Launch kit

We can't read, whether it is a Soyuz ST-B or a Soyuz ST-A.
We know it's an ST-B. But there may be launches in the future, about which we do not know.
At least you can see from the tiny Fregat image in the launch kit it's not an MT. (compare VS26 Launch Kit)

 The Soyuz-ST-B rocket, which is designed to launch the next batch of 34 OneWeb spacecraft into orbit, was taken to the launch pad at the Guiana Space Center (French Guiana). On Monday, February 7, 2022, the first launch day schedule began.

The first launch day will include operations to dock the pneumatic and refueling communications "package" (first and second stages) of the rocket and to assemble the control, measurement and temperature control circuits of the launcher. In addition, on Monday will begin docking work on the rocket with the space head part of the upper stage "Fregat-M" and spacecraft. The peculiarity of the preparation of the launch at the Guiana Space Center is a separate transportation of the rocket (the assembly of three stages) and space head part, followed by their assembly on the launcher with a mobile service tower.

The preparation of the launch vehicle and the operation of the ground equipment supplied by the Russian side is provided by specialists from subsidiaries of Roskosmos State Corporation. The launch will be carried out by joint Russian-European launch teams. The operator is the European launch services provider Arianespace, while Glavkosmos company (a part of Roskosmos State Corporation) is the main contract integrator of the project from the Russian side, ensuring cooperation between Russian space industry enterprises and Arianespace at all stages.

The launch of a Soyuz-ST-B launch vehicle is scheduled for Feb. 10, 2022 at 21:09:37 Moscow time. There are currently 394 OneWeb communications satellites in Earth orbit and the upcoming launch will bring their number to 428. The next OneWeb missions through 2022, which will use Russia's Soyuz-2.1b launch vehicle, will allow the company to begin providing services around the world as early as this year.

For OneWeb, this will be its thirteenth launch using Russian Soyuz-2 launch vehicles and the second from the Guiana Space Center, with five launches from the Baikonur Cosmodrome and six more from Russia's newest launch site, Vostochny.

Russian Soyuz rocket installed on Kourou spaceport’s launch pad to orbit OneWeb satellites.

The launch of the carrier rocket is scheduled for February 10.

7 FEB, 05:56

MOSCOW, February 7. /TASS/. A Soyuz-ST-B carrier rocket was delivered to the launch pad of the Kourou spaceport in French Guiana to orbit the next batch of British OneWeb communications satellites, Russia’s State Space Corporation Roscosmos announced on Friday.

"A Soyuz-ST-B rocket, which is to launch the next batch of 34 OneWeb spacecraft into orbit, was taken to the launch pad at the Guiana Space Center (French Guiana). On Monday, February 7, 2022, the first launch day schedule works began," Roscosmos said on its website.

The pre-launch preparations at the Guiana Space Center include separate transportation of the rocket (an assembly of three stages) and the spacehead unit and their subsequent assembly on a launcher, using a mobile service tower, it said.

"The launch of a Soyuz-ST-B carrier rocket is scheduled for February 10, 2022, at 21:09:37 Moscow time," Roscosmos specified.

CEO of the commercial launch operator Glavkosmos (part of Roscosmos) Dmitry Loskutov earlier told TASS that seven launches of British OneWeb communications satellites were scheduled for 2022. The first launch was scheduled to take place from the Guiana space center (the Kourou cosmodrome) in February, he specified.

British OneWeb low-orbit satellites are designed to create a space-based communications system to provide high-speed Internet access in any locality worldwide. Currently, the OneWeb orbital cluster comprises 394 satellites. All of them were orbited by Russian Soyuz carrier rockets.

Soyuz to launch the 13th OneWeb cluster

Page author: Anatoly Zak; Last update: February 10, 2022

Page editor: Alain Chabot; Last edit: February 9, 2022

A Soyuz rocket is poised to continue the deployment of the OneWeb constellation with the first mission in 2022 scheduled to lift off on February 10 at 21:09 Moscow Time (1:09 p.m. EST). Launching from the near-equatorial launch site in French Guiana, it will be the 13th OneWeb mission, boosting the overall number of spacecraft in the network from 394 to 428.

The 13th Soyuz mission with OneWeb satellites at a glance:

Mission and spacecraft designation   
VS27, ST38 OneWeb (34 satellites: 395-428)

Launch vehicle   
Soyuz ST-B No. Ya15000-018 / Fregat No. 133-19

Payload fairing   
81KS

Launch site   
Kourou, ELS

Launch date and time   
2022 Feb. 10, 15:09:37 French Guiana time

Payload mass (including dispenser)   
36 OneWeb satellites, 5,495 kilograms total

Target orbit   
Altitude: ~475 kilometers, inclination 87.4 degrees*

Preparations for launch

The 13th OneWeb mission had the designation VS27 according to Paris-based Arianespace venture, which manages Soyuz launches from the Guiana space center in South America.

The launch was previously planned for January 6, but it was delayed until February 10, 2022.

A transport plane with OneWeb satellites for the mission landed at the airport in Cayenne, French Guiana, on Jan. 14, 2022.

The active launch campaign for the mission started in French Guiana with the fueling of the Fregat upper stage on January 15 by a team of specialists from TsENKI ground infrastructure division at Roskosmos. On January 20, another group of engineers from RKTs Progress, which builds the Soyuz rocket family, was due at the center to start processing of the Soyuz ST-B vehicle.

The fueled Fregat was transferred from the FCube building to the S3B-NH assembly facility on February 1 and, the next day, the space tug was integrated with 34 satellites previously attached to a common payload dispenser. The assembly of the rocket's upper composite, including the Fregat, satellites and the payload fairing, was completed on February 4.

The rollout of the three-stage booster cluster to the launch pad took place on February 7, followed by the delivery and integration of the payload section with the rocket on the same day inside the movable service tower positioned on the pad. The integrated tests and dress rehearsals were conducted on February 8 and 9, clearing the vehicle for launch the next day.

Launch profile of the 13 OneWeb mission

A Soyuz-2 (ST-B) rocket carrying a cluster of 34 OneWeb satellites is scheduled to lift off from the ELS complex in Kourou, French Guiana, on Feb. 10, 2022, at 15:09: 37 local time in French Guiana (1:09 p.m. EST, 21:09 Moscow Time).

After eight seconds of vertical ascent from the sea-side pad, the launch vehicle will begin tilting northward, heading over the Atlantic Ocean to align its ascent trajectory with a near-polar orbit inclined 87.77 degrees toward the plane of the Equator.

The four boosters of the first stage will separate 1 minute 58 seconds into the flight, followed by the payload fairing splitting into two halves and dropping off 3 minutes and 37 seconds after the liftoff. The second (core) stage will separate 4 minutes and 48 seconds in flight, moments after the third stage ignites its RD-0124 engine. The latter will operate until 9 minutes and 24 seconds in flight, completing its burn just short of orbital velocity, which will ensure the booster's immediate reentry over the Atlantic and a splashdown between Canada and Greenland.

In the meantime, the Fregat upper stage will fire its engine for around four minutes, starting 10 minutes and 24 seconds after launch. The maneuver will form the initial transfer orbit, which the stack will climb passively for around 43 minutes.

During the ascent of the Soyuz rocket and the most critical maneuvers of the Fregat upper stage, the mission will be crossing the communications range of various ground stations from Guiana to Bermuda Islands to the Arctic Ocean, downlinking data about its status.

Upon reaching the apogee (highest point) of the transfer trajectory, 54 minutes and 15 seconds after launch, Fregat will re-ignite its engine for around two minutes to make its orbit circular at an altitude of around 1,000 kilometers.

The first pair of OneWeb satellites will be released in opposite directions from their dispenser exactly one hour after launch.

In the following 15 minutes after the release of the first pair of satellites, Fregat should make a 15-second burn with its small attitude control thrusters to get in position for another release around three minutes later, this time of four satellites at the 1-hour 19-minute mark in the flight.

The Fregat is then programmed to repeat its thruster firing and release routine seven more times, evenly distributing the quartets of satellites along their orbit, according to the following timeline:

Separation 3 – L+1 hour 38 minutes;
Separation 4 – L+1 hour 57 minutes;
Separation 5 – L+2 hours 17 minutes;
Separation 6 – L+2 hours 36 minutes;
Separation 7 – L+2 hours 55 minutes;
Separation 8 – L+3 hours 14 minutes;
Separation 9 – L+3 hours 33 minutes.

The empty Fregat is then programmed to initiate a braking maneuver with its main engine which is designed to push the stage on a disposal orbit, resulting in its quick destruction in the upper atmosphere 5 hours and 39 minutes after launch.
