+ Mission Successful!
We have had a successful mission with the Proton M Breeze M
rocket, carrying the Inmarsat-4 F3 satellite built by EADS
Astrium for Inmarsat. We have had confirmation that the
satellite separated from the vehicle on schedule at 3:46 am
Eastern time, or 7:46 GMT, 9 hours and 3 minutes after
liftoff.

+ Third and Fourth Burn
We have confirmed that the Breeze M upper stage has successfully completed its 3rd & 4th burns, 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 5th burn is scheduled for around 3:25 a.m. Eastern time, or 7:25 GMT. Separation of the Inmarsat-4 spacecraft is scheduled to follow that by about 16 minutes.

+ Stage Separations
We had a successful liftoff about 20 minutes ago of our Proton M Breeze M rocket, which is carrying the Inmarsat-4 F3 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 8 minutes. The vehicle, however, is out of range of a receiving station and we will not re-establish contact for another hour and 10 minutes. At that time we expect to receive confirmation of both the first and second burns.
