Connecting everyone, everywhere: Arianespace orbits the first six OneWeb satellites on its latest Soyuz success
Arianespace played a significant role in improving global connectivity with today’s Soyuz launch that deployed the initial six satellites in OneWeb’s constellation – which will provide affordable high-speed internet access for users around the world.
The cluster of spacecraft – produced by the OneWeb Satellites joint venture of OneWeb and Airbus – was successfully deployed into a circular low Earth orbit on Arianespace’s first Soyuz mission of 2019 (and the launch services company’s second mission overall this year).
Lifting off from the Spaceport precisely at the scheduled 6:37 p.m. launch time in French Guiana, the workhorse medium-lift vehicle delivered its payload during a flight lasting 1 hour and 22 minutes. Total payload lift performance was estimated at 1,945.2 kg.
After an initial powered phase of Soyuz’ three lower stages, the flight – designated VS21 in Arianespace’s numbering system – included two burns of the Fregat upper stage to place its passengers at their targeted deployment point. Dramatic, real-time views of key flight sequences – including liftoff, fairing jettisoning, as well as the two-phase separation of the OneWeb spacecraft passengers – were captured by four on-board cameras:
An ambitious partnership becomes a reality
Arianespace CEO Stéphane Israël congratulated OneWeb in his post-launch comments from the Spaceport and underscored the importance of today’s Soyuz success for both companies: “This initial mission makes our ambitious partnership – built around the launch of more than 600 OneWeb satellites – a reality.”
Arianespace’s first Soyuz mission in 2019 was performed from the Spaceport’s ELS launch complex.
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. The first six spacecraft will operate at an altitude of 1,200 km. in a constellation that will deliver extremely low latency for customers and provide communications access to the entire world with fiber-quality internet connectivity.
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 a total of 21 Soyuz flights from three launch bases (the Spaceport in French Guiana; Baikonur Cosmodrome in Kazakhstan and Vostochny in Russia), to be performed through 2020.
Following today’s launch success, Stéphane Israël announced that Arianespace and OneWeb have reached an agreement that completes the current launch services order. This agreement is for OneWeb’s use of Ariane 6’s inaugural flight in its A62 version, as well as options for two future Ariane 6 missions.
Connecting the world
The OneWeb 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.
Flight VS21 marked the 21st Soyuz launch performed from the Spaceport in French Guiana.
Speaking at the Spaceport, OneWeb CEO Adrian Steckel noted the group effort of many participants, including Arianespace, that led to today’s launch. “The notion of doing good is deep in the foundations of our company – and we are looking forward to doing our part in connecting the world, together with our partners,” he explained.
Nicolas Chamussy, Executive Vice President – Space Systems at Airbus Defence and Space, acknowledged Arianespace’s important role in this first step of establishing the OneWeb constellation. “I would like to thank Arianespace and Stéphane Israël: you and your teams have delivered spot-on, providing world-class access to space,” Chamussy said.
Maintaining the Spaceport’s 2019 launch cadence
Today’s success marked Soyuz’ 21st flight from the Spaceport since this vehicle’s 2011 introduction at French Guiana, as well as the second Arianespace mission from this equatorial launch site in 2019 – following the heavy-lift Ariane 5 flight that orbited Saudi Geostationary Satellite 1/Hellas Sat 4 and GSAT-31 on February 5.
With a busy launch schedule in 2019, Arianespace targets up to 12 missions from the Spaceport with Ariane 5, Soyuz and the light-lift Vega.
