Soyuz VS03, the third Soyuz flight from Europe’s Spaceport in French Guiana, was transferred to the launch zone on October 8. The vehicle was rolled out horizontally on its erector from the preparation building to the launch zone and then raised into the vertical position.

Europe’s next two Galileo satellites have received technical clearance for their launch this Friday. They are currently resting in place atop their Soyuz launcher. Yesterday saw the three-stage Soyuz ST-B launcher moved horizontally to the launch pad on the 600-meter long railway. It was then lifted into the vertical position to await the attachment of the Upper Composite — the... read more
