Galileo's Fregat is transferred at the Spaceport after its fueling in the purpose-built FCube (Fregat Fueling Facility) facility for Arianesapce's Soyuz Flight VS15, scheduled for 24 May.The Fregat was transferred by road to the Spaceport’s S3B clean room. At this facility, the upper stage will be integrated with passengers for this month’s Soyuz mission: the latest two Galileo Full Operational Capability (FOC) spacecraft for Europe’s satellite-based navigation system. This will create the 'upper composite', which is protected by a payload fairing during the initial phase of flight through the atmosphere.
