As the Breeze M upper stage of our Proton M rocket continues its climb into space with the Inmarsat-5 F1 satellite, 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 1 hour from now. The Breeze M upper stage will ignite for a 3rd time and burn for approximately 10 minutes; after that the additional propellant tank will be jettisoned and the Breeze M will complete its 4th burn. All this will happen while the vehicle is again out of range of a ground station. We should reacquire the vehicle around 5 pm EST.
