EUTELSAT 3B Mission Status Update

May 26, 2014

The Zenit-3SL rocket carrying the spacecraft lifted off at 14:09:59 Pacific Daylight Time (PDT) on Monday, May 26th (21:09:59 UTC, 23:09:59 CEST) from the launch platform, positioned at 154 degrees West longitude in the Pacific Ocean. One hour later, the Block DM-SL upper stage inserted the satellite, weighing 5,967 kilograms (13,155 lbs.) into geosynchronous transfer orbit, on its way to a final orbital position at 3 degrees East longitude.  Eutelsat acquired the spacecraft’s first signals from orbit shortly after spacecraft separation. All systems performed nominally throughout the launch mission.

Following suspension on 31 March of the launch campaign activities of the EUTELSAT 3B satellite, Sea Launch today announced that its prime contractor, Energia Logistics, Ltd., will this week restart testing in preparation for the rollout of the Payload Unit and its integration with the Zenit-3SL launch vehicle before departing to the launch site in mid-May.
 
The launch of the EUTELSAT 3B satellite is now scheduled for 26 May at 14:10 Pacific Daylight Time (21:10 UTC, 23:10 CEST) at the opening of a 54-minute launch window.

During the final “dry” roll-out phase of integrated launch vehicle (ILV) processing at Home Port in support of the EUTELSAT 3B mission, a discrepancy in the nominal movement of the cable-mast and the Zenit-2S LV lateral plate occurred while installing the ILV onto the launch pad. This caused mechanical damage to the lateral plate housing located on the inter-stage truss of the LV.  Resolution of this condition will result in a delay to the planned April 15, 2014 launch date.
 
A decision was made to de-mate the Payload Unit and Block-DM-SL onboard the Sea Launch Commander to resolve the issue, establish the root cause and perform additional checks of the interface between the launch vehicle and ground support equipment connectors.
 
Once the above tasks have been completed, Sea Launch will announce an updated schedule and launch day for EUTELSAT 3B.

The EUTELSAT 3B satellite was not powered on during the operation on the launch vehicle and was unaffected. It remains in a safe configuration.
