Lifting off from Baikonur at 01:05 am Moscow Time on Thursday, March 19, the Proton-M integrated launch vehicle (ILV) successfully orbited the Airbus DS–built Express AM-7 telecommunications satellite for Russian Satellite Communications Company (RSCC), under the Russian Federal Program, “Development of TV and Radio Broadcasting in the Russian Federation for 2009–2015”. This second launch of 2015 is the 403rd in Proton’s history.
In the course of a nominal launch, the orbital unit (the spacecraft and Breeze-M upper stage) separated from the launch vehicle at the designated time, and continued its mission. Subsequently, the spacecraft injection to the target orbit was performed based on burns of the Breeze-M upper stage main engine.

Proton was designed and is mass manufactured by the Khrunichev Space Center. The heavy-lift Proton is the mainstay of Russia’s space transport, used for inserting government and commercial payloads to low-earth and escape orbits. Proton is marked for its design, and excellent energy and performance characteristics. Proton is reputed to be one of the world’s most proven heavy-lift launchers. A modernized Proton-M using Breeze-M as the upper stage is capable of delivering 6MT+ payloads to geo-stationary orbits.
