…for fueling, marking a new step in the preparation campaign for its nighttime launch on November 30. Built by EADS‘ Astrium division for the French CNES space agency, Pléiades 1B has completed initial checkout in the Spaceport’s S1B clean room facility, and has now been moved to the larger, multi-bay S5 payload processing center for the loading of its onboard propellant.
This satellite is designed to provide optical observation coverage with 50-centimeter resolution for the French and Spanish defense ministries, along with civil institutions and private users. After the launch by Soyuz, Pléiades 1B will join the twin Pléiades 1A satellite, which was lofted by an Arianespace Soyuz mission in December 2011 for operation from a quasi-polar heliosynchronous orbit. Offering exceptional agility to maximize acquisitions over specific areas of interest, the Pléiades satellites can be “rush programmed” to overfly designated target zones, with an automated production system generating 20 x 20km orthorectified images in 30 minutes.
Pléiades 1B’s transfer for fueling at the Spaceport is detailed in this photo series. In the two images at left, the Astrium-built imaging satellite is positioned on a pallet inside the S1B clean room facility. The air cushion pallet then passes through an airlock for placement in the large CCU3 spacecraft transportation container (third photo) for its move across the Spaceport to the S5 payload preparation center.

The system’s capabilities were demonstrated by Pléiades 1A’s imaging of areas along the U.S. eastern seaboard affected by Hurricane Sandy, underscoring the delivery of high-detail data that is essential for emergency response. Arianespace’s upcoming Soyuz flight with Pléiades 1B is designated VS04 in the company’s mission numbering system for launcher family operations from the Spaceport. It will continue the medium-lift vehicle’s mission pace, and follows the VS03 launch on October 12 with a pair of European Galileo navigation satellites; the VS02 flight on December 17, 2011, which carried Pléiades 1A, along with the Chilean SSOT civilian/defense imaging satellite and four French ELISA micro-satellites for defense electronic intelligence gathering: and the historic VS01 maiden liftoff of Soyuz from French Guiana on October 21, 2011 with two Galileo spacecraft.
