Yamal-402 satellite orbit adjusted successfully - Roscosmos

A second maneuver to lift the Yamal-402 satellite into its designated orbit has been successful, a spokesman for the Russian Federal Space Agency (Roscosmos) told Interfax-AVN.

"The operation was carried out under the supervision of the Mission Control Center of Thales Alenia Space company, which built this satellite for OJSC Gazprom Space Systems. Its specialists have reported that the satellite's engines operated normally. The planned maneuver was accomplished successfully," he said.

Earlier reports said that several extra maneuvers would have to be performed, using the satellite's own engines and onboard fuel reserves, to place Yamal-402 into its designated orbit following a malfunction of the upper stage.

The upper stage failed to place the Yamal-402 communication satellite in the final orbit on Sunday. When its engine was fired for the fourth time, it operated for five instead of nine minutes and the flight sequence of the satellite was distorted. Fuel from the satellite's storages will have to be burned additionally to take it to the planned position which may reduce the service life of the satellite.

The Briz-M upper stage was designed and is serially produced at the Khrunichev Space Center. The propulsion engines for Briz-M are manufactured by the Isayev Designer Bureau in Korolyov, Moscow region.

Control over Yamal-402 will soon be transferred to Gazprom Space Systems. The satellite will offer broadcasting services in Russia, as well as countries of Western and Central Europe, the Middle East and North Africa.
