We had a successful liftoff about 11 minutes ago of the ILS Proton M Breeze M rocket, which is carrying the Yamal 402 satellite onboard. The three stages of the Proton vehicle have performed as planned, and it is up to the Breeze M upper stage to complete the mission. The upper stage has begun its first burn, which is scheduled to last about 5 minutes.
We have confirmed that the Breeze M upper stage has successfully completed its 3rd burn, as well as jettisoning its additional propellant tank. The vehicle is now in a 5-hour coast period, during which we will have nothing to report. The 4th burn is scheduled to start around 5:07 pm EST or 22:07 GMT. Separation of Yamal 402 spacecraft is scheduled to follow the 4th burn completion by about 12 minutes.
As the Breeze M upper stage of our Proton M rocket continues its climb into space with the Yamal 402 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 17 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.
