These integration steps are performed with the Soyuz aligned in horizontal jigs positioned with the MIK facility’s floor-level rail system, and will be followed by mating of the launcher’s centerline third stage. Once completed, the Soyuz will be ready for its rollout to the Spaceport’s ELS launch pad, where it will be raised to the vertical position —preparing it for integration of the O3b Networks satellite payload, performed with the protection of a 53-meter-tall mobile gantry.

The upper and lower segments of Soyuz’ core second stage are mated in the Spaceport’s MIK launcher integration building (photo at left). The distinctive “hammerhead” shape enables Soyuz’ four second-stage boosters to be clustered around the core stage, as shown during the installation process in the photo at right.

The O3b Networks satellites to be orbited on Arianespace’s June 24th mission were built by Thales Alenia Space, and are to be positioned at a medium-Earth orbit altitude of 8,063 km. Operating in Ka-band, these spacecraft will become part of O3b Networks’ system that offers high-speed, low-cost, low-latency Internet and telecommunications services for customers in emerging markets.
This Soyuz flight will be Arianespace’s fifth with the medium-lift vehicle from the Spaceport since its introduction at French Guiana in October 2011. Soyuz is part of the company’s complete launcher family, which also includes the heavyweight Ariane 5 and light-lift Vega. In addition to the first batch of O3b spacecraft to be lofted during the June mission, another Arianespace flight is scheduled to orbit four more later this year for O3b Networks, followed by an additional four in 2014.
