Two Galileo Satellites To Be Boosted Into Orbit From French Guiana
The launcher for this week’s Arianespace Soyuz mission is ready for its September 10 liftoff, having been “topped off” with the payload of two European Galileo satellites at the Spaceport.
This will be the 12th mission from French Guiana for Arianespace’s medium-lift workhorse, as well as the company’s eighth flight in 2015 with its complete launcher family – which also includes the heavy-lift Ariane 5 and lightweight Vega.
During a busy day of activity Tuesday, the basic three-stage Soyuz was first rolled out to the launch zone in the Spaceport’s northwestern sector near the city of Sinnamary, followed by its raising to the vertical position and suspension over the launch pad – held in place by four large support arms.
After the 174-foot-tall mobile gantry was moved in to protect the launcher, this mission’s “upper composite” (composed of the Fregat upper stage, the two dispenser-mounted Galileo satellites and payload fairing) was hoisted and mated atop Soyuz.
Arianespace’s September 10 mission will be the fifth Soyuz flight with Galileo satellites performed from French Guiana – a series that began with the Russian-built launcher’s inaugural liftoff at the Spaceport in October 2011.
RKTs-Progress (the Samara Space Center) is responsible for the design, development and manufacture of Soyuz’ three lower stages and payload fairing, as well as for integrating the launch vehicle stages and handling flight operations. The Fregat upper stage is manufactured by NPO Lavochkinn
The passengers for this Thursday’s Flight VS12 are the fifth and sixth FOC (Full Operational Capability) spacecraft in Europe’s Galileo navigation program. They were built by OHB System, with their navigation payloads supplied by Surrey Satellite Technology Ltd.
