Arianespace has successfully launched the 13th and 14th satellites of the Galileo constellation. The company’s second Soyuz launch of the year took place on May 24 at 5:48 am local time (10:48 UTC) from the Guiana Space Center (CSG) in Kourou, French Guiana.
Today’s Soyuz success marks the 250th launch from the Guiana Space Center with its family of launchers. This total, composed of 229 Ariane flights, 15 with Soyuz and six liftoffs of Vega, confirms Arianespace’s operational performance over time for the benefit of all its clients.
Arianespace’s new Spaceport processing facility has fueled another Fregat stage. This upper stage for the medium-lift Soyuz launcher will be used for the May 24 flight from French Guiana with two European Galileo navigation satellites.
Named the FCube (Fregat Fueling Facility), the purpose-built installation is utilized to “top off” Fregat upper stages during Soyuz launch campaigns at the Spaceport. In service since last year, the FCube supports Arianespace’s sustained launch pace, giving the company greater flexibility in managing its mission manifest, while also increasing launch capacity with Soyuz and its other launch vehicle family members: the heavy-lift Ariane 5 and lightweight Vega.

The first of two Galileo navigation satellites to be orbited on Arianespace’s May 24 Soyuz flight has been integrated on its payload dispenser system, marking a key step as preparations advance for this medium-lift mission from French Guiana.
Named “Danielė”, the spacecraft was installed last week during activity inside the Spaceport’s S3B payload preparation facility. It is to be joined on the dispenser system by the mission’s other passenger, “Alizée”, whose own installation is forthcoming in a side-by-side arrangement.
The pair are then to be mated atop Soyuz’ Fregat upper stage and encapsulated in the protective payload fairing. Prime contractor OHB System in Bremen, Germany produced the satellites, and their onboard payloads are supplied by UK-based Surrey Satellite Technology Limited (SSTL), which is 99-percent owned by Airbus Defence and Space.

Preparations for Arianespace’s upcoming mission have moved into the fueling phase for the two Galileo navigation satellites that will be orbited by a medium-lift Soyuz on 24 May from the Spaceport in French Guiana.
Technicians donned spacesuit-like protective outfits to handle the toxic hydrazine fuel that will enable the two satellites to fine-tune their orbits and orientation over the course of their working lives of 12 years or more.
The 13th Galileo satellite was fuelled on 3 May, with the 14th being fuelled a day later.
After fuelling both satellites have been connected to “checkout terminal equipment” to enable battery charging and atomic clock monitoring. Read more…
This timelapse video shows Galileo satellites 9 and 10, from final preparations to liftoff on a Soyuz rocket from Europe’s Spaceport in Kourou, French Guiana, at 02:08 GMT (04:08 CEST) on 11 September 2015.
On tonight’s launch from the Guiana Space Center, Arianespace will orbit the two latest Galileo satellites. Carried out on behalf of the European Commission, under a European Space Agency (ESA) contract, this launch will orbit the ninth and tenth Galileo FOC satellites.
While waiting for the launch enjoy these pics from the European Space Centre thanks to CNES.
Following liftoff from the Guiana Space Center, the powered phase of the lower three Soyuz stages will last about nine minutes. The third stage of the launcher will then be separated from the upper composite, comprising the Fregat upper stage and the Galileo satellites 9 & 10. The three lower stages and the fairing will fall back into the sea.
After a first burn, the upper composite is spun up during a ballistic phase lasting about 3 hours and 15 minutes. Then, Fregat will ignite its own engine to bring the upper composite to a transfert orbit above the Earth. At a pre-determined point of this orbit, Fregat will ignite a second burn lasting 4 minutes to reach the circular orbit of separation.
At the end of the mission, the Fregat upper stage will be passivated. The Galileo satellites will then lower their altitude in order to reach their operational orbit.
Next we present a couple of recent videos taken in the European Space Centre in Kourou (French Guiana), where the Galileo 9 & 10 Soyuz VS12 launch campaign is explained by Jean-Claude Chiarini (ESA Mission Director) and Thierry Wilmart (Arianespace Mission Director).
Galileo satellites 9 and 10 are scheduled to lift off at 02:08 GMT (04:08 CEST) on 11 September from Europe’s Spaceport.
