On the cosmodrome of Russia there is an active preparation for the upcoming launches. So, in accordance with the decision of the State Commission in the morning of June 28, 2021, the “Soyuz-2.1b” carrier rocket with the ONEWEB satellite spacecraft was removed from the technical on the Eastern satellite company, and installed in the starting system. Start scheduled for July 1 at 15:48 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 joint calculation of specialists of Roskosmos State Corporation has begun work on the preparation of the infrastructure of starting equipment. Later, the rocket was installed in the starting system and drove a mobile service tower.
This construction allows you to work on preparing for the launch of the carrier missile in the most difficult climatic conditions. The height of the service tower is 52 m, the weight is 1600 tons and consists of seven tiers. The use of this tower allows you to significantly increase the security of personnel in the preparation of a carrier missile to the upcoming start.
As part of the first starting day, the assembly of the measurement system schemes, control systems and measurement systems of refueling levels, docking of filling and pneumocommunications are scheduled. Then – autonomous checks of the accelerated block “Frigate” of the production of the SA Science and Production Association Lavochkina and an hour later – the “Soyuz-2.1b” carrier launch vehicles produced by the Progress Rocket and Space Center (both enterprises enter the perimeter of Roskosmos state corporation).
The oneweb satellites group at a low near-earth orbit today has 218 spacecraft. The upcoming launch must bring the number of ONEB spacecraft in orbit up to 254. OneWeb low-bit satellites are designed to provide ground consumers with high-speed Internet.
