We have confirmed that the Breeze M upper stage has successfully completed its 3rd and 4th burn, as well as jettisoning its additional propellant tank. The vehicle is now in a 5 and a half hour coast period, during which we will have nothing to report. The 5th burn is scheduled to start around 10:27 p.m. EST, or 03:27 GMT. Separation of the Inmarsat-5 F1 spacecraft is scheduled to follow the 5th burn completion by about 13 minutes.

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.

We had a successful liftoff about 10 minutes ago of our Proton M Breeze M rocket, which is carrying the Inmarsat-5 F1 satellite. 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 around 4 minutes.

Over the past few days there has been much activity in preparation for the launch of Inmarsat-5 F1.  The Proton launch vehicle is in Hall 111 while the Breeze-M is in Hall 101, both are undergoing testing.  The payload fairing is in Hall 101 and is ready for joint operations to begin.   And the SC is completing its own series of tests prior to joining the Breeze-M in Hall 101. A lot of activity!

Today, right on schedule, the Breeze-M upper stage arrived in Baikonur at Yubileiny Airfield on an Antonov 124.   It was then offloaded to a rail car and a few hours later rolled into Hall 101 for testing in preparation for joint operations.    Testing on the SC is proceeding very well and will soon move into Hall Hall 101 for mating with the Breeze-M.   This campaign is well underway!
