As the Breeze M upper stage of our Proton M rocket continues its climb into space with the Y1B 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 11 minutes; after that the additional propellant tank will be jettisoned, and the 4th burn will start and complete. 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 4th burn ends.
