Statement from Khrunichev
On 9 December, during the target orbit insertion phase, the Yamal 402 spacecraft separated ahead of the scheduled time. At present the spacecraft is under control. The delta insertion profile is being currently defined for translating the spacecraft to its station and subsequent commissioning.
Early on 9 December evaluation was performed of the Yamal 402 orbit parameters. All SC systems are functioning nominally.
Experts believe two additional burns of the propulsion system will be required for the delta insertion of Yamal 402 to the design orbital slot. The first such burn is scheduled for the late Sunday-early Monday.
Following the completion of all maneuvers, the spacecraft will be handed over to OAO Gazprom Space Systems for operation as originally planned, i.e. on 8 January.
