End of SIRIUS FM-5 Mission

It is the end of another successful mission here at ILS. The ILS launch team members that were planning on returning to the US, have done so. Thanks to everyone who followed along with the blog. Please stay tuned because the next launch is already in preparation.


ILS Proton Successfully Launches SIRIUS FM-5 Satellite

BAIKONUR COSMODROME, Kazakhstan, July 1, 2009 – ILS International Launch Services (ILS), a world leader in providing mission and launch services to the commercial satellite industry, successfully carried the SIRIUS FM-5 satellite into orbit today on an ILS Proton. This was the third commercial mission of the year for ILS and the fifth successful Proton launch of 2009.  ILS has launched the entire SIRIUS three-satellite constellation beginning with the first launch in 2000.


SIRIUS FM-5 Mission Success!

We have had a successful mission with the Proton M Breeze M rocket, carrying the SIRIUS FM-5 satellite built by Space Systems Loral for SIRIUS XM Radio, Inc. We have had confirmation that the satellite separated from the vehicle on schedule at 12:24 AM Eastern Time, or 04:24 GMT, 9 hours and 14 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.


SIRIUS FM-5 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 12:03 AM EDT, or 04:03 GMT. Separation of the SIRIUS FM-5 spacecraft is scheduled to follow the 5th burn completion by about 15 minutes.


SIRIUS FM-5 Second Burn Completion

As the Breeze M upper stage of our Proton M rocket continues its climb into space with the SIRIUS FM-5 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 11 minutes; after that the additional propellant tank will be jettisoned, and the 4th burn will start. All this will happen in a span of almost 15 minutes while the vehicle is again out of range of a ground station. We should reacquire the vehicle shortly after the 4th burn ends.


SIRIUS FM-5 Stage Separations

We had a successful liftoff about 15 minutes ago of our Proton Breeze M rocket, which is carrying the SIRIUS FM-5 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.
