Proton M Delivers Satellite to Target Orbit for Intelsat

26.03.2012

The Russian Proton M has successfully orbited a 6 MT Intelsat-22 communications satellite for Intelsat, Ltd, a global satellite operator (USA).

This was the second Proton launch in 2012 and 374th launch in Proton’s flight history.

A modernized Proton M carrying Intelsat-22 blasted off from Launch Pad № 39 at Baikonur on March 25 at 16:10 msk (18:10 Baikonur time).

The orbital unit was lofted using five burns of the Breeze M main engine. As per mission profile, Intelsat-22 was injected to a super-synchronous separation orbit with a 65000km apogee altitude. Subsequently the satellite traveled using its own propulsion system to the 72°E slot in the geostationary orbit.

At the required time at 07:40 msk (i.e. 15h 30min after liftoff), the spacecraft separated from the upper stage. Satellite control was transferred to the Customer.

The contract for this Proton launch was signed by the RF/US company, International Launch Services Inc. (ILS). For ILS it was the 71th commercial Proton launch.

The Proton launch vehicle and its upper stage, the Breeze M, were designed, and are serially produced, by the Khrunichev Space Center. Commercial satellites are launched into orbit by a three-stage Proton M outfitted with a Breeze M upper stage. The upgraded Proton M now has a higher carrying capacity and is able to deliver payloads in excess of 6 metric tons into a geo-transfer orbit. Proton has ample performance due to the Breeze M upper stage having broad capabilities as far as injection of spacecraft into orbits with different altitudes and inclinations is concerned.

This was the 15th Proton launch with a Boeing Satellite Systems on board, and Intelsat 22 was the 10th satellite in the global Intelsat fleet launched on ILS Proton.
