Six OneWeb satellites are integrated for their upcoming Arianespace Soyuz launch


Arianespace has completed a major preparation milestone for its next Soyuz launch with integration of the mission’s high-profile payload: the initial six spacecraft in OneWeb’s constellation, which will provide affordable high-speed internet access for users around the world.

The spacecraft – produced by the OneWeb Satellites joint venture of OneWeb and Airbus – will be orbited on Arianespace’s first Soyuz mission of 2019 from the Spaceport in French Guiana. Designated Flight VS21, it has a targeted liftoff of February 26.

Integration of the six satellites on their multi-payload dispenser system – which will deploy them during the mission from atop Soyuz’ Fregat upper stage – was completed in the Spaceport’s S3B payload preparation facility.

Helping OneWeb connect the unconnected

Once placed in a near-polar orbit by Soyuz, the OneWeb spacecraft 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 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.

To develop its constellation of 150-kg. satellites, OneWeb signed a contract with Arianespace in 2015 for 21 Soyuz launches.

The upcoming Flight VS21 will mark the 21st liftoff of Soyuz from French Guiana since this medium-lift launcher’s 2011 operational debut at the Spaceport.

As Arianespace’s second of up to 12 missions planned for 2019, Flight VS21 also will continue the momentum gained from the company’s year-opening launch: Flight VA247 with Ariane 5, which successfully delivered a pair of telecommunications relay platforms – Saudi Geostationary Satellite 1/Hellas Sat 4 (HS-4/SGS-1) and GSAT-31 – to geostationary orbit on February 5.

Looks like RIA confused the timezones. CSG says February 26 at 21:37 UTC (6:37 pm local time):

Arianespace to orbit the first six satellites of the OneWeb constellation

For its second mission of the year — and the initial flight in 2019 with the Soyuz medium launcher — Arianespace will perform the first launch for the OneWeb constellation.

By operating this maiden flight, out of 21 launches on behalf of the global satellite operator, Arianespace participates in the fulfilment of its customer’s ultimate ambition: providing Internet access for everyone, everywhere.

This mission will bring the number of constellation satellites orbited by Arianespace to 109, which shows a remarkable ability to deploy any type of constellation with its current and future family of launchers.

The Launch Readiness Review (LRR) will take place on Monday, February 25, 2019 in Kourou to authorize the start of operations for the final countdown.

Flight VS21, the 21st Soyuz mission from the Guiana Space Center, will put six OneWeb F6 satellites for U.S operator OneWeb into a circular low Earth orbit at 1,000 km. (close to their operational orbit), along with four Mass Flight Simulators (MFS) that will not be separated from the launcher’s dispenser system.

OneWeb’s mission is to deliver global communications through a next-generation satellite constellation that will bring seamless connectivity to everyone, everywhere. With its system deployed, the OneWeb constellation will enable user terminals capable of offering 3G, LTE, 5G and Wi-Fi coverage, giving high-speed access around the world – by air, sea and land.

Composed of approximately 650 satellites, OneWeb initial constellation will be orbited by Arianespace using 21 Soyuz launchers operated through 2020 from Kourou in French Guiana, Baikonur in Kazakhstan, and Vostochy in Russia.

OneWeb Satellites – a joint-venture between OneWeb and Airbus Defence and Space – is the prime contractor of the constellation. RUAG Space AB, on the other hand, is in charge of the development and production of the innovative

dispenser system that will carry the six satellites and the four Mass Flight Simulators aboard Flight VS21. As for APCO Technologies, it is responsible for designing and building the four Mass Flight Simulators.

To watch a live, high-speed online transmission of the launch (including commentary in French and English from the launch site), go to arianespace.com or to youtube.com/arianespace on February 26, 2019, beginning 20 minutes before liftoff.

Most likely, the launch will be postponed to a later date.

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.
