W7 Stage Separations

We had a successful liftoff about 11 minutes ago of our Proton M Breeze M rocket, which is carrying the W7 satellite. 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 7 minutes.

W7 Mission Successful!

We have had a successful mission with the Proton M Breeze M rocket, carrying the W7 satellite built by Thales Alenia Space for Eutelsat. We have had confirmation that the satellite separated from the vehicle on schedule at 6:30 p.m. EST, or 04:34 GMT, 9 hours and 12 minutes after liftoff. Everything occurred as planned with ignition, shutdown and separation of the Proton’s first three stages. Then the Breeze M upper stage with the satellite continued the mission, igniting five times, and then releasing the satellite into transfer orbit.

W7 Third and Fourth Burn Completion-

We have confirmed that the Breeze M upper stage has successfully completed its 3rd & 4th burns, as well as jettisoning its additional propellant tank. The vehicle is now in a 5-hour coast period, during which we will have nothing to report. The 5th burn is scheduled to start around 6:11 p.m. EST, or 23:11 GMT. Separation of the W7 spacecraft is scheduled to follow the 5th burn completion by about 14 minutes.

W7 Second Burn Completion

As the Breeze M upper stage of our Proton M rocket continues its climb into space with the W7 satellite, we have received confirmation that the 2nd burn of the upper stage occurred and shut down as scheduled. The next events are scheduled for about 2 hours from now. The Breeze M upper stage will ignite for a 3rd time and burn for approximately 12 minutes; after that the additional propellant tank will be jettisoned, and the 4th burn will start and complete. All this will happen in a span of almost 20 minutes while the vehicle is again out of range of a ground station. We should reacquire the vehicle shortly after the 4th burn ends.

W7 Rollout

[b]19 and 20 Nov:[/b] At the end of the second day of loading, the State Commission met and authorized the rollout of the ILV to the launch pad. The teams gathered to witness the rollout of the ILV from the Breeze M fueling station to Launch Pad 39 at 06h45 on 20 Nov. Approximately 3 hours later the team reassembled at the Pad to watch the erector lift the ILV into its new vertical position. The next days will be used for testing and finalization of the ILV and systems for launch.

Catch Up

[b]1 Nov –[/b] With the SC and PLA fitcheck confirmed successful, the KhSC team focused on Breeze-M testing for preparation to transfer to area 31 for high pressure loading (helium and propellants). After loading operations completed, the Breeze-M was transferred back to Hall 103A on 2 Nov for nominal testing. The TAS team work to prepare the SC for weighing and propellant loading operations. [b]3 to 5 Nov –[/b] The SC was authorized for fueling operations on 2 Nov. On 3 Nov MON load, 4 Nov a reconfiguration day and 5 Nov MMH load. All operations completed successfully. KhSC continued testing of the Launch Vehicle in Hall 111. In Hall 101, final closeout on the PLF and PLA and testing on the Breeze-M. [b]6 Nov –[/b] SC loading operations completed nominally yesterday. TAS worked on SC finalizations prior to joint ops and KhSC prepared the PLA and Breeze-M for mating. [b]9 Nov –[/b] Launch Vehicle is in Hall 111 completing final electrical operations. The Breeze-M final testing and transfer to tilter also occurred today. SC arming and final inspections prior to moving in Hall 103A for mating. In parallel, TAS continued their loading equipment decontamination. [b]11 Nov –[/b] Launch Vehicle final preparation in Hall 111. In Hall 101 joint operations began with the SC mating on PLA and SC/PLA mating on Breeze M. Both TAS and KhSC worked after the mating on electrical checkouts. [b]12 Nov -[/b] Joint operations continue in Hall 101. The newly assembled Orbital Unit tilted horizontal, and the fairing installation began. [b]14 Nov -[/b] Fairing finalization with logo placement and fairing sealing. The now encapsulated Ascent Unit will complete electrical testing in preparation for the transfer to Hall 111. [b]15-16 Nov –[/b] The Ascent Unit transfer to Hall 111 was successful. Mating to the Launch vehicle was nominal and SC checkouts began. After all SC checks completed, KhSC began the Integrated Launch Vehicle testing. In parallel, TAS continues SC GSE packing for return to Cannes post launch.

Stand Alone Operations and Fitcheck

23-29 Oct. Stand alone operations for Thales and KhSC. Thales performed electrical and mechanical SC checkouts and validated the fueling support equipment in Hall 103A. In parallel, KhSC worked in Hall 101 preparing for the PLA and separation system arrival (27 Oct) and the Breeze M arrival (30 Oct). After cleaning and electrical checkouts, the PLF halves are in storage in Hall 101 waiting for installation after the orbital unit is mated on the tilter. In Hall 111, KhSC finished LV pneumatic tests and will setup the electrical test configuration. RUAG specialists arrived on 27 Oct to prepare the separation system for the fitcheck on 30 Oct. 30 Oct. Fitcheck In preparation for the fitcheck, KhSC transported the PLA and separation system into Hall 103A on 29 Oct. On 30 Oct. after a pre-operation and safety meeting, Thales hoisted the SC and the operations began ([url=http://www.ilslaunch.com/assets/galleries/W7-Gallery/SC-hoisting.jpg]See photo: SC hoisting[/url]). By the end of the day, RUAG had measured, tensioned, measured again, and confirmed that things fit right into place ([url=http://www.ilslaunch.com/assets/galleries/W7-Gallery/KhSC-and-RUAG-Fitcheck.jpg]See photo: KhSC and RUAG Fitcheck[/url]). While across town, the Breeze M Upper Stage moved to the fueling station for its two days of loading. The Breeze M will be installed on the tilter on 3 Nov and begin full cycle testing. With the fitcheck complete, the Breeze M partially fuelled and the PLA back in Hall 101, the SC will finish stand alone operations before the authorization is given by Eutelsat to proceed with propellant loading operations (3 and 5 Nov).
