The SIRIUS FM-5 satellite will supplement the existing fleet of SIRIUS satellites with a high-power geostationary satellite that enhances the listening experience. The Proton launch vehicle, utilizing a 5-burn Breeze M mission design, will lift off from Pad 39 at Baikonur Cosmodrome, Kazakhstan, with the SIRIUS FM-5 satellite on board. The first three stages of the Proton will use a standard ascent profile to place the ascent unit (Breeze M upper stage and the SIRIUS FM-5 satellite) into a sub-orbital trajectory. From this point in the mission, the Breeze M will perform planned mission maneuvers to advance the ascent unit first to a circular parking orbit, then to an intermediate orbit, followed by a transfer orbit and finally to a geo-transfer orbit. Separation of the SIRIUS FM-5 satellite is scheduled to occur approximately 9 hours, 14 minutes after liftoff. Launch is scheduled for 3:10 PM EDT US 29 June 2009.
