We have had a successful mission with the Proton M Breeze M rocket, carrying the Inmarsat-5 F1 satellite built by Boeing. We have had confirmation that the satellite separated from the vehicle on schedule at 10:43 p.m. EST, or 03:43 UTC, 15 hours and 31 minutes after liftoff.

Everything occurred as planned with ignition, shutdown and separation of the Proton’s first three stages. Then the Breeze M upper stage with the satellite continued the mission, igniting five times, and then releasing the satellite into transfer orbit.
