BAIKONUR, Kazakhstan (Roscosmos PR) — Proton-M carrier rocket with the Briz-M booster successfully launched from pad No. 39 of Site No. 200 at the Baikonur Cosmodrome.
The rocket carried two Russian telecommunication satellites Ekspress-80 and Ekspress-103 built by ISS Reshetnev company (part of Roscosmos). The launch and flight of the carrier rocket went nominally.
According to the flight sequence, 587 seconds after the liftoff the space head unit (booster and two spacecraft assembly) nominally separated from the third stage of the carrier rocket.
Further injection into orbit will be ensured by the booster service propulsion system. The total injection time from the liftoff and second satellite separation will reach 18 hours, 16 minutes and 40 seconds.
Proton-M carrier rocket is manufactured by Khrunichev Center (part of Roscosmos) and has been used to inject payloads into target orbits and departure trajectories as part of federal and commercial programs since 2001.
Throughout its operation, the rocket has undergone four deep modernizations allowing substantial improvement of its thrust to weight ratio and ecological characteristics while injecting heavy single and dual payloads.
