ECHOSTAR X

Mission Profile

From its equatorial launch site at 154 degrees West Longitude, a Zenit-3SL launch vehicle lifted the EchoStar X spacecraft to a high perigee geosynchronous transfer orbit for its ultimate orbital location at 110 degrees West Longitude.

Lifting off from the Odyssey Launch Platform, the Zenit-3SL rocket began its ascent phase of flight. The first stage of the vehicle separated two-and-a-half minutes after liftoff, and then the protective payload fairing was jettisoned a minute later. Following a six-minute burn, the second stage separated from the Block DM upper stage. The Block DM then executed a five-minute burn and then shutdown for a 33-minute coast period. The Block DM ignited a second time for a five-and-a-half minute burn. After another coast lasting nearly 10 minutes, the Block DM separated from the spacecraft, above the East Coast of Africa.
