Launch of the Proton-M LV with EchoStar 21

June 8, 2017 at 6:45 Moscow Time the Proton-M launch vehicle successfully lifted off from the BAIKONUR Space Center in Kazakhstan, with the EchoStar 21 satellite on board. It was the first Proton-M launch in 2017.

The first three stages of the Proton-M used a standard ascent profile to place the orbital unit (Breeze-M upper stage and the EchoStar 21 satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze-M will perform planned mission maneuvers to advance the orbital unit first to a nearly circular parking orbit, then to an intermediate orbit, followed by a transfer orbit, and finally to a geosynchronous transfer orbit. Separation of the EchoStar XXI satellite is scheduled to occur approximately 9 hours, 13 minutes after liftoff.

EchoStar 21 is a state-of-the-art S-band satellite designed to provide mobile connectivity throughout Europe. The spacecraft, based on SSL’s 1300 bus, will be located at the 10.25° East orbital slot. EchoStar subsidiary EchoStar Mobile Limited, an EU-wide licensee for an integrated mobile satellite service network with a complementary ground component, will utilize a portion of the capacity on EchoStar 21 to provision its next-generation, all IP-enabled mobile communications network.
