In accordance with the decision of the State Commission on the morning of May 24, 2021, the Soyuz-2.1B carrier rocket with the ONEWEB acceleration unit and 36 ONEWEB spacecraft was exported from the technical on the starting complex of the Eastern cosmodrome and installed in the starting system. It is currently scheduled to be scheduled on Thursday, May 27, at 20:43 Moscow time.
Today at 01:00 Moscow time (07:00 local time) began transporting space for space for the starting complex. At the same time, the calculation of specialists of Roskosmos State Corporation has begun work on the preparation of starting equipment. After several hours, the rocket was installed in the starting system, and a mobile service tower was hitting.
Note that the mobile tower is designed to pre-train space-2 cosmic missiles. It provides access to personnel, applying devices, devices, etc. To all system of rocket carrier, located in a vertical position on the starting system of the cosmodrome. The tower protects the rocket and spacecraft from environmental impacts and has a system of rapid evacuation of personnel from all levels of the tower. Its infrastructure provides elevator and crane equipment, internal and external stairs, service platforms at different levels to provide circular access to the carrier rocket, as well as air ducts of the thermostatization system of the cosmic head, electrical equipment, control system, communications, alerts and television observation .
On Monday, as part of the first starting day, the assembly of measurement system schemes, control systems and measurement systems of refueling levels, docking of filling and pneumocommunications are scheduled. Then after lunch – autonomous checks of the dispersal block “Frigate” of the development and production of the SA Science and Production Association Lavochkina and Navy-2.1b launch vehicles produced by the Progress Rocket and Space Center (both enterprises are included in the Roskosmos State Corporation), as well as conducting checks and preparation of ONEWB spacecraft to launch.
To date, the OneWeb satellites group at a low near-earth orbit has 182 spacecraft. The next on May 27, the launch must bring the number of ONEWB spacecraft in orbit up to 218. OneWeb low-bit spacecraft are designed to provide terrestrial consumers with high-speed Internet.
