Arianespace mission personnel provides details on Soyuz’ nearly 4-hour flight sequence

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…
