Mission Success!

We have had a successful mission with the Proton M Breeze M rocket, carrying the Yamal-401  satellite built by Airbus. We have confirmation that the satellite separated from the vehicle on schedule at 4:17 am EST, or 09:17 GMT, approximately 9 hours and 1 minute after liftoff.
Everything occurred as planned with ignition, shutdown and separation of the Proton’s first three stages. Then the Breeze M upper stage with the satellite continued the mission, igniting four times, and then releasing the satellite into transfer orbit.

Yamal-401 | Second Burn

As the Breeze M upper stage of our Proton M rocket continues its climb into space with the Yamal-401 satellite onboard, we have received confirmation that the 2nd burn of the upper stage occurred and shut down as scheduled.
The next events are scheduled for about 2 hours from now. The Breeze M upper stage will ignite for a 3rd time and burn for approximately 18 minutes; after that the additional propellant tank will be jettisoned. All this will happen in a span of almost 20 minutes while the vehicle is again out of range of a ground station. We should reacquire the vehicle shortly after the APT is jettisoned.
