Soyuz October 11, 2021

With Flight ST36, Arianespace will have orbited more than half of OneWeb’s constellation

- The next Arianespace mission is planned from Vostochny Cosmodrome with Soyuz on October 14 to deliver 36 satellites into orbit, bringing the total OneWeb’s fleet to 358 satellites in Low Earth Orbit.

– ST36 represents an important step in OneWeb and Arianespace’s partnership as it will allow the operator to have more than half of its constellation on orbit.

– This 61st Soyuz mission, the 11th for OneWeb, will be the tenth launch of Arianespace in 2021.

Flight ST36, performed by Arianespace and its Starsem affiliate from the Vostochny Cosmodrome on October 14, at 6:40 p.m. local time (09:40 a.m. UTC), will put 36 of OneWeb’s satellites into a near-polar orbit at an altitude of 450 kilometers. The mission will have a total duration of 3 hours and 51 minutes and will include nine separations of four satellites each, which will raise themselves to their operational orbit.

This 61st launch of Soyuz operated by Arianespace, the 11th for OneWeb, will raise to 358 the number of satellites deployed for the global telecommunications operator. The constellation, once complete, will include 648 satellites. Thus, ST36 will be the launch taking OneWeb more than halfway to the finish line, with 358 of its satellites being on orbit.

OneWeb’s constellation will deliver high-speed, low-latency connectivity services to a wide range of customer sectors including aviation, maritime, backhaul services, as well as governments, emergency response services and more. Central to its purpose, OneWeb seeks to bring connectivity to every place 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.

OneWeb Satellites, a joint venture between OneWeb and Airbus Defence and Space, 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.

About Arianespace 

Arianespace uses space to make life better on Earth by providing launch services for all types of satellites into all orbits. It has orbited more than 1,000 satellites since 1980, using its family of three launchers, Ariane, Soyuz and Vega, from launch sites in French Guiana (South America) and from the Russian cosmodromes in Baikonur and Vostochny. Arianespace is headquartered in Evry, near Paris, and has a technical facility at the Guiana Space Center in French Guiana, plus local offices in Washington, D.C., Tokyo and Singapore. Arianespace is a subsidiary of ArianeGroup, which holds 74% of its share capital, with the balance held by 15 other shareholders from the European launcher industry. www.arianespace.com
