A Proton M/Breeze M integrated launch vehicle (ILV) blasted off today (at 4:12 p.m. Moscow Time) from the Baikonur launch base to deliver the six-ton Inmarsat 5F1 satellite to a super-synchronous transfer orbit (SSTO) for Inmarsat (London, Great Britain). This was the ninth Proton mission of this year.

The launch proceeded nominally.  In compliance with the mission design, the orbital unit separated from LV Stage 3 to continue flight in a self-powered mode. The subsequent injection of the spacecraft to its target orbit is to be achieved through five burns of the Breeze M main engine.  The spacecraft/upper stage separation is expected about 15h 31 min after the rocket liftoff. Separated spacecraft mass is 6100 kg.



The heavy-lift Proton M launch vehicle and the Breeze M upper stage are developed and produced by the state-run Khrunichev State Research and Production Space Center.

Inmarsat 5F1, built by U.S. company Boeing, will provide high-speed mobile broadband services to customers throughout Europe, the Middle East, Africa and Asia.

The contract to launch the Inmarsat 5F1 satellite on the Proton has been concluded by ILS-International Launch Services Inc., a world leader in providing launch services for global satellite operators. This was the seventh ILS Proton mission in 2013 year, and the 84th ILS Proton mission overall.
