on Saturday, September 11, 2021, the removal of the “Soyuz-2.1b” launch vehicle was taken out with an overclocking unit “Frigate” and 34 ONEWEB spacecraft from the installation and test case of the site No. 31. Currently, the space appointment missile The starting complex “East” of the Baikonur cosmodrome and is preparing for launch, which is scheduled for September 14th.
Currently, specialists of Roskosmos state corporation perform technological operations under the first-day program. In particular, the schemes and autonomous tests of systems and aggregates of spacecraft, acceleration block and carrier missile, and the interaction of on-board equipment and ground equipment is checked.
Present works are held as part of the execution of the contracts of the company “Glavkosmos” (a subsidiary of the Roskosmos State Corporation) with the European Supplier of the Arianespace launch services (Operator of the ONEWEB spacecraft) and Starsem. These work conducts a joint calculation of representatives of foreign customers and subsidiaries of Roskosmos: RCC “Progress”, NGO Lavochkina, Cennie and Glavkosmos.
Now the grouping of ONEWEB satellites at a low near-earth orbit has 288 spacecraft. The upcoming start must bring the number of OneWeb devices at an near-earth orbit up to 322. OneWeb low-bit spacecraft are designed to provide land consumers with high-speed Internet.

The Soyuz-2 carrier rocket is developed on the basis of the Soyuz-y serial missile. The head developer is the Progress Rocket and Space Center (Samara, enters Roscosmos). On the Rockets of the Soyuz-2 family, advanced motor installations and modern control systems and measurements are applied, which increases technical and operational characteristics. Constructively “Soyuz-2”, as well as all the missiles of the Soyuz family, made under the scheme of longitudinal transverse division of rocket steps. In combination with the Frigate acceleration unit, it is designed to launch spacecraft for near-earth orbits of various heights and inclinations, including geo-and-geostationary orbits, as well as flying paths.
