Mission Profile: The Proton launch vehicle will inject the EchoStar VIII 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 circular parking orbit of 160 km (100 mi), inclined at 51.6 degrees. Then the Block DM will ignite three times to propel the satellite to a transfer orbit of 4,300 km x 35,786 km (2,670 mi x 22,300 mi). 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 35,786 km (22,300 mi).
Spacecraft Separation: Approximately 6 hours, 36 minutes after liftoff
