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.
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. Read more
