Our team is so excited for the upcoming launch!

Preparations are well underway here at OneWeb HQ, and we’re almost ready for this evening’s events.

Here’s a sneak peak at what’s going on behind the scenes…

Separation of 2 and 3 steps occurs according to the "hot" scheme. The 3 stage engine starts before separation and the gas jet diverts the 2 stage. The 2 and 3 stages sep takes place according to the 'hot' scheme. The 3 st engine ignites before separation, and the gas jet removes the 2 st..

Roskosmos adds 34 more satellites to OneWeb constellation

02/11/202200:45

On Thursday, February 10, 2022, at 21:09:37 Moscow time, the Soyuz-ST-B launch vehicle was launched from the launch complex of the Guiana Space Center. After 3.5 hours, the Fregat-M upper stage successfully launched another batch of 34 OneWeb satellites into low Earth orbit.

The successive separation of nine groups of spacecraft from the Russian upper stage proceeded normally. All OneWeb satellites have been successfully launched into their assigned orbits and taken under control. After the completion of the breeding and separation of the spacecraft, the Fregat upper stage, for which this is already the 106th flight, will be deorbited, and approximately at the sixth hour of the flight, its fireproof elements will be flooded into the uninhabited part of the Indian Ocean.

The spacecraft were launched under a contract between Glavkosmos (part of the Roscosmos State Corporation) and the European launch services provider Arianespace in close cooperation with other subsidiaries of Roscosmos (Progress Rocket and Space Center, Scientific and Production Association named after S. A. Lavochkina, Center for the Operation of Ground-Based Space Infrastructure Objects).

For OneWeb, this was the thirteenth launch using Russian Soyuz-2 launch vehicles and the second from the Guiana Space Center. Five launches were carried out from the Baikonur Cosmodrome, and six more from the newest Russian Vostochny Cosmodrome.

Currently, there are already 428 OneWeb communication satellites in low-Earth orbit. The next OneWeb missions throughout 2022, which will also use the Russian Soyuz-2 launch vehicle, will allow OneWeb to start providing services around the world this year.

OneWeb spacecraft are designed to create a space communication system that provides high-speed Internet access anywhere in the world. Internet access via the OneWeb satellite system will be provided through 40 ground terminal stations that will be deployed on the Earth's surface. OneWeb terminals will be self-contained, able to supply themselves with energy and well protected from the influence of adverse environmental factors.

Each of the terminals will be able to provide high-speed Internet access in its coverage area via Wi-Fi, LTE or 5G technologies. A licensed radio frequency band or, where available, an open public Wi-Fi, LTE or 5G radio frequency band will be used.

Baikonur begins to prepare for the launch of OneWeb spacecraft

02/15/202211:12

A new batch of 36 OneWeb spacecraft was delivered to the Baikonur cosmodrome as part of mission No. 38. They arrived at the Krainy airport by An-124 aircraft. Their launch using the Soyuz-2.1b launch vehicle and the Fregat upper stage is scheduled for March 5, 2022 at 01:41 Moscow time.

Specialists of the Yuzhny Space Center (a branch of the Center for the Operation of Ground-Based Space Infrastructure Objects, part of the Roscosmos State Corporation) unloaded the spacecraft and transported them to site No. 112 of the Baikonur Cosmodrome. The next stage of technological measures is the preparation of devices at the technical complex.

OneWeb low-orbit spacecraft are designed to provide terrestrial consumers with high-speed Internet. There are currently 428 OneWeb communications satellites in orbit. The next OneWeb missions throughout 2022, which will also use the Russian Soyuz-2 launch vehicle, will allow OneWeb to start providing services around the world this year.

Vostok launch complex at Baikonur is being prepared for the launch of OneWeb spacecraft

02/18/202217:19

At the Baikonur Cosmodrome, intensive preparations have begun for the Vostok launch complex at site No. 31 for the launch of the next batch of spacecraft of the OneWeb satellite company as part of mission No. 38.

After the successful launch of the Soyuz-2.1a carrier rocket with the Progress MS-19 cargo spacecraft, which took place on February 15, 2022, the specialists of the Yuzhny Space Center (a branch of the Center for the Operation of Ground-Based Space Infrastructure Facilities, part of the Roscosmos State Corporation) started post-launch repair and restoration work.

At the same time, on February 16, preparations began for the launch complex to receive the next space rocket. Currently, work is underway to assemble control and measurement system circuits, fill receivers with compressed gases and receive propellant components. The preparation will continue until the rocket is taken out of the assembly and test building to the launch complex.

The launch of the Soyuz-2.1b carrier rocket with the Fregat upper stage and 36 OneWeb spacecraft from the Baikonur Cosmodrome is scheduled for March 5, 2022 at 01:41:02 Moscow time.

02/19/202212:15

At the Baikonur Cosmodrome, the refueling of the Fregat upper stage was successfully completed, designed to launch a new batch of 36 OneWeb spacecraft into low Earth orbit as part of mission No. 38.

After the completion of the technological operations that were carried out at the refueling and neutralization station for a week, the specialists of the Yuzhny Space Center (a branch of the Center for the Operation of Ground-Based Space Infrastructure Facilities, part of the Roscosmos State Corporation) transport the upper stage to the finishing chamber of the assembly and test building of the site No. 112 of the cosmodrome.

The launch of the Soyuz-2.1b carrier rocket with the Fregat upper stage and OneWeb spacecraft is scheduled for March 5, 2022 from the Vostok launch complex (site No. 31) of the Baikonur Cosmodrome.

At Baikonur, a "package" of the Soyuz-2.1b rocket was assembled to launch OneWeb spacecraft

22.02.202207:34

Work continues at the Baikonur Cosmodrome to prepare the Soyuz-2.1b launch vehicle for the launch of 36 new OneWeb spacecraft as part of mission No. 38. The assembly of the “package” (first and second stages) was completed in the assembly and test building at site No. 31 Soyuz-2.1b rockets.

The next step will be to conduct autonomous tests of missile control and measurement systems. All work performed by specialists of the Yuzhny Space Center (a branch of the Center for the Operation of Ground-Based Space Infrastructure Objects, part of the Roscosmos State Corporation) at the technical and launch complexes is being carried out according to schedule.

The launch of the Soyuz-2.1b carrier rocket with the Fregat upper stage and 36 OneWeb spacecraft is scheduled for March 5, 2022 at 01:41:02 Moscow time from the 31st site of the Baikonur Cosmodrome. The satellites will be launched into an orbit at a height of 450 km, after which they will be independently launched into an orbit at a height of 1200 km. To date, Russian rockets of the Soyuz-2 family have launched 428 OneWeb satellites into orbit.

In light of Putin's behavior it is appalling that these launches are allowed to continue, and they're even intermediated by ArianeSpace!

This collaboration is shameful.

I think that those Soyuz rockets for OneWeb are mostly if not completely already paid for, so canceling those launches would not harm the Russian space industry.

The problem for a company like oneWeb is it has not much room to manoeuvre. A year delay would cost it dearly, possible mean it would lose contracts and maybe become unviable.

It's currently in probably quite vicious competition with Starlink behind the scenes, so unless we basically want starlink to have a monopoly, we'll need to suck it up a little.
