, Arianespace, CNES an ESA is performing a complete final check-out of the last sensitive topics related to safeguard. Final conclusions are expected to be delivered by the end of August 2011.
