description

Flight ST32 

This 57th Soyuz mission conducted by Arianespace and its Starsem affiliate will be operated from Vostochny Cosmodrome for the fourth time and represents OneWeb’s seventh launch overall.

Realizing revolution in space with ST32 mission: OneWeb will take a new step by increasing its satellite fleet to more than 200 spacecraft.

By operating this flight on behalf of OneWeb, Arianespace participates in the fulfilment of its customer’s ultimate ambition: providing internet access for everyone, everywhere, all the time.

Payload

OneWeb

Flight ST32, the fourth commercial mission from Vostochny Cosmodrome performed by Arianespace and its Starsem affiliate, will put 36 of OneWeb’s satellites bringing the total fleet to 218 satellites into a near-polar orbit at an altitude of 450 kilometers. After separation, the satellites will raise themselves to their operational orbit.

The first six OneWeb satellites were successfully orbited by Arianespace on Soyuz Flight VS21 from French Guiana on February 27, 2019. On February 7, 2020, Arianespace and its Starsem affiliate launched 34 OneWeb satellites from Baikonur Cosmodrome on Soyuz Flight ST27. On March 21, 2020, the team successfully delivered an additional 34 satellites into orbit on Soyuz Flight ST28. On December 18, 2020, the first Soyuz from Vostochny placed in orbit 36 satellites on Flight ST29. On March 25, 2021, the second Soyuz from Vostochny successfully placed in orbit 36 satellites on Flight ST30. Finally, ST31 mission on April 26, 2021, orbited 36 satellites from Vostochny.

OneWeb’s mission is to bring internet everywhere to everyone, by creating a global connectivity platform through a next generation satellite constellation in low Earth orbit. OneWeb’s constellation of 650 satellites will deliver high-speed, low-latency enterprise grade connectivity services to a wide range of customer sectors including enterprise, government, maritime and aviation customers. Central to its purpose, OneWeb seeks to bring connectivity to every unconnected area where fiber cannot reach, and thereby bridge the digital divide.

Once deployed, the OneWeb constellation will enable user terminals that are capable of offering 3G, LTE, 5G and Wi-Fi coverage, providing high-speed access globally – by air, sea and land.

In 2021, the company is focused on scaling the satellite constellation to launch commercial services starting at the end of 2021 to the UK, Alaska, Canada, Northern Europe, Greenland, Iceland, and the Arctic Seas.

OneWeb Satellites is a joint venture between OneWeb and Airbus Defence and Space, where OneWeb Satellites is the constellation’s prime contractor. The satellites were built thanks to its leading-edge satellite manufacturing process that can build up to two satellites a day on a series production line dedicated to the assembly, integration, and testing of the satellites. The facility is running at full speed, within the coronavirus pandemic guidelines, manufacturing satellites that are tested and ready now, and also for future launches.

With the launch of 36 OneWeb satellites on Flight ST32, Arianespace will put in orbit a total of

349 spacecraft from Airbus Defence and Space (including OneWeb Satellites – a joint-venture between OneWeb and Airbus Defence and Space founded in 2016).

The Arianespace backlog of payloads remaining to be launched for Airbus Defence and Space (excluding the remaining OneWeb satellites) counts 20 additional payloads.

After ST32, 12 Soyuz launches remain under contract with Arianespace which has more than 440 additional satellites to be launched in the Arianespace’s backlog.

RUAG Space AB (Linköping, Sweden) is the prime contractor in charge of development and production of the dispenser system used on Flight ST32. It will carry the satellites during their flight to low Earth orbit and then release them into space.

The dedicated dispenser is designed to accommodate up to 36 spacecraft per launch, allowing Arianespace to timely deliver the lion’s share of the initial OneWeb constellation.
