A picture from yesterday without payload. Interesting is the Glavkosmos sticker.
A future competitor for Arianespace.

Glavkosmos is part of the Starsem JV. Glavkosmos is the commercial launch arm of Roscosmos.

What do the different colors of the stars mean on the transporter erector?

Edit: Sometimes I'm blind, only the 10th and the 20th launch. So it has no meaning.
White means successful launch but cannot confirm if the same tradition applies.

red = celebration of every 10th launch (VS10 and VS20 are red)

Soyuz reaches the launch zone for Arianespace’s February 27 flight with OneWeb satellites

The launcher for Arianespace’s first Soyuz mission of 2019 is ready for payload integration following its transfer to the Spaceport’s ELS launch complex in French Guiana, which was completed earlier today.

With this rollout and the basic three-stage vehicle’s subsequent vertical positioning over its launch pad, Soyuz marked another key step toward Arianespace’s February 27 mission to orbit the initial six spacecraft in OneWeb’s constellation, which will provide affordable high-speed internet access for users around the world.

In procedures that have become familiar at the Spaceport, Soyuz was moved via a transport/erector rail car in a horizontal-transfer process from the MIK launcher assembly facility to the ELS launch zone. Once over the launch pad, the vehicle was erected into a vertical orientation, where it is suspended in place by four large support arms.

Ready for payload integration

Following this step’s completion, the mobile gantry was moved into position over the launcher – providing protection for the upcoming installation of Soyuz’ “upper composite,” which consists of the six OneWeb spacecraft and their dispenser system, plus the Fregat upper stage and payload fairing.

OneWeb is building the world’s largest and highest throughput satellite system to connect everyone, everywhere – by land, air, sea with a vision to bridge the digital divide once and for all.

Once placed in a near-polar orbit by Soyuz, the first six spacecraft – produced by the OneWeb Satellites joint venture of OneWeb and Airbus – will operate at an altitude of 1,200 km., giving customers extremely low latency and providing communications access to the entire world with fiber-quality internet connectivity.

Great opportunity to view the launch if you're in DC or London:

Everything still on track. Today is Launch Readiness Review. 🤞Tomorrow night launch parties at our DC and London Satellite Operations Centers. We are opening them up, so if you are nearby, come watch the action live as we make First Contact!

Do we have the launcher serial number?

Soyuz is cleared for Arianespace’s February 27 mission carrying OneWeb satellites

Arianespace’s Soyuz mission that will orbit global satellite operator OneWeb’s first six spacecraft has been authorized for launch tomorrow from the Spaceport in French Guiana.

Approval for liftoff was given at the conclusion of today’s launch readiness review, which verified the “go” status of Soyuz, its payload, the Spaceport’s infrastructure and the network of downrange tracking stations.

The February 27 mission – designated Flight VS21 in Arianespace’s numbering system – will be performed from the Spaceport’s purpose-built ELS launch facility for Soyuz.

Liftoff is scheduled at precisely 6:37 p.m. local time in French Guiana, with the six OneWeb satellites to be deployed during a flight sequence lasting 1 hour and 22 minutes.

Communications across the world

OneWeb is building the world’s largest and highest throughput satellite system to connect everyone, everywhere – by land, air, sea with a vision to bridge the digital divide once and for all.

Once placed in a near-polar orbit by Soyuz, the first six spacecraft – produced by the OneWeb Satellites joint venture of OneWeb and Airbus – will operate at an altitude of 1,200 km., giving customers extremely low latency and providing communications access to the entire world with fiber-quality internet connectivity.

OneWeb’s constellation will support a wide range of markets, including aeronautics, maritime, backhaul services, community Wi-Fi, emergency response services and more. The operator also is focused on connecting unconnected schools and working to bridge the digital divide for people everywhere.

The initial constellation will be compromised of approximately 650 satellites and will scale to more than 900 spacecraft as it grows to meet demand around the world. OneWeb signed a contract with Arianespace in 2015 for 21 Soyuz launches.
