SES-3 Mission Success

We have had a successful mission with the ILS Proton Rocket carrying the SES-3 satellite built by Orbital Sciences Corporation and the KazSat-2 satellite built by Khrunichev State Research and Production Space Center. We have had confirmation that the SES-3 satellite separated from the vehicle on schedule at 3:17 a.m. EDT, or 07:17 GMT, 8 hours and 01 minute after liftoff and subsequently the KazSat-2 satellite separated at 4:46 a.m. EDT or 8:46 GMT.

SES-3 Stage Separations

We had a successful liftoff about 11 minutes ago of our Proton M Breeze M rocket, which is carrying the SES-3 and KazSat-2 satellites on board. The three stages of the Proton vehicle have performed as planned, and it is up to the Breeze M upper stage to complete the mission. The upper stage has begun its first burn, which is scheduled to last around 5 minutes.

SES-3 Integrated Launch Vehicle

After the ascent unit containing the SES-3 spacecraft, the KazSat-2 SC and the Breeze M were integrated to the launch vehicle, the next step was to apply the thermal blanket to the now integrated launch vehicle, which provides a stable environment for our 2 sensitive payloads.  Once complete, the delicate operation of transferring the enormous rocket to the transporter was performed, and the huge machine was slowly moved via rail to the Breeze M fueling station where fueling took place over the course of the next two days.

Satellite Stack and Tilt

In the last two days, two more important milestones have been accomplished.  The SES-3 spacecraft (SC) was placed on top of the KazSat-2 SC, and the “stack” was tilted into a horizontal position for encapsulation into the payload fairing.  Today, the Orbital electrical team will check the internal Proton umbilical transit lines.  All operations are proceeding according to schedule and there are no issues.

SC Mate to PLA and Stack Configuration

Several campaign milestones have occurred this past week.  The SES-3 (OS-2) spacecraft (SC) was successfully mated to the payload adapter (PLA).  RUAG, Orbital and Khrunichev worked continuously for several hours, performing checks at every new step to be sure all mechanical and electrical connections were secure.   Then it was carefully lifted and placed on top of the Breeze-M/KazSat-2 stack and secured in place.  We now officially have an Ascent Unit for the first ILS Proton shared launch!
