Mission Profile: The Proton launch vehicle will inject the DIRECTV-5 satellite into geosynchronous transfer orbit. The first three stages will use a standard ascent trajectory to place the Block DM upper stage with the satellite into a an elliptical parking orbit of 186.5 km by 222.2 km (116 mi x 138 mi), inclined at 51.6 degrees. Then the Block DM will ignite twice to propel the satellite to its target transfer orbit of 35,786 km x 6,600 km (22,236 mi x 4,101 mi), inclined at 17.6 degrees. Following separation from the Block DM, the spacecraft will perform a series of liquid apogee engine burns to raise perigee, lower inclination and circularize the orbit at the geostationary altitude of 36,000 km (22,300 mi).

Spacecraft Separation: Approximately 6 hours, 32 minutes after liftoff

ILS Mission Statistics:
4th ILS mission this year
2nd ILS Proton mission this year
23rd ILS mission on Proton since formation of the U.S.-Russian joint venture in 1995
