Proton to Launch AsiaSat 9

Russia's Proton Rocket is ready for its fourth flight in 2017, targeting a September 28 liftoff with the AsiaSat 9 communications satellite destined for a Geostationary Transfer Orbit to embark on a 15-year mission. Carrying a tri-band communications payload, AsiaSat 9 will provide replacement and expansion coverage for the aging AsiaSat 4 satellite that is approaching the end of its planned service life.

Carrying the 6,140kg satellite, the Proton-M is set for a standard ten-minute ride into a sub-orbital trajectory before the Briz-M upper stage takes over for a five-burn, nine-hour mission profile to methodically increase the orbital altitude and reduce inclination.
