mission
description

Flight ST35, the 30th commercial mission from the Baikonur Cosmodrome in Kazakhstan performed by Arianespace and its Starsem affiliate, will put 34 of OneWeb’s satellites bringing the total fleet to 322 satellites into a near-polar orbit at an altitude of 450 kilometers. After separation, the satellites will raise themselves to their operational orbit. 

With Flight ST35, Arianespace will put in orbit a total of 455 spacecraft from Airbus Defence and Space (including from 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 18 additional payloads.

Payload

OneWeb satellites #289 to #322

 

Flight ST35, the 30th commercial mission from the Baikonur Cosmodrome in Kazakhstan performed by Arianespace and its Starsem affiliate, will put 34 of OneWeb’s satellites bringing the total fleet to 322 satellites into a near-polar orbit at an altitude of 450 kilometers. After separation, the satellites will raise themselves to their operational orbit. 

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.

  • With Flight ST35, Arianespace will put in orbit a total of 455 spacecraft from Airbus Defence and Space (including from 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 18 additional payloads.
  • The first eight OneWeb missions carrying 288 satellites were successfully orbited by Arianespace.

 

DID YOU KNOW?

ST35 launch represents an important step in Arianespace’s career, as it will see the 1,000th satellite processed by the European launch service operator reach its orbit. Throughout a 41-year history, Arianespace has orbited all types of satellites and spacecraft, from connectivity and broadcast to Earth observation and science, allowing its customers to reach all kind of destinations into space, from close orbits to deep space locations.
