Mission Profile: The Proton launch vehicle will inject the DIRECTV 10 satellite into geosynchronous transfer orbit. The first three stages will use a standard ascent trajectory to place the Breeze M upper stage with the satellite into a suborbital trajectory, from which the Breeze M will place itself and the spacecraft into a circular parking orbit of 173 km (107.5 mi), inclined at 48 degrees. Then the Breeze M will ignite four more times to propel the satellite to its target geosynchronous transfer orbit of 35,786 km x 4,901 km (22,236 mi x 3,045 mi), inclined at 21.4 degrees. Following separation from the Breeze M, 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 9 hours, 8 minutes, 40 seconds after liftoff
