Satellite Use:
Intelsat 31, a flexible, powerful satellite built by SSL for Intelsat. It will be co-located with Intelsat 30 at 95 degrees West longitude, where it will augment and provide redundancy and reliability for direct-to-home broadcast services. The 20-kilowatt satellite will be used by DIRECTV Latin America for high definition programming throughout Spanish-speaking South American and the Caribbean.

Mission Profile:
The Proton M launch vehicle, utilizing a 5-burn Breeze M Supersynchronous Transfer Orbit (SSTO) mission design, will lift off from Pad 24 at the Baikonur Cosmodrome in Kazakhstan, with the Intelsat 31 satellite on board. The first three stages of the Proton will use a standard ascent profile to place the orbital unit (Breeze M upper stage and the Intelsat 31 satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the orbital unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a supersynchronous transfer orbit. Separation of the Intelsat 31 satellite is scheduled to occur approximately 15 hours, 31 minutes after lift-off.

Target Orbit at Separation:
Perigee: 3503 km
Apogee: 65,000 km
Inclination: 29.6 degrees

Spacecraft Separation:
Approximately 15 hours, 30 minutes after liftoff
